State-specific content

This 25-question study variant combines selected foundational subjects from CompTIA A+ Exam. Each question has four choices and one best answer. Read all stated assumptions before choosing.

The 40-minute timer and 72% target (18 of 25) are ExamsLib practice settings only. They do not reproduce an official examination duration, scaled score, eligibility decision, or passing standard.

After submitting, review the explanation for every missed or guessed answer. Rework calculations without the choices, and record one rule or evidence check in an error log. Questions can recur between different variants and state pages; use a fresh variant to check understanding rather than memorization.

These questions are for study practice only and are not official exam questions. ExamsLib is independent of the test owner and licensing authorities.

Question 1

A tablet displays a clear image, but touch input fails across the screen. An external pointing device works. Which subsystem is most directly implicated?

Question 2

A laptop works well on Wi-Fi near an access point but disconnects behind several dense walls. Wired operation is stable. What factor is most relevant to investigate?

Question 3

A command-line exercise defines /reports/annual.txt as starting from the filesystem root and reports/annual.txt as starting from the current directory. Which is the absolute path?

Question 4

The help desk cannot reproduce a reported failure because its test uses a different account and different file. What should be improved?

Question 5

A proposed CPU fits the motherboard socket, but the board manufacturer does not list it as supported by the installed firmware. What should be checked before purchasing it?

Question 6

In a simplified IPv4 exercise, two hosts use mask 255.255.255.0: 192.168.40.10 and 192.168.40.200. What does the shared first three octets indicate under this mask?

Question 7

A user with reduced vision finds text too small on a high-resolution screen. Which setting directly addresses readable interface size without immediately replacing hardware?

Question 8

A laptop microphone works in one application but another says access is blocked by privacy settings. Which check is most direct?

Question 9

A hardware vendor provides both a device driver and a firmware update. Which statement best distinguishes them?

Question 10

All users can access an internal file server, but none can reach approved Internet sites. A single user computer is not uniquely affected. What scope should support investigate?

Question 11

A backup plan takes a full backup Sunday and a differential backup Tuesday. The differential contains all changes since Sunday full. Which backups are needed to restore Tuesday state under this model?

Question 12

After a configuration change, the problem becomes worse. The change record includes the prior settings and an approved rollback plan. What is the most controlled next step?

Question 13

A field laptop will be carried frequently and needs persistent storage with no moving mechanical parts in the storage device. Which listed storage type directly meets that requirement?

Question 14

A laptop uses the correct Wi-Fi network name, but authentication fails after the organization rotates its wireless credentials. What is a sensible first check?

Question 15

A virtualization exercise has 24 GB of host RAM and reserves 6 GB for the host. Each identical VM requires 4 GB, with no memory overcommit permitted. What is the maximum whole number of VMs under this memory rule?

Question 16

A newly installed application fails only when it accesses a restricted folder. The error explicitly identifies a denied write operation. What is the best-supported investigation?

Question 17

An office relies on mirrored drives and has no separate backup. A user deletes an important folder, and the deletion is reflected on the mirrored volume. What does this illustrate?

Question 18

A router translates several private client addresses to a shared public address. What should not be inferred solely from that translation?

Question 19

A required background service is stopped after every reboot. Its startup setting is disabled. Which configuration most directly explains the repeated behavior?

Question 20

A technician suspects a specific application causes high CPU use. Which observation would best test that hypothesis?

Question 21

A docked laptop sees two external monitors in display settings, but one is configured as disconnected. Both monitors work individually. What is the most appropriate first configuration check?

Question 22

A computer reaches a known server by its correct IP address but fails when using the server name. The relevant network route is working. Which service should be investigated first?

Question 23

A workstation display is set to turn off after five minutes, but the session remains unlocked. What control is missing if policy requires authentication before returning to the session?

Question 24

A user says a document disappeared after saving. The application recent-files list shows it in a different folder. What is the strongest first action?

Question 25

Frequently asked questions

Are these official exam questions?

These questions are for study practice only and are not official exam questions.

What does the practice target mean?

The target is 18 of 25 correct for this learning exercise. It does not convert to an official score or establish readiness or eligibility.

Will questions repeat?

The state pages share a common category bank. Different practice variants have different question sets, with some reuse in the new exam banks. Retaking the same variant returns the same questions.

How should I review a result?

Separate knowledge gaps, reading mistakes, and calculation errors. Explain why each distractor is wrong before attempting another variant.
