CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 191:

  Which of the following allows all VMs in a virtual environment to have RAM allocated for use?

  A. Measured service

  B. Containerization

  C. Synchronization

  D. Resource pooling

  Correct Answer: D

  The concept described in the question is related to virtualization and resource management in a virtual environment. The approach that allows all virtual machines (VMs) to have memory (RAM) allocated for use is known as resource pooling.

  Therefore, the correct answer is D: "Resource pooling." This approach allows resources to be allocated dynamically to VMs based on their current needs, and ensures that resources are used efficiently in the virtual environment.

  Resource pooling is a technique used in virtualization to share resources among multiple virtual machines (VMs). With resource pooling, RAM can be allocated dynamically to VMs as needed, allowing all VMs in a virtual environment to have

  RAM allocated for use. References: https://en.wikipedia.org/wiki/Resource_pooling

  Which of the following are default ports for HTTP and HTTPS traffic? (Select TWO).

  A. 23

  B. 25

  C. 80

  D. 143

  E. 389

  F. 443

  Correct Answer: CF

• Question 193:

  Which of the following network services allows a networked device to always be assigned the same IP address based on the device's MAC address?

  A. DHCP

  B. LDAP

  C. UTM

  D. DNS

  Correct Answer: A

  Dynamic Host Configuration Protocol (DHCP) allows a networked device to always be assigned the same IP address based on the device's MAC address. DHCP can also assign other network configuration settings to devices automatically.

• Question 194:

  A technician is selling up a projector (or a videoconferencing system. When the user all empts to connect a laptop to the system, the system displays the following error message.

  No source found

  The user tries multiple cables and inputs on the projector. Which of the following should the user try NEXT?

  A. Check the bulb on the projector and replace it with a new one.

  B. Check the display settings on the computer and set them to extend/duplicate.

  C. Replace the projector with another known-good one and try again.

  D. Replace the video card on the machine that is plugged in to the projector, as it has gone bad.

  Correct Answer: B

  If a user is unable to connect a laptop to a projector or videoconferencing system and sees the error message "No source found," the next step should be to check the display settings on the computer and set them to extend/duplicate. This will ensure that the laptop's display is being output to the external device. References: CompTIA A+ Certification uide, pg. 514

• Question 195:

  A university student was able to boot from a live Linux CD on a computer in a shared space on campus. Which of the following will BEST prevent this type of action from occurring in the future?

  A. Require TPM security features.

  B. Set a boot password.

  C. Disable all media options.

  D. Enable secure boot.

  Correct Answer: D

  Enabling secure boot will verify the digital signature of the bootloader and operating system, ensuring that the system only boots from trusted and authorised sources. This can prevent booting from an unauthorised live CD or other external media. The best way to prevent booting from a live Linux CD on a computer in a shared space on campus is to enable secure boot. Secure boot is a feature that ensures that the system only runs software that is signed by an authorized party. This means that the system will not boot from any unauthorized media, including live Linux CDs. Secure Boot is a feature that ensures that the system only runs software that is signed by an authorized party. This means that the system will not boot from any unauthorized media, including live Linux CDs. Secure Boot is an important security feature designed to prevent malicious software from loading when your PC starts up (boots)1. Booting from a live Linux CD is a process that allows you to run a Linux operating system from a CD or DVD without installing it on your hard drive. This can be useful for testing or troubleshooting purposes. To boot from a live Linux CD, you need to insert the CD or DVD into your computer's CD/DVD drive and restart your computer. Most systems are set up to automatically boot from the CD/DVD drive, but if your system is not set up this way, you may need to change a system setting to boot from a Linux CD/DVD23.

• Question 196:

  A salesperson is using a weather application on a mobile device. The application appears to be draining the device's battery very quickly. Which of the following is the BEST action for the salesperson to take in order to view weather forecasts while travelling?

  A. Enable the GPS service to ensure accurate location detection.

  B. Manually enter office locations in the weather application.

  C. Configure less frequent location checks using cellular location services.

  D. Use the offices' Wi-Fi IP addresses as the geolocation mechanism.

  Correct Answer: C

  The weather application could be draining the battery quickly because it is constantly checking for the user's location using cellular location services. To resolve this issue, the salesperson can configure the weather application to check for location less frequently, or turn off location services when not needed. This way, the application will not be constantly using the battery by checking for location updates, thus extending the device's battery life.

• Question 197:

  Vertical streaks are appearing on the output of a laser printer. Which of the following items is the MOST likely cause?

  A. Roller

  B. Drum

  C. Transfer belt

  D. Ribbon

  Correct Answer: B

  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. Vertical streaks on a laser printer output are usually caused by a damaged or worn-out drum, which is responsible for transferring toner to the paper. If the drum is damaged, toner may accumulate on certain parts of the drum, leading to streaks on the printed output. References: CompTIA A+ Certification All-in-One uide, Tenth Edition, Chapter 15

• Question 198:

  Which of the following is a method that can be used to securely connect a remote user's laptop to a corporate server?

  A. WAN

  B. VPN

  C. SSL

  D. DHCP

  Correct Answer: B

  A Virtual Private Network (VPN) is a secure method for connecting a remote user's laptop to a corporate server. VPNs use encryption to protect data transmitted over the internet.

• Question 199:

  A technician was called in to look at a user's PC. The user reported the PC was very sluggish. The HDD light on the PC was constantly on without blinking. The PC itself was slow receiving input and took a very long time to load the OS. The technician also noticed updates had failed. Which of the following is MOST likely the cause of these issues?

  A. The hard disk drivers have been corrupted

  B. The HDD cables need reseating.

  C. A RAID disk failed.

  D. The HDD has no free space.

  Correct Answer: D

  If a user's PC is very sluggish, the HDD light on the PC is constantly on without blinking, the PC itself is slow receiving input, and it takes a very long time to load the OS, the HDD has no free space is most likely the cause of these issues. When the hard disk drive (HDD) has no free space, the computer may become slow and unresponsive. The technician should check the amount of free space on the HDD and delete any unnecessary files to free up space.

• Question 200:

  A new version of Windows was released and a piece of software vital to the engineering department will not run on the new version. Which of the following is the BEST option to enable this department to be able to continue using this software?

  A. Do not upgrade any workstations within the organization.

  B. Upgrade all workstations and provide a virtual environment for the legacy software.

  C. Upgrade all workstations except those used by the engineering department.

  D. Purchase new workstations for the engineering department.

  Correct Answer: B

  Upgrading all workstations and providing a virtual environment for the legacy software is the best option, as it allows the engineering department to continue using the vital software while also upgrading to the latest version of Windows. This also ensures that the rest of the organization can take advantage of the latest software and security features.
