A workstation has a network link light but cannot access internal network resources. You ping 127.0.0.1 and successfully establish your NIC is working properly. Which of the following is the MOST likely cause of the issue? A) Slow transfer speeds B) IP address conflict C) Incorrect gateway D) Packet collisions

B) IP address conflict /If the loop back address is working and the network has a good link light then this establishes that the computer has good communication capabilities. A Second step to troubleshoot network connectivity, not mentioned in this scenario, would be to ping a distant IP. If this was successful, then this would establish good connectivity to outside networks. Therefore, the inability to access internal network communications is likely an IP address conflict.

Your system applications keep crashing. The system works for email and word processing but when you open a graphics program at the same time then the applications crash. What is the likely cause? A) There is not enough memory B) Memory errors are occurring in one of the higher memory modules. C) The memory modules are incompatible with one another. D) The application is 64 bit on a 32 bit OS.

B) Memory errors are occurring in one of the higher memory modules. /Because the RAM is working for some programs such as email and word processing, the issue is not a lack of RAM, but something related to the application of RAM and the graphics program that has been installed. If the memory module were incompatible, then no programs would work. Therefore, we can deduce that there must be something wrong with the memory modules.

B) Sandbox /When enabled, The Windows OS Sandbox feature lets you launch a virtual machine that is isolated from the host system. It is fully functional. The catch is that, unlike true VMs, you cannot save the Sandbox and any changes are permanently lost when it is closed. A Secret Garden is a web portal used by shared network connections in hotels and coffee shops. OneDrive is a Microsoft cloud-based storage solution and MSVMD does not apply.

C) Change the subnet mask to 255.255.254.0. /The lowest cost solution is to borrow bits from the network segment of the subnet mask and enable the network to expand the number of available IP addresses.

After answering a service call, you find a customer's computer is dead. Which of the following checks would you perform first? A) Check to see if the power supply is functional. B) Check the CMOS battery. C) Check the AC outlet voltage. D) Check for excessive EMI.

C) Check the AC outlet voltage. /Never overlook the obvious! Perform problem determination by checking all connections first, and that includes power connections. If you find that the PC is plugged in, a faulty AC outlet would cause a dead computer. Your next step would be to verify the power supply as that could also cause a dead battery.

What is the first thing to check when a print job is stalled in a WIndows-based PC? A) Try another print driver B) Try another printer cable C) Clear the spooler D) Restart the PC

C) Clear the spooler/ The spooler service of Windows manages the printing. If a print job is stalled, it is most likely the spooler service has hung. As a first troubleshooting step, it should be restarted.

This problem is most likely: A) Power sags due to the lights B) Incorrect cable routing. C) The wrong protocol being installed. D) None of these are correct.

Incorrect cable routing /The cabling is run too close to an EMI source. The problem manifests itself only at night because that is when the lights are turned on.

Which of these choices provides the highest level of performance and redundancy? A) RAID 0 B) RAID 1 C) RAID 5 D) RAID 10

RAID 10 /RAID 0 is quite fast but provides no parity or mirroring information to recover from a drive loss and so it is not fault tolerant. RAID 1 is slightly slower because each write operation has to take place on each drive in the mirror before continuing. Although fast, RAID 5 stripes parity data across all drives and can more readily tolerate drive failures than the other types. A failed RAID 5 volume will still operate and can be rebuilt by simply replacing the failed drive. It will rebuild itself using the parity information stored on the other drives. RAID 10 (one zero or 1 + 0) provides the combination of speed and redundancy not found in other implementations. It combines the bit for bit real time redundancy not found in other implementations. It combines the bit for bit real time redundancy of mirroring (RAID 1) with the speed of striping data (RAID 0). The cost of implementation is higher due to the number of disks needed. RAID 10 is a hybrid as it combines the function of two RAID levels. Other combinations of this type exist but are outside the scope of the A+ certification exam objectives.

After booting a workstation, a "Date and Time Not Set" message appears on the screen. What is the MOST possible cause? A) The computer was not shut down properly B The CMOS battery needs to be replaced C) The OS has stopped syncing with the NTP server D) The system BIOS is corrupted
