CompTIA A+ Certification Exam: Core 1 Sample Questions (Q658-Q663):

NEW QUESTION # 658
Which of the following connectors is found on an optical networking cable?

A. Lightning
B. USB-C
C. RJ45
D. LC

Answer: D

Explanation:
Comprehensive and Detailed Step-by-Step
LC Connector (Lucent Connector):
LC is a type of fiber optic connector commonly used in optical networking cables. It is small, compact, and widely used for high-speed data transfer over fiber optic networks.
LC connectors are specifically designed for fiber optic cables, making them the correct answer.
Incorrect Options:
A . RJ45: RJ45 connectors are used for Ethernet cables (twisted-pair copper cabling) and are not compatible with optical networking cables.
C . USB-C: USB-C is a connector type used for general-purpose data transfer, charging, and video output, not for optical networking.
D . Lightning: Lightning connectors are proprietary to Apple devices and are not used in optical networking.
Key Takeaway:
The LC connector is specifically designed for fiber optic cables, making it the correct answer for optical networking.

NEW QUESTION # 659
A computer runs normally for several minutes, gradually runs slower, and then shuts down without warning. Which of the following resolves this issue?

A. Swapping the power supply
B. Upgrading the memory
C. Replacing the fans
D. Adding drive space

Answer: C

Explanation:
The key clue is the sequence: normal operation, gradual slowdown, and then sudden shutdown.
That pattern is typical of overheating. As temperature rises, modern CPUs and GPUs may throttle performance to reduce heat; if cooling remains inadequate, the system may lock up or shut down to prevent damage. The Quentin Docter study guide specifically states that overheating components may cause intermittent shutdowns and that a PC working for a few minutes and then locking up is probably experiencing a heat sink or fan problem. It recommends checking all fans and heat sinks first. The study guide also notes that motherboards often include CPU heat and fan sensors that can shut the computer down before damage occurs if active cooling fails.
Upgrading RAM or adding drive space could improve some performance issues, but they would not usually cause a heat-related shutdown. A failing power supply can cause shutdowns, but the gradual slowdown before power-off makes fan/cooling failure the better match.

NEW QUESTION # 660
Which of the following devices has ACL capabilities?

A. Firewall
B. DSL
C. Unmanaged switch
D. PoE injector

Answer: A

Explanation:
Firewalls are specifically designed to monitor, filter, and control network traffic using Access Control Lists (ACLs). ACLs define which traffic is allowed or denied based on parameters like IP address, protocol, or port.
From CompTIA A+ 220-1101 Official Study Guide, Objective 2.2 - Networking hardware and security:
"Firewalls use access control lists (ACLs) to allow or deny traffic based on rules. Unmanaged switches and PoE injectors do not support ACLs." Verified Source:

NEW QUESTION # 661
A healthcare facility is printing government documents on preprinted forms. The output has shifted downward on the paper and the printed data is not aligned with the blank spaces on the forms. Which of the following should a technician do first?

A. Verify that the correct paper type is loaded into the tray.
B. Ensure that the pickup rollers are firmly gripping the paper.
C. Make sure that PostScript drivers are being used.
D. Check the orientation settings of the printer.

Answer: D

Explanation:
When printed content is shifted and no longer aligns with preprinted form fields, the most common cause is incorrect page orientation or layout settings. Verifying and correcting the printer's orientation settings ensures the print job aligns properly with the preprinted areas.

NEW QUESTION # 662
An office is experiencing frequent wireless outages and slow network speeds. A technician confirms that all wireless devices are experiencing the same symptoms. Which of the following should the technician do to determine whether the issue is external or internal?

A. Connect a machine using Ethernet and test connectivity.
B. Perform a policy update on Active Directory and reset network settings.
C. Check the DNS configuration to make sure it is correct.
D. Restart all devices and ensure they join the workgroup.

Answer: A

Explanation:
By connecting a device directly to the network via Ethernet, the technician can determine if the issue is isolated to the wireless network or affects the entire network. If the wired connection works properly, the problem is internal to the wireless network; if not, the issue is likely external (e.g., with the ISP or modem).
