質問 # 41
A node has failed.
Which two conditions must be met for an automatic takeover to be triggered? (Choose two.)
正解：A、C
解説：
For an automatic takeover to occur in an HA pair, the following conditions must be met:
* The HA pair uses mailbox disks to coordinate and ensure that both nodes have consistent cluster state information.
* If the mailbox disks are not reachable, the takeover process cannot proceed.
1. Mailbox Disks Must Be Reachable:
* The nodes in an HA pair continuously mirror NVRAM data to ensure that writes are protected.
* If NVRAM is not synchronized, the takeover cannot safely handle active workloads.
2. NVRAM Must Be Synchronized:
* A. The combined utilization of both nodes must be less than 100%:
* This is not a requirement for automatic takeover. ONTAP can handle higher utilization during failover scenarios.
* B. The cluster network must be available:
* While the cluster network is critical for normal operation, takeover can still occur if the cluster network is unavailable, as long as the HA interconnect is operational.
Why Other Options Are Incorrect:
* NetApp "ONTAP High Availability Guide" outlines the requirements for automatic takeover in HA pairs.
* "ONTAP NVRAM Synchronization and Failover Guide" explains NVRAM mirroring requirements.

質問 # 42
A SAS connection is reporting a single PHY down.
What are the two most likely causes? (Choose two.)
正解：A、B
解説：
Understanding a Single PHY Down Issue:
* In SAS environments, a PHY represents a physical layer connection between devices.
* When a single PHY reports a "down" status, it typically indicates an issue with the physical connectivity or the associated hardware.
Cause 1: Improperly Seated Cable
* If the SAS cable is not properly seated in the port, the connection for one or more PHYs may fail.
* Reseating the cable on both ends (controller and shelf) often resolves the issue.
Cause 2: Defective Cable
* A damaged or faulty SAS cable can cause PHY errors.
* Replacing the cable and verifying the connection resolves the issue in this case.
Why Other Options Are Not Likely:
* B. Outdated IOM firmware: While outdated firmware can cause other issues, it rarely affects only a single PHY.
* D. Offline shelf: If an entire shelf is offline, more than one PHY would typically be affected, as multiple connections are involved in SAS stacks.
NetApp Reference Documentation:
* Found in the "ONTAP SAS Cabling Guide" and "Shelf Troubleshooting Guide". These documents detail troubleshooting for PHY errors and common SAS hardware issues.
質問 # 43
Which two factors can increase the chances of experiencing a NetApp WAFL inconsistency on an aggregate?
(Choose two.)
正解：A、B
解説：
* A. Ignoring NetApp Active IQ health risks
* Explanation:NetApp Active IQ provides proactive monitoring and alerts for system health risks, including risks related to WAFL inconsistencies. Ignoring these alerts can lead to unresolved issues such as metadata corruption, hardware failures, or system misconfigurations, increasing the chances of WAFL inconsistencies.
* Examples of Active IQ Risks:
* Disk health warnings.
* High write latency or metadata bottlenecks.
* Aggregates running out of space.
* C. Using outdated disk firmware
* Explanation:Outdated disk firmware can cause performance issues, drive failures, or incorrect handling of I/O operations, potentially leading to WAFL inconsistencies. Disk firmware updates often include fixes for critical issues that improve reliability and prevent data corruption.
* Importance:Keeping firmware updated ensures compatibility with ONTAP and minimizes risks of disk-level errors that can propagate to WAFL.
Why the Other Options Are Incorrect:
* B. Constantly running at high load:
* Running at high load can impact performance but does not directly cause WAFL inconsistencies.
WAFL is designed to handle high I/O loads efficiently.
* D. Upgrading frequently:
* Frequent upgrades, when performed correctly, do not increase the chances of WAFL inconsistencies. However, improperly executed upgrades or skipping recommended steps might introduce risks.
References:
* NetApp Knowledge Base: Articles on Active IQ health checks and disk firmware management.
* ONTAP System Administration Guide: Recommendations for preventing WAFL inconsistencies.
質問 # 44
Which RAID type provides protection against three disk failures?
正解：D
解説：
RAID-TEC Overview:
* RAID-TEC (Triple Erasure Coding) is a NetApp RAID technology designed to protect against up to three simultaneous disk failures.
* It is ideal for systems with high-density disks or workloads requiring extreme fault tolerance.
Why RAID-TEC Is Correct:
* RAID-TEC uses triple-parity protection, which provides redundancy against three disk failures, making it more resilient than RAID-DP or RAID 5.
* RAID-DP only protects against two disk failures, while RAID 4 and RAID 5 protect against a single failure.
NetApp Reference Documentation:
* "NetApp RAID and Data Protection Guide" details the differences between RAID-DP and RAID-TEC, highlighting RAID-TEC's ability to tolerate three failures.
質問 # 45
What is the recommended value for disk and CPU use when you plan an upgrade?
正解：D
解説：
Upgrade Considerations for Disk and CPU Utilization:
* During an ONTAP upgrade, it is critical to ensure the system has sufficient resources to handle the upgrade process without impacting normal operations.
Recommended Threshold:
* NetApp recommends that both disk and CPU utilization should be below 70% before initiating an upgrade. This ensures that there is enough headroom for the upgrade operations and avoids performance degradation.
Steps to Verify Utilization:
* Use the system node show -fields cpu command to check CPU usage.
* Use the storage aggregate show -fields used command to check aggregate disk utilization.
NetApp Reference Documentation:
* "ONTAP Upgrade and Maintenance Guide" specifies the 70% threshold for disk and CPU usage during upgrade planning.
* The "ONTAP Performance Management Guide" provides methods for monitoring system resource utilization.
