   Several users who share a multifunction printer in an office have reported unintended, thin, vertical lines that cover the entire height of every page printed from the printer. Which of the following steps should a technician complete in order to MOST likely resolve this issue?

   • AReplace the printer paper with a new ream.
   • BClear the print spooler on each computer.
   • CReinstall the printer driver on each computer.
   • DPerform the drum-cleaning procedure.

   Show answer

   Answer: D

   Explanation

   From CompTIA's book: "Vertical or horizontal lines—Marks that appear in the same place (referred to as repetitive defects) are often due to dirty feed rollers (note that there are rollers in the toner cartridge and fuser unit too) or a damaged or dirty photosensitive drum."

   While implementing a non-carrier-grade wireless backhaul, a technician notices the current channel selection is extremely polluted with various RF signals. Upon performing a spectral analysis, the technician discovers a channel containing almost no RF pollution. Unfortunately, the technician is unable to select that channel. Which of the following is the MOST likely reason for this issue?

   • AThe channel is reserved for licensed band use.
   • BThe channel selection is defective; contact the manufacturer.
   • CThe channel must be unlocked by the vendor.
   • DThe device requires a firmware update to unlock the channel.

   Show answer

   Answer: A

   Explanation

   The 2. band is subdivided into up to 14 channels, spaced at 5 MHz intervals from 2412 MHz up to 2484 MHz. Wi-Fi requires bandwidth of approximately 20 MHz, not 5 MHz. Consequently, a site designer needs to choose the channels that do not overlap. On a WLAN where only the first 11 channels are available, channels 1, 6, and 11 can be selected as non-overlapping. Note: In the Americas, regulations permit the use of channels 1-11 only, while in Europe, channels 1-13 are permitted. In Japan, all 14 channels are permitted. Those channels are reserved.

3. Question 593 · 624 in bank

   Which of the following should the data center hardware technician implement to ensure maximum uptime for customers' virtual machines?

   • ALine conditioner
   • BAC voltage regulator
   • CUninterruptible power supply
   • DCloud storage backup

   Show answer

   Answer: C

   Explanation

   C. Uninterruptible power supply (UPS) should be implemented by the data center hardware technician to ensure maximum uptime for customers' virtual machines. A UPS provides backup power to the data center in case of a power outage, allowing virtual machines to continue running without interruption. This helps ensure that customers' data and applications are not lost or impacted by power outages, and that the virtual machines are available and accessible when needed. A line conditioner helps to regulate the incoming voltage and protect the equipment from power spikes and surges, which can help to improve equipment reliability. An AC voltage regulator can also help to regulate the incoming voltage, but a UPS provides a more comprehensive solution for protecting against power outages. Cloud storage backup is important for data protection, but it does not directly help to ensure maximum uptime for virtual machines. While cloud storage backup can provide data protection in case of a data center outage, the virtual machines themselves may still be unavailable during a power outage.

   A technician needs to improve a workstation's overall response time for frequently used applications and data without removing the current hard drive. Which of the following storage devices should the technician install to BEST accomplish the objective?

   • AM.2
   • BSAS
   • CHDD
   • DSCSI

   Show answer

   Answer: A

   Explanation

   This is another poorly written question/answer bank. M.2 is a form factor, it is not in itself a storage device. Yes, it is commonly used with SSDs but the question is asking for a storage device, not a form factor. The answer bank option should say "M.2 SSD". I mean really HDD is the only option provided that is actually a storage device, but I believe this is just a poorly edited answer bank and M.2 is the partially correct answer. Hopefully the real exam doesn't include this question or has an amended version of it.

   A technician is setting up a device to use two-factor authentication. Which of the following meets this requirement?

   • AThumbprint/retinal scan
   • BPassword/password
   • CPassword/thumbprint
   • DPassword/PIN

   Show answer

   Answer: C

   Explanation

   For mfa, comptia only really cares that the factors of authentication are different and not the same. They're not really interested in the actual authentication methods so... A. Thumbprint/retinal scan = Something you are/Something you are (Same) B. Password/password = Something you know/Something you know (Same) C. Password/thumbprint = Something you know/Something you are (Different) D. Password/PIN = Something you know/Something you know(Same) Option C makes the most sense here

6. Question 596 · 624 in bank

   Which of the following BEST describes the main function of a web server?

   • AStoring files and controlling user access
   • BSetting up personal mailboxes and calendars
   • CProviding IP addresses and printing services
   • DHosting home pages and business portals

   Show answer

   Answer: D

   Explanation

   Going with D: Web servers mainly host websites and web apps and provide them to clients, everything else would be secondary functions in terms of a web server. Yes, they can store files but it's generally hosting files to either be served to a client (like serving up a home page) or used to run the web app. Controlling user access could make sense for managing user access to certain resources on the server, like files, but that's definitely not what web servers are known for. The other given options are functions that servers in general can do, but they generally involve deploying different types of servers to accomplish these functions, which a web server isn't really needed for.

   A user brings an older laptop to the help desk and reports issues with the keyboard. Upon inspection, the technician does not see any external damage but notices that many keystrokes do not register in a word processor. The laptop works fine when the technician tests it with an external keyboard. Which of the following actions would MOST likely resolve the issue?

   • ADisable the sticky keys feature.
   • BClean the keyboard.
   • CReset the BIOS settings to default.
   • DCharge the laptop.

   Show answer

   Answer: B

   Explanation

   B. Clean the keyboard. In this scenario, the laptop works fine when the technician tests it with an external keyboard, but many keystrokes do not register in a word processor when the internal keyboard is used. This suggests that the issue may be related to the internal keyboard and not the software or hardware settings. Cleaning the keyboard is a simple and effective solution to address common issues such as dirt, debris, or stuck keys that can prevent the keyboard from functioning correctly. Disabling the sticky keys feature will not likely resolve the issue, as it is designed to assist users who have difficulty pressing multiple keys simultaneously. Resetting the BIOS settings to default may resolve certain hardware or software issues, but it is unlikely to address an issue with a physical component such as the keyboard. Charging the laptop may resolve some performance issues that are related to a low battery, but it is not likely to resolve an issue with the keyboard.

   An administrator is configuring a corporate-owned smartphone for a new manager. The company requires the ability to wipe the phone's data remotely in the event of loss or theft and the capability to approve applications installed on the phone. Which of the following tools would BEST meet this need?

   • ATethering to a corporate-owned laptop
   • BWPA2-Enterpise wireless
   • CCorporate enterprise email
   • DMobile device management

   Show answer

   Answer: D

   Explanation

   D. Mobile device management. A mobile device management (MDM) solution is specifically designed to provide centralized control over mobile devices and to help ensure the security and compliance of corporate data. An MDM solution can provide the ability to wipe the phone's data remotely in the event of loss or theft, and the capability to approve applications installed on the phone, which meets the requirements mentioned in the question. Tethering to a corporate-owned laptop, WPA2-Enterprise wireless, and corporate enterprise email can provide security and management capabilities, but they may not have the comprehensive control and management capabilities of a full-featured MDM solution.

9. Question 599 · 624 in bank

   A user reports that printed receipts have black smudges over the entire image. The text is still present but is very dark and sometimes illegible. Which of the following are the MOST likely cause and solution for the printer issue?

   • AThe ribbon is jammed and is rubbing on the paper. Clear the bad ribbon and feed it through properly.
   • BThe printhead is too hot. Adjust the temperature down and retry printing.
   • CThe printer is loaded with the wrong type of paper. Replace the receipt paper with carbon paper.
   • DThe blue ink cartridge was loaded with black ink. Put in the correct ink and clean the printhead.

   Show answer

   Answer: B

   Explanation

   Receipts are printed via a thermal printer. Thermal printers work by heating a paper in specified areas in order to create an image. The specific component that does this is a thermal printhead. Since the image appears to have black smudges and is too dark, we know the thermal printhead is too hot since the capability of precise heating has diminished

    Select 2

    A user requested upgrades to a company-issued laptop to increase its performance while working with a large database stored on drive C: Which of the following tasks should a systems administrator complete to BEST meet this goal? (Choose two.)

    • AConfigure RAID 1.
    • BInstall a hybrid drive.
    • CUpgrade to 1GB NIC.
    • DIncrease the RAM.
    • EMigrate to a SSD.
    • FUpgrade the power supply.

    Show answer

    Answer: DE

    Explanation

    The two tasks that a systems administrator should complete to best meet the goal of increasing the laptop's performance while working with a large database stored on drive C are: D. Increase the RAM: Adding more RAM will allow the laptop to handle larger amounts of data and programs more efficiently, which will result in faster processing times. E. Migrate to an SSD: An SSD (Solid State Drive) is faster than a traditional hard disk drive and can significantly improve the speed of accessing files and programs, resulting in faster boot times and faster access to the large database stored on drive C. Therefore, options D and E are the correct answers. The other options, such as configuring RAID 1, installing a hybrid drive, upgrading to 1GB NIC, upgrading the power supply, may provide benefits but are less likely to have a significant impact on the laptop's performance when working with a large database stored on drive C.
