When a two-node cluster is expanded, which cluster configuration would be supported?

  • A. a 4-node switched cluster
  • B. a 4-node switchless cluster
  • C. a 3-node switched cluster
  • D. a 3-node switchless cluster


Answer : C

Explanation:
If you are adding nodes to a two-node switchless cluster, you must have installed and configured the cluster management and interconnect switches before adding additional nodes.
The switchless cluster functionality is supported only in a two-node cluster.

You have a cluster of FAS controllers with HDD aggregates. The data is being compressed into 32 KB blocks before being written to a volume.
In this scenario, which type of compression is being used?

  • A. secondary, inline compression
  • B. adaptive, inline compression
  • C. adaptive, postprocess compression
  • D. secondary, postprocess compression


Answer : A

Explanation:
NetApp data compression reduces the physical capacity required to store data on storage systems by compressing data within a flexible volume (FlexVol volume) on primary, secondary, and archive storage. It compresses regular files, virtual local disks, and LUNs.
When NetApp data compression is configured for inline operation, data is compressed in memory before it is written to disk.

Which network interface failover group target ports are available when the system-defined failover policy is used?

  • A. only the ports in the failover group that are in the LIFs home node and on the LIFs storage-failover (SFO) partner node
  • B. only the ports in the failover group that are in the LIF’s home node
  • C. only the ports in the failover group that are in the LIFs home node and on a non- storage-failover (non-SFO) partner node
  • D. all network ports from all nodes in the failover group


Answer : C

Explanation:
system-defined: Only those ports on the LIF's home node and a non-SFO partner.

You manage a multi-tenant NetApp storage system. You start configuring an SVM for a new customer and receive the error shown in the exhibit when you attempt to create a LIF.
You verify that the IP address is correct and that the customer LIF does not already exist.
However, you see that another customer is using the same IP address in their SVM.
How would you correct this problem?

  • A. Create a new VLAN for the new customer.
  • B. Create the LIF with a different IP address.
  • C. Create an IPspace for the new customer.
  • D. Create a broadcast domain for the new customer.


Answer : C

Explanation:
The IPspace feature enables a single storage system to be accessed by clients from more than one disconnected network, even if those clients are using the same IP address.

  • C. Client access is being redirected to the destination location during this phase of the operation.
  • D. The cutover process failed and is in a holding pattern before being attempted again.
