Question 3

A technician is troubleshooting issues occurring on a user's mobile device. Applications and the OS have slow response times, even when performing simple tasks, such as writing an email. Additionally, new applications occasionally fail to launch. Which of the following should the technician do next?



Answer : B

The symptoms --- slow response and failed app launches --- indicate that thedevice's memory or processing resources are overutilized. Closing unnecessary apps can free up RAM and CPU resources, improving performance.

Option A:Overheating may cause sluggishness, but that's not indicated here.

Option C:Factory reset is a last resort, not the next logical step.

Option D:Battery health would affect uptime, not system speed.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 1.6: Given a scenario, configure basic mobile device network connectivity and application support.


Question 4

A customer reports that a workstation has no internet connectivity. A technician confirms the port is disabled. Which of the following is most likely responsible for the issue?



Answer : C

A managed switch allows an administrator to enable or disable individual ports as part of network security and management. If a port on a managed switch has been disabled, the device connected to that port will lose connectivity, which matches the scenario described.

Option B (Hybrid):Mix of public and private --- does not imply industry collaboration.

Option D (Private):Dedicated to a single organization.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 2.1: Compare and contrast cloud computing concepts.


Question 6

A technician needs to move a workstation to a different logical network segment. Which of the following technologies should the technician use?



Answer : B

AVLAN (Virtual LAN)is used to logically segment a network without requiring physical separation. It enables grouping devices based on function or department regardless of their physical location.

Option A (DHCP):Assigns IP addresses dynamically but doesn't create network segments.

Option C (DNS):Resolves domain names to IP addresses, not used for network segmentation.

Option D (VPN):Provides secure remote access but does not relate to logical segmentation within a local network.

CompTIA A+ Core 1 Exam Objective Reference:

Objective 2.3: Explain common logical networking concepts.


Question 7

Which of the following describes the function of an injector?



Answer : B

A PoE injector is used to add power to an Ethernet cable, enabling the cable to deliver both power and data. This is crucial when connecting to PoE-enabled devices like IP cameras or wireless access points that are far from power outlets.
