CompTIA SK0-005 Exam Questions

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.

A perpetual license is a one-time purchase that allows the software to be used indefinitely without recurring costs. This meets the requirement of a non-renewing, one-time capital expense.

Perpetual (Answer D): This is a one-time purchase and does not require renewal, making it ideal for capital expenditure.

Open-source (Option A): Open-source software is usually free but may not meet specific licensing requirements.

Subscription (Option B): This typically involves recurring payments, which contradicts the non-renewing expense requirement.

Volume (Option C): Volume licenses are used for purchasing multiple licenses at a discount but may still involve subscription-based renewals.

Scenario:Four disks, requiring redundancy and maximum usable capacity.

RAID Level:RAID 10(Option D) is the best choice:

RAID 10 combines mirroring (redundancy) and striping (performance).

RAID 0 lacks redundancy, RAID 1 provides less capacity, and RAID 5 requires more
