質問 # 22
A customer wants to have their MetroCluster IP automatically switch over in the event of a site disaster.
Which two NetApp features can the customer use to automate switchover? (Choose two.)
- A. Active IQ Unified Manager
- B. ONTAP Mediator service
- C. BlueXP observability
- D. MetroCluster TieBreaker
- E. Data Broker
正解：B
解説：
Explanation
= The ONTAP Mediator service and the MetroCluster TieBreaker are two NetApp features that can be used to automate switchover in a MetroCluster IP configuration in the event of a site disaster. The ONTAP Mediator service is a software component that monitors the health and connectivity of the MetroCluster nodes and initiates a switchover when it detects a failure of one site or a network partition between the sites. The MetroCluster TieBreaker is a software component that runs on a third site and acts as a quorum witness for the MetroCluster configuration. The MetroCluster TieBreaker prevents split-brain scenarios and enables automatic switchover when one site becomes unavailable or isolated. References = ONTAP Mediator service overview,

質問 # 23
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?
- A. 0
- B. 1
- C. 2
- D. 3
正解：D
解説：
Explanation
= 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 thereare more IPSpaces or a different network topology, the number of intercluster LIFs may vary. References = What is an Intercluster network?, Create intercluster LIFs (Beginning with ONTAP
