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.

C. Wireless protocol settings
D. ONS servers
Explanation: The technician should check the MAC filtering list next as the new router may
have a different MAC address than the old router.

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.
