CompTIA Network+ N10-009 Syllabus Exam Questions Answers

Direct Connect refers to a dedicated network connection between an on-premises network and a cloud service provider (such as AWS Direct Connect). This link bypasses the public internet, providing a more reliable and higher-bandwidth connection. It may not inherently include encryption because it relies on the security measures of the dedicated physical connection itself. In contrast, other options like VPN typically involve encryption as they traverse the public internet.

Comprehensive and Detailed Explanation:

Since the switch supportsonly 10Gbps per port, achieving40Gbps throughputrequireslink aggregation(LACP), which combines multiple10Gbpslinks into onelogical interfacefor higher bandwidth.

Breakdown of Options:

A. 802.1Q tagging– VLAN tagging helps segment traffic but doesnot increase throughput.

B. Jumbo frames– Jumbo framesreduce overhead but do not increase bandwidth.

C. Half duplex– Half duplexrestricts communication,reducingperformance instead of improving it.

D. Link aggregation–Correct answer.LACP combines multiple10Gbpslinks to provide a40Gbpsconnection.

Comprehensive and Detailed Explanation:

Wi-Fi 6Eis thebest choiceforhigh-density environments, as it provideshigher speeds, more capacity, and lower latency.

Troubleshooting Methodology:

Confirming the Root Cause: After testing and confirming the theory, the next logical step is to address the issue by implementing a solution.

Implementation of the Solution:

Resolve the Issue: Implement the identified solution to rectify the problem. This step involves making necessary changes to the network configuration, replacing faulty hardware, or applying software patches.

Documentation: Document the solution and the steps taken to resolve the issue to provide a reference for future troubleshooting.

Comparison with Other Steps:

Determine Resolution Steps: This is part of the implementation process where specific actions are outlined, but the actual next step after testing is to implement those steps.

Duplicate the Problem in a Lab: This step is typically done earlier in the troubleshooting process to understand the problem, not after confirming the root cause.

Present the Theory for Approval: In some scenarios, presenting the theory might be necessary for major changes, but generally, once the root cause is confirmed, the solution should be implemented.

Final Verification:

After implementing the solution, it is important to verify that the issue is resolved and that normal operations are restored. This may involve monitoring the network and testing to ensure no further issues arise.
