- A
Add additional BGP peers to the Direct Connect connection
Why wrong: Does not address drops.
- B
Increase the MTU on the virtual interface to 1500
Why wrong: MTU increase may cause fragmentation issues.
- C
Check the BGP session status and metrics on the virtual interface
BGP issues can cause connection resets.
- D
Increase the bandwidth of the VPN connection as a backup
Why wrong: Not relevant.
- E
Check the physical layer metrics such as light levels and signal strength
Physical layer issues cause drops.

ANS-C01 Network Management and Operations Practice Question
This ANS-C01 practice question tests your understanding of network management and operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer is troubleshooting intermittent connectivity issues between an on-premises data center and a VPC over a Direct Connect connection. The engineer reviews the CloudWatch metrics for the virtual interface and sees an increase in 'ConnectionReset' and 'PacketDropRate'. Which TWO actions should the engineer take to resolve the issue? (Choose TWO.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the BGP session status and metrics on the virtual interface
Options C and E are correct. Checking the BGP session status and metrics on the virtual interface helps identify if there are BGP-related issues such as route flapping or session drops that could cause connectivity problems. Checking physical layer metrics like light levels and signal strength can reveal underlying physical issues with the Direct Connect connection. Option A is incorrect because adding BGP peers does not address the symptoms of ConnectionReset and PacketDropRate. Option B is incorrect because increasing MTU could actually increase drop rates if the underlying physical layer has issues. Option D is incorrect because the VPN connection is not directly related to Direct Connect and increasing its bandwidth would not resolve issues with the Direct Connect connection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
