Question No. 2

A storage administrator is configuring a new 4-node AFF A400 ONTAP cluster. The cluster uses SnapMirror replication and provisions FlexCache origin volumes. The aggregates also use NetApp BlueXP tiering to object storage.

What is the minimum number of intercluster LIFs that are required on this cluster?

Show Answer Hide Answer
Correct Answer: C

= Intercluster LIFs are logical interfaces that enable communication between clusters for data replication and caching. The minimum number of intercluster LIFs required on a cluster depends on the number of nodes, the number of IPSpaces, and the network topology. According to the NetApp documentation, the following are the requirements for intercluster LIFs:

At least one intercluster LIF must be configured on every node in the local cluster, and on every node in the remote cluster. Provisioning intercluster LIFs on only some nodes of the cluster is not supported.

Each intercluster LIF requires an IP address dedicated for intercluster communication. The IP addresses assigned to intercluster LIFs can reside in the same subnet as data LIFs or in a different subnet.

Every intercluster LIF on every node of the local cluster should be able to connect to every intercluster LIF on every node of the remote cluster. The cluster peering topology should use full-mesh connectivity. Full-mesh connectivity means that all the Intercluster LIFs of one peer cluster can communicate with all of the Intercluster LIFs of the other peer cluster.

Based on these requirements, the minimum number of intercluster LIFs required on a 4-node cluster is 8, assuming that there is only one IPspace and a full-mesh network topology. This means that each node has one intercluster LIF that can connect to the intercluster LIFs of the other nodes in the same cluster and the remote cluster. If there are more IPSpaces or a different network topology, the number of intercluster LIFs may vary.Reference=What is an Intercluster network?,Create intercluster LIFs (Beginning with ONTAP 9.3),Create intercluster interfaces on all nodes (ONTAP 9.2 or earlier)


Question No. 5

What are two benefits of configuring Advanced Disk Partitioning (ADP) on an AFF or FAS system? (Choose two.)

Show Answer Hide Answer
Correct Answer: B, C

Advanced Disk Partitioning (ADP) is a feature that enables ONTAP to partition a disk into multiple logical units and use them for different purposes. ADP has two main benefits for AFF or FAS systems:

It optimizes storage capacity by reducing the number of disks required for the root aggregates, which store the system and configuration data. By using ADP, the root aggregate can share the same disk with a data aggregate, which stores the user data. This frees up more disks for data aggregates and increases the usable space for data.

It reduces RAID parity overhead by creating smaller RAID groups with partitions instead of whole disks. This reduces the amount of parity data that needs to be written and read, which improves the performance and efficiency of the system.Reference=What are the rules for Advanced Disk Partitioning?,Considerations for automatic drive assignment and ADP systems in ONTAP 9.4 and later,NetApp AFF and Advanced Drive Partition v2, part 1
