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.
An administrator is tasked with building an environment consisting of four servers that can each serve the same website. Which of the following concepts is described?
Load balancing is a method used to distribute incoming network traffic across multiple servers. In this scenario, the administrator is tasked with ensuring that all four servers can serve the same website, which is a typical use case for load balancing.
Load balancing (Answer A): Distributes web traffic across multiple servers to ensure availability and reliability.
Direct access (Option B): Refers to client devices connecting directly to a network resource, unrelated to the described scenario.
Overprovisioning (Option C): Refers to allocating more resources than are currently needed, not relevant to load distribution.
Network teaming (Option D): Involves combining multiple network interfaces for redundancy or increased throughput but doesn't address server distribution.

A server administrator created a new script and included the path to the script binary as the first line of the script. Which of the following scripting languages did the administrator most likely use?
In Bash (a Unix/Linux shell scripting language), it is common to include the shebang (#!) followed by the path to the interpreter (e.g., #!/bin/bash) on the first line of the script. This tells the operating system which interpreter to use to execute the script.
Bash (Answer C): Bash scripts often start with a shebang line that specifies the path to the binary (#!/bin/bash).
Batch (Option A): Batch scripts (used in Windows) do not require a path to the interpreter on the first line.
Java (Option B): Java is a compiled language, not a scripting language, so this does not apply.
PowerShell (Option D): PowerShell scripts (.ps1 files) do not typically require specifying the interpreter path on the first line.
