最新的 DDI Professional NIOS-DDI-Expert 免費考試真題 (Q68-Q73):

問題 #68
The Grid is comprised of all single members. Which member will upgrade first?

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

答案：B

解題說明：
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.

問題 #69
Revert allows an administrator to swap the Infoblox software to the previously installed version of code, while retaining the current DNS, DHCP, and Grid configuration information.

A. False
B. True

答案：B

解題說明：
Comprehensive and Detailed In-Depth Explanation:The "Revert" feature in NIOS is a safety mechanism for software upgrades, allowing rollback to the prior version if issues arise. Here's how it works:
* Mechanism:NIOS retains the previous software version and configuration database after an upgrade.
The "Revert" option (Grid > Upgrade > Revert) swaps back to the old code, preserving the current DNS zones, DHCP leases, and Grid settings (e.g., member roles).
* Conditions:
* Revert is available only if the upgrade was successful and the prior version is still stored (not overwritten by multiple upgrades).
* Configuration changes made post-upgrade are kept, unlike a factory reset.
* Why True:This aligns with Infoblox's design to minimize downtime and data loss during version management, a key focus in INE's Grid troubleshooting labs.
* Counterpoint:If the database schema changes significantly between versions, some settings might not fully revert, but core DNS/DHCP/Grid data remains intact per documentation.
* Practical Example:After upgrading to NIOS 8.6.2 and encountering DNS issues, you'd revert to 8.6.1 in an INE lab, verifying that zone data persists for troubleshooting continuity.References:Infoblox NIOS Administrator Guide - Software Revert; INE Course Content: NIOS DDI Grid Troubleshooting.

問題 #70
What sends the email messages for Workflow Approval notifications in NIOS?

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

答案：B

解題說明：
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.

問題 #71
In the DHCPv4 failover NORMAL state, leases are only stored on the primary peer.

A. True
B. False

答案：B

解題說明：
Comprehensive and Detailed In-Depth Explanation:In NORMAL state:
* Lease Storage:Both primary and secondary peers store leases via sync (TCP 647). Each manages its pool share (e.g., 50/50), but all leases are replicated for redundancy.
* Why False:"Only primary" contradicts failover's design-both peers maintain a full lease database for failover readiness.
* Practical Example:In an INE lab, check leases on both peers (Data Management > DHCP > Leases), simulate primary failure, and troubleshoot secondary takeover.References:Infoblox NIOS Administrator Guide - DHCP Failover; INE Course Content: NIOS DDI DHCP Troubleshooting.

問題 #72
A Grid member in a DHCP Failover pair is in the PARTNER-DOWN state. What does this mean?

A. The member has lost contact with its peer
B. An administrator put the member in this state to indicate the member is down and the member's peer will take over
C. This member is malfunctioning and the member's peer must take over assignments
D. An administrator put the member in this state to indicate the member's peer is down

答案：D

解題說明：
Comprehensive and Detailed In-Depth Explanation:PARTNER-DOWN in DHCP Failover:
* B:Admin manually sets this state (Grid > DHCP > Failover > Edit) to signal the peer is down (e.g., powered off), giving the member full pool control. Correct.
* A:Loss of contact is COMMUNICATIONS-INTERRUPTED-PARTNER-DOWN is deliberate.
Incorrect.
* C:Indicates the member is down-opposite of intent. Incorrect.
* D:Malfunction implies automatic state-PARTNER-DOWN is manual. Incorrect.
* Practical Example:In an INE lab, set PARTNER-DOWN, verify full lease control, and troubleshoot sync resumption.References:Infoblox NIOS Administrator Guide - DHCP Failover States; INE Course Content: NIOS DDI DHCP Troubleshooting.
