ANS-C01 Network Implementation Practice Question
A network engineer is troubleshooting an AWS Direct Connect connection that is experiencing high latency. The connection is a 1 Gbps dedicated connection. The engineer notices that the link utilization is at 90%. What is the MOST likely cause of the high latency?
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
✓
High bandwidth utilization causing queuing
High bandwidth utilization (90%) leads to queuing delays as packets wait in buffers, increasing latency. Option A is incorrect: the virtual interface type (private vs public) does not directly cause high latency. Option B is incorrect: BGP keepalive timer misconfiguration affects BGP session stability, not latency. Option D is incorrect: jumbo frames can reduce latency by reducing overhead, not increase it.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The virtual interface is configured as private instead of public
Why it's wrong here
Incorrect; the type of virtual interface does not directly impact latency.
- ✗
BGP keepalive timer misconfiguration
Why it's wrong here
Incorrect; BGP timers affect routing convergence, not link latency.
- ✓
High bandwidth utilization causing queuing
Why this is correct
Correct; when utilization is high, packets are queued, increasing latency.
- ✗
The use of jumbo frames
Why it's wrong here
Incorrect; jumbo frames reduce overhead and can lower latency.
