   A developer is requesting permission to utilize client-side virtualization. The developer would like to write code in a setting isolated from other infrastructure to avoid negative impacts of experimental code. Which of the following provides the BEST solution for the developer?

   • ACross-platform functionality
   • BSoftware compatibility
   • CTest case development
   • DSandbox environment

   Show answer

   Answer: D

   Explanation

   CompTIA: "Sandbox —Create an isolated environment in which to analyze viruses, worms, and Trojans. As the malware is contained within the guest OS, it cannot infect the researcher's computer or network."

   A user takes a tablet to a technician because the cursor on it keeps drifting. The technician notices the screen does not appear to be damaged. Which of the following is the MOST likely cause of the cursor issue?

   • AThe screen is physically damaged.
   • BThe screen rotation is incorrect.
   • CThe touch-pen battery is depleted.
   • DThe screen needs to be recalibrated.

   Show answer

   Answer: D

   Explanation

   CompTIA: "On a laptop, if touchpad sensitivity is too high, typing can cause vibrations that move the cursor. Examples include the pointer drifting across the screen without any input or a 'ghost cursor' jumping about when typing. Install up-to-date drivers and configure input options to suit the user. Many laptops now come with a Fn key to disable the touchpad. If you can rule out simple hardware causes, unresponsive or inaccurate touch input can be an indication of resources being inadequate (too many open apps) or badly written apps that hog memory or other resources. A soft reset will usually fix the problem in the short term." No other options make sense for the given problem

   A user submitted a support ticket that states all of the printouts from a laser printer appear to have double images imposed on them. A review of past printer support tickets shows that a maintenance kit has not been installed in more than a year. Which of the following printer consumables is MOST likely causing the issue?

   • ASeparation pad
   • BTransfer roller
   • CInk cartridge
   • DFuser

   Show answer

   Answer: B

   Explanation

   There is a little CompTIA knowledge you need to have when taking these exams. They love to categorize common symptoms - and this is one of them. Ghosting per CompTIA is very frequently associated with drums that have not been cleaned (so the cleaning blade is bad), or the transfer roller is dirty. The reason I would not select fuser is because CompTIA prefers using this consumable in the "toner is smudging on the page after picking it up" question.

   Select 2

   Which of the following options provides correct information about 2.4GHz and 5GHz wireless frequencies? (Choose two.)

   • A2.4GHz has less interference. 5GHz transmits in lower speed.
   • B2.4GHz penetrates solid objects more effectively. 5GHz provides faster data connections.
   • C2.4GHz has a higher data rate. 5GHz has 23 channels.
   • D2.4GHz has 11 channels. 5GHz has no data interference.
   • E2.4GHz has a higher coverage area. 5GHz has higher bandwidth.
   • F2.4GHz has a higher bandwidth. 5GHz has lower transmit power.

   Show answer

   Answer: BE

   Explanation

   CompTIA: 2.4 - "The 2.4 GHz standard is better at propagating through solid surfaces, giving it the longest signal range. However, the 2.4 GHz band does not support a high number of individual channels and is often congested, with both other Wi-Fi networks and other types of wireless technology, such as Bluetooth®. Also, microwave ovens work at frequencies in the 2.4 GHz band. Consequently, with the 2.4 GHz band, there is increased risk of interference, and the maximum achievable data rates are typically lower than with 5 GHz." 5 GHz - "The 5 GHz standard is less effective at penetrating solid surfaces and so does not support the maximum ranges achieved with 2.4 GHz standards, but the band supports more individual channels and suffers less from congestion and interference, meaning it supports higher data rates at shorter ranges."

6. Question 606 · 624 in bank

   A technician is tasked with upgrading a laptop's RAM. Which of the following steps should the technician take FIRST?

   • AConfirm that both the current and new memory are from the same brand.
   • BRun a diagnostic test on the current memory.
   • CVerify the memory requirements of the motherboard.
   • DConnect an electrostatic discharge strap.

   Show answer

   Answer: C

   Explanation

   Only C makes sense. Different motherboards, such as those in laptops or different generations of motherboards, require different ram. See Topic 8C in the CompTIA A+ book for more info

7. Question 607 · 624 in bank

   A startup is looking to immediately expand its data center but does not have the personnel or space to manage everything internally. The organization has multiple small offices and remote users with large computational and storage-solution requirements. Funding is not an issue for the company. Which of the following can BEST accomplish the company's goals?

   • ASaaS
   • BIaaS
   • CISP
   • DSDN

   Show answer

   Answer: B

   Explanation

   CompTIA: "Infrastructure as a service (IaaS) is a means of provisioning IT resources, such as servers, load balancers, and storage area network (SAN) components, quickly. Rather than purchase these components and the Internet links they require, you deploy them as needed from the service provider's datacenter." IaaS would allow for robust storage and computational solutions without having to manage physical servers (see "space to manage everything").

8. Question 608 · 624 in bank

   A technician is configuring a new CAD workstation that has four large hard drives. The workstation will be used to edit large, critical files, so the storage configuration should be both fast and redundant. Which of the following RAID levels BEST meets these requirements?

   • A0
   • B1
   • C5
   • D10

   Show answer

   Answer: D

   Explanation

   The RAID level that BEST meets the requirements for a fast and redundant storage configuration for the CAD workstation is RAID 10 (also known as RAID 1+0). RAID 10 is a combination of two RAID 1 arrays. In RAID 10, data is mirrored between two disks and then striped across multiple disks for faster performance. This provides the benefit of both speed and redundancy. If one disk fails, the data can still be retrieved from the other disk in the mirror. This makes RAID 10 a good choice for critical data storage and large files such as those used in a CAD workstation.

   A technician receives a ticket that states a mobile payment device is having issues with its contactless payment feature. The device is not detecting payment options. Which of the following is the MOST likely cause of the issue?

   • ANFC
   • BBluetooth
   • CWi-Fi
   • DLightning adapter

   Show answer

   Answer: A

   Explanation

   Based on the information provided, the most likely cause of the issue with the mobile payment device's contactless payment feature not detecting payment options is a hardware problem with the NFC (Near Field Communication) component of the device.

10. Question 610 · 624 in bank

    A technician is troubleshooting an old desktop system that randomly shows a Windows BSOD or powers off unexpectedly. All system temperatures are within normal limits. Which of the following should the technician do NEXT?

    • AVisually inspect the motherboard capacitors.
    • BVerify all case fans are operational.
    • CCheck that the BIOS version supports the installed CPU.
    • DCompare the software requirements with the installed RAM.

    Show answer

    Answer: A

    Explanation

    From CompTIA: " If a component has 'blown,' it can leave scorch marks. You could also look for capacitor swelling . The capacitors are barrel-like components that regulate the flow of electricity to the system chips. If they are swollen or bulging or emitting any kind of residue, they could have been damaged or could have failed due to a manufacturing defect." B doesn't make sense as the temperatures are in normal range C doesn't make sense because the computer has used this CPU and worked before (see "old desktop system") D could make sense if a new update occurred, but since Windows Blue Screens of Death usually occur when a hardware issue is found, A fits the answer the best
