CompTIA CompTIA Certifications 220-1101 Questions & Answers

• Question 421:

  A technician is upgrading a faulty motherboard that was ordered by an end user for an old, high-end desktop computer. However, the technician is unable to install the CPU into the socket. Upon closer inspection, the technician notices the pins on the CPU do not line up with the socket.

  Which of the following would be the best course of action for the technician to take NEXT?

  A. Try to set as many pins as possible.

  B. Install an adaptor to create a universal socket.

  C. Verify the socket type and manufacturer.

  D. Find a compatible motherboard for the CPU.

  Correct Answer: C

  In this situation, the best course of action for the technician to take NEXT would be C. Verify the socket type and manufacturer. If the pins on the CPU do not line up with the socket on the motherboard, it is likely that there is a compatibility issue between the two components. The technician should verify that the socket type and manufacturer of the motherboard match those of the CPU to ensure that they are compatible.

• Question 422:

  A user reports that printed receipts have black smudges over the entire image. The text is still present but is very dark and sometimes illegible. Which of the following are the MOST likely cause and solution for the printer issue?

  A. The ribbon is jammed and is rubbing on the paper. Clear the bad ribbon and feed it through properly.

  B. The printhead is too hot. Adjust the temperature down and retry printing.

  C. The printer is loaded with the wrong type of paper. Replace the receipt paper with carbon paper.

  D. The blue ink cartridge was loaded with black ink. Put in the correct ink and clean the printhead.

  Correct Answer: B

  Receipts are printed via a thermal printer. Thermal printers work by heating a paper in specified areas in order to create an image. The specific component that does this is a thermal printhead. Since the image appears to have black smudges and is too dark, we know the thermal printhead is too hot since the capability of precise heating has diminished

• Question 423:

  A user's mobile phone gets really hot to the touch and does not retain a charge. The user also reports that the phone is very slow, especially while charging. Which of the following is MOST likely causing these symptoms?

  A. Broken charging port

  B. Digitizer failure

  C. CPU overheating

  D. Defective battery

  Correct Answer: D

  A defective battery is the most likely cause of a mobile phone that gets really hot to the touch, does not retain a charge, and is slow while charging. A defective battery can cause the phone to overheat and may also cause performance issues.

• Question 424:

  Which of the following describes the operational difference between hubs and switches when transmitting data to a specific computer inside the network?

  A. Switches only send data to the specific computer, while hubs send data to all computers inside the network.

  B. Switches compress data while hubs send uncompressed data

  C. Switches receive data and route it to all computers inside the network while hubs receive data and do not route

  D. Switches scramble data, while hubs send data in the original form.

  Correct Answer: A

  Switches only send data to the specific computer, while hubs send data to all computers inside the network. References: CompTIA A+ Certification uide, Exam 220-1001, Page 323

• Question 425:

  A user submitted a support ticket that states all of the printouts from a laser printer appear to have double images imposed on them. A review of past printer support tickets shows that maintenance kit has not been installed in more than a year. Which of the following printer consumables is MOST likely causing the issue?

  A. Separation pad

  B. Transfer roller

  C. Ink cartridge

  D. Fuser

• Question 426:

  A user reports issues with a smartphone after dropping it. The icons on the screen all look normal, but when the user touches the email icon, for example, nothing happens. Which of the following is MOST likely the cause?

  A. Digitizer issues

  B. Overheating

  C. Broken screen

  D. Malware

  Correct Answer: A

  Dropping a smartphone can damage the digitizer, which is the component responsible for sensing touch input. This can cause issues with tapping and swiping on the screen, as well as other touchscreen-related issues.

• Question 427:

  A technician is receiving reports that the entire office sporadically loses network connectivity thrc cable mediums would be the MOST cost effective without sacrificing system performance?

  A. Coaxial

  B. Shielded Cat 6

  C. Plenum Cat 5e

  D. Multimode fiber

  Correct Answer: B

  Electromagnetic interference (EMI) is unwanted noise or interference in an electrical path or circuit caused by an outside source. Hence shielded Cat 6 is better If a technician determines that the root cause of sporadic network connectivity issues is EMI, the most cost-effective cable medium that can be used without sacrificing system performance is shielded Cat 6 cable. Shielded cables protect against electromagnetic interference (EMI) and radio frequency interference (RFI).

• Question 428:

  Upon booting a workstation, a technician hears a distinct clicking sound after power is applied to the motherboard. Which of the following would MOST likely be the cause?

  A. RAID

  B. SSD

  C. S.M.A.R.T

  D. HDD

  Correct Answer: D

  The clicking sound is the sound of a damaged disk in the HDD A clicking sound from a hard disk drive typically indicates a mechanical failure, such as the read/write head hitting a physical obstruction or a problem with the disk motor. This can cause the drive to fail to initialize or not be recognized by the system during booting.

• Question 429:

  Which of the following utilizes TCP ports 20/21 and transfers data in cleartext?

  A. SNMP

  B. SSH

  C. FTP

  D. Telnet

  Correct Answer: C

  FTP (File Transfer Protocol) uses TCP ports 20/21 and transfers data in cleartext, which means the data is not encrypted and can be read by anyone who intercepts it. This makes FTP insecure for transferring sensitive information. SSH (Secure Shell), on the other hand, uses port 22 and encrypts data, making it more secure. SNMP (Simple Network Management Protocol) uses ports 161/162 and is used to monitor network devices. Telnet uses port 23 and transfers data in cleartext, making it insecure.

• Question 430:

  A technician needs to add storage to a workstation. The workstation does not have room to add any internal storage, so the technician plans to add an external storage device. Which of the following connection types should the technician MOST likely use?

  A. SCSI

  B. eSATA

  C. PCIe

  D. NVMe

  Correct Answer: B

  eSATA is the best choice for adding external storage as it offers a fast transfer rate and is specifically designed for external storage devices. SCSI is an older interface that is rarely used today, PCIe is typically used to add expansion cards to a computer, and NVMe is a newer interface for high-speed solid-state storage, but it is typically used for internal storage devices.
