Two from the bank, answered.

Real items, with the answer marked and the reason written out — the same format as all 100.

Operating Systems

Which Windows edition is designed for large enterprises and is the only one that supports joining an on-premises Active Directory domain as well as BitLocker, but is licensed through volume agreements rather than retail?

  1. AWindows EnterpriseCorrect
  2. BWindows Education
  3. CWindows Home
  4. DWindows Pro for Workstations

Why: Windows Enterprise is aimed at large organizations and is distributed through volume licensing rather than retail. It supports domain join, BitLocker, and advanced management features. Home lacks domain join and BitLocker.

Operational Procedures

Why is it important to maintain accurate, up-to-date documentation such as network diagrams and asset inventories?

  1. AIt speeds troubleshooting and supports consistent, informed decisionsCorrect
  2. BIt replaces the need for backups
  3. CIt encrypts all network traffic
  4. DIt increases the monitor refresh rate

Why: Accurate documentation helps technicians understand the environment quickly, reducing troubleshooting time and supporting good decisions. It does not encrypt traffic, change hardware behavior, or substitute for backups.

Questions

Asked before starting.

Is the practice really free, or does it stop after a few questions?

All 100 questions, the timed mock and the report are free with no sign-up. A free account only adds saving your progress.

Is your mock the same as the real CompTIA A+ Core 2?

No. Ours is 90 questions in 90 minutes; the real exam is 100 questions. Use the mock for stamina and section timing, not as a score predictor.
