The purpose of this practice assessment is to comprehensively evaluate candidate *
readiness for the CompTIA A+ certification exam. This guide measures the foundational*
technical skills and applied professional knowledge required to support modern core *
IT infrastructures. Through a structured series of multiple-choice and complex, *
scenario-based questions, candidates must demonstrate analytical decision-making *
and technical problem-solving capabilities. The content emphasizes real-world *
application, regulatory compliance, and professional ethics necessary for help desk *
, support, technical remediation, and field service operations across enterprise environments.*
SECTION ONE: QUESTIONS 1–100
Question 1
A help desk technician is troubleshooting a user's workstation that shuts down randomly after a few
minutes of heavy processing. The technician notices the internal fans are spinning rapidly before the
system powers off. Which of the following components should be inspected first?
A. Power supply unit wattage
B. Central processing unit thermal paste
C. Hard disk drive sectors
D. Random access memory seated modules
🟢 Correct answer
B. Central processing unit thermal paste
🔴 RATIONALE: Random shutdowns under heavy load combined with excessive fan speeds typically
point to CPU overheating, which is frequently caused by degraded or improperly applied thermal paste.
Question 2
An enterprise workstation contains sensitive corporate financial data. According to standard security best
practices and data handling policies, which of the following is the most secure method to decommission
a mechanical hard drive before disposal?
A. Standard operating system high-level formatting
B. Overwriting the drive with a single pass of zeroes
C. Exposing the magnetic platters to a certified degausser
D. Deleting the partition table via disk management tools
🟢 Correct answer
C. Exposing the magnetic platters to a certified degausser
🔴 RATIONALE: Degaussing neutralizes the magnetic fields on mechanical platters, rendering the data
completely unrecoverable and satisfying regulatory compliance for media sanitization.
Question 3
,A technician needs to configure a wireless router for a small branch office. To ensure the highest level of
encryption and security for the wireless local area network, which protocol must be implemented?
A. WEP
B. WPA
C. WPA2-Enterprise
D. WPA3-Enterprise
🟢 Correct answer
D. WPA3-Enterprise
🔴 RATIONALE: WPA3-Enterprise delivers the most robust cryptographic algorithms, including 192-bit
cryptographic strength, protecting enterprise networks against credential cracking attacks.
Question 4
A network engineer is configuring a new server that must automatically assign IP addresses, subnet
masks, default gateways, and DNS server addresses to client workstations on the local network. Which
network service must be active?
A. DNS
B. DHCP
C. HTTP
D. SMTP
🟢 Correct answer
B. DHCP
🔴 RATIONALE: The Dynamic Host Configuration Protocol (DHCP) dynamically automates the
assignment of IP configuration settings to network clients, eliminating manual addressing errors.
Question 5
While working on an open computer chassis, a technician accidentally drops a small screw onto the
motherboard. To prevent damage to the delicate integrated circuits, what tool should the technician use
to retrieve it?
, A. A high-powered handheld magnet
B. Needle-nose metal pliers
C. A specialized non-magnetic pickup tool
D. Tweezers wrapped in plastic tape
🟢 Correct answer
C. A specialized non-magnetic pickup tool
🔴 RATIONALE: A non-magnetic parts retriever ensures that no electrostatic discharge or destructive
magnetic fields are introduced to the motherboard circuits during recovery.
Question 6
A user reports that their corporate laptop cannot connect to the internal network after returning from an
off-site business trip. The technician checks the IP address configuration and notes it displays
169.254.10.45. Which of the following issues does this address indicate?
A. The laptop has successfully connected to the local loopback address.
B. The laptop failed to contact a DHCP server and assigned an APIPA address.
C. The laptop is communicating over a secure corporate IPv6 tunnel.
D. The laptop has been assigned a static IP by the domain controller.
🟢 Correct answer
B. The laptop failed to contact a DHCP server and assigned an APIPA address.
🔴 RATIONALE: Addresses in the 169.254.0.0/16 range are Automatic Private IP Addressing (APIPA)
allocations, signifying a complete failure to contact a dynamic configuration server.
Question 7
A remote employee needs to establish a secure, encrypted tunnel from a public Wi-Fi hotspot back to the
corporate office network to access internal file shares safely. Which technology is required to fulfill this
requirement?
A. NAT
B. VPN
