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 cable mediums would be the MOST cost effective without sacrificing system performance?
A. Coaxial
B. Shielded Cat 6
C. Plenum Cat 5e
D. Multimode fiber
Explanation: Electromagnetic interference (EMI) is unwanted noise or interference in an electrical path or circuit caused by an outside source. Hence shielded Cat 6 is better If a technician determines that the root cause of sporadic network connectivity issues is EMI, the most cost-effective cable medium that can be used without sacrificing system performance is shielded Cat 6 cable. Shielded cables protect against electromagnetic interference (EMI) and radio frequency interference (RFI).

A technician just finished building a new PC and needs to install a firmware update for the system board UEFI. The technician is experiencing issues while accessing the USB key. Which of the following features should the technician most likely disable in order to complete this task?
A. TPM security
B. USB 3.0 support
C. PXE boot capability
D. Secure Boot
Explanation: When experiencing issues accessing a USB key for a firmware update, particularly in relation to system board UEFI updates, the Secure Boot feature should be considered. Secure Boot is a security standard designed to ensure that a computer boots using only software that is trusted by the PC manufacturer. If Secure Boot is enabled, it might prevent the system from recognizing or booting from the USB key if the firmware update or the USB drive is not recognized as a trusted source. Disabling Secure Boot temporarily can allow the firmware update to proceed.

A. Replacing the power supply
B. Replacing the UPS
C. Changing the CMOS battery
D. Reseating the RAM

Reseating the RAM is the best course of action to remediate the issue of three consecutive
beeps during boot, as it may indicate a RAM failure or loose connection. By reseating the
RAM, the technician can ensure that the connection is secure and the computer should
boot normally.

A user reports that, despite manually changing the date and time on a computer, the changes always revert after the computer is turned off for a period of time. Which of the following should the technician consider first?
A. OS updates
B. CMOS battery
C. NTP server
D. RAM
Explanation:
The CMOS battery powers the real-time clock (RTC) on the motherboard, which maintains the date and time when the computer is turned off. If the battery fails, the system will lose date and time settings, reverting to defaults on restart.
✑ Why Not A (OS updates): While OS updates can sometimes cause time issues,
they don’t typically affect changes persisting after shutdown.
✑ Why Not C (NTP server): An incorrect NTP server setting would cause the system to synchronize incorrectly, but this issue relates to time resetting during power-off.
✑ Why Not D (RAM): RAM is volatile memory and unrelated to storing persistent time settings.

A company needs to secure remote user data with minimal interaction. Which of the following should the company do?
A. Configure self-encryptinghardware.
B. Update firewall rule sets.
C. Enable BIOS passwords.
D. Remove physical ROM drives.
Explanation: Self-encrypting hardware, such as self-encrypting drives (SEDs), provides an effective solution for securing data with minimal user interaction. SEDs automatically encrypt all data stored on the drive without requiring any special software or user action, ensuring that data remains protected even if the drive is removed from the device. This feature is particularly beneficial for remote users who may not consistently follow manual encryption procedures, offering a seamless and user-transparent method to secure sensitive data.
Which of the following describes metered utilization of cloud resources?
A. Resources provisioned instantly
B. Payments made only for resources that are used
C. Resources pooled to increase computing power
D. Implementation of rapid elasticity
Explanation: Metered utilization of cloud resources refers to payments made only for resources that are used. Cloud providers offer a pay-as-you-go model where customers are charged based on their usage of resources. Customers can easily scale up or down their usage of resources as per their needs and only pay for what they use.
