Infoblox Qualified NIOS DDI Expert - INE Sample Questions (Q40-Q45):

NEW QUESTION # 40
How are Workflow Approval notifications delivered in NIOS?

A. Via SMS
B. Via email
C. Via push notifications
D. Via in-app notifications

Answer: B

Explanation:
Comprehensive and Detailed In-Depth Explanation:Workflow Approval in NIOS enforces change control with notifications:
* Mechanism:When a requester submits a change (e.g., new DNS record), approvers are notified via email, configured in Grid Properties (Grid > Grid Manager > Grid Properties > Email).
* Details:SMTP server settings (e.g., IP, port, credentials) must be defined for delivery. No other methods are natively supported.
* Options:
* A:SMS isn't supported-requires external integration. Incorrect.
* B:Push notifications aren't part of NIOS GUI or mobile app (none exists). Incorrect.
* C:Email is the documented, sole method. Correct.
* D:In-app notifications don't exist-Grid Manager relies on email. Incorrect.
* Practical Example:In an INE lab, you'd configure an SMTP server, request a zone change, and troubleshoot email delivery failures for approval, testing Grid management.References:Infoblox NIOS Administrator Guide - Workflow Approval Notifications; INE Course Objective: NIOS DDI Grid Deployment.

NEW QUESTION # 41
By default, how do peers in an Infoblox DHCP Failover association operate in NORMAL mode?

A. The primary answers all lease requests
B. The primary answers all lease requests up to the utilization threshold, then the secondary answers requests
C. Whichever peer receives the request first will answer the request
D. The primary peer answers roughly half of the lease requests and the secondary answers the other half

Answer: D

Explanation:
Comprehensive and Detailed In-Depth Explanation:DHCP Failover in NIOS ensures redundancy and load balancing between primary and secondary peers in NORMAL mode:
* Default Behavior:The lease pool is split (typically 50/50 unless customized via "split" settings), and each peer manages its portion. Clients send DHCPDISCOVER broadcasts, and relays (or direct requests) distribute them to both peers. The peers coordinate via TCP 647, ensuring:
* Primary answers from its half.
* Secondary answers from its half.
* Load is roughly balanced (not precisely 50/50 due to relay behavior).
* Options:
* A:Matches the default split-pool design, where peers share the load. Correct.
* B:"First come, first serve" isn't how failover works-peers don't race; they use pool allocation.
Incorrect.
* C:No utilization threshold triggers a switch-both peers serve concurrently from their pools.
Incorrect.
* D:Primary-only answering defeats failover's redundancy and balancing. Incorrect.
* Practical Example:In an INE lab, you'd configure a 50/50 split, simulate client requests, and troubleshoot lease distribution via DHCP logs, verifying NORMAL mode behavior.References:

NEW QUESTION # 42
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 poll members to see which services will be restarted
C. You can schedule service restarts
D. You can force service restart on a member

Answer: C,D

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.

NEW QUESTION # 43
When controlling Grid Members under Grid > Grid Manager > Members, what control options are available from the Toolbar? Choose 3 answers

A. Restart GUI
B. Restart
C. Reboot
D. Suspend

Answer: B,C,D

Explanation:
Comprehensive and Detailed In-Depth Explanation:Grid Manager Toolbar (Grid > Members) offers member controls:
* A (Reboot):Reboots the appliance-full restart. Correct.
* B (Restart):Restarts services (e.g., DNS, DHCP) without reboot. Correct.
* C (Suspend):Pauses services-useful for maintenance. Correct.
* D:"Restart GUI" isn't a member-level option-GUI runs on GM, not per member. Incorrect.
* Practical Example:In an INE lab, reboot a member, restart services, suspend another, and troubleshoot impacts.References:Infoblox NIOS Administrator Guide - Member Controls; INE Course Content:
NIOS DDI Grid Troubleshooting.

NEW QUESTION # 44
What does VRRP stand for?

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

Answer: B

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.
