CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 111:

  A technician responds to a user who has reported that a laptop is too hot. The technician notices the laptop is not able to sit level on the workspace. What of the following BEST describes the issue with the laptop?

  A. The docking station is improperly installed.

  B. The hard drive is disconnected.

  C. The CPU fan is too powerful.

  D. The battery is damaged.

  Correct Answer: D

  A damaged battery can cause a laptop to overheat and swell, making it unable to sit level on the workspace. A swollen battery can also pose a fire hazard and damage other components of the laptop, such as the motherboard or keyboard. The technician should replace the battery as soon as possible and dispose of it properly according to local regulations.

• Question 112:

  Which of the following is an unsecure remote access protocol?

  A. SSH

  B. HTTPS

  C. SFTP

  D. Telnet

  Correct Answer: D

  Telnet is an unsecure remote access protocol that allows a user to connect to a remote device and execute commands on it12. Telnet does not encrypt the data that is transmitted between the user and the device, which means that anyone who intercepts the network traffic can read the information, including usernames and passwords12. Telnet also does not authenticate the user or the device, which means that anyone can impersonate either party and gain unauthorized access1.

• Question 113:

  A help desk technician receives a ticket stating a printer has jammed several times today. The technician removes the jammed paper and notices the paper supply is low and the paper in the tray is wrinkled. Which of the following MOST likely caused the paper jams?

  A. High latency

  B. Page orientation

  C. Driver mismatch

  D. Multipage misfeed

  Correct Answer: D

  A multipage misfeed is when more than one sheet of paper feeds into the printer at once, causing paper jams or misprints. A multipage misfeed can be caused by low paper supply or wrinkled paper in the tray, as reported by the user in this case. High latency is not related to paper jams, but to network delays or slow performance. Page orientation refers to whether the page is printed in portrait or landscape mode, which does not affect paper jams either. Driver mismatch could cause printing errors or compatibility issues, but not paper jams.

• Question 114:

  Which of the following frequency bands do 802.11b and 802.11g operate in?

  A. 1GHz

  B. 2.4GHz

  C. 5GHz

  D. 6GHz

  Correct Answer: B

  The frequency bands that 802.11b and 802.11g operate in are 2.4GHz bands, which allow for longer range but lower speed than higher frequency bands such as 5GHz or 6GHz bands used by newer standards such as 802.11a/n/ac/ax.

• Question 115:

  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

  Correct Answer: C

  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 116:

  A desktop support technician receives an escalated ticket regarding a computer that displays the following message upon booting up: The amount of system memory has changed. Which of the following components is failing?

  A. GPU

  B. HDD

  C. RAM

  D. CPU

  Correct Answer: C

  The message "The amount of system memory has changed" indicates that there is a problem with the random access memory (RAM) modules in the computer. The RAM may be loose, faulty, or incompatible with the motherboard or other components. The GPU, HDD, and CPU are not directly related to system memory and would not cause this message to appear.

• Question 117:

  A customer brings a phone top a repair shop because it is experiencing extreme slowness and applications are crashing. A technician attempts to install a diagnostic application. but the installation fails. Which of the following should the technician do FIRST to troubleshoot the issue?

  A. Check the storage space.

  B. Inspect the screen for damage.

  C. Install the latest updates.

  D. Recalibrate the digitizer.

  Correct Answer: A

  One of the possible causes of extreme slowness and application crashes on a phone is low or insufficient storage space. This can affect the performance and functionality of the phone, as well as prevent new applications from being installed

  or updated. The technician should check the storage space on the phone and see if there is enough free space available for the diagnostic application and other operations. The technician should also advise the customer to delete or move

  any unnecessary or unused files, apps, or data from the phone to free up some space. Reference:

• Question 118:

  A technician who works in a high-security environment needs to set up a laptop with triple monitors for a new security employee. All USB ports are disabled due to security policies. Which of the following should the technician do to BEST meet the requirements?

  A. Install a splitter cable

  B. Install a discrete graphics card.

  C. use an HDMI switch.

  D. Implement a docking station.

  Correct Answer: D

  This is because a docking station can connect multiple monitors to a laptop without using USB ports, which are disabled in this scenario. A splitter cable would only allow two monitors to be connected, not three. A discrete graphics card would require opening the laptop and installing hardware, which may not be feasible or allowed in a high- security environment. An HDMI switch would only allow one monitor to be active at a time, not all three simultaneously.

• Question 119:

  A technician has noticed that when at company headquarters the laptop connection to the Internet is more responsive than when using the company-provided phone as a hotspot. The technician updated the drivers on the WiFi NIC without resolution and then verified the configuration on the WiFi was correct.

  Which of the following configurations could cause the decreased performance?

  A. The connection if throttled.

  B. There is a low RFID signal.

  C. SSID is not found.

  D. It is out of range.

  Correct Answer: A
