Infoblox Qualified NIOS DDI Expert - INE Sample Questions (Q41-Q46):

NEW QUESTION # 41
You accidentally deleted several DNS entries from the Grid. How can you recover from this mistake with the least service disruption?

A. Restore the records from the recycle bin
B. Restore the database from the last backup
C. Force HA failover on the GM, if it is an HA pair
D. Promote a GMC to be the new GM

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:Accidentally deleting DNS entries (e.g., A records) in NIOS requires a recovery method that minimizes downtime and complexity. Here's the analysis:
* Recycle Bin Feature:NIOS includes a Recycle Bin (Data Management > DNS > Recycle Bin) that temporarily stores deleted objects (e.g., zones, records) unless permanently purged or the bin is disabled. Restoring from here is instantaneous and doesn't interrupt services.
* Options:
* A:Restoring from a backup (Grid > Grid Manager > Backup > Restore) replaces the entire database, requiring service restarts and potentially losing post-backup changes. High disruption.
Incorrect.
* B:Promoting a Grid Master Candidate (GMC) to Grid Master (GM) shifts control but doesn't recover deleted records-it's for GM failure, not data loss. Irrelevant. Incorrect.
* C:Forcing HA failover on the GM switches active/passive nodes but doesn't restore data, as both share the same database. No effect. Incorrect.
* D:Restoring from the Recycle Bin (select records > Restore) reverts the deletion with no service impact, assuming the bin is enabled (default in NIOS). Correct.
* Practical Example:In an INE lab, you'd delete an A record, navigate to the Recycle Bin, restore it, and verify DNS resolution-all without downtime, testing troubleshooting skills.
* Caveat:If the Recycle Bin is disabled or entries are purged, backup restoration (A) becomes necessary, but the question implies least disruption, favoring D.References:Infoblox NIOS Administrator Guide - Recycle Bin; INE Course Content: NIOS DDI DNS Troubleshooting.

NEW QUESTION # 42
To debug possible database issues on an Infoblox appliance, which file should an administrator review?

A. infoblox.log file in the support bundle
B. infoblox.log file downloaded via the GUI
C. messages file downloaded via the GUI
D. messages file in the support bundle

Answer: A

Explanation:
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.

NEW QUESTION # 43
How does an administrator obtain new NIOS releases?

A. Download fromhttps://support.infoblox.com
B. Contact the Infoblox Account Manager for a Support Bundle
C. In Grid UI, go to Grid > Software > Download
D. Contact Infoblox Technical Support for a Software Bundle

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:Obtaining new NIOS software releases follows a standardized process tied to Infoblox's support infrastructure:
* Official Method:New releases (e.g., NIOS 8.6.x) are available for download from theInfoblox Support Portal(https://support.infoblox.com) under the "Downloads" section. Admins log in with valid credentials, select the appliance model, and download the .upgrade file.
* Options Analysis:
* A:"Grid > Software > Download" isn't a valid path in Grid Manager. The UI supports uploading and distributing releases (Grid > Upgrade), but not direct downloading. Incorrect.
* B:Technical Support can assist with issues or provide files in rare cases (e.g., beta releases), but it's not the standard method-self-service via the portal is preferred. Incorrect.
* C:Account Managers handle sales, not software distribution. "Support Bundle" is also a misnomer-it's for diagnostics, not upgrades. Incorrect.
* D:The support portal is the documented, primary source for NIOS releases, aligning with INE's focus on Grid upgrade procedures. Correct.
* Steps:Download the file, upload it via Grid Manager (Grid > Upgrade > Upload), and initiate the upgrade process.
* Practical Example:In an INE lab, you'd download NIOS 8.6.2 from the portal, upload it, and test a Grid-wide upgrade, troubleshooting any distribution failures.References:Infoblox NIOS Administrator Guide - Obtaining Software Releases; INE Course Content: NIOS DDI Grid Deployment.

NEW QUESTION # 44
The Grid is comprised of all single members. Which member will upgrade first?

A. The Grid Master Candidate upgrades first
B. The Grid Master upgrades first
C. You can choose which member upgrades first
D. The Reporting server upgrades first

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation:Upgrading a Grid of single members (no HA pairs):
* A:Admins define Upgrade Groups or schedules (Grid > Upgrade), choosing the order (e.g., "Member1 first"). Correct.
* B:GM typically upgrades last by default to maintain control, but this can be overridden. Incorrect.
* C:Reporting server (if present) has no priority-user-defined. Incorrect.
* D:GMC upgrades only if promoted, not inherently first. Incorrect.
* Practical Example:In an INE lab, schedule Member2 first, test upgrade, and troubleshoot sequence issues.References:Infoblox NIOS Administrator Guide - Upgrade Scheduling; INE Course Content:
NIOS DDI Grid Deployment.

NEW QUESTION # 45
Which stage of a NIOS upgrade is generally expected to take the shortest time?

A. Upgrade
B. Upload
C. Distribute
D. Test

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:NIOS upgrade stages (Grid > Upgrade):
* A (Upload):Uploading the .upgrade file (e.g., 50-200 MB) to the GM is quick-seconds to minutes, depending on network speed. Shortest. Correct.
* B (Test):Validates file integrity/compatibility-fast but longer than upload (e.g., 1-2 minutes).
Incorrect.
* C (Distribute):Sending the file to all members takes longer, proportional to Grid size/network (e.g., 5-
15 minutes). Incorrect.
* D (Upgrade):Rebooting and applying the update per member is the longest (e.g., 10-30 minutes total).
Incorrect.
* Practical Example:In an INE lab, upload takes 30s, while distribution and upgrade take 10+ minutes, testing Grid deployment timing.References:Infoblox NIOS Administrator Guide - Upgrade Process; INE Course Content: NIOS DDI Grid Deployment.
