A company needs to develop a disaster recovery solution based on virtual machines.
Which of the following service models is the most suitable?

  1. Infrastructure as a service
  2. Security as a service
  3. Platform as a service
  4. Software as a service

Answer(s): A

Explanation:

IaaS provides virtualized compute resources, such as virtual machines, storage, and networking, that can be spun up on demand in a disaster recovery scenario, giving full control over VM configurations and rapid failover capabilities.



A technician is connecting a hands-free car system via Bluetooth.
Which of the following is a security feature that should be used for this task?

  1. BitLocker
  2. Biometrics
  3. TPM
  4. PIN code

Answer(s): D

Explanation:

Bluetooth pairing uses a PIN (or passkey) to authenticate devices and prevent unauthorized connections.
When you pair a hands-free car system, you enter a PIN code on both the car's system and the phone to establish a trusted link.



A technician is troubleshooting a laptop's connectivity via its USB-C port to a projector. The same laptop works well when it is connected to a USB-C docking station. The projector is configured as expected, and the USB-C cable was tested on a charging port.
Which of the following could be the issue?

  1. The USB-C cable requires a power injector
  2. The USB-C cable is not compatible with Thunderbolt technology.
  3. The USB-C cable needs an adapter to work with the laptop.
  4. The USB-C cable does not support enough power.

Answer(s): B

Explanation:

Not all USB-C cables support video output (DisplayPort Alt Mode) or Thunderbolt, even though they carry power. A charge-only USB-C cable will work for charging tests but won't pass the video signal to the projector.
You need a USB-C cable rated for Thunderbolt or DisplayPort Alt Mode to transmit the display data directly.



A high-end workstation with a RAID 5 array is exhibiting slow data access speeds and occasional errors when retrieving files. The technician investigates further and notices one of the hard drives in the RAID array has an amber light.
Which of the following steps should the technician take to troubleshoot and resolve the issues?

  1. Review network issues that might be causing slow speeds.
  2. Upgrade all RAID drives to higher capacity models to increase data access speeds.
  3. Replace the failing drive, and then allow the RAID controller to rebuild the array.
  4. Reformat all drives in the RAID array to clear any software issues that might be causing the errors.

Answer(s): C

Explanation:

An amber light indicates a degraded or failing member of the RAID 5 array. Swapping in a new drive and letting the controller rebuild restores full redundancy and performance without risking data loss.



Which of the following provides electricity to devices through network cables?

  1. Edge router
  2. PoE switch
  3. Access point
  4. Patch panel

Answer(s): B

Explanation:

A Power over Ethernet (PoE) switch delivers both data and DC power over the same Ethernet cable, enabling network devices like IP cameras and access points to receive electricity without separate power adapters.
