A technician receives several error alerts on a server after an unexpected reboot. A message states that one or more disks are in a degraded state. When the technician advances to the next error message, it indicates the OS is missing.

Which of the following are the MOST likely causes of these errors? (Choose two.)

Missing drives in the OS
Missing drives in the OS
RAID failure
RAID failure
Bootable device not found
Bootable device not found
Data loss
Data loss
Controller failure
Controller failure
CMOS corruption
CMOS corruption
TPM malfunction
TPM malfunction
Suggested answer: B, C

Explanation:

The message stating that one or more disks are in a degraded state is a clear indication of a RAID failure. RAID stands for Redundant Array of Independent Disks, and it is a technology used to provide fault tolerance and improve performance by combining multiple hard drives into a single logical unit.The message indicating that the OS is missing is most likely caused by a bootable device not found.This means that the server is unable to boot from the designated boot device, which could be the hard drive, a CD/DVD drive, or a USB flash drive. This could be caused by a faulty boot device, a loose cable, or a misconfiguration in the BIOS or UEFI settings.

A technician is receiving reports that the entire office sporadically loses network connectivity throughout the day. The technician determines the root cause to be EMI. Which of the following cable mediums would be the MOST cost effective without sacrificing system performance?

Coaxial
Coaxial
Shielded Cat 6
Shielded Cat 6
Plenum Cat 5e
Plenum Cat 5e
Multimode fiber
Multimode fiber
Suggested answer: B

Explanation:

In this situation, the MOST cost-effective cable medium that would not sacrifice system performance would be B. Shielded Cat 6. Electromagnetic interference (EMI) can disrupt network connectivity by interfering with the signals transmitted over network cables. Shielded Cat 6 cables are designed to provide protection against EMI by incorporating a layer of shielding material around the cable’s conductors. This shielding helps to prevent EMI from interfering with the signals transmitted over the cable.

To have dedicated hardware for a single system
To have dedicated hardware for a single system
Suggested answer: A

Explanation:

The main reason to use a virtual machine as a sandbox is to test new software in a safe environment without risking the integrity of the host operating system. Using a virtual machine enables the testing of software and allows for the isolation of the software from the host system. Reference: CompTIA A+ Certification Study Guide, Tenth Edition, pg. 409

While implementing a non-carrier-grade wireless backhaul, a technician notices the current channel selection is externally polluted with various RF signals. Upon performing a spectral analysis, the technician discovers a channel containing almost no RF pollution. Unfortunately, the technician is unable to select that channel. Which of the following is the MOST likely reason for this issue?

The channel is reserved for licensed band use.
The channel is reserved for licensed band use.
The channel selection is defective, contact the manufacturer.
The channel selection is defective, contact the manufacturer.
The channel must be unblocked by the vendor.
The channel must be unblocked by the vendor.
The device requires a firmware update to unlock the channel.
The device requires a firmware update to unlock the channel.
Suggested answer: A

Explanation:

The 2. band is subdivided into up to 14 channels, spaced at 5 MHz intervals from 2412 MHz up to 2484 MHz. Wi-Fi requires bandwidth of approximately 20 MHz, not 5 MHz. Consequently, a site designer needs to choose the channels that do not overlap. On a WLAN where only the first 11 channels are available, channels 1, 6, and 11 can be selected as non-overlapping. Note: In the Americas, regulations permit the use of channels 1-11 only, while in Europe, channels 1-13 are permitted. In Japan, all 14 channels are permitted
