CompTIA 220-1101 Online Questions & Answers

• Question 1051:

  A technician is using a PAN to connect a group of users on a field project. Which of the following services should the technician activate on the mobile device to share the internet data connection?

  A. Tethering
  B. Pairing
  C. Bluetooth
  D. Hotspot
  D. Hotspot

  ---

  Explanation

  To share the internet data connection with a group of users on a field project, the technician should activate the hotspot feature on the mobile device. Hotspot functionality allows the device to act as a wireless access point, enabling other devices to connect to it and share its internet connection. Tethering is a similar concept but often refers to connecting a device to another via USB or Bluetooth to share the internet connection. In this context, hotspot (option D) is the most appropriate choice for connecting a group of users.

• Question 1052:

  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
  A. DHCP

  ---

  Explanation

  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 1053:

  A user submitted a help desk ticket to report that the Wi-Fi connection drops every time the microwave is used. A technician suspects the issue is related to interference. Which of the following should the technician do to provide the BEST long-term solution for the issue?

  A. Change the Wi-Fi operation channel.
  B. Configure the Wi-Fi AP to 5GHz.
  C. Increase the power output of the AP.
  D. Change the SSID to hidden.
  B. Configure the Wi-Fi AP to 5GHz.

  ---

  Explanation

  The issue is related to interference from the microwave, which operates at 2.4GHz, the same frequency as some Wi-Fi channels. To avoid this interference, the technician should configure the Wi-Fi access point (AP) to use a 5GHz band,

  which has more channels and less interference from other devices. Changing the Wi-Fi operation channel may not solve the problem if the microwave interferes with multiple channels. Increasing the power output of the AP may not overcome

  the interference and may cause more interference to other devices. Changing the SSID to hidden does not affect the interference at all, and may make it harder for users to connect to the network.

• Question 1054:

  A printer's output is producing solid black sheets without distinct lettering. A technician adjusted multiple settings, but the issue persists. Which of the following parts is most likely causing this issue?

  A. Imaging drum
  B. Heating element
  C. Fuser assembly
  D. Feed assembly
  A. Imaging drum

  ---

  Explanation

  The correct answer is A. Imaging drum. An imaging drum is a part of a laser printer that transfers the toner to the paper. The imaging drum is coated with a photosensitive material that reacts to light and creates an electrostatic charge. The charge attracts the toner particles from the cartridge and forms an image on the drum. The image is then transferred to the paper by heat and pressure from the fuser assembly. If the imaging drum is defective or damaged, it can cause various printing problems, such as solid black pages, blank pages, streaks, spots, or faded prints. A solid black page can occur when the imaging drum is unable to create a charge pattern on its surface, and instead attracts all the toner from the cartridge. This can happen due to a faulty laser unit, a dirty or scratched drum surface, or a worn-out drum. To fix this issue, the technician should replace the imaging drum with a new one. The imaging drum usually has a limited lifespan and needs to be replaced periodically. The technician should also check the toner cartridge and the fuser assembly for any signs of damage or leakage123

• Question 1055:

  A technician needs to install an NVMe drive in an old computer using a PCIe 4X card. The technician installs Windows on the drive and reboots the computer. An error message appears stating there is no bootable device found. The technician checks the BIOS but cannot select the new drive as a boot device. Which of the following is MOST likely causing the issue?

  A. The boot partition is not set as active.
  B. The BIOS does not have NVMe boot drivers.
  C. The NVMe drive has an MBR partition.
  D. The NVMe drive is out of space.
  B. The BIOS does not have NVMe boot drivers.

• Question 1056:

  Which of the following components houses the MX record?

  A. DNS
  B. VLAN
  C. DHCP
  D. SMTP
  A. DNS

  ---

  Explanation

  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 DNS.

• Question 1057:

  A network engineer recently deployed a new application server in a cloud environment. Which of the following should be implemented to prevent a single point of failure within the system?

  A. Rapid elasticity
  B. RAID
  C. High availability
  D. Shared resources
  C. High availability

  ---

  Explanation

  High availability is a design principle that ensures a system or service can operate continuously without significant downtime or disruption. High availability can be achieved by implementing redundancy, failover, load balancing, and backup strategies. High availability can prevent a single point of failure within the system, which means that if one component fails, another one can take over its function. Rapid elasticity is the ability to scale up or down the resources of a system according to the demand, but it does not prevent a single point of failure. RAID is a method of storing data across multiple disks to provide redundancy and performance, but it does not prevent a single point of failure at the server level. Shared resources are the resources that are pooled and accessed by multiple users or systems, but they do not prevent a single point of failure either.
