A+ 220-1102 Questions

When might you need to consult MSDS documentation?

A material safety data sheet (MSDS) should be read when introducing a new product or substance to the workplace. Subsequently, you should consult it if there is an accident involving the substance and when you need to dispose of the substance.

You are trying to troubleshoot a problem over the phone and need to get advice from your manager. How should you handle this with the customer?

Advise the customer that you will put him or her on hold while you speak to someone else, or arrange to call the customer back.

You are writing some work instructions to assist technicians with deploying new user desktops via cloning. What type of installation and boot method is this process most likely to use, and what are the boot requirements?

Cloning refers to the image deployment installation method. An image is a copy of an existing installation saved as a single file. Image deployment could use USB boot media (or even optical discs), but network boot is more likely. Network boot requires a PXE-compatible network adapter and motherboard in the computer and the boot device priority set to network/PXE. The network requires a Dynamic Host Configuration Protocol (DHCP) server plus a remote network installation server to run unattended setup and apply the image.

Users working from home need to be able to access a PC on the corporate network via RDP. What technology will enable this without having to open the RDP port to Internet access?

Configure a virtual private network (VPN) so that remote users can connect to the corporate LAN and then launch the remote desktop protocol (RDP) client to connect to the office PC.

What two types of biometric authentication mechanism are supported on smartphones?

Fingerprint recognition and facial recognition.

You receive a support call from a user who is "stuck" on a web page. She is trying to use the Back button to return to her search results, but the page just displays again with a pop-up message. Is her computer infected with malware?

If it only occurs on certain sites, it is probably part of the site design. A script running on the site can prevent use of the Back button. It could also be a sign of adware or spyware though, so it would be safest to scan the computer using up-to-date anti-malware software.

Why might a PC infected with malware display no obvious symptoms?

If the malware is used with the intent to steal information or record behavior, it will not try to make its presence obvious. A rootkit may be very hard to detect even when a rigorous investigation is made.

You are assisting a user over the phone and need to identify the edition of Windows that is installed. What step instructions must you give for the user to report this information to you?

Open the Settings app, and then select System. Select the About section, and read the text next to Edition under the Windows specifications heading.

If you suspect improper handling during installation has caused damage to a RAM module, how could you test that suspicion?

Run a Memory Diagnostic. Because this tests each RAM cell, it should uncover any fault.

How do you activate Spotlight Search using the keyboard?

COMMAND+SPACEBAR.

Why is DNS configuration a step in the malware remediation process?

Compromising domain-name resolution is a very effective means of redirecting users to malicious websites. Following malware infection, it is important to ensure that DNS is being performed by valid servers.

In which atmospheric conditions is the risk of ESD highest?

During cool, dry conditions when humidity is low. When humidity is high, the static electricity can dissipate through the moisture present in the air.

A command has generated a large amount of data on the screen. What could you add to the command to make the output more readable?

Either | more or | less.

True or false? Windows Defender Firewall cannot be disabled.

False. It is not usually a good idea to do so, but it can be disabled via Security Center or the Control Panel applet.

A security consultant has recommended blocking end-user access to the chrome://flags browser page. Does this prevent a user from changing any browser settings?

No. The chrome://flags page is for advanced configuration settings. General user, security, and privacy settings are configured via chrome://settings.

How would you update an app purchased from the Mac App Store?

Open the Mac App Store and select the Updates button.

A user calls saying that their screen occasionally goes blue, and the system shuts down. What should you advise the user to do?

Record as much information from the user's blue screen as possible, especially the STOP error number,so that you can research the error.

For which backup/restore issue is a cloud-based backup service an effective solution?

The issue of provisioning an off-site copy of a backup. Cloud storage can also provide extra capacity.

You are developing a Bash script to test whether a given host is up. Users will run the script in the following format: ./ping.sh 192.168.1.1 Within the code, what identifier can you use to refer to the IP address passed to the script as an argument?

$1 will refer to the first positional argument.

You are auditing a file system for the presence of any unauthorized Windows shell script files. Which three extensions should you scan for?

.PS1 for PowerShell scripts, .VBS for VBScript, and .BAT for cmd batch files.

What type of cryptographic key is delivered in a digital certificate?

A digital certificate is a wrapper for a subject's public key. The public and private keys in an asymmetric cipher are paired. If one key is used to encrypt a message, only the other key can then decrypt it.

What is the purpose of a KB?

A knowledge base (KB) is a reference to assist with installing, configuring, and troubleshooting hardware and software. KBs might be created by vendors to support their products. A company might also create an internal KB, populated with guidelines, procedures, information from service tickets, and answers to frequently asked questions (FAQs).

The building will house a number of servers contained within a secure room and network racks. You have recommended that the provisioning requirement includes key-operated chassis faceplates. What threats will this mitigate?

A lockable faceplate controls who can access the power button, external ports, and internal components. This mitigates the risk of someone gaining access to the server room via social engineering. It also mitigates risks from insider threat by rogue administrators, though to a lesser extent (each request for a chassis key would need to be approved and logged).

What type of account management policy can protect against password-guessing attacks?

A lockout policy disables the account after a number of incorrect sign-in attempts.

A threat actor crafts an email addressed to a senior support technician inviting him to register for free football coaching advice. The website contains password-stealing malware. What is the name of this type of attack?

A phishing attack tries to make users authenticate with a fake resource, such as a website. Phishing emails are often sent in mass as spam. This is a variant of phishing called spear phishing because it is specifically targeted at a single person, using personal information known about the subject (his or her football-coaching volunteer work).

What backup issue does the synthetic job type address?

A synthetic full backup reduces data transfer requirements and, therefore, backup job time by synthesizing a full backup from previous incremental backups rather than directly from the source data.

In AAA architecture, what type of device might a RADIUS client be?

AAA refers to Authentication, Authorization, and Accounting and the Remote Access Dial-in User Service (RADIUS) protocol is one way of implementing this architecture. The RADIUS server is positioned on the internal network and processes authentication and authorization requests. The RADIUS client is the access point, and it must be configured with the IP address of the server plus a shared secret passphrase. The access point forwards authentication traffic between the end-user device (a supplicant) and the RADIUS server but cannot inspect the traffic.

What role do barcodes play in managing inventory?

An inventory is a list of assets stored as database records. You must be able to correlate each physical device with an asset record by labeling it. A barcode label is a good way of doing this.

How do you perform a scan to identify file system errors in read-only mode?

At a command prompt, run chkdsk without any switches. Note that sfc is not the correct answer as this verifies the integrity of protected system files rather than checks the file system on a drive.

Confidentiality and integrity are two important properties of information stored in a secure retrieval system. What is the third property?

Availability—information that is inaccessible is not of much use to authorized users. For example, a secure system must protect against denial of service (DoS) attacks.

Katie works in a high-security government facility. When she comes to work in the morning, she places her hand on a scanning device installed at a turnstile in the building lobby. The scanner reads her palmprint and compares it to a master record of her palmprint in a database to verify her identity. What type of security control is this?

Biometric authentication deployed as part of a building's entry-control system.

A computer is caught in a reboot loop. It starts, shows a BSoD, and then reboots. What should you do?

Boot using a recovery tool, such as the product disc, and attempt startup repair and/or repair of the Windows installation using sfc or Windows reset.

A threat actor recovers some documents via dumpster diving and learns that the system policy causes passwords to be configured with a random mix of different characters that are only five characters in length. To what type of password cracking attack is this vulnerable?

Brute force attacks are effective against short passwords. Dictionary attacks depend on users choosing ordinary words or phrases in a password.

You have selected a secure location for a new home router, changed the default password, and verified the WAN IP address and Internet link. What next step should you perform before configuring wireless settings?

Check for a firmware update. Using the latest firmware is important to mitigate risks from software vulnerabilities.

You are troubleshooting a user device that keeps powering off unexpectedly. You run hardware diagnostics and confirm there is no component fault or overheating issue. What should your next troubleshooting step be?

Check that the device has sufficient spare storage, and check for updates. If you can't identify a device-wide fault, test to see whether the issue is associated with use of a single app.

A company wants to minimize the number of devices and mobile OS versions that it must support but allow use of a device by employees for personal email and social networking. What mobile deployment model is the best fit for these requirements?

Corporate owned, personally enabled (COPE) will allow standardization to a single device and OS. As the requirement does not specify a single device and OS, choose your own device (CYOD) would also fit.

You are completing a checklist of security features for workstation deployments. Following the CompTIA A+ objectives, what additional item should you add to the following list, and what recommendation for a built-in Windows feature or features can you recommend be used to implement it? -Password best practices -End-user best practices -Account management -Change default administrator's user account/password -Disable AutoRun/AutoPlay -Enable Windows Update, Windows Defender Antivirus, and -Windows Defender Firewall

Data-at-rest encryption. In Windows, this can be configured at file level via the Encrypting File System (EFS) or at disk level via BitLocker.

When you arrive at a customer location to service a network printer, the user is upset because the printer is not working and therefore he cannot submit his reports on time. How should you approach this user?

Demonstrate empathy with the customer's situation, use active listening skills to show that you understand the importance of the issue, and make the customer confident that you can help. Then use closed-questioning techniques to start to diagnose the problem.

You are assisting with the configuration of MDM software. One concern is to deny access to devices that might be able to run apps that could be used to circumvent the access controls enforced by MDM. What types of configurations are of concern?

Devices that are jailbroken or rooted allow the owner account complete control. Devices that allow installation of apps from untrusted sources, such as by sideloading APK packages or via developer mode, could also have weakened permissions.

Why are the actions of a first responder critical in the context of a forensic investigation? Changing the service set identifier (SSID) Disabling SSID broadcast Encryption settings Changing channels

Digital evidence is difficult to capture in a form that demonstrates that it has not been tampered with. Documentation of the scene and proper procedures are crucial.

You are reviewing a secure deployment checklist for home router wireless configuration. Following the CompTIA A+ objectives, what additional setting should be considered along with the following four settings? Changing the service set identifier (SSID) Disabling SSID broadcast Encryption settings Changing channels

Disabling guest access. It might be appropriate to allow a guest network depending on the circumstances, but the general principle is that services and access methods that are not required should be disabled.

You are working on the training documentation for help-desk agents. What should you include for dealing with difficult situations?

Do not argue with customers and/or be defensive. Avoid dismissing customer problems, and do not be judgmental. Try to calm the customer and move the support call toward positive troubleshooting diagnosis and activity, emphasizing a collaborative approach. Do not disclose experiences via social media outlets.

What two factors must a user present to authenticate to a wireless network secured using EAP-TLS?

Extensible Authentication Protocol (EAP) allows for different types of mechanisms and credentials. The Transport Layer Security (TLS) method uses digital certificates installed on both the server and the wireless station. The station must use its private key and its certificate to perform a handshake with the server. This is one factor. The user must authenticate to the device to allow use of this private key. This device authentication—via a password, PIN, or bio gesture—is the second factor.

True or false? An organization should rely on automatic screen savers to prevent lunchtime attacks.

False. A lunchtime attack is where a threat actor gains access to a signed-in user account because the desktop has not locked. While an automatic screensaver lock provides some protection, there may still be a window of opportunity for a threat actor between the user leaving the workstation unattended and the screensaver activating. Users must lock the workstation manually when leaving it unattended.

True or false? The level of risk from zero-day attacks is only significant with respect to EOL systems.

False. A zero-day is a vulnerability that is unknown to the product vendor and means that no patch is available to mitigate it. This can affect currently supported as well as unsupported end-of-life (EOL) systems. The main difference is that there is a good chance of a patch being developed if the system is still supported, but almost no chance if it is EOL.

True or false. TKIP represents the best available wireless encryption and should be configured in place of AES if supported.

False. Advanced Encryption Standard (AES) provides stronger encryption and is enabled by selecting Wi-Fi Protected Access (WPA) version 2 with AES/CCMP or WPA3 encryption mode. The Temporal Key Integrity Protocol (TKIP) attempts to fix problems with the older RC4 cipher used by the first version of WPA. TKIP and WPA1 are now deprecated.

True or false? Updates are not necessary for iOS devices because the OS is closed source.

False. Closed source just means that the vendor controls development of the OS. It is still subject to updates to fix problems and introduce new features.

True or false? Using a browser's incognito mode will prevent sites from recording the user's IP address.

False. Incognito mode can prevent the use of cookies but cannot conceal the user's source IP address. You do not need to include this in your answer, but the main way to conceal the source IP address is to connect to sites via a virtual private network (VPN).

True or false? A factory reset preserves the user's personal data.

False. Restoring to factory settings means removing all user data and settings.

True or False? You should fit an antistatic wrist strap over your clothing as this is most likely to retain a charge.

False. The conductive path will occur through your fingers as you touch electronic components. The stud in the wrist strap must make contact with your skin to drain the charge.

True or false? Under default settings, the user account added during setup is not affected by User Account Control.

False. User Account Control (UAC) is designed to prevent misuse of accounts with administrative privileges. Use of such privileges requires the user to approve a consent dialog or to enter the credentials of an administrator account. This system can be disabled via UAC settings, but it is enabled by default.

True or false? The dfrgui.exe utility should be disabled if Windows is installed to an SSD.

False. While solid state drives (SSDs) and hard disk drives (HDDs) have different mechanical and performance characteristics, it is still necessary to run the Defragment and Optimize Drives (dfrgui.exe) periodically to optimize performance.

A user is assigned Read NTFS permissions to a resource via his user account and Full Control via membership of a group. What effective NTFS permissions does the user have for the resource?

Full control—the most effective permissions are applied.

You are updating a deployment checklist for installing new workstation PCs. What are the principal environmental hazards to consider when choosing a location?

Heat and direct sunlight, excessive dust and liquids, and very low or high humidity. Equipment should also be installed so as not to pose a topple or trip hazard.

Where would you look for the option to view and configure wireless adapter status in macOS?

In the Status menu on the Menu bar, in the top-right of the screen, or in the Network prefpane.

Early in the day, a user called the help desk saying that his computer is running slowly and freezing up. Shortly after this user called, other help desk technicians who overheard your call also received calls from users who report similar symptoms. Is this likely to be a malware infection?

It is certainly possible. Software updates are often applied when a computer is started in the morning, so that is another potential cause, but you should investigate and log a warning so that all support staff are alerted. It is very difficult to categorize malware when the only symptom is performance issues. However, performance issues could be a result of a badly written Trojan, or a Trojan/backdoor application might be using resources maliciously (for DDoS, Bitcoin mining, spam, and so on).

You are documenting workstation backup and recovery methods and want to include the 3-2-1 backup rule. What is this rule?

It states that you should have three copies of your data across two media types, with one copy held offline and offsite. The production data counts as one copy.

Another user calls to say he is trying to sign-on to his online banking service, but the browser reports that the certificate is invalid. Should the bank update its certificate, or do you suspect another cause?

It would be highly unlikely for a commercial bank to allow its website certificates to run out of date or otherwise be misconfigured. You should strongly suspect redirection by malware or a phishing/pharming scam.

What feature of modern file systems assists recovery after power outages or OS crash events?

Journaling means that the file system keeps a log of updates that it can use to recover damaged data. The OS might also make use of snapshot capability to maintain a file-version history or perform continuous backups.

Advanced malware can operate covertly with no easily detectable symptoms that can be obtained by scanning the device itself. What other type of symptom could provide evidence of compromise in this scenario?

Leaked data files or personal information such as passwords.

Angel brought in the new tablet he just purchased and tried to connect to the corporate network. He knows the SSID of the wireless network and the password used to access the wireless network. He was denied access, and a warning message was displayed that he must contact the IT Department immediately. What happened, and why did he receive the message?

Mobile device management (MDM) is being used to mediate network access. The device must be enrolled with the MDM software before it can join the network.

You are pinging a host at 192.168.0.99 from a host at 192.168.0.200. The response is "Reply from 192.168.0.200: Destination host unreachable." The hosts use the subnet mask 255.255.255.0. Does the ping output indicate a problem with the default gateway?

No. The hosts are on the same IP network (192.168.0.0/24). This means that 192.168.0.200 does not try to use a router (the gateway) to send the probes. 192.168.0.200 uses address resolution protocol (ARP) to find the host with the IP 192.168.0.99. The host unreachable message indicates that there was no response, but the problem will be an issue such as the host being disconnected from the network or configured to block discovery rather than a gateway issue.

An employee has a private license for a graphics editing application that was bundled with the purchase of a digital camera. The employee needs to use this temporarily for a project and installs it on her computer at work. Is this a valid use of the license?

No. The license is likely to permit installation to only one computer at a time. It might or might not prohibit commercial use, but regardless of the license terms, any installation of software must be managed by the IT department.

You are supporting a home user with upgrading a computer from Windows 10 to Windows 11. You have run Microsoft's PC Health Check tool, and it verifies that the computer meets the hardware requirements. Should you now proceed with the in-place upgrade?

No. You must backup user data and settings first. A backup is essential as a security precaution.

You are monitoring system performance and notice that a substantial number of page faults are occurring. Does this indicate that a memory module is faulty?

No—it shows the system is using the pagefile intensively and could benefit from more system RAM being installed.

You are supporting a user who has installed a vendor keyboard driver. The keyboard no longer functions correctly. Under Windows 10, what are the steps to revert to the previous driver?

Open Device Manager from the WinX menu, Instant Search, or the Computer Management console. Expand Keyboards, then right-click the device and select Properties. On the Driver tab, select Roll Back Driver.

You are attempting to run a command but receive the message "The requested operation requires elevation." What must you do to run the command?

Open a new command prompt window with sufficient privileges. You can right-click the Command Prompt icon and select Run as administrator or press CTRL+SHIFT+ENTER to execute the icon or cmd.exe command.

You are updating data handling guidance to help employees recognize different types of regulated data. What examples could you add to help identify healthcare data?

Personal healthcare data is medical records, insurance forms, hospital/laboratory test results, and so on. Healthcare information is also present in de-identified or anonymized data sets.

A different user wants to configure a multiplayer game server by using the DMZ feature of the router. Is this the best configuration option?

Probably not. Using a home router's "demilitarized zone" or DMZ host option forwards traffic for all ports not covered by specific port-forwarding rules to the host. It is possible to achieve a secure configuration with this option by blocking unauthorized ports and protecting the host using a personal firewall, but using specific port-forwarding/mapping rules is better practice. The most secure solution is to isolate the game server in a screened subnet so that is separated from other LAN hosts, but this typically requires multiple router/firewalls.

You are monitoring CPU Usage and notice that it often jumps to 100% and then falls back. Does this indicate a problem?

Probably not—CPU Usage usually peaks and falls. If it stays over 80-90%, the system could require a faster CPU, or if it spikes continually, there could be a faulty application.

A file is secured with the numeric permissions 0774. What rights does another user account have over the file?

Read-only.

You are joining a new startup business that will perform outsourced IT management for client firms. You have been asked to identify an appropriate software solution for off-site support and to ensure that service level agreement (SLA) metrics for downtime incidents are adhered to. What general class of remote access technology will be most suitable?

Remote monitoring and management (RMM) tools are principally designed for use by managed service providers (MSPs). As well as remote access and monitoring, this class of tools supports management of multiple client accounts and billing/reporting.

You are troubleshooting a print problem, which turned out to be caused by user error. The user is not confident that the problem is solved and wants more reassurance. You have already explained what the user was doing wrong in some detail. What should you do?

Run through the print process step-by-step to show that it works. It is very important to get a customer's acceptance that a problem is closed.

You have a computer with two SATA disks. You want to evaluate the performance of the primary disk. How would you select this in Performance Monitor, and what might be appropriate counters to use?

Select the Physical Disk object, select the counter, and then select the 0 C: instance. Counters that are useful for evaluating performance include % Disk Time and Average Disk Queue Length.

You are writing work instructions for third-party app deployments using the CompTIA A+ objectives to guide you. In the section on system requirements for applications, you have covered the following topics: 32-bit- vs. 64-bit-dependent application requirements Dedicated graphics card vs. integrated (VRAM requirements) RAM requirements CPU requirements External hardware tokens What additional topic should you include, if any?

Storage requirements. Each app takes up a certain amount of space when installed to the fixed disk. Also, you must plan for user-generated file storage, temp files, log files, and other data generated through use of the app.

In terms of system hardware, what is the main advantage of a 64-bit version of Windows?

Support for more than 4 GB RAM.

You are assisting with the development of end-user security awareness documentation. What is the difference between tailgating and shoulder surfing?

Tailgating means following someone else through a door or gateway to enter premises without authorization. Shoulder surfing means covertly observing someone type a PIN or password or other confidential data.

A security consultant has recommended more frequent monitoring of the antivirus software on workstations. What sort of checks should this monitoring perform?

That the antivirus is enabled, is up to date with scan engine components and definitions, and has only authorized exclusions configured.

What primary indicator must be verified in the browser before using a web form?

That the browser address bar displays the lock icon to indicate that the site uses a trusted certificate. This validates the site identity and protects information submitted via the form from interception.

Your company is replacing its Windows desktops with Mac workstations, and you need to assist users with the transition. What is the equivalent of File Explorer in macOS?

The Finder.

You are assisting another user who is trying to configure a static IP on a Windows workstation. The user says that 255.255.255.0 is not being accepted in the prefix length box. Should the user open a different dialog to complete the configuration or enter a different value?

The Network & Interface settings Edit IP settings dialog can be used. 255.255.255.0 is the subnet mask in dotted decimal format. The dialog just requires the number of mask bits. Each "255" in a dotted decimal mask represents 8 bits, so the user should enter 24.

You are repurposing an old computer. You perform a clean OS install using optical media. During setup, you configured the partition manager to apply GPT style. After the file copy stage, the new installation fails to boot. What is the likely cause?

The PC is set to boot using the legacy BIOS method. This is not compatible with GPT-style partitioning. If supported by system firmware setup, switch to UEFI boot. If the firmware is BIOS only, change the boot method back to optical disc, run setup again, and choose MBR partitioning.

What are the prerequisites for joining a computer to a domain?

The computer must be running a supported edition of Windows (Pro, Enterprise, or Education). The PC must be configured with an appropriate IP address and have access to the domain DNS servers. An account with domain administrative credentials must be used to authorize the join operation.

What are the requirements for configuring fingerprint authentication via Windows Hello?

The computer must have a fingerprint reader and a trusted platform module (TPM). Windows Hello must first be configured with a personal identification number (PIN) as a backup method.

You are troubleshooting an issue with a wireless adapter. When you open Device Manager, you find the device's icon is shown with a down arrow superimposed. What does this mean, and why might this configuration have been imposed?

The icon indicates that the device has been disabled. It could be that there was a fault, or there may be a network configuration or security reason for disabling the adapter. In this sort of situation, use incident logs and device documentation to establish the reason behind the configuration change.

A customer asks whether an iOS app that your company developed will also work on her Apple macOS computer. What issue does this raise, and what answer might you give?

The issue here is compatibility between different operating systems. Even though both are produced by Apple, iOS and macOS use different environments, so the iOS app cannot necessarily be installed directly. Your company might make a macOS version. However (do not worry if you did not include this in your answer), with the latest versions of macOS, there is support for native iOS apps, so this might be something you can offer.

What care should you take when lifting a heavy object?

The main concern is damaging your back. Lift slowly and use your legs for power, not your back muscles.

Apart from Windows and macOS, what operating system options are there for client PCs installed to a local network?

The other main choice is one of the distributions of Linux. A company might also use some sort of UNIX. Finally, Chrome OS is installed on Chromebox PCs. These are often used by educational institutions and businesses that rely primarily on web applications rather than locally installed desktop software.

A company must deploy custom browser software to employees' workstations. What method can be used to validate the download and installation of this custom software?

The package can be signed using a developer certificate issued by a trusted certificate authority. Alternatively, a cryptographic hash of the installer can be made, and this value can be given to each support technician. When installing the software, the technician can make his or her own hash of the downloaded installer and compare it to the reference hash.

While you are assigning privileges to the accounting department in your organization, Cindy, a human resource administrative assistant, insists that she needs access to the employee records database so that she can fulfill change of address requests from employees. After checking with her manager and referring to the organization's access control security policy, you discover that Cindy's job role does not fall into the authorized category for access to that database. What security concept are you practicing in this scenario?

The principle of least privilege.

You take a support call where the user doesn't understand why a program runs at startup when the Startup folder is empty. What is the likely cause, and how could you verify this?

The program has added a registry entry to run at startup. You could check this (and optionally disable the program) by using Task Manager.

Which Windows command is probably best suited for scripting file backup operations?

The robocopy command offers more options than those offered by the xcopy command, so it will usually be the better choice. The copy command is quite basic and probably not suitable.

While troubleshooting an issue with a graphics card in Windows 10, you discover that the driver version is not up to date. What first step could you perform to install the latest driver?

While troubleshooting an issue with a graphics card in Windows 10, you discover that the driver version is not up to date. What first step could you perform to install the latest driver?

You are writing a tech note to guide new technicians on operational procedures for working with Active Directory. As part of this note, what is the difference between the gpupdate and gpresult commands?

gpupdate is used to refresh local policy settings with updates or changes from the policy template. gpresult is used to identify the Resultant Set of Policies (RSoP) for a given computer and/or user account.

A DHCP server has been reconfigured to use a new network address scheme following a network problem. What command would you use to refresh the IP configuration on Windows client workstations?

ipconfig /renew

Which Linux command will display detailed information about all files and directories in the current directory, including system files?

ls -la

What command could you use to move a file names.doc from your current directory to the USB stick linked to folder /mnt/usb?

mv names.doc /mnt/usb

You are checking that a remote Windows workstation will be able to dial into a web conference with good quality audio/video. What is the best tool to use to measure latency between the workstation's network and the web conferencing server?

pathping measures latency over a longer period and so will return a more accurate measurement than the individual round trip time (RTT) values returned by ping or tracert.

What command would allow you to delete the contents of the folder /home/jaime/junk and all its subdirectories?

rm -r /home/jaime/junk

Which Linux command allows a user to run a specific command or program with superuser/root privileges?

sudo
