A server administrator implemented a new backup solution and needs to configure backup methods for remote sites. These remote sites have low bandwidth and backups must not
interfere with the network during normal business hours. Which of the following methods can be used to meet these requirements? (Select two).
Archive is a method of storing historical data that is not frequently accessed or modified. Archive can reduce the amount of data that needs to be backed up and save bandwidth and storage space. Differential is a method of backing up only the data that has changed since the last full backup. Differential can also save bandwidth and storage space, as well as speed up the backup process.

Server Management: Server Hardware Installation and Management2, Module 2, Lesson 5
A Linux server was recently updated. Now, the server stops during the boot process with a blank screen and ans> prompt. When of the following is the MOST likely cause of this issue?
The most likely cause of this issue is that the UEFI boot was interrupted by a missing Linux boot file, such as grub.cfg or vmlinuz, which are essential for loading the Linux kernel and booting the system. The s> prompt indicates that the system entered into UEFI Shell mode, which is a command-line interface for troubleshooting UEFI boot issues. The administrator can use UEFI Shell commands to locate and restore the missing boot file or change the boot order. Verified Reference: [UEFI Shell Guide]
A server recently started sending error messages about running out of memory while in use. After a maintenance period during which more memory was added, the server is still unable to consistently remain powered on. Which of the following should the technician check first?
When troubleshooting memory-related errors, it's essential to consider several key factors:
Memory Compatibility: Memory modules must match the specifications supported by the motherboard (e.g., DDR4 vs. DDR5, ECC vs. non-ECC, buffered vs. unbuffered). Using incompatible RAM can cause boot failures, crashes, or instability.
Memory Speed: While RAM speed mismatches can affect performance, they typically do not cause a server to fail to power on. Most systems automatically adjust to the slowest module.
Memory Slots: Incorrect installation or damaged slots could be an issue, but the priority is to check compatibility first.
Boot Order: This setting controls the sequence in which devices boot the OS, which is unrelated to memory-related power issues.
Since the server remains unstable after adding memory, the most likely issue is an incompatibility with the motherboard. The first step is to verify whether the newly installed RAM meets the server's hardware requirements.
A technician is configuring a server that will need to accommodate a planned network upgrade. All hosts will be changed from 10Gb copper to 25Gb fiber. Which of the following would best suit the requirements?
The upgrade involves transitioning from 10Gb copper to 25Gb fiber, which requires appropriate network interface hardware:
FCoE (A) - Fibre Channel over Ethernet: This protocol allows Fibre Channel to run over Ethernet networks, but it does not address the physical change from copper to fiber.
VLAN ID (B): VLANs segment networks but do not impact the physical connectivity (copper vs. fiber).
SFP (C) - Small Form-factor Pluggable: SFP transceivers are hot-swappable modules used in network interfaces to support fiber connections. A 25Gb SFP28 transceiver would be required for the transition from 10Gb copper to 25Gb fiber. This is the correct answer.
HBA (D) - Host Bus Adapter: HBAs are typically used for storage connectivity (such as Fibre Channel SANs), not general network upgrades.
Since SFP modules allow servers to support fiber connections, this is the best choice for upgrading from 10Gb copper to 25Gb fiber.
Under which of the following should a technician implement scripting?
Comprehensive Detailed Explanation with all CompTIA Server+ SK0-005 Study Guide Reference:
Scripting is commonly used to automate repetitive step-by-step tasks in server management, such as:
Automating system configurations.
Running maintenance jobs like backups or log file cleanup.
Performing administrative tasks like provisioning new users or setting permissions.
This automation improves efficiency and reduces the likelihood of human error. Referencing the SK0-005 guide, scripting is a best practice for simplifying tasks that involve consistent, repeatable processes.
