Question 6 of 60
You want to move a SAN LIF and preserve its configuration information and avoid rezoning the switch fabric.
In this scenario, which two steps must be performed to fulfill this goal? (Choose two.)
In this scenario, which two steps must be performed to fulfill this goal? (Choose two.)
Correct Answer: B, D
To successfully move a SAN LIF and preserve its configuration information while avoiding rezoning the switch fabric, the following steps must be performed: First, take the SAN LIF offline before it is moved. This ensures that no data corruption or connectivity issues occur during the move. Second, move the SAN LIFs to another node in a cluster on existing storage virtual machines (SVMs). This helps to maintain the existing configurations and relationships of the LIFs, thus preserving its configuration information and avoiding the need for rezoning.

Your customer asks you how to connect a host for SAN access to the newly installed AFF A400 system.
In this scenario, which two statements are correct? (Choose two.)
In this scenario, which two statements are correct? (Choose two.)
Correct Answer: C, D
Direct connection to the nodes from the hosts with iSCSI is supported because it is a common practice to use iSCSI for direct host connections in many storage environments. Similarly, direct connection to the nodes from the hosts with FC (Fibre Channel) is also supported, as many enterprise SAN environments use FC for direct connections due to its performance and reliability.

Click the Exhibit button.
In an NVMe/FC environment, the host cannot discover the namespace on the AFF system.
Referring to the exhibit, what is the problem?
In an NVMe/FC environment, the host cannot discover the namespace on the AFF system.
Referring to the exhibit, what is the problem?
Correct Answer: A
The problem is that the NQN (NVMe Qualified Name) is not correct. In the exhibit, the NQN shown by the command 'vserver nvme subsystem host show' does not match the NQN found in the file '/etc/nvme/hostnqn'. For the host to discover the namespaces correctly, the NQN on the host must match the NQN configured on the storage system.
Question 9 of 60
You are designing a new 4-node AFF A400 SAN cluster with 20 iSCSI hosts. Each AFF A400 node will have four data LIFs. Each iSCSI host needs to access every LUN over two LIFs per node on every SAN node.
In this scenario, which NetApp SAN feature enables this connectivity?
In this scenario, which NetApp SAN feature enables this connectivity?
Correct Answer: B
To enable each iSCSI host to access every LUN over specific LIFs per node in a NetApp SAN environment, the feature to use is 'port sets'. Port sets allow you to limit the number of paths to a LUN by specifying which target ports can be used by initiators. This enables efficient management of LUN access and helps in balancing the load across the available network interfaces.
Question 10 of 60
You are planning on implementing a new SAN on AFF A400 controllers. The data set consists of unique 1 KB files that will be encrypted before being written to the SAN.
In this scenario, which ONTAP inline storage efficiency will provide 4:1 savings for this workload?
In this scenario, which ONTAP inline storage efficiency will provide 4:1 savings for this workload?
Correct Answer: D
In this scenario, compaction is the correct ONTAP inline storage efficiency feature for achieving 4:1 savings on a workload consisting of unique 1 KB files that will be encrypted. Compaction works by reducing the amount of physical storage required by aggregating smaller data chunks into a single storage block, thus optimizing storage usage. This is particularly effective with small file sizes such as 1 KB, enabling substantial space savings.
