Q17. You are setting up a LIF for the node management network.
What will be the default failover policy in this scenario?
A. broadcast-domain-wide
B. system-defined
C. local-only
D. sfo-partner-only
Answer: C
Explanation:
The local-only failover policy is he default setting for cluster LIFs and node management LIFs. Reference: Types of failover policieshttps://library.netapp.com/ecmdocs/ECMP1636021/html/GUID-92CC5F58-5EB8-4E2D-88F0-FA2F740062E0.html
Q18. You are asked to complete a 2-node installation of a FAS8060 cluster running clustered Data ONTAP 8.3. The hardware has been installed and the cluster has been configured. AutoSupport testing has not been successful because NetApp Support cannot see any messages, and the customer does not have any messages in their inbox.
Which two actions should be performed to test the functionality from the NetApp cluster? (Choose two.)
A. Verify that the network gateway responds to a ping request.
B. Verify that the mailhost responds to a ping request.
C. Verify that the domain controller responds to a ping request.
D. Verify that the cluster interconnect switches respond to a ping request.
Answer: B,D
Explanation:
B: Check that the mail host specified in the options is a host that the storage system can talk to, by running the following command on the storage system: ping mailhost_name mailhost_name is the name of the mail host specified in the AutoSupport options.
D: If the system cannot deliver AutoSupport messages over SMTP you should confirm basic network connectivity and DNS lookup: Your network management LIF must be up for operational and administrative status. You must be able to ping a functioning host on the same subnet from the cluster management LIF (not a LIF on any of the nodes). You must be able to ping a functioning host outside the subnet from the cluster management LIF. You must be able to ping a functioning host outside the subnet from the cluster management LIF using the name of the host (not the IP address).

Q19. You are adding nodes to an existing cluster.
In this scenario, which three statements are correct? (Choose three.)
A. If you are adding a second node to a single-node cluster, the second node must have been installed, but the cluster network can be configured later.
B. You must add a cluster switch for every two nodes.
C. If you are adding nodes to a multiple-node cluster, more than half of the existing nodes in the cluster must be healthy.
D. The switchless cluster functionality is supported only in a single or two-node cluster.
E. 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.
Answer: B,C,E
Explanation:
C: If you are adding nodes to a multiple-node cluster, more than half of the existing nodes in the cluster must be healthy (indicated by cluster show).
E: 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. Incorrect: not A: If you are adding a second node to a single-node cluster, the second node must be installed, and the cluster network must be configured. Not D: The switchless cluster functionality is supported only in a two-node cluster.

Q20. A customer is installing a new system and has determined that they have a broken disk.
What information is required to open a NetApp Support case?
A. disk HBA firmware and serial number
B. mainboard rev. id
C. serial number or system ID
D. disk shelf serial number and shelf ID number
Answer: C
Q21. You are installing a 4-node cluster with two CN1610 switches. Your co-worker is setting up the switches, but accidentally deletes the current configuration.
According to NetApp, what is the recommended way to restore the configuration?
A. Install only one switch.
B. Manually configure the ports as they are designated in the CN1601 and CN1610 Switch Setup and Configuration Guide.
C. Reload the same reference file to the switch.
D. Copy the configuration from a switch that is working.
Answer: D
Explanation:
You re-create the cluster using the cluster configuration that you chose and made available to the recovering node, and then rejoin each additional node to the new cluster. You should only perform this task to recover from a disaster that resulted in the loss of the cluster's configuration. Steps On the recovering node, use the system configuration recovery cluster recreate command at the advanced privilege level to re-create the cluster. Use the cluster identity show command to verify that the recovering node has a different UUID than the other nodes. For each node that needs to be joined to the re-created cluster, do the following: 3a. From a healthy node on the re-created cluster, use the system configuration recovery cluster rejoin command at the advanced privilege level to rejoin the target node to the cluster. Example This example rejoins the target node (node2) to the re-created cluster. cluster1::*> system configuration recovery cluster rejoin -node node2 Warning: This command will rejoin node "node2" into the local cluster, potentially overwriting critical cluster configuration files. This command should only be used to recover from a disaster. Do not perform any other recovery operations while this operation is in progress. This command will cause node "node2" to reboot. Do you want to continue? {y|n}: y The target node reboots and then joins the cluster. 3b. Use the cluster show command with the -eligibility parameter to verify that the target node is healthy and has formed quorum with the rest of the nodes in the cluster. The target node must rejoin the re-created cluster before you can rejoin another node.

Q22. Your customer received an HA pair of FAS8040 nodes with two half-populated disk shelves which they want to add to their cluster. When you arrive to add the nodes to their cluster, the customer informs you that they have 24 NSE drives that they want to use to fully populate two of the disk shelves.
What should you do in this scenario?
A. Change the boot variable bootarg.strorageencryption.support to false.
B. Move all the NSE disks into one shelf and all the hard disks into the other shelf before you install the new HA pair.
C. Inform your customer that they cannot mix NSE drives and regular hard disks in a storage system.
D. Comply with your customers request, and add the NSE drives before you add the nodes and disk shelves to their cluster.
Answer: C
Explanation:
All disks in the storage system and optional attached disk shelves must have encryption functionality to be able to use Storage Encryption. You cannot mix regular non-encrypting disks with self-encrypting disks. Note: NetApp Storage Encryption (NSE) is NetApp’s implementation of full-disk encryption (FDE) using self-encrypting drives from leading vendors.
