672. Frage
Which of the following tools would a technician use to connect wires to an RJ45 connector?
Antwort: C
Begründung:
Comprehensive and Detailed Explanation From Exact Extract:
A crimper is specifically used to attach RJ45 connectors to the ends of network cables. It pressesthe connector pins into the cable's wires, establishing a secure electrical connection. A punchdown tool is used for wiring patch panels or keystone jacks, not for attaching connectors.

673. Frage
A technician is troubleshooting an all-in-one laser printer that prints a vertical line when making copies and scans. When users print or receive faxes, the output from the printer is correct. Which of the following should the technician examine to determine the cause of the issue?
Antwort: D
Begründung:
Comprehensive and Detailed Explanation From Exact Extract:
Since the issue only occurs during scanning and copying (not printing or faxing), the problem is isolated to the document feeder. A vertical line is typically caused by debris or damage on theglass under the ADF (Automatic Document Feeder), not on components related to printing.

675. Frage
Which of the following RAM characteristics allows for the most data bandwidth?
Antwort: A
Begründung:
The correct answer is D. Dual channel.
In the CompTIA A+ Core 1 (220-1201) hardware objectives, memory bandwidth refers to the amount of data that can be transferred between RAM and the CPU in a given amount of time.
Dual channel memory architecture increases bandwidth by:
Allowing the memory controller to access two memory modules simultaneously Effectively doubling the data transfer rate compared to single-channel configurations Improving overall system performance, especially in memory-intensive tasks Why the other options are incorrect:
A). CAS latency
CAS latency measures the delay before data is available after a request. Lower latency improves response time, but it does not significantly increase total bandwidth.
B). ECC
ECC (Error-Correcting Code) improves reliability by detecting and correcting errors, but it does not increase data transfer bandwidth.
C). High clock speed
Higher clock speed does increase bandwidth, but not as significantly as enabling dual channel, which allows parallel data transfer paths and provides a greater overall increase.
Final answer: D. Dual channel
676. Frage
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?
Antwort: A
Begründung:
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.
