CompTIA SK0-005 Exam Questions

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

When configuring a server rack, it's important to consider:

A) Floor load limitations: Server racks can be extremely heavy, especially when filled with equipment like blade servers. It is crucial to ensure that the floor can handle the load to avoid structural damage or failure.

B) Rack balancing: Properly distributing the weight in a server rack is important for stability. Heavier equipment should generally be placed at the bottom to prevent the rack from becoming top-heavy and risking a tip-over.

C) Proper lifting techniques: Using correct lifting techniques when placing servers into a rack is vital to prevent personal injury.

A faulty PSU needs replacement, and the management team wants a solution to prevent future downtime.

Solution:Implementredundancy(Option D):

Redundant power supplies ensure that if one fails, the other takes over seamlessly.

Separate circuits, load balancing, and server monitoring are important but do not directly prevent PSU failures.
