CompTIA 220-1101 Online Practice Questions and Exam Preparation

CompTIA 220-1101 Online Questions & Answers

• Question 171:

  A technician is configuring a desktop computer, and the hard drive must be encrypted. Which of the following will the technician need to verify is enabled to complete this configuration?

  A. ATX
  B. NIC
  C. TPM
  D. ARM
  C. TPM

  ---

  Explanation

  TPM stands for Trusted Platform Module, which is a hardware component that securely stores encryption keys and other sensitive data12. TPM can be used to enable hard drive encryption, which is a technology that encrypts the data stored on a hard drive using sophisticated mathematical functions34. Hard drive encryption protects the data from unauthorized access in case the hard drive is lost, stolen, or tampered with.

• Question 172:

  A user joins a conference call with a Bluetooth headset.

  Which of the following has the user created?

  A. MAN
  B. PAN
  C. SAN
  D. WAN
  B. PAN

  ---

  Explanation

  Incorrect Options:

  MAN (Metropolitan Area Network): A MAN covers a city or metropolitan area and is not relevant to Bluetooth connections.

  SAN (Storage Area Network): A SAN is used for large-scale data storage, unrelated to Bluetooth connections.

  WAN (Wide Area Network): A WAN spans large geographical areas (e.g., the internet) and is not relevant to this scenario.

• Question 173:

  An administrator wants to replace a fiber-optic cable. Which of the following should the administrator most likely use?

  A. LC
  B. Bayonet Neill Concelman
  C. RJ45
  D. DB9
  A. LC

  ---

  Explanation

  LC stands for Lucent Connector, which is a type of fiber-optic connector that uses a push-pull mechanism to connect and disconnect the cable. LC connectors are small, compact, and widely used for high-density applications, such as data centers, servers, and networks. LC connectors have a 1.25 mm ferrule that can support both single- mode and multimode fibers.

• Question 174:

  A technician upgraded the memory on a server from two 8GB sticks to eight 32GB. The server memory is now at full capacity per the user guide. When the technician powers on the system, only 128 GB of memory is recognized by the OS and the BIOS. The technician decides to upgrade to the latest version of the firmware on the system, which does not help. Next, the technician installs the memory in sets of 64GB at a time. Each individual set of 64GB is fully recognized by the server.

  Which of the following will not allow the server to recognize all of the memory installed at the same time?

  A. The power supply is not supplying enough power for the memory.
  B. The memory has too many ECC errors and is shutting down
  C. The server is overheating when all of the memory is installed.
  D. The server needs DDR4 memory, and DDR3 is installed.
  D. The server needs DDR4 memory, and DDR3 is installed.

• Question 175:

  A technician is troubleshooting a computer that has random BSOD alerts and intermittently freezes during normal use. Performance degrades as the day goes on. No new software or hardware changes have been implemented. Freezing occurs under performance-intensive operations.

  Which of the following hardware components is most likely at fault?

  A. Video card
  B. HDD
  C. RAM module
  D. TPM
  C. RAM module

  ---

  Explanation

  Comprehensive and Detailed Step-by-Step Explanation:Random BSODs (Blue Screen of Death), intermittent freezing, and degraded performance under load are common symptoms of failing or faulty RAM (Random Access Memory). Here's the reasoning:

• Question 176:

  An administrator has configured a server to host virtualizes instances. The requirements of each VM must be able to scale automatically depending on peak and off-peak usage. Which of the following terms BEST describes this type of cloud concept?

  A. Over provisioning
  B. Measured pooling
  C. Resources pooling
  D. Rapid elasticity
  A. Over provisioning

  ---

  Explanation

• Question 177:

  Which of the following are benefits of application virtualization? (Select two).

  A. The network works more quickly.
  B. Applications are easier to learn.
  C. RAM works more efficiently.
  D. The overall IT cost goes down.
  E. OS performance is superior.
  F. Upgrading applications is easier.
  D. The overall IT cost goes down.
  F. Upgrading applications is easier.

• Question 178:

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

  A. Thumbprint/retinal scan
  B. Password/password
  C. Password/thumbprint
  D. Password/PIN
  C. Password/thumbprint

  ---

  Explanation

  Two-factor authentication (2FA) is a security process that requires users to provide two different authentication factors to verify their identity. This means that in addition to providing something they know (such as a password or PIN), they must also provide something they have (such as a smart card or token) or something they are (such as a fingerprint or retinal scan). Password/thumbprint. This option meets the requirement for two-factor authentication because it combines two different types of authentication factors: something the user knows (the password) and something the user is (the thumbprint). The other options do not meet the requirement for 2FA because they either use only one type of authentication factor (A and D) or use two instances of the same type of factor (B).

• Question 179:

  An end user needs to upgrade the hard drive on a laptop and wants one that is fast and shock resistant. Which of the following is the BEST option for this end user?

  A. Hybrid HHD/SSD
  B. 5,400rpm HDD
  C. 7,200rpm HDD
  D. NVMe SDD
  D. NVMe SDD

  ---

  Explanation

  A non-volatile memory express (NVMe) solid state drive (SSD) is the best option for an end user who wants to upgrade the hard drive on a laptop and wants one that is fast and shock resistant.NVMe SSDs use flash memory and PCIe interface to achieve high performance and low latency.SSDs are also more shock resistant than hard disk drives (HDDs) because they have no moving parts.Hybrid HDD/SSD combines both technologies but does not offer the same speed or capacity as pure SSDs.A 5,400rpm HDD or a 7,200rpm HDD are slower and less shock resistant than SSDs

• Question 180:

  A user tries to turn on a computer but gets the following error message: Bootable device not found. The computer had no issues yesterday Which of the following is the most likely reason for this error?

  A. The HDD is malfunctioning.
  B. The mouse and keyboard are not connected.
  C. A misconfigured boot device is in the BIOS.
  D. The network cable is unplugged
  A. The HDD is malfunctioning.

  ---

  Explanation

  The most likely reason for this error is A. The HDD is malfunctioning.

  A bootable device not found error usually indicates that the system cannot access or detect the hard disk that contains the operating system files. This could be due to a physical or logical damage to the hard disk, such as bad sectors, corrupted partitions, or faulty cables. According to the web search results, some possible causes and solutions for this error are:

  Hard drive connection issue: Check the cabling and power supply to the hard drive and make sure they are properly connected12. Corrupt hard drive partitions: Use a Windows installation media to scan and repair the corrupt system files using the System File Checker (SFC) tool1. Damaged hard drive: Replace the hard drive with a new one and reinstall the operating system2. Incorrect boot sequence in the BIOS: Enter the BIOS or UEFI settings menu and change the boot order to make sure that the system drive is in the first position13. Damaged MBR (Master Boot Record): Use a Windows installation media to

  repair the Windows bootloader using the Diskpart tool1.
