[netapp-ct1: cp_worker: wafl.cp.toolong:error]: Aggregate AG1_NTAP_PROD experienced a long CP.
Tue Jun 27 18:37:10 CEST
Which two data sources do you use to explain this message? (Choose two.)
- A . ONTAP System Manager
- B . Performance Archive
- C . Active IQ Unified Manager
- D . mgwd.log
A,C
Explanation:
To explain the message in the EMS logs indicating that the aggregate AG1_NTAP_PROD experienced a long Consistency Point (CP), the two most relevant data sources would be:
ONTAP System Manager – This is a graphical management interface for NetApp ONTAP storage systems. It can provide insights into the performance and health of the aggregates, including detailed information about operations like CPs. Using ONTAP System Manager, you can investigate the performance metrics of the aggregate in question to understand why a long CP occurred.
Active IQ Unified Manager – This tool provides comprehensive monitoring and reporting for NetApp storage systems. It can be used to analyze historical data and trends in system performance, which can help to understand the context and potential causes of the long CP observed in the EMS log.
Several clients are accessing an ONTAP SnapMirror DP destination volume. Some clients frequently access the newest SnapMirror volume data. Accessing this data is much slower when compared to clients that directly access data on the source. You use the wafl scan status command against the destination.
What is a symptom of the problem in this scenario?
- A . blocks used summary update
- B . active bitmap rearrangement
- C . container block reclamation
- D . volume deswizzling
D
Explanation:
In the scenario described, where clients are experiencing slower access to the newest data on an ONTAP SnapMirror Data Protection (DP) destination volume compared to direct access on the source, and considering the use of the wafl scan status command against the destination, a likely symptom of the problem could be:
volume deswizzling – Deswizzling is a process that occurs when data is read from a SnapMirror destination volume. In a SnapMirror relationship, data is stored in a "swizzled" format, which is efficient for replication but needs to be converted ("deswizzled") back for regular access. If a lot of deswizzling is happening, it could contribute to slower access times for clients accessing the newest data on the destination volume.
What is the consequence of a loss of connectivity between a Cloud Volumes ONTAP (CVO) instance and Cloud Manager for four or more days?

- C . Cloud Manager removes the CVO instance from its inventory.
- D . The CVO instance is stopped.
You want to use the supported method to upgrade the ONTAP version of a Cloud Volumes ONTAP instance from ONTAP 9.5 to ONTAP 9.6.
In this scenario, which NetApp tool accomplishes this task?
- A . Cloud Manager
- B . Cloud Insights
- C . Active IQ Unified Manager
- D . ONTAP System Manager
A
Explanation:
In this scenario, to upgrade the ONTAP version of a Cloud Volumes ONTAP (CVO) instance from ONTAP 9.5 to ONTAP 9.6, the appropriate NetApp tool to use is:
Cloud Manager – Cloud Manager is the tool designed for managing Cloud Volumes ONTAP instances. It provides the capabilities to upgrade the ONTAP software version on these instances. Using Cloud Manager, you can orchestrate the upgrade process in a guided and controlled manner, ensuring compatibility and minimizing disruption.
A customer must store physical hard copies of transaction data off site to meet regulatory requirements.
Which NetApp technology enables the customer to accomplish this task?
- A . SnapVault
- B . NDMP
- C . SVM DR
- D . FlexCache
B
Explanation:
To meet the regulatory requirement of storing physical hard copies of transaction data off-site, the appropriate NetApp technology for the customer to use would be:
NDMP (Network Data Management Protocol) – NDMP is a protocol used for the backup and recovery of data on network-attached storage (NAS) systems. It allows the customer to back up data from NetApp storage systems to tape or other physical media, which can then be stored off-site. This is suitable for creating physical hard copies of data for regulatory compliance.

What are two supported cabling methods for a NetApp HCI compute node? (Choose two.)
- A . 1-cable configuration
- B . 2-cable configuration
- C . 6-cable configuration
- D . 4-cable configuration
B,D
Explanation:
For a NetApp HCI compute node, two supported cabling methods include:
2-cable configuration – This setup involves using two cables, providing a balance between simplicity and connectivity. It typically includes connections for management and data traffic.
4-cable configuration – This cabling method uses four cables, providing additional bandwidth and potential redundancy. It allows for more connections, which can be beneficial for environments with higher network traffic or the need for separate networks for different types of traffic.
For testing purposes, your customer decides to use FC on a single-node ONTAP cluster. There is only one host that the customer expects to use. High availability is not a concern for this test. The customer connects the host directly to the ONTAP node. The LUN is set up, and the igroup is configured. When the customer tries to attach to the LUN from the host, the LUN is not seen by the host.
Which statement is correct in this scenario?
- A . Multipathing must be used and connected to another FC path.
- B . NPV must be enabled on the host before trying to attach to the LUN.
- C . NPIV must be enabled on the host before trying to attach to the LUN.
- D . An FC switch must be used with ONTAP.
What is the minimum number of compute nodes required to run the NetApp Deployment Engine for NetApp HCI?

You are working on a fabric MetroCluster. After a site failure, the plex starts to resync automatically to the aggregate mirror of Aggr1. The plex now shows a status of resyncing. During this process, you experience a slow resync of the SyncMirror plex.
In this scenario, how do you solve the problem?
- A . Add more disks to the aggregate to add more I/O capacity.
- B . Destroy and re-create plex, then run a baseline sync.
- C . Tune the resync speed by adding a QoS policy and limit the concurrent I/O to the aggregate.
- D . Tune the resync speed using the storage raid-options command.
D
Explanation:
In the scenario of experiencing a slow resync of the SyncMirror plex in a fabric MetroCluster environment, the following steps can be taken to address the problem:
Tune the resync speed using the storage raid-options command – This command allows you to adjust various RAID options, including parameters related to the resync process. By tuning these options, you can potentially increase the speed of the resync process, which can be particularly useful in a situation where the resync speed is slower than expected.
You have an ONTAP 2-node cluster. You run a read/write test workload against an SMB share, and it is slower than you expected. You run the same test again, but this time you monitor the storage using a QoS command.
Referring to the exhibit, what is the problem?
- A . There is a disk bottleneck.
- B . An HA interconnect problem is present.
- C . The SMB read sizes should be increased.
- D . The NVRAM needs to be replaced.
