What are three volume-level storage efficiency features of ONTAP? (Choose three.)

• A.deswizzle
• B.space reclamation
• C.deduplication
• D.compression
• E.compaction

A customer has an aggregate, aggr1_01 with three RAID groups: rg0, rg1, and rg2.
Each RAID group has 15 disks, and the aggregate's maximum RAID group size is set to 18 disks.
The customer adds three additional disks to the aggregate using the following command: storage aggregate add-disks -aggregate aggr1_01 -diskcount 3 How are the RAID groups affected by this command?

• A.The three disks are added to RAID group rg0.
• B.Each RAID group receives one additional disk.
• C.The disks are added to a new RAID group rg3.
• D.The three disks are added to RAID group rg2.

What is a characteristic of a single-node cluster?

• A.It does not have a node management LIF.
• B.It only hosts a single SVM.
• C.It is unsupported in a production environment.
• D.It does not have any cluster interconnect LIFs.

Click the Exhibit button.

You have a 2-node NetApp cluster. You perform a storage failover and notice that IP address 10.1.100.21 is unreachable while omegana1-01 is rebooting. After omegana1-01 is back online, the IP address becomes reachable again. However, IP address 10.1.100.20 was still reachable during the reboot. The commands shown in the exhibit were executed before the storage failover.
In this scenario, why was IP address 10.1.100.21 unreachable?

• A.The failover group for 10.1.100.21 is misconfigured.
• B.The Address Resolution Protocol (ARP) cache needs to be cleared on the upstream switch.
• C.The node management LIFs cannot fail over to other nodes.
• D.The LIF for 10.1.100.21 has an incorrect failover setting.

You are receiving reports of high storage latency from the database administrators.
The NetApp storage system is connected to the network using 10 Gb. You run the sysstat command as shown in the exhibit.
In this scenario, why is storage latency high?

• A.The system is experiencing a disk bottleneck.
• B.The network interfaces are maximized out.
• C.The system does not have enough cache.
• D.The CPU usage is too high.
