CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 81:

  A user's laptop is experiencing severe slowdowns when operating process-intensive tasks. Which of the following memory upgrades is compatible with a laptop?

  A. DIMM

  B. ECC RAM

  C. Virtual RAM D. SODIMM

  Correct Answer: D

  SODIMM stands for Small Outline Dual In-line Memory Module and is a type of memory module that is compatible with laptops and other small devices. SODIMMs are smaller and thinner than DIMMs (Dual In-line Memory Modules), which are typically used for desktop PCs and servers. Upgrading or adding SODIMMs can increase the amount of RAM available for a laptop, which can improve its performance and speed when running process-intensive tasks.

• Question 82:

  A customer reports that, after a technician replaced a laptop screen, the laptop is only able to connect to a Wi-Fi network it is positioned very close to a wireless access point

  Which of the following should the technician verify FIRST?

  A. The internal antennas are connected.

  B. The device has the latest OS updates.

  C. The wireless device drivers are the latest version.

  D. Airplane mode is disabled.

  E. The battery is charging.

  Correct Answer: A

  The internal antennas are the components that allow the laptop to receive and transmit wireless signals. If the internal antennas are not connected properly, the laptop may have a weak or no Wi-Fi signal. The technician should verify that the internal antennas are connected to the wireless card and routed correctly inside the laptop case. The internal antennas may have been disconnected or damaged during the screen replacement. The device having the latest OS updates, the wireless device drivers being the latest version, airplane mode being disabled, and the battery being charging are not related to the issue, as they do not affect the physical connection of the internal antennas.

• Question 83:

  An IT technician is inspecting the internal components of a desktop computer to assess a suspected power issue with the motherboard. Which of the following connectors should the IT technician inspect further?

  A. RJ45

  B. Straight tip

  C. DB9

  D. Molex

  Correct Answer: D

  The connector that the IT technician should inspect further is Molex. The Molex connector is used to provide power to the motherboard and other components in the computer. If there is a suspected power issue with the motherboard, the IT technician should inspect the Molex connector to ensure that it is properly connected and providing power to the motherboard1

• Question 84:

  Using the output below:

  

  Which of the following is the default gateway?

  A. 172.25.1.252

  B. 172.25.1.39

  C. 172.25.1.4

  D. 255.255.255.0

  Correct Answer: A

  The default gateway is the IP address of the router or device that connects a network to another network or the internet. In the output below, the default gateway is 172.25.1.252, as shown in the line "Default Gateway . . . . . . . . . : 172.25.1.252". The other IP addresses are not default gateways, but either local IP addresses (172.25.1.39 and 172.25.1.4) or subnet masks (255.255.255.0).

• Question 85:

  Following a scheduled power outage, users report they cannot access the local intranet. A technician is able to ping the IP address of the server that is hosting the website. Which of the following serves is MOST likely offline?

  A. Web

  B. DNS

  C. File

  D. DHCP

  Correct Answer: B

  DNS stands for Domain Name System and is a service that translates domain names (such as www.example.com) into IP addresses (such as 192.168.1.100) that computers can use to communicate over a network. If the DNS server is

  offline, users may not be able to access websites or other network resources by using their domain names, even if they are online and reachable by their IP addresses. The technician should check if the DNS server is running and configured

  correctly, or use an alternative DNS server if possible.

• Question 86:

  A technician needs to configure a printer for network communications

  Which of the following must the technician configure? (Select THREE).

  A. PCL

  B. Dots per Inch

  C. Gateway

  D. Subnet mask

  E. MAC address

  F. IMEI

  G. IP address

  H. Drivers

  Correct Answer: CDG

  To configure a printer for network communications, the technician must configure its network settings, such as gateway, subnet mask, and IP address. The gateway is the IP address of the router or device that connects the printer to other networks or the internet. The subnet mask is a value that defines which part of the IP address identifies the network and which part identifies the host or device on that network. The IP address is a unique identifier that allows the printer to communicate with other devices.

• Question 87:

  A technician receives an alert indicating all VMs are down. After some troubleshooting, the technician discovers the network is out of space. To resolve the issue, the technician decides to add more space. Which of the following network types will the technician be working with?

  A. SCSI

  B. NAC

  C. SAN

  D. WISP

  Correct Answer: C

  A storage area network (SAN) is the type of network that the technician will be working with when adding more space to resolve the issue of all VMs being down due to the network being out of space. A SAN is a network that provides access to consolidated and block-level data storage, which can be used for virtualization and backup purposes. SCSI is a type of interface that connects devices such as hard drives and optical drives to a computer. NAC is a type of security solution that controls access to a network based on policies and device compliance. WISP is a type of internet service provider that delivers wireless broadband access over long distances.

• Question 88:

  A user's desktop computer slows down after a few minutes of use, and the fans alternate between silent and very loud. Which of the following is MOST likely failing, therefore causing these symptoms?

  A. CPU fan

  B. Memory

  C. Power supply

  D. Hard drive

  Correct Answer: A

  A CPU fan is a component that cools down the CPU, which is the main processor of the computer. If the CPU fan is failing, it can cause the computer to slow down and the fans to alternate between silent and very loud12. This is because the CPU fan cannot maintain a consistent speed and airflow to keep the CPU at a safe temperature. When the CPU gets too hot, it throttles its performance to avoid overheating, which results in a slower computer. The other fans in the computer also try to compensate for the lack of cooling from the CPU fan by spinning faster and louder2.

• Question 89:

  A help desk technician plugged in a user's new computer to a network port After a few minutes the computer showed an APIPA address. Which of the following is the MOST likely reason this happened?

  A. The WLAN is disabling the NIC card.

  B. The network cable is not attached.

  C. The PC is unable to contact a DHCP server

  D. The DHCP server is using addresses in the range of 169.254.254.1.

  Correct Answer: C

  The most likely reason for a computer showing an APIPA address after being plugged into a network port is that the PC is unable to contact a DHCP server1. Automatic Private IP Addressing (APIPA) is a DHCP fail-safe that protects a computer system from failure. It invokes a standby mechanism for local Internet Protocol version 4 (IPv4) networks supported by Microsoft Windows. With APIPA, DHCP clients can obtain IP addresses even when DHCP servers are not functional1. The other options are less likely to be the cause of the issue1.

• Question 90:

  Every time a user sends a print job, the user must walk over to the printer and press OK before the job will print. The same issue is occurring for multiple users. Which of the following is the MOST likely cause of the issue?

  A. The wrong network printer queue is being used.

  B. The network printer is on the wrong VLAN.

  C. A The default paper type has been changed.

  D. The print server has outdated print drivers.

  Correct Answer: C

  The message prompting to press "OK" indicates that the printer is waiting for a user input. This suggests that there is some issue with the printer settings, and the most probable cause is that the default paper type has been changed, and the printer needs the user to confirm the paper type before proceeding with the print job. This is a common issue that can occur when the default paper type is not set correctly or has been changed without the user's knowledge.
