True or False: In the event of a full site failure and subsequent switchover to the surviving site, unmirrored aggregates that existed on the failed site will automatically be brought online and made accessible by the surviving nodes.
Show answer details
Correct answer: B
False. Unmirrored aggregates do not have a secondary plex at the remote site. Therefore, if the site hosting the disks for an unmirrored aggregate fails, that data is completely inaccessible to the surviving site during a switchover.

In a MetroCluster IP configuration, how is the synchronous mirroring of NVRAM data handled between the High Availability (HA) partners across the two sites?
Show answer details
Correct answer: B
In MetroCluster IP, dedicated FC-VI adapters are not used. Instead, both storage traffic (iSCSI) and NVRAM mirroring traffic (using RDMA over Ethernet, such as iWARP or RoCE) share the same backend Ethernet switches.
- 3
When comparing a fabric-attached MetroCluster FC to a stretch MetroCluster FC, which TWO of the following statements accurately describe the fabric-attached architecture? (Select TWO)
Show answer details
Correct answer: A, C
Fabric-attached MetroCluster uses dedicated FC switches for the backend storage fabric, allowing for much greater distances (up to 300km) compared to stretch MetroCluster, which directly cables SAS or FC connections without a switched fabric.

A storage architect is planning a new MetroCluster IP deployment for a financial institution. Before purchasing the hardware, they must ensure that the selected Ethernet switches and ONTAP versions are officially supported for the backend interconnect. Which NetApp tool is specifically designed to validate these supported combinations?
Show answer details
Correct answer: C
The NetApp Interoperability Matrix Tool (IMT) is the definitive source for verifying supported combinations of ONTAP versions, MetroCluster topologies (FC or IP), and third-party backend switches (like Cisco or Broadcom). Hardware Universe (HWU) shows physical limits, and Config Advisor is used for post-cabling validation.
- 5
When planning the Inter-Switch Links (ISLs) for a MetroCluster IP solution across two data centers, specific network prerequisites must be met to ensure synchronous replication and cluster stability. Which TWO of the following are mandatory requirements for the ISL network? (Select TWO)
Show answer details
Correct answer: B, C
MetroCluster IP requires Layer 2 connectivity (not Layer 3) between the backend switches. The network path must support Jumbo Frames with an MTU size of at least 9216 bytes for RDMA traffic, and the maximum supported distance for MetroCluster IP is 700km, not 300km.

During the assessment phase for a new enterprise storage environment, a customer wants to know the maximum distance limits for a fabric-attached MetroCluster FC solution compared to a MetroCluster IP solution without using specialized long-distance optical amplifiers. Which tool should the engineer consult to find the precise physical distance limitations and latency requirements for specific ONTAP controller models?
Show answer details
Correct answer: C
The NetApp Hardware Universe (HWU) is the authoritative source for physical hardware limitations, including maximum supported ISL distances, node counts, and latency thresholds for specific controller models in both FC and IP MetroCluster configurations. IMT shows software/switch compatibility, not physical limits.
