Infoblox Qualified NIOS DDI Expert - INE Sample Questions (Q25-Q30):

NEW QUESTION # 25
What is the correct order of a NIOS upgrade?

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

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 # 26
A customer reports difficulty joining a standalone High Availability (HA) pair. How should the customer diagnose the issue? Choose 2 answers

  • A. Use traffic capture on both nodes
  • B. Reset everything before trying to re-join
  • C. Use traffic capture on the first node (the active node)
  • D. Use error messages recorded in syslog and debug log on both nodes

Answer: A,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:Joining a standalone HA pair to a Grid involves network, authentication, and sync issues. Best diagnostics:
* A:Syslog (show log syslog) and debug logs (e.g., infoblox.log in support bundle) on both nodes reveal errors (e.g., "Join failed: invalid secret"). Essential for root cause. Correct.
* C:Traffic capture (tcpdump via CLI) on both nodes checks VRRP, bloxSync, and network issues (e.g., blocked ports). Comprehensive view of communication. Correct.
* B:Capturing only the active node misses passive node issues (e.g., firewall blocking sync). Incomplete.
Incorrect.
* D:Resetting erases logs and configs, hindering diagnosis-last resort, not initial step. Incorrect.
* Practical Example:In an INE lab, you'd check syslog for "sync failed," run tcpdump -i eth0 port 443 on both, and troubleshoot a blocked SSL port.References:Infoblox NIOS Administrator Guide - HA Troubleshooting; INE Course Content: NIOS DDI Grid Troubleshooting.


NEW QUESTION # 27
What can an administrator do with an Option Filter in NIOS?

  • A. Match on any DHCP options provided by the client
  • B. Match on any DHCP options provided by the server
  • C. Match only vendor-specific options such as Option 60
  • D. Match only on device types

Answer: A

Explanation:
Comprehensive and Detailed In-Depth Explanation:In NIOS, DHCP Option Filters allow administrators to define rules for matching DHCP client requests based on the options they send in their DHCP packets. These filters are highly flexible and can matchany DHCP option provided by the client, such as Option 55 (Parameter Request List), Option 60 (Vendor Class Identifier), or custom options. This enables precise DHCP policy enforcement, like assigning specific IP ranges or options to certain devices. Option B is incorrect because filters apply to client requests, not server responses. Option C is too narrow-while Option 60 is common, filters aren't limited to vendor-specific options. Option D is vague and incorrect; device type matching is a subset of option matching. The INE course covers DHCP troubleshooting, including filter configuration.References:Infoblox NIOS Administrator Guide - DHCP Option Filters; INE Course Content:
NIOS DDI DHCP Troubleshooting.


NEW QUESTION # 28
What sends the email messages for Workflow Approval notifications in NIOS?

  • A. NIOS Grid Master Candidate (GMC)
  • B. NIOS Grid Master (GM)
  • C. NIOS SuperAdmin
  • D. NIOS Grid Master (GM) and the NIOS Grid Master Candidate (GMC)

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:Workflow Approval notifications:
* A:The Grid Master (GM) sends emails via its configured SMTP settings (Grid > Grid Properties > Email), as it manages Grid-wide tasks. Correct.
* B:GMC is a standby, not active unless promoted-doesn't send emails. Incorrect.
* C:Only GM sends, not both-GMC is passive. Incorrect.
* D:SuperAdmin is a role, not a process-no sending capability. Incorrect.
* Practical Example:In an INE lab, configure SMTP on the GM, test approval emails, and troubleshoot delivery from GM logs.References:Infoblox NIOS Administrator Guide - Workflow Notifications; INE Course Objective: NIOS DDI Grid Deployment.


NEW QUESTION # 29
When configuring Authentication Policy, an administrator should always choose a group for "Assign users to this group if remote admin group cannot be found".

  • A. True
  • B. False

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:The Authentication Policy in NIOS (Administration > Authentication) governs remote authentication (e.g., LDAP, RADIUS). The "Assign users to this group if remote admin group cannot be found" option is a fallback mechanism:
* Purpose:If a user's remote group (e.g., from AD) isn't mapped to an NIOS group, this setting assigns them to a default group with predefined permissions.
* Requirement:It's optional-not mandatory. Leaving it unset means unmatched users are denied access unless individually mapped, enhancing security in some cases.
* Why False:"Always" implies it's required, but NIOS allows flexibility. For strict environments, admins might skip this to prevent unauthorized access, relying on explicit mappings.
* Options Analysis:
* A:Suggests a mandatory setting, but documentation and UI show it's a choice. Incorrect.
* B:Correctly reflects that it's not always necessary-optional based on policy. Correct.
* Practical Example:In an INE lab, you'd configure LDAP without a fallback group, test an unmapped user's denial, and troubleshoot authentication logs, reinforcing Grid security concepts.References:
