Infoblox Qualified NIOS DDI Expert - INE Sample Questions (Q45-Q50):

NEW QUESTION # 45
To debug possible database issues on an Infoblox appliance, which file should an administrator review?

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

Answer: D

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 # 46
What does VRRP stand for?

A. Variable Rate Response Packet
B. Variable Route Recovery Protocol
C. Virtual Router Redundancy Protocol
D. Vital Router Response Protocol

Answer: C

Explanation:
Comprehensive and Detailed In-Depth Explanation:VRRP is the protocol Infoblox uses for HA:
* D:Virtual Router Redundancy Protocol(RFC 3768) provides IP redundancy by sharing a virtual IP (VIP) between routers (or NIOS nodes). Correct.
* A/B/C:Fictional acronyms-VRRP is a well-defined standard. Incorrect.
* Practical Example:In an INE lab, you'd configure VRRP for an HA pair, test failover, and troubleshoot VRRP packets, reinforcing HA concepts.References:RFC 3768 - VRRP; Infoblox NIOS Administrator Guide - HA; INE Course Content: NIOS DDI Grid Deployment.

NEW QUESTION # 47
What is the correct order of a NIOS upgrade?

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

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:A NIOS software upgrade follows a structured process in Grid Manager (Grid > Upgrade):
* Correct Order:
* Test Upload:Upload the .upgrade file (e.g., NIOS 8.6.2) and test it for integrity/compatibility (checks file checksum, version support).
* Distribute:Push the file to all Grid members, ensuring each has the update locally.
* Upgrade:Execute the upgrade, rebooting members per the schedule (e.g., passive nodes first).
* Why A:"Test Upload" combines the upload and initial validation steps, followed by distribution and execution. NIOS documentation uses this sequence for clarity.
* Options:
* B:Splits Test and Upload, but Test occurs with Upload in practice. Incorrect flow.
* C:Distribute before Upload is impossible-members need the file first. Incorrect.
* D:Test after Upgrade defeats the purpose of pre-validation. Incorrect.
* Practical Example:In an INE lab, you'd upload/test NIOS 8.6.2, distribute to an HA pair, upgrade the passive node, and troubleshoot sync issues, mastering Grid deployment.References:Infoblox NIOS Administrator Guide - Upgrade Process; INE Course Content: NIOS DDI Grid Deployment.

NEW QUESTION # 48
A superuser can change the password on another admin account.

A. True
B. False

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:In NIOS, asuperuseris an admin with unrestricted permissions across the Grid, including user management. Here's the breakdown:
* Superuser Role:Defined in Grid Manager (Administration > Administrators), superusers have full read
/write access to all objects and settings, including admin accounts.
* Password Change:A superuser can navigate to Administration > Administrators, select another admin account (e.g., "user1"), and modify its password, overriding any restrictions on that account.
* Why True:This is a built-in capability to ensure ultimate control, useful for scenarios like account recovery or security enforcement. No restrictions apply to superusers for this action.
* Practical Example:In an INE troubleshooting lab, a superuser might reset a locked-out admin's password to regain Grid access, testing authentication policies.
* Contrast:Regular admins with limited permissions can't modify others' accounts unless explicitly granted.References:Infoblox NIOS Administrator Guide - Admin Management; INE Course Objective: NIOS DDI Grid Deployment.

NEW QUESTION # 49
Which of the following statements about restarting Grid services are true? (Select all that apply.)

A. By default, the Grid restarts services every day
B. You can schedule service restarts
C. You can force service restart on a member
D. You can poll members to see which services will be restarted

Answer: B,C

Explanation:
Comprehensive and Detailed In-Depth Explanation:Restarting services (e.g., DNS, DHCP) on NIOS Grid members is a common administrative task, often required after configuration changes. Let's break down each option with detailed reasoning:
* A:"Poll members to see which services will be restarted" suggests proactively querying members for restart eligibility. NIOS doesn't offer a specific polling feature for this-administrators check service status (e.g., via Grid Manager > Members > Services) or logs, but there's no pre-restart polling tool.
Incorrect.
* B:In Grid Manager (Grid > Grid Manager > Members), you can select a member and click "Restart Services" with a "Force Restart" option, overriding any checks for necessity. This is useful in troubleshooting (e.g., clearing a hung DNS service). Correct.
* C:NIOS allows scheduling service restarts via the "Schedule Restart" option in Grid Manager, letting you specify a time to minimize disruption (e.g., off-hours). This aligns with Grid management best practices taught in INE. Correct.
* D:There's no default daily restart policy in NIOS. Restarts occur only when triggered by an admin or system event (e.g., upgrade). This would disrupt service unnecessarily if true. Incorrect.
* Practical Example:During an INE lab, you might force a restart on a member to resolve a DHCP failover issue or schedule a restart after updating a DNS zone to ensure propagation, reflecting real- world Grid troubleshooting.References:Infoblox NIOS Administrator Guide - Managing Grid Services; INE Course Content: NIOS DDI Grid Troubleshooting.
