NEW QUESTION # 101
A customer wants a NetApp ONTAP All SAN Array (ASA) cluster set up with a redundant Ethernet configuration.
What needs to be configured to achieve this?
Answer: D
Explanation:
IP SAN redundancy requires independent storage paths between each host and both nodes of the HA pair.
NetApp SAN networking guidance recommends creating multiple iSCSI paths from each node and specifically allows two data LIFs per node to provide connectivity through separate Ethernet networks. These networks should use separate IP subnets or ranges so that loss of one network, switch, port, or path does not eliminate host access to the storage. Host-side MPIO then uses the remaining paths during a failure. A node- management LIF provides administrative connectivity and is not a redundant data path. Selective LUN Mapping controls which cluster nodes report a LUN, while separate SVMs are not required merely to create network redundancy. Therefore, at least two data LIFs per node across separate IP networks provide the requested redundant Ethernet SAN configuration.
NEW QUESTION # 102
An engineer has just installed a new MetroCluster IP system for their SAN environment and wants to verify if all backend network connections are set up and working correctly.
Which two commands must the engineer run to verify the configuration? (Choose two.)
Answer: A,C
Explanation:
The engineer should first execute metrocluster check run to perform a current diagnostic validation of the MetroCluster configuration. NetApp documents that this command checks MetroCluster components and relationships and records any configuration errors. After the diagnostic completes, metrocluster check connection show displays the connection-specific results for MetroCluster IP nodes, including network connectivity checks and error information relating to ping, MTU, and storage connectivity. This directly addresses the requirement to verify backend network connections. metrocluster check cluster show focuses on cluster configuration results, while metrocluster check lif show focuses on LIF placement and related checks rather than the backend connections themselves. Relevant SAN ONTAP and MetroCluster topics include MetroCluster diagnostics, backend IP connectivity, configuration validation, inter-site connections, and post- installation verification.
NEW QUESTION # 103
An administrator is deploying a new SAN workload that has a NetApp All SAN Array (ASA) cluster. The customer wants to reclaim space by tiering to Azure Blob storage.
According to NetApp best practices, which volume tiering policy should be applied?
Answer: B
Explanation:
The Auto FabricPool tiering policy permits ONTAP to identify cold blocks in both the active filesystem and Snapshot data and move those blocks from the performance tier to the configured object-store capacity tier, including Microsoft Azure Blob Storage. Unlike the all policy, Auto does not immediately classify all blocks as cold; active data remains on the performance tier until it satisfies the cooling criteria. The default cooling period for Auto is 31 days and can be adjusted within supported limits. snapshot-only restricts tiering primarily to Snapshot-related blocks, while none prevents additional blocks from being tiered. Because the customer specifically wants to reclaim performance-tier capacity while retaining active SAN workload behavior, the Auto policy provides the appropriate balance between cloud-tier space reclamation and performance.
NEW QUESTION # 104
An engineer has a 100 GB volume with the space guarantee set to volume and fractional reserve set to 100.
The Snapshot reserve is disabled. The volume contains two 20 GB LUNs, and each LUN has the space guarantee enabled and is 50% full. The engineer creates a Snapshot copy of the volume, and no data is written or modified after the Snapshot copy is taken.
What is the available space in the volume?
Answer: C
Explanation:
The correct available capacity is 20 GB. Both 20 GB LUNs are space-reserved, so ONTAP reserves their full provisioned capacity rather than only the 10 GB currently consumed in each LUN. The two LUN reservations therefore account for 40 GB. Because the volume uses a 100% fractional reserve and a Snapshot copy exists, ONTAP also reserves sufficient overwrite space for 100% turnover of the reserved objects. That represents another 40 GB. Consequently, 80 GB of the 100 GB volume is committed: 40 GB for the two space-reserved LUNs and 40 GB to guarantee their overwrites. This leaves 20 GB available. NetApp describes fractional reserve 100 as reserving 100% of the space necessary for overwrites of reserved objects. Relevant topics include LUN space reservation, fractional reserve, thick provisioning, and Snapshot overwrite guarantees.
NEW QUESTION # 105
An administrator has a NetApp AFF cluster supporting an application with twelve LUNs allocated across four volumes. There is a requirement to configure a Snapshot copy of all LUNs simultaneously as a single unit.
Which NetApp ONTAP command should be used to configure this requirement?
Answer: D
Explanation:
To configure a Snapshot copy of all LUNs simultaneously as a single unit in an application with multiple LUNs spread across several volumes, the command vserver consistency-group create should be used. This command creates a consistency group that allows for coordinated snapshot creation across multiple volumes, ensuring that the snapshots are consistent with each other.
