• Question 202:

  A technician needs to run cable for a new office through a drop ceiling.

  Which of the following cable types should the technician run?

  A. BNC
  B. Fiber-optic
  C. Coaxial
  D. Plenum
  D. Plenum

  ---

  Explanation

  When running network cable through a drop ceiling, the space above the ceiling is often used as part of the building's air circulation system (an air return). In these plenum spaces, building and fire safety standards require cable jackets that produce less smoke and fewer toxic fumes if exposed to heat or fire. Plenum-rated cable is manufactured with a special fire-resistant jacket designed for these environments, making it the correct choice for safe and compliant cabling runs in ceilings and other air-handling areas. This is a key CompTIA A+ Core 1 concept: selecting the proper cable rating based on where the cable is installed to reduce safety hazards and meet code requirements.

  The other options do not match the requirement. BNC is a connector type commonly associated with older coaxial networking and certain video applications, not a cable rating for ceiling installations. Coaxial is a cable type used for cable internet and some video signals, but the question is specifically about the required type for a drop ceiling environment, which is about the jacket rating. Fiber-optic is used for high-speed backbone links and long distances, but the question is focused on safety/installation requirements in a ceiling space.

  Therefore, plenum is the best answer.

• Question 203:

  A user reports that a laptop correctly connects to the internet when docked at the office but is unable to access the internet when at home.

  Which of the following should the technician do first?

  A. Contact the user's home ISP
  B. Give the user a dock to use at home.
  C. Disable network security settings.
  D. Enable the wireless adapter.
  D. Enable the wireless adapter.

  ---

  Explanation

  A wireless adapter is a device that allows a laptop to connect to a wireless network, such as a home Wi-Fi router. A wireless adapter can be either internal or external, and it can be enabled or disabled by the user or the operating system. If the wireless adapter is disabled, the laptop will not be able to access the internet when it is not connected to a wired network, such as the office dock. The technician should do the following steps to enable the wireless adapter: Check the physical switch or button on the laptop that controls the wireless adapter. Some laptops have a switch or button on the side, front, or keyboard that can turn on or off the wireless adapter. Make sure the switch or button is in the on position.

  Check the software settings for the wireless adapter. In Windows 10, you can do this by clicking on the network icon in the system tray, and then clicking on the Wi-Fi icon. Make sure the Wi-Fi is turned on. You can also go to Settings > Network & Internet > Wi-Fi and make sure the Wi-Fi is turned on. Check the device manager for the wireless adapter. In Windows 10, you can do this by right-clicking on the Start menu and selecting Device Manager. Expand the Network adapters category and look for your wireless adapter. Make sure it is enabled and has no errors. You can right-click on it and select Enable device or Update driver if needed. If none of these steps work, there may be a hardware or software problem with the wireless adapter that requires further troubleshooting or replacement.

• Question 204:

  A technician is migrating an application server to another server.

  Which of the following DNS records should the technician create to ensure seamless connectivity?

  A. TXT
  B. SPF
  C. DKIM
  D. CNAME
  D. CNAME

  ---

  Explanation

  To ensure seamless connectivity during (and after) migrating an application server, the best DNS approach in CompTIA A+ Core 1 (220-1201) terms is to use a CNAME (Canonical Name) record, which creates an alias from one hostname to another. Instead of users connecting directly to a server's changing hostname, they connect to a consistent service name (for example, app.company.com). That name can be configured as a CNAME pointing to the current host (such as server1.company.com). When the application is moved to a new server, the technician updates what the alias ultimately resolves to (or updates the target host's A/AAAA record), and clients continue using the same familiar application URL/ name-minimizing disruption and avoiding the need to reconfigure endpoints across devices.

  The other record types are not designed for this purpose. TXT records store text-based information (often verification or policy data). SPF and DKIM are email authentication-related mechanisms (typically implemented via TXT records) used to validate authorized mail senders and message integrity-not application server migration. Because the goal is maintaining a stable name for a service while the underlying host changes, CNAME is the correct record type.

• Question 205:

  Several users report that a projector routinely turns off in the middle of meetings and does not tum back on immediately. Users have to wait several minutes before the projector will turn back on. When the projector is on, the picture is clear and bright.

  Which of the following is the most likely reason the projector is turning off?

  A. The video cable connecting the video source to the projector is failing.
  B. The bulb in the projector is failing.
  C. The projector is overheating and needs to be cleaned.
  D. The outlet that the projector is plugged into is faulty.
  C. The projector is overheating and needs to be cleaned.

  ---

  Explanation

  The projector is overheating and needs to be cleaned. A common cause of projector shutdown is overheating, which can be triggered by dust accumulation, blocked vents, or faulty fans. The projector has a thermal protection circuit that turns it off when the temperature reaches a certain level, and it will not turn back on until it cools down. To prevent this issue, the projector needs to be cleaned regularly and placed in a well-ventilated area. The video cable, the bulb, and the outlet are not likely to cause the projector to turn off intermittently.

• Question 206:

  A salesperson is unable to reach the internet from a home office PC. A support technician wants to verify the router is receiving a valid public IP address.

  Which of the following is a valid public IP address in this scenario?

  A. 10.254.128.11
  B. 66.157.195.20
  C. 172.16.0.30
  D. 192.168 1.50
  B. 66.157.195.20

  ---

  Explanation

  A valid public IP address must fall outside the private IP address ranges:

  10.0.0.0 to 10.255.255.255

  172.16.0.0 to 172.31.255.255

  192.168.0.0 to 192.168.255.255

  66.157.195.20 is outside these ranges, making it a public IP address.

  Why Not A, C, D: These IPs fall within private IP address ranges.

• Question 207:

  A customer experiences a power outage at their data center. After the outage, one server with three hard drives in RAID 5 does not come back online.

  When a technician connects to the server, they receive a message stating that Drive 3 has failed.

  Which of the following steps should the technician take next to minimize the risk of data loss?

  A. Replace the defective drive and trigger an array rebuild.
  B. Acknowledge the drive error and allow the system to start normally.
  C. Upgrade the firmware on the drives.
  D. Perform a full drive restore from the most recent backup.
  A. Replace the defective drive and trigger an array rebuild.

  ---

  Explanation

  RAID 5 provides fault tolerance by distributing parity information across all drives, allowing the array to continue operating if one drive fails. In a three-drive RAID 5 set, a single disk failure puts the array into a degraded state where it can still function, but it is at higher risk because losing a second drive before recovery would cause data loss. Since the system reports Drive 3 has failed after a power outage, the best next step to minimize risk is to replace the failed drive immediately and start the rebuild. Rebuilding regenerates the missing data blocks onto the new drive using parity, returning the array to a protected state.

  Option B leaves the array degraded and increases exposure to a second failure.

  Option C (firmware upgrade) is not a first response in an active failure scenario and can introduce additional risk or downtime.

  Option D (restore from backup) is typically used when the array is unrecoverable or multiple drives fail; it is more disruptive and unnecessary when RAID 5 can recover from a single-disk failure. Therefore, replacing the defective drive and triggering an array rebuild is the correct next step.

• Question 208:

  Which of the following is an advantage of using a hybrid cloud instead of a public cloud?

  A. Ability to reduce management overhead
  B. Ability to use cross-platform virtualization
  C. Ability to meet data residency requirements
  D. Ability to leverage IaaS and PaaS
  C. Ability to meet data residency requirements

  ---

  Explanation

  A hybrid cloud combines on-premises infrastructure with public cloud services. One significant advantage is that it allows organizations to keep sensitive data in a private environment to meet regulatory or data residency requirements, while still utilizing the scalability and cost-efficiency of the public cloud for other workloads. This ensures compliance with legal mandates about data location.
