B. Verify that the OS supports hot swapping the RAM
C. Power down the server completely and then replace the RAM
D. Replace the RAM while the server is running

Answer: B

Explanation:
Explanation
Verify that the OS supports hot swapping the RAM. Before replacing the RAM on an entry-level server with hot-swappable components, the technician should verify that the operating system supports hot swapping of RAM.

NEW QUESTION # 37
Which of the following should a technician use in DNS to map a device to an IPv6 address?

A. AAAA
B. CNAME
C. MX
D. A

Answer: A

Explanation:
In DNS (Domain Name System), the AAAA record is used to map a domain or device to an IPv6 address. IPv6 addresses are 128-bit addresses, and the AAAA record is specifically designed for handling these larger addresses.
C : This record is used to associate a hostname with an IPv6 address in DNS.
Why the other options are incorrect:
A : An A record maps a domain to an IPv4 address, not an IPv6 address.
B : A CNAME (Canonical Name) record is used to alias one domain name to another but does not map to an IP address directly.
D : An MX (Mail Exchange) record is used to direct email traffic to the correct email servers, not to map devices to IP addresses This falls under the Networking domain of the CompTIA A+ Core 1 exam.

NEW QUESTION # 38
A user needs to upgrade the power supply of an older workstation to properly power a new graphics card.
Which of the following criteria should the technician check to ensure the power supply will support the upgraded workstation? (Select two).

A. Form factor
B. Efficiency rating
C. Modular cabling
D. Fan type
E. Wattage
F. Heat dissipation

Answer: A,E

Explanation:
The technician should check the wattage and the form factor of the power supply to ensure it will support the upgraded workstation. These are the two most important criteria for choosing a compatible and adequate power supply.
* Wattage: The wattage of a power supply is the maximum amount of power it can deliver to the components of the workstation. The wattage of the power supply should match or exceed the total power consumption of the components, especially the new graphics card, which is usually the most power-hungry part. If the power supply does not have enough wattage, it may cause instability, crashes, or damage to the workstation. To estimate the power consumption of the components, the technician can use a power supply calculator tool, such as the ones found in the web search results123. The technician should also add some headroom to the wattage, such as 20% to 50%, to account for peak power consumption, future upgrades, or power supply degradation.
* Form factor: The form factor of a power supply is the physical size and shape of the unit. The form factor of the power supply should fit in the case of the workstation and match the mounting holes and screws. The most common form factor for desktop power supplies is ATX, which measures 150 x 86 x
140 mm. However, some older or smaller workstations may use different form factors, such as SFX, TFX, or FlexATX. The technician should check the specifications of the workstation case and the power supply to ensure they have the same form factor.
Other criteria, such as efficiency rating, heat dissipation, fan type, and modular cabling, are not essential for supporting the upgraded workstation, but they may affect the performance, noise, or aesthetics of the power supply. The efficiency rating is the percentage of input power that is converted to output power, and it indicates how much power is wasted as heat. The heat dissipation is the ability of the power supply to cool itself and prevent overheating. The fan type is the design and size of the fan that cools the power supply, and it affects the noise level and airflow of the unit. The modular cabling is the feature that allows the user to detach unused cables from the power supply, and it helps to reduce clutter and improve airflow inside the case.

NEW QUESTION # 40
An administrator needs to configure RAID for a video-rendering workstation at minimal cost. The solution should have high read/write performance and maximum drive storage utilization.
Redundancy is not a concern. Which of the following RAID configurations should the administrator use?

A. 0
B. 1
C. 2
D. 3

Answer: D

Explanation:
The administrator should use RAID 0 for a video-rendering workstation at minimal cost. RAID 0, also known as striping, is a RAID configuration that splits data evenly across two or more disks, without parity information, redundancy, or fault tolerance. RAID 0 has the following advantages and disadvantages:
High read/write performance: RAID 0 can increase the data transfer rate by using multiple disks in parallel. This can improve the speed and efficiency of video rendering, which involves processing large amounts of data. RAID 0 can also reduce the latency and seek time of the disks, as the data is distributed across multiple spindles.
Maximum drive storage utilization: RAID 0 can use the full capacity of the disks, without wasting any space for parity or mirroring. This can lower the cost and increase the storage space for the workstation. For example, if two 500 GB disks are used in RAID 0, the total capacity of the array will be 1000 GB.
No redundancy or fault tolerance: RAID 0 does not provide any protection against data loss or disk failure. If one disk fails, the entire array will fail and the data will be unrecoverable. Therefore, RAID 0 should only be used for non-critical data that is backed up elsewhere, or for temporary files that can be recreated.
