Objective 3.5220-1201

3.5 Given a scenario, install and configure motherboards, central processing units (CPUs), and add-on cards.

Objective 3.5 sits in Hardware, which carries 25% of the A+ Core 1 exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

HardwareEasy

A technician installs a two-way mirror space on a newly added storage controller card to protect files on a small office server. How many drive failures can this configuration tolerate before data is lost?

Correct.

The concept

Storage Spaces mirror resiliency configurations duplicate data across drives to provide fault tolerance during hardware failures.

Why this answer

Two-way mirroring keeps two copies of data, so the loss of a single drive still leaves a full copy available, tolerating exactly one drive failure.

  • AThis describes a simple space, which stripes data with no redundancy and loses everything if any drive fails.
  • BNo configuration described tolerates three simultaneous failures; this exaggerates the fault tolerance of any listed option.
  • This is the correct behavior of a two-way mirror space.
  • DThis level of tolerance matches three-way mirroring or dual parity, not a two-way mirror.

Now you: objective 3.5 questions

No account needed. The explanation opens when you answer.

Sample question 1 of 3

HardwareModerate

An administrator installs a new SATA expansion card to host a storage pool for temporary scratch data during video rendering. Performance and capacity matter, but the data does not need to survive a drive failure. Which resiliency configuration should be chosen?

Sample question 2 of 3

HardwareModerate

A technician adds a storage controller card to build an archive repository for nightly backups. Storage capacity efficiency is the priority, and slower write speed is acceptable. Which resiliency configuration best fits this workload?

Sample question 3 of 3

HardwareHard

A database workload on a newly installed storage controller card must survive two simultaneous drive failures while keeping write performance as high as possible. Which resiliency configuration meets both requirements better than the alternative offering the same fault tolerance?

That’s 3 of the full A+ Core 1 bank.
