Question #6
You have just configured the customer's first SVM with a LIF IP 10.0.0.10/24. The customer's DNS IP address is 172.16.0.250 and you are unable to ping it from the NetApp storage system, but you are able to ping the gateway and everything else works.
In this scenario what is the problem?
In this scenario what is the problem?
- AYou need to have the DNS server on the same subnet as the LIF IP address.
- BYou need to add a static gateway to the LIFs routing group.
- CYou need to have the customer check the cable.
- DYou need to add an IPspace and domain broadcast to the port.
Correct Answer:
D
?️
A broadcast domain resides in an IPspace, and it contains a group of network ports, potentially from many nodes in the cluster, that belong to the same layer 2 network. The ports in the group are used in an SVM for data traffic.

Question #7
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?
According to NetApp, what is the recommended way to restore the configuration?
- AInstall only one switch.
- BManually configure the ports as they are designated in the CN1601 and CN1610 Switch Setup and Configuration Guide.
- CReload the same reference file to the switch.
- DCopy the configuration from a switch that is working.
Correct Answer:
D

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 -
1. On the recovering node, use the system configuration recovery cluster recreate command at the advanced privilege level to re-create the cluster.
2. Use the cluster identity show command to verify that the recovering node has a different UUID than the other nodes.
3. 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.

Question #9
According to NetApp, which two scenarios are recommended for a RAID-DP aggregate in clustered Data ONTAP 8.3? (Choose two.)
- Athree or more disks if it is a data aggregate
- Bthree or more disks if it is a root aggregate
- Ctwo or more disks if it is a root aggregate
- Dfive or more disks if it is a data aggregate
Correct Answer:
BD
?️
The minimum number of disks in a RAID-DP group is three: at least one data disk, one regular parity disk, and one double-parity (dParity) disk. However, for non- root aggregates with only one RAID group, you must have at least 5 disks (three data disks and two parity disks).

Question #10
Regarding clustered Data ONTAP 8.3, what happens to the roles of the on board ports, HBAs, and NICs?
- AThese roles are assignet when LIFs are created.
- BThese roles are assigned based on the controller type.
- CThese roles are predefined and must be changed before creating your LIFs.
- DThe roles are divided into two categories: Data Management and Node Management.
Correct Answer:
A
?️
In earlier releases of Data ONTAP, default roles were assigned to each Ethernet network port. The roles included data, cluster, cluster management, intercluster, and node management. In Data ONTAP 8.3, these roles are assigned when LIFs are created.
