CompTIA A+ Core 2 - #1: 30 Questions (3/3)
A customer is complaining that her laptop is too slow. You have thoroughly checked the device but cannot find anything wrong with it. Which of the following is the best thing to say NEXT? "Can you tell me more about the problem? What do you mean by 'it is acting slow'?" "I don't understand what you are complaining about; this laptop seems plenty fast to me." "Excuse me for a moment; my phone is buzzing." "I found nothing wrong with this laptop that would make it slow."
"Can you tell me more about the problem? What do you mean by 'it is acting slow'?" - When dealing with a difficult customer or situation, you should follow five key principles: (1) Do not argue with customers and/or become defensive; (2) Avoid dismissing customer problems; (3) Avoid being judgmental; (4) Clarify customer statements (ask open-ended questions to narrow the problem's scope, restate the issue, or question to verify understanding); and (5) Do not disclose experiences via social media outlets.
An employee at Dion Training complains that their smartphone is broken. They state that it cannot connect to the internet, nor can it make or receive phone calls and text messages. You ask them to start up the music player on his phone, and it opens without any issues. It appears the common issue has to do with the device's network connectivity. Which of the following is MOST likely the problem with this smartphone? The Bluetooth connection is disabled The VPN password was entered incorrectly The cellular radio in it is broken Airplane mode is enabled on the device
Airplane mode is enabled on the device - If the smartphone is functioning properly except for applications that require network connectivity, then the issue is either a misconfiguration (like enabling airplane mode by mistake), a defective cellular radio chip, or a similar issue.
You are configuring a SOHO network and only allowing specific IP addresses to access the network while blocking any IP addresses that are not on the list. Which of the following should be implemented? Blocklist Allow list MAC filtering Port forwarding
Allow list - An allow list is a form of protection where only the items identified specifically on the list are allowed, whereas all others are denied.
A user's computer is experiencing repeated BSODs and calls the service desk. The call is routed to Tier 2 support, and the Tier 2 technician is scheduled for a break in about 2 minutes when the call comes in. Which of the following actions should the technician do? Answer the phone and politely ask the user to call back later Answer the phone, put the user on hold, and help them after their scheduled break Ask another Tier 2 technician to answer the call since it will take too long to solve Troubleshoot the issue for the user regardless of how long it takes
Ask another Tier 2 technician to answer the call since it will take too long to solve - Since the Tier 2 technician already knows that this will take some time to resolve, it would be best to ask another technician to help the user since they are scheduled for their break.
Which of the following should be used to uniquely identify every piece of hardware installed on the corporate network, including servers, desktops, laptops, printers, and monitors? MAC address Location Asset ID IP address
Asset ID - The asset ID should be used to uniquely identify each piece of hardware tracked in an asset management database.
A user cannot change their iPad display from landscape to portrait when they are on the home screen. Which of the following is MOST likely the reason for this issue? NFC is disabled Developer mode is enabled Autorotate is disabled Smartphone has overheated
Autorotate is disabled - If the iPad will not change from landscape to portrait mode, it is likely that the autorotate feature has been disabled by the user accidentally. To enable autorotation, the user needs to swipe down from the top right corner of the screen to open their Control Center.
Which of the following policies or plans would describe the access requirements for connecting a user's laptop to the corporate network? Bring your own device policy Password policy Onboarding policy Remote access policy
Bring your own device policy - A bring your own device (BYOD) policy allows, and sometimes encourages, employees to access enterprise networks and systems using personal mobile devices such as smartphones, tablets, and laptops.
A user is having an issue with a specific application on their Android device. The user works for DionTraining, and every employee has the exact same model of smartphone issued by the company. Whenever the user attempts to launch the application, the app fails and generates an error message. Which of the following should the technician attempt FIRST to solve this issue? Rollback the application to the previous version Update the operating system of the two smartphones Reinstall the malfunctioning application Clear the local application cache
Clear the local application cache - To solve an issue with a mobile application, you should normally attempt the following steps. First, clear the application cache since this locally stored information can become glitchy and cause an app to crash. If you have two of the same smartphones having the same issue, it is unlikely to be the application cache causing the issue. In this case, the technician would then attempt to update the OS of the smartphones. Updating the operating system can minimize compatibility issues and fix crashing applications. Third, you can try reinstalling the application if the other two options don't work.
Which of the following Control Panel sections would a technician use to configure a Windows 10 computer to use Narrator mode to read aloud the list of files that appear on the screen to the user? File Explorer Options Ease of Access Sound Indexing Options

You are trying to copy a 4.7 GB file from your Windows laptop to an external hard drive using USB 3. The external hard drive is formatted with FAT32. Every time you attempt this copy, you receive an error. What is MOST likely the issue? USB 3 is too slow to transfer a file this large Files over 4 GB cannot be stored on a FAT32 formatted drive The external hard drive must be formatted as APFS to support this transfer The laptop must be reformatted as FAT32 to support this transfer
Files over 4 GB cannot be stored on a FAT32 formatted drive - Since this file is 4.7 GB in size, it cannot be stored as a single file on the FAT32 hard drive. The file allocation table 32-bit (FAT32) is the 32-bit file system supported by Windows, macOS, and Linux computers.

A company has had several virus infections over the past few months. The root cause was determined to be known vulnerabilities in the software applications in use by the company. What should an administrator implement to prevent future outbreaks? Incident response team Patch management Acceptable use policies Host-based intrusion detection systems

Christina recently purchased a new Android smartphone and is going on a trip. At the airport, she found a public wireless network called "FreeAirportWiFi" and connects to it. She noticed a question mark (?) icon showing in the toolbar next to the Wi-Fi icon. Christina attempts to open a webpage but gets an error of "The page cannot be displayed."

What permissions would be represented by the octal 517? r-xrwx--x r-x--xrwx rwx--xr-x --xr-xrwx
r-x--xrwx Explanation: R-X is 5, --X is 1, and RWX is 7. In Linux, you can convert letter permissions to octal by giving 4 for each R, 2 for each W, and 1 for each X. R is for read-only, W is for write, and X is for execute. The permissions strings are written to represent the owner's permissions, the group's permissions, and the other user's permissions.
