質問 # 30
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 20% full.
- B. ONTAP reports that the volume Is using 100 GB of its containing aggregate.
- C. ONTAP reports the volume as 10% full.
- D. ONTAP reports that the volume Is using 10 GB of Its containing aggregate.
正解：C、D
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

質問 # 35
Which two storage efficiencies are enabled by default on NetApp AFF systems? (Choose two.)
- A. Inline deduplication
- B. Inline compression
- C. postprocess zero block detection
- D. postprocess compaction
正解：A、B
解説：
Explanation
To find out which two storage efficiencies are enabled by default on NetApp AFF systems, you need to look at the documentation that explains the inline storage efficiency enablement on AFF systems. According to this document1, the following storage efficiency features are enabled by default on all newly created volumes on AFF systems:
Inline compression: This feature reduces the amount of data written to disk by compressing data blocks before they are written to disk. Compression can reduce the storage space required by up to 50% or more, depending on the data type and compressibility.
Inline deduplication: This feature eliminates duplicate data blocks within a volume before they are written to disk. Deduplication can reduce the storage space required by up to 90% or more, depending on the data type and similarity.
You do not need to enable postprocess compaction or postprocess zero block detection on AFF systems, as they are not supported or required for SSDs. Postprocess compaction is a feature that combines multiple small data blocks into a single larger block after they are written to disk, which can reduce the storage space required by up to 30% or more. However, this feature is only supported for HDDs, as SSDs do not have the same physical limitations as HDDs. Postprocess zero block detection is a feature that identifies and removes blocks that contain only zeros after they are written to disk, which can reduce the storage space required by up to 10% or more. However, this feature is not required for SSDs, as inline zero block detection is already enabled by default on AFF systems23.

質問 # 44
Which two statements are true about NVMe? (Choose two.)
- A. Namespaces are mapped to subsystems.
- B. LUNs are mapped to Initiator groups.
- C. NQNs are added to subsystems.
- D. NQNs are added to namespaces.
正解：A、C
解説：
Explanation
NVMe is a protocol that enables fast and efficient access to storage devices over a network. NVMe uses NVM Express over Fabrics (NVMe-oF) to transport commands and data between hosts and storage systems.
NVMe-oF uses NVM subsystems, which are logical containers for one or more NVMe namespaces. A namespace is a logical unit of storage that can be accessed by a host. A host can discover and connect to an NVM subsystem by using a unique NVM subsystem identifier (NQN). ONTAP supports NVMe/FC and NVMe/RoCE as the transport protocols for NVMe-oF. ONTAP maps NVMe namespaces to LUNs and NQNs to subsystems. ONTAP also maps initiator groups to subsystems to control host access to namespaces.

質問 # 45
Windows 2019 reports 500 GB of free space on a disk; however, on the storage side, the LUN has 0 bytes free. When the host deletes files on the disk, auto reclaim on the thin-provisioned LUN does not occur.
In this scenario, which action should you take to enable space reclamation?
- A. Enable space guarantees on the volume.
- B. Set the space allocation option to disable.
- C. Set the space allocation option to enable.
- D. Enable space guarantees on the LUN.
正解：C
質問 # 46
Exhibit.
A user cannot save a file on an ONTAP SMB share.
Referring to the exhibit, which action allows the user to save the file?
- A. Synchronize the ONTAP Cluster time to the Active Directory time.
- B. Set the user permission for the share to write.
- C. Let the user save the file to a writeable location.
- D. Allow the file type, file In the CIFS Server policy.
正解：B
解説：
Explanation
The error message in the exhibit indicates that access to a specific file was denied. This is typically due to insufficient permissions. By setting the user's permission for the share to write, it would allow them to save files on that share.

質問 # 49
What establishes a quorum in a 4-node cluster?
- A. cluster peer
- B. ONTAP Mediator
- C. TieBreaker
- D. epsilon
正解：D
解説：
Explanation
Quorum is a measure of cluster health and function that indicates how clusters address potential communications and connectivity issues. Quorum is maintained by a simple majority of nodes that are healthy and can communicate with each other. In a 4-node cluster, there is a possibility of a tie in the number of nodes that can communicate with each other. To avoid this, one node has an extra fractional voting weight called epsilon. Epsilon is a tie breaker that helps the cluster decide which node will maintain the master copy of the replicated databases (RDB). The node with epsilon will always be part of the quorum, unless it is unhealthy or isolated. References :- About quorum and epsilon, What is Cluster HA and how is Epsilon utilized to maintain RDB Quorum?
