A field engineer is onsite to replace a failed hot-swappable Power Supply Unit (PSU) in a DS224C disk shelf that is part of a production AFF A250 system. The system must remain online during the procedure. After physically identifying the failed PSU by its amber fault LED, what is the correct next step to ensure a safe and non-disruptive replacement?
An administrator reports that a node in an AFF A400 cluster is unable to achieve cluster quorum after an unscheduled reboot. The other nodes in the cluster are healthy. The `cluster show` command output indicates the node is unhealthy and cannot communicate with its peers. Which TWO of the following are the most likely causes for this issue? (Select TWO).
An administrator needs to collect detailed, real-time performance statistics for a specific LUN named 'SQL_LUN_01' that is reportedly experiencing high latency. The goal is to view the IOPS, throughput, and latency broken down by read, write, and other operations. Which command should the administrator use?
A financial services company runs a mixed workload on a single SVM hosted on a FAS8300 cluster running ONTAP 9.12.1. The IT department has received complaints about poor performance from users accessing SMB shares. Simultaneously, an automated NFS-based data ingestion process runs on the same SVM. A network administrator confirms there are no dropped packets on the switches connecting the storage to the clients. A junior storage administrator provides the following details: - The SVM has a single data LIF serving both SMB and NFS traffic. - The LIF is part of a single-port interface group using port e0c. - The NFS data ingestion workload is known to be very aggressive, often saturating the network link. - EMS logs show frequent messages indicating that the `gNFS_Ex` QoS policy, which has no throughput limit, is being used by the NFS clients. - SMB clients are not governed by any specific QoS policy. What is the most likely cause of the poor SMB performance? ```mermaid graph TD subgraph Corporate Network SMB_Clients[SMB Clients] --> Switch NFS_Client[NFS Data Ingestion Client] --> Switch end subgraph FAS8300 Cluster Switch --> e0c[Port e0c] e0c --> LACP[ifgrp a0a] LACP --> DataLIF[Data LIF: 192.168.10.100] DataLIF --> SVM end SVM -- Serves --> SMB_Share[SMB Share] SVM -- Serves --> NFS_Export[NFS Export] NFS_Client -- Aggressive Traffic --> NFS_Export SMB_Clients -- Slow Access --> SMB_Share ```
True or False: During an unplanned takeover in a NetApp HA pair, the surviving node replays the contents of its local NVLOG to commit writes that were in-flight on the failed node.
A support engineer must configure an export-policy rule for an NFSv4.1 export that enforces Kerberos 5p (krb5p) security for all client access. The policy should deny access to any client not using krb5p. Which configuration is correct?
A support engineer has booted a node into maintenance mode to troubleshoot a boot failure. To verify the contents of the boot device, the engineer needs to list the directories at the root of the file system. Which command should be used? `ls /________`
During routine maintenance on a FAS8700 controller, an amber fault light illuminates on the NVMEM/NVRAM battery. The controller is part of an active HA pair and must not be taken offline. What is the correct high-level procedure to replace the battery non-disruptively?
A support engineer is analyzing an AutoSupport bundle to diagnose the root cause of a system panic that generated a kernel core dump. The panic string references a memory parity error. Which TWO sections of the AutoSupport bundle are most critical for this investigation? (Select TWO).
A disk in a 12-drive RAID-TEC aggregate fails and is replaced. During the subsequent RAID reconstruction process, a second disk within the same RAID group also fails. What will be the resulting state of the aggregate?
