質問 # 41
Exhibit.
You have a 2-node NetApp FAS2750 ONTAP cluster. You create a new 20-GB LUN In a new 100-GB volume and write 10 GB of data to the LUN. No storage efficiencies are enabled for the volume or aggregate.
Referring to the exhibit, which two statements are true? (Choose two.)
- A. ONTAP reports the volume as 10% full.
- B. ONTAP reports that the volume Is using 10 GB of Its containing aggregate.
- C. ONTAP reports the volume as 20% full.
- D. ONTAP reports that the volume Is using 100 GB of its containing aggregate.
正解：A、B
解説：
Explanation
When a LUN has space reservations disabled (a non-space-reserved LUN), and its containing volume has no space guarantee, ONTAP reports the volume usage based on the actual data written to the LUN, not the LUN size. Therefore, ONTAP reports that the volume is using 10 GB of its containing aggregate, and the volume is
10% full. References :- Understanding space reservations for LUNs in System Manager, Recommended volume and file or LUN configuration combinations overview

Exhibit
You have Installed a new ONTAP 9.8 cluster and want to move the e0e and e0c ports into a new broadcast domain. Referring to the exhibit, which action satisfies this requirement?
- A. Use ONTAP System Manager to create a new broadcast domain.
- B. Use the broadcast-domainmerge command.
- C. Use the irrDadcast-domain create command
- D. Use the broadcast-domain split command.
正解：D
解説：
Explanation
The broadcast-domain split command allows you to create a new broadcast domain by moving one or more ports from an existing broadcast domain to the new one. In this scenario, you can use this command to move the e0e and e0c ports from the Default broadcast domain to a new broadcast domain in the same IPspace. This would satisfy the requirement of creating a new broadcast domain with the specified ports. The other options are not valid for this scenario, as they either create a new broadcast domain without moving any ports (A), merge two existing broadcast domains into one (D), or require a graphical user interface.

質問 # 46
After deploying an AFF A400, you want to deploy a storage virtual machine (SVM) to serve SMB data.
Which three conditions must exist in this scenario? (Choose three.)
- A. You must have sufficient space for the root volume.
- B. You must have a non-root aggregate in the online state.
- C. You must have encryption enabled on the root volume.
- D. You must have configured the export policies.
- E. You must synchronize the cluster time.
正解：A、B、E
解説：
Explanation
To deploy an SVM to serve SMB data, you must have sufficient space for the root volume, a non-root aggregate in the online state, and synchronize the cluster time. The root volume is the volume that contains the SVM configuration and metadata, and it must have enough space to accommodate the SVM growth1. The non-root aggregate is the aggregate that contains the data volumes that you will create and share using SMB2. The cluster time is the time that is synchronized across all nodes in the cluster, and it must be consistent with the Active Directory domain time to avoid authentication failures3. Encryption is not required on the root volume, asit does not store any user data. Export policies are not relevant for SMB access, as they are used to control NFS access4.

質問 # 47
A node fails on an HA configuration. A successful failover occurs, but your clients that are using the SMB protocol complain that they are not able to access their data.
In this scenario, what caused the problem?
- A. The disk ownership did not transfer correctly.
- B. One of the cluster Interconnect ports on the surviving node failed.
- C. The quota for the qtree has been reached.
- D. The surviving node is not licensed for CIFS.
正解：D
解説：
Explanation
CIFS is the NetApp implementation of the SMB protocol, which enables file sharing between Windows clients and NetApp storage systems. To use CIFS, the storage system must have a valid CIFS license installed and configured. If a node fails on an HA configuration, the surviving node takes over the resources and services of the failed node, including the CIFS server. However, if the surviving node does not have a CIFS license, the CIFS server cannot start and the clients cannot access their data. Therefore, the lack of CIFS license on the surviving node is a possible cause of the problem. References :- CIFS and SMB overview, Licensing overview, Troubleshooting CIFS issues Learn more

Referring to the exhibit, what is the problem?
- A. The volume is in read-only.
- B. The host IP address does not match the export policy rule.
- C. The volume is not mounted In the namespace.
- D. The logical Interface does not allow the NFSv3 protocol.
正解：C
解説：
The volume is not mounted in the namespace. https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.cdot-famg-nfs%2FGUID-8E400D78-B405-4682-8F33-143783F2D580.html Even if the volume was read only it could be mounted - also the client IP is in the desired range and LIF is configured for NFS.
質問 # 51
The source NAS volume of a SnapMirror relationship is unavailable due to networking issues at your organization's primary data center. You want to make the destination NAS volume writable so that clients are able to access their data.
Which two steps do you need to take to solve the issue? (Choose two.)
- A. Use the volume mount command to mount the NAS volume In the NFS namespace.
- B. Delete the SnapMirror relationship from the destination cluster.
- C. Break the SnapMirror relationship using the snapairrcr break command from the destination cluster.
- D. Break the SnapMirror relationship using the snapmirror break command from the source cluster.
正解：A、C
解説：
Explanation
To make the destination NAS volume writable, you need to break the SnapMirror relationship using the snapmirror break command from the destination cluster, and then use the volume mount command to mount the NAS volume in the NFS namespace. Breaking the SnapMirror relationship will make the destination volume read/write and allow clients to access the latest Snapshot copy. Mounting the volume in the NFS namespace will make the volume visible to the clients and enable them to access the data. The other options are not correct because:
Deleting the SnapMirror relationship from the destination cluster will not make the destination volume writable, but rather remove the relationship configuration and history. This will prevent future resynchronization or updates of the relationship.
Breaking the SnapMirror relationship using the snapmirror break command from the source cluster will not work, because the source cluster is unavailable due to networking issues. The command must be run from the destination cluster. References :- Break the SnapMirror relationship, Mount a volume in the namespace

質問 # 62
You are asked by your network engineering team to make sure that your NetApp cluster is configured to run LACP on Its network ports. Which network component satisfies this request?
- A. Interface group
- B. VLAN
- C. failover group
- D. broadcast domain
正解：A
解説：
Explanation
LACP (Link Aggregation Control Protocol) is a protocol that enables the bundling of several physical ports into a single logical port to provide higher bandwidth, load balancing, and redundancy. An interface group is a network component that supports LACP on NetApp clusters. An interface group can combine two or more physical ports into a single logical port and can be configured with different policies, such as multimode, multimode_lacp, or singlemode. A VLAN (Virtual Local Area Network) is a logical segmentation of a network that allows devices to communicate as if they were on the same physical network, regardless of their physical location. A broadcast domain is a logical division of a network in which all nodes can reach each other by broadcasting. A failover group is a set of network ports that can take over the traffic of another port in case of a failure.

質問 # 63
You are the administrator of an ONTAP 9.8 cluster. Your company wants to know how many files are In the NAS volumes of the cluster and how old these files are.
Which two tools fulfill this requirement? (Choose two.)
- A. ONTAP System Manager
- B. Active IQ Config Advisor
- C. Active IQ Unified Manager
- D. ONTAP CLI
正解：A、D
解説：
Explanation
To find out how many files are in the NAS volumes of the cluster and how old these files are, you can use the following two tools:
ONTAP System Manager 9.8 provides a way for admins to find out file system information in any NAS storage volume quickly and easily by enabling a low-impact scanner for each volume. This scanner crawls the ONTAP file system in the background with a low priority job and delivers a wealth of information that is available as soon as you navigate to the volume details page. You can see the file and directory count, the file-age histograms, the capacity use, and other parameters for each volume1.
ONTAP CLI provides the filestats command that can display a summary of file statistics within a volume on a storage system by reading the file information from a snapshot copy that you specify. You can use various options to filter the output by file size, file type, file age, and so on2.
Active IQ Config Advisor and Active IQ Unified Manager are not the tools that can fulfill this requirement, as they are mainly used for monitoring and managing the health, performance, and configuration of the cluster, not the file system details of the volumes34. References :- Active IQ Config Advisor, Active IQ Unified Manager, How to report file sizes within a volume using the filestats command, ONTAP 9.8 Feature Overview.
