CompTIA SK0-005 Exam Questions

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.

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.

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.

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.

In an active-passive load balancing configuration, one path (or server) handles all the traffic while the other remains in standby mode, ready to take over if the active path becomes unavailable. This setup is typically monitored via a heartbeat mechanism, where the standby server checks the availability of the active server and takes over when it detects a failure.

Heartbeat (Answer B): This term refers to the monitoring process that checks the availability of the active path in an active-passive configuration.

Most recently used (Option A): This describes a load-balancing method where the most recently used path or server is prioritized, but it doesn't describe an active-passive setup.

Link aggregation (Option C): This refers to combining multiple network connections for increased throughput, not for failover purposes.

Round robin (Option D): This load-balancing method alternates traffic between all available paths, which doesn't match the active-passive description.
