Question
The network operations center has reported dramatically fewer entries in the logs tab of a new Virtual Service after the first 30 minutes of operation. What is the likely cause of the reduced log volume?
Options
- ALogs are being sent to syslog instead of the logs tab.
- BThe Service Engine has disabled logging due to high CPU load.
- CNon-significant logs are not enabled.
- DA widespread internet outage has occurred.

Explanation
There appears to be an error in the provided answer key - D is almost certainly wrong, and C is the correct answer. Here's why:
In platforms like VMware NSX Advanced Load Balancer (AVI Networks), Virtual Services distinguish between significant logs (errors, policy violations, anomalies) and non-significant logs (routine successful connections). If non-significant logging is not enabled, the system logs heavily during initial bursts of varied traffic, then volume drops sharply as traffic normalizes and only significant events are captured - matching the "dramatic reduction after 30 minutes" pattern exactly.
Why the distractors are wrong:
- A - Syslog redirection would move logs to another destination, not reduce total volume; the NOC would simply look elsewhere.
- B - Load balancers don't self-disable logging under CPU pressure as a standard behavior; this would also be a serious operational red flag, not a silent default.
- D - An internet outage would still generate more logs (timeouts, resets, errors), not fewer; and it has nothing to do with a Virtual Service being "new."
Memory tip: Think "30 minutes = new traffic settled = only significant events remain." When you see log volume drop after an initial period on a new Virtual Service, always suspect the non-significant log filter - it's a classic AVI/NSX ALB gotcha on exams.
Note for the exam taker: If your source material marks D as correct, flag it - this appears to be a question bank error. The answer that aligns with actual platform behavior is C.
