CompTIA 220-1101 Online Questions & Answers

• Question 521:

  A technician is installing multiple plain old telephone service lines for a client.

  Which of the following tools should the technician use to attach the cables? (Select two).

  A. Punchdown tool
  B. Multimeter
  C. Toner probe
  D. Wi-Fi analyzer
  E. Loopback plug
  F. Network tap
  A. Punchdown tool
  C. Toner probe

  ---

  Explanation

  A punchdown tool is essential for connecting telephone wires to patch panels, keystone modules, and punchdown blocks, making it a critical tool for installing plain old telephone service (POTS) lines. A toner probe, on the other hand, is used for tracing and identifying specific wires within a bundle, facilitating the correct attachment of telephone lines to their respective terminals. These tools are fundamental for ensuring proper and efficient installation of POTS lines in a client's environment.

• Question 522:

  A technician needs to determine where a printer is connected on a patch panel. Which of the following is the best tool for the technician to use tolocate the port?

  A. Toner probe
  B. Loopback plug
  C. Cable tester
  D. Wi-Fi analyzer
  A. Toner probe

  ---

  Explanation

  The correct answer is A. Toner probe. A toner probe is an electronic test instrument that can help trace wires and locate the port where a printer is connected on a patch panel. A toner probe consists of two parts: a tone generator and a tone detector. The tone generator sends a signal through the cable, and the tone detector picks up the signal at the other end. By using a toner probe, a technician can identify which port on the patch panel corresponds to the printer cable. A loopback plug is a device that can test the functionality of a network port by sending and receiving signals from the same port. A loopback plug is not useful for locating ports on a patch panel. A cable tester is a device that can verify the integrity and continuity of a cable by checking for open, short, or miswired connections. A cable tester can also measure the length and resistance of a cable. A cable tester is not useful for locating ports on a patch panel. A Wi-Fi analyzer is a software or hardware tool that can monitor and analyze wireless networks by scanning for available channels, signal strength, security settings, and other parameters. A Wi-Fi analyzer is not useful for locating ports on a patch panel.

• Question 524:

  A tier one technician has spent the past thirty minutes troubleshooting an Issue With an end user's network connection After a solution was implemented, the end user rebooted the system, tested the Issue, and confirmed the Issue was resolved.

  Which of the following should the technician do NEXT?

  A. Document the findings, actions, and solution in the company knowledge base
  B. Advise the user to try the solution before contacting the help desk if the Issue happens again
  C. Establish a theory of probable cause
  D. Escalate the Issue to the tier two support team for resolution.
  A. Document the findings, actions, and solution in the company knowledge base

  ---

  Explanation

  According to the Official CompTIA A+ Core 1 Study Guide (220-1101) 1, the correct answer is A. Document the findings, actions, and solution in the company knowledge base. The explanation is that after resolving an issue, a technician should always document what was done and how it was fixed. This helps to create a record of the problem and its solution for future reference and also to share knowledge with other technicians. https://www.comptia.org/training/books/acore-1-220-1101-study-guide By documenting the findings, actions, and solution in the company knowledge base, it will help to ensure that if the Issue happens again, the technician or a different technician will be able to quickly and easily find the solution and resolve the Issue. Additionally, it is important to document the solution so that the same Issue does not need to be troubleshot multiple times in the future.

• Question 525:

  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.
  D. The HDD has no free space.

  ---

  Explanation

  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 526:

  Ann, a user, reports that after setting up a new WAP in her kitchen she is experiencing intermittent connectivity issues. Which of the following should a technician check FIRST?

  A. Correct WiFi password
  B. Frequency
  C. Antenna power level
  D. SSID
  D. SSID

  Explanation

• Question 527:

  After a corporate office upgraded its Ethernet wiring, a number of users are unable to access the internet. A technician establishes a theory for troubleshooting the issue and tests it, but the theory is incorrect. Which of the following should the technician do next?

  A. Document the findings.
  B. Gather additional details.
  C. Escalate the problem.
  D. Identify user changes.
  B. Gather additional details.

  ---

  Explanation

  The correct answer is

  B. Gather additional details.

  According to the CompTIA troubleshooting process for the A+ certification exams1, the technician should gather additional details after testing a theory that is incorrect. This step helps to identify the problem more accurately and establish a new theory of probable cause. The other options are not appropriate for this stage of the troubleshooting process. Documenting the findings, escalating the problem, and identifying user changes are steps that should be done later in the process, after determining the cause and implementing a solution1.

• Question 528:

  A user connects a smartphone to a laptop. Which of the following types of networks has the user created?

  A. PAN
  B. MAN
  C. WLAN
  D. LAN
  A. PAN

  ---

  Explanation

  When a user connects a smartphone to a laptop, they create a Personal Area Network (PAN). A PAN is a type of network used for communication between devices in close proximity to each other, typically within a range of a few meters or

  less. This type of network is commonly used for wireless communication between personal devices, such as connecting a smartphone to a laptop for file sharing or internet access.

• Question 529:

  A startup is looking to immediately expand its data center but does not have the personnel or space to manage everything internally. The organization has multiple small offices and remote users with large computational and storage-solution requirements. Funding is not an issue for the company. Which of the following can BEST accomplish the company's goals?

  A. SaaS
  B. laaS
  C. ISP
  D. SON
  B. laaS

  ---

  Explanation

  IaaS is a cloud computing model where a third-party provider hosts infrastructure components such as servers, storage, and networking on behalf of customers. This allows the startup to immediately expand its data center without the need for additional personnel or space to manage everything internally. Additionally, IaaS allows remote users to easily access the required computational and storage resources from multiple small offices. Infrastructure as a Service (laaS) can provide the startup with the necessary computational and storage solutions without the need for internal management. laaS allows organizations to rent computing resources from a third-party provider instead of owning and maintaining them in-house.
