CompTIA 220-1101 Online Questions & Answers

• Question 941:

  A technician is setting up network printers in a new office building. The company wants all of the printers to be configured the same way for consistency. Some of the printers do not have an RJ45 port to connect to the network.

  Which of the following does the technician need to enable so all of the printers can be connected to the network?

  A. Wireless
  B. Authentication
  C. PostScript
  D. USB
  A. Wireless

  ---

  Explanation

  To connect printers without an RJ45 port to the network, the technician needs to enable wireless connectivity. By configuring the printers to connect to the network wirelessly, the company can achieve the desired consistency in printer configuration across the office. This approach allows printers without built-in wired network capabilities to be part of the network, facilitating shared access and remote printing functionalities.

• Question 946:

  A user reports a monitor, keyboard, mouse. and headset are no longer functioning. The user has restarted the laptop and tested an alternative headset and monitor, but the issue persists. The technician notices the user has a printer. USB-C hub, and AC adapter plugged into the laptop. Which of the following should the technician do to MOST likely resolve the issue?

  A. Verify the AC adaptor voltage.
  B. Repair the operating system.
  C. Replace the user's USB-C hub.
  D. Reinstall the drivers for affected devices.
  E. Make sure the printer is not drawing too much power.
  C. Replace the user's USB-C hub.

  ---

  Explanation

  The most likely cause of the issue is that the user's USB-C hub is faulty or incompatible with the laptop. The USB-C hub is a device that allows the user to connect multiple peripherals to the laptop using a single USB-C port. If the hub is not working properly, it may prevent the monitor, keyboard, mouse, and headset from functioning. The technician should replace the user's USB-C hub with a new one that is compatible with the laptop and test the peripherals again. Verifying the AC adapter voltage will not help with the issue, as the AC adapter is used to power the laptop, not the peripherals. Repairing the operating system will not help either, as the issue is not related to software. Reinstalling the drivers for affected devices may not help, as the issue may be caused by the hub, not the devices. Making sure the printer is not drawing too much power is irrelevant, as the printer is not connected to the hub or affecting the other peripherals.

• Question 947:

  A user's smartphone repeatedly loses the connection to a home Wi-Fi network. The user has already tried restarting the smartphone, rebooting the router, and resetting the smartphone's Wi-Fi network settings. Which of the following should the user do next to resolve the issue?

  A. Replace the router.
  B. Update the smartphone's OS.
  C. Switch the router to 5GHz.

• Question 948:

  A technician is monitoring all outbound traffic in a SOHO. Which of the following is the MOST cost-effective solution to monitor the traffic?

  A. Spectrum analyzer
  B. Network tap
  C. Lookback plug
  D. Toner probe
  B. Network tap

  ---

  Explanation

  A network tap is used to intercept the signals passing over a cable and send them to a packet or protocol analyzer. Taps are either powered or unpowered:

• Question 949:

  A user returns to work after a two-week vacation and cannot connect to an internal server. The remote drives were working the last time the user accessed them. Which of the following steps should the technician take next?

  A. Conduct external research on the server software vendor's website.
  B. Reference the server vendor's documentation for guidance.
  C. Confirm a theory and determine the next steps to resolve the issue.
  D. Determine if any infrastructure changes have been made.
  D. Determine if any infrastructure changes have been made.

  ---

  Explanation

  The first step in troubleshooting any network connectivity issue is to identify the scope and source of the problem. The technician should check if any infrastructure changes have been made during the user's absence, such as updates, patches, configuration changes, or hardware replacements. These changes could affect the network settings, firewall rules, permissions, or compatibility of the user's device or the server. The technician should also verify if other users or devices can access the server or if the problem is isolated to the user's device. By determining if any infrastructure changes have been made, the technician can narrow down the possible causes and formulate a theory to test.

• Question 950:

  While reviewing options in the BIOS/UEFI settings page to fix a laptop issue, a support technician notices an option to clear existing TPM keys.

  Which of the following would most likely happen if the TPM is cleared?

  A. Encrypted hard drives would probably not be accessible.
  B. All security certificates would need to be reinstalled from trusted roots.
  C. The device would need to be reenrolled in the MDM platform
  D. The laptop would need to be registered to the domain as a new client.
  A. Encrypted hard drives would probably not be accessible.

  ---

  Explanation

  The Trusted Platform Module (TPM) is a hardware-based security feature used to store cryptographic keys, such as those used for encryption, authentication, or device identification. It plays a critical role in ensuring secure operations for encrypted drives, BitLocker, and secure boot processes. Clearing TPM keys involves wiping all stored cryptographic data, which can lead to several consequences depending on what the TPM was being used for. Let's break it down:

  Correct Answer:

  Option A: Encrypted hard drives would probably not be accessible. Encrypted hard drives, such as those secured with BitLocker encryption, rely on the cryptographic keys stored in the TPM to unlock data. Clearing the TPM will erase these keys, making it impossible for the encrypted drive to decrypt its contents unless a recovery key (separate from the TPM) is available. Without this recovery key, the data will likely become inaccessible. CompTIA A+ Core 1 Exam Objective

  This falls under Objective 3.5, which covers understanding BIOS/UEFI configurations, TPM functions, and securing devices.

  Why the Other Options Are Incorrect:

  Option B: All security certificates would need to be reinstalled from trusted roots.

  Option C: The device would need to be reenrolled in the MDM platform.

  Option D: The laptop would need to be registered to the domain as a new client.

  Practical Example:

  A user enables BitLocker on their laptop, which relies on the TPM to store the encryption key. Later, if they clear the TPM via BIOS/UEFI without saving the BitLocker recovery key separately, they will not be able to unlock the hard drive, leading to data loss unless the recovery key is available. This is a common issue when technicians or users inadvertently clear the TPM without understanding its role in encryption.

  Objective 3.5: Given a scenario, install and configure laptop hardware and components, including UEFI/BIOS security settings (TPM, secure boot, etc.). This question tests understanding of TPM functionality, encryption technologies, and secure device configurations.
