CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 41:

  A technician needs to increase the available RAM on a virtual workstation. Which of the following should the technician do?

  A. Increase the ECC memory timings in the BIOS.

  B. Upgrade to the latest DDR5 modules.

  C. Clear the temporary files on the workstation's boot drive.

  D. Use a hypervisor to adjust the resource allocation.

  Correct Answer: D

  A hypervisor is a software layer that manages and allocates resources for virtual machines (VMs) on a physical host machine. A technician can use a hypervisor to adjust the resource allocation for a virtual workstation, such as increasing the

  amount of RAM assigned to it from the available pool of memory on the host machine. This can improve the performance and functionality of the virtual workstation without requiring any hardware changes or modifications.

• Question 42:

  A company would like to take advantage of the cost savings of cloud computing by only paying for the resources used. Which of the following will BEST address this need?

  A. Shared resources

  B. Rapid elasticity

  C. Metered utilization

  D. High availability

  Correct Answer: C

  Metered utilization is a cloud feature that allows cloud providers to charge customers based on their actual consumption of resources, such as CPU time, storage space, bandwidth, or transactions.This enables customers to pay only for the

  resources they use, rather than a fixed or flat rate, which can reduce costs and increase efficiency. Metered utilization can also provide more transparency and accountability for both cloud providers and customers, as they can track and

  monitor their resource usage and billing.

• Question 43:

  Which of the following components houses the MX record?

  A. DNS

  B. VLAN

  C. DHCP

  D. SMTP

  Correct Answer: A

  The MX record is housed in the DNS (Domain Name System) which is responsible for translating domain names into IP addresses and vice versa. The MX record specifies the mail server responsible for accepting email messages on behalf of a domain name and is a resource record in the DNS123.

• Question 44:

  An IT technician is working on a help desk ticket concerning a user's inability to create a virtual machine. The technician has already checked the RAM and HDD space in the user's machine. Which of the following settings should the technician check NEXT to help troubleshoot the issue?

  A. BitLocker

  B. MSConfig

  C. BIOS

  D. Secure Boot

  Correct Answer: C

  One of the possible settings that could prevent a user from creating a virtual machine is BIOS (Basic Input/Output System). BIOS is a firmware that controls how hardware components interact with each other and with software applications. Some BIOS settings may need to be changed or enabled to allow virtualization, such as VT-x (Intel Virtualization Technology) or AMD-V (AMD Virtualization). The other options are not related to virtualization settings. Verified References: [How To Enable Virtualization In BIOS Settings].

• Question 45:

  A business purchased a new multifunction printer that will be used to photocopy documents with hundreds of pages. A technician is configuring the printer. Which of the following features should the technician ensure is set up?

  A. SMB

  B. PCL

  C. ADF

  D. SSH

  Correct Answer: C

  Automatic document feeder (ADF) is a feature that allows a multifunction printer to photocopy documents with hundreds of pages automatically without requiring manual intervention. ADF scans multiple pages from a stack of documents and feeds them into the printer one by one. SMB is a network protocol that allows file sharing and printer access among different devices on a network. PCL is a printer language that controls how data is formatted for printing. SSH is a network protocol that allows secure remote access to another device over an encrypted connection.

• Question 46:

  A customer has a Wi-Fi-capable laptop to use when traveling for work

  Which of the following will allow the laptop to stay connected when the user travels?

  A. Cellular card

  B. Wi-Fi extender

  C. Bluetooth

  D. GPS

  Correct Answer: A

  A cellular card is a device that allows a laptop to connect to the internet using a cellular network, such as 4G or 5G. A cellular card can provide internet access when the user travels and does not have access to a Wi-Fi network. A cellular card may require a subscription plan from a cellular service provider. A Wi-Fi extender is a device that boosts the signal of an existing Wi-Fi network, but it does not provide internet access by itself. Bluetooth is a wireless technology that allows devices to communicate over short distances, but it does not provide internet access either. GPS is a satellite-based system that provides location and navigation information, but it does not provide internet access as well. References: https://www.comptia.org/blog/what-is-a-cellular-card

• Question 47:

  Which of the following should the systems administrator do to reduce the number of help desk tickets submitted?

  A. Implement single sign-on.

  B. Enable multifactor authentication.

  C. Configure biometric authentication.

  D. Remove complex password requirements.

  Correct Answer: A

• Question 48:

  A. LCD power inverter

  B. AC adapter

  C. Battery

  D. Processor

  E. VGA card

  F. Motherboard

  G. Backlit keyboard

  H. Wireless antenna

  Correct Answer: ACF

• Question 49:

  Which of the following devices can utilize VLANs to secure networks?

  A. Switch

  B. Hub

  C. Repeater

  D. Bridge

  Correct Answer: A

• Question 50:

  A systems administrator receives a notification from the RAID controller that the RAID 5 array is degraded. Upon logging into the server, the administrator sees that on local disk 0, physical disk 2 has failed. Which of the following is the BEST course of action to take to resolve the problem?

  A. Schedule system downtime and replace physical disk 2. Wait until the array is rebuilt and confirm in the RAID controller that the system is no longer degraded.

  B. Immediately replace physical disk 2. Wait until the arrays is rebuilt and confirm in the RAID controller that the system is no longer degraded.

  C. Delete logical disk 0 and manually configure a new RAID array only using the known- good working drives. Wait until the array is rebuilt and confirm in the RAID controller that the system is no longer degraded.

  D. In the controller, convert the RAID 5 array to RAID 0 array to avoid system downtime. Wait until the array is rebuilt and confirm in the RAID controller that the system is no longer degraded.

  Correct Answer: A
