To debug possible database issues on an Infoblox appliance, which file should an administrator review?
Correct Answer: D
Comprehensive and Detailed In-Depth Explanation:Debugging database issues (e.g., sync failures, corruption) requires detailed logs specific to NIOS operations. Here's the breakdown:
* A (messages file in support bundle):The "messages" file contains general system logs (e.g., kernel events), not NIOS-specific database activity. It's less relevant here. Incorrect.
* B (infoblox.log via GUI):The GUI allows downloading logs (Grid > Logs > Download), but these are often filtered or summarized, not the raw, comprehensive database logs needed for deep debugging.
Incorrect.
* C (infoblox.log in support bundle):The "infoblox.log" in a support bundle (generated via CLI or GUI:
Grid > Support Bundle) is the primary NIOS application log, capturing detailed database events (e.g., bloxSync errors, transaction failures). This is the go-to file for database troubleshooting, as emphasized in INE labs. Correct.
* D (messages via GUI):Similar to A, this is a general system log, not NIOS-specific, and lacks database granularity. Incorrect.
* Practical Example:In an INE troubleshooting scenario, you'd download a support bundle after a Grid sync failure, extract "infoblox.log," and search for database error codes to diagnose the issue.
