ANS-C01 Network Implementation Practice Question
A company is experiencing intermittent connectivity issues between its on-premises network and AWS via a Direct Connect connection. The link is up, but packet loss is observed. Which test should the network engineer perform first to isolate the issue?
⚠ Common exam trap
Many exam-takers assume pinging the virtual private gateway (Option B) is sufficient to verify the link, but it only confirms reachability and cannot isolate the specific hop causing packet loss, which is the primary goal of troubleshooting intermittent issues.
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
✓
Run a traceroute with MTR
MTR (My TraceRoute) combines the functionality of traceroute and ping to provide per-hop latency and packet loss statistics. This allows the engineer to pinpoint whether the packet loss is occurring on the Direct Connect link itself, the customer gateway, or somewhere in the transit path, rather than just confirming end-to-end reachability.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Run a traceroute with MTR
Why this is correct
MTR shows loss per hop, helping identify the problematic segment.
- ✗
Ping the virtual private gateway
Why it's wrong here
Ping only tests reachability, not per-hop loss.
- ✗
Perform a DNS lookup
Why it's wrong here
DNS is unrelated to packet loss.
- ✗
Run a speed test
Why it's wrong here
Speed test measures throughput, not packet loss.
