CompTIA A+ Competency Workshop
Comprehensive Finals Test (Qns & Ans)
2025
1. Which of the following types of memory is non-volatile and
can be electrically erased and reprogrammed?
- A. SRAM
- B. DRAM
- C. Flash memory
- D. ROM
ANS: C. Flash memory
©/2025
, Rationale: Flash memory is non-volatile, meaning it retains
data without power, and can be electrically erased and
reprogrammed, making it widely used in SSDs and USB drives.
2. Which of the following network topologies provides the
highest redundancy and fault tolerance?
- A. Bus
- B. Ring
- C. Star
- D. Mesh
ANS: D. Mesh
Rationale: In a mesh topology, each device is connected to
multiple other devices, providing high redundancy and fault
tolerance as multiple paths are available for data transmission.
Fill-in-the-Blank Questions
3. The __________ protocol is used for secure remote access
and operates over port 22.
ANS: SSH
©/2025
, Rationale: Secure Shell (SSH) is a protocol used for secure
remote access to network devices and operates over port 22,
providing encrypted communication.
4. The process of preparing a hard disk drive for use by dividing
it into logical storage units is called __________.
ANS: partitioning
Rationale: Partitioning is the process of dividing a hard disk
drive into logical storage units, allowing the creation of multiple
independent file systems on a single physical drive.
True/False Questions
5. True or False: The main function of a DNS server is to
translate domain names into IP addresses.
ANS: True
Rationale: The Domain Name System (DNS) translates
domain names (e.g., www.example.com) into IP addresses (e.g.,
192.168.1.1) to facilitate internet navigation.
6. True or False: An uninterruptible power supply (UPS)
provides both surge protection and battery backup power during
an outage.
©/2025
, ANS: True
Rationale: A UPS provides surge protection to safeguard
against voltage spikes and offers battery backup power to
maintain operation during power outages.
Multiple Response Questions
7. Which of the following are features of solid-state drives
(SSDs)? (Select all that apply)
- A. No moving parts
- B. Faster data access times
- C. Higher power consumption
- D. Greater durability
ANSs: A, B, D
Rationale: SSDs have no moving parts, resulting in faster
data access times and greater durability compared to traditional
hard drives. They also consume less power.
8. Which of the following are types of malware? (Select all that
apply)
- A. Virus
