Q1. - (Topic 1) 

What are the two valid NDMP modes? (Choose two.) 

A. local-scoped 

B. node-scoped 

C. SVM-scoped 

D. cluster-scoped 

Answer: B,C 

Reference: http://documents.software.dell.com/netvault-backup-plug-in-for-ndmp/10.0.5/application-notes-for-netapp-ontap/installation-and-configuration-prerequisites/configuration-prerequisites?ParentProduct=753 

If you install a new Data ONTAP 8.2 cluster, NDMP is in the SVM-scoped NDMP mode by default. To perform tape backup and restore operations in the node-scoped NDMP mode, you must explicitly enable the node-scoped NDMP mode

A. vserver 

B. node 

C. volume 

D. qtree 

E. aggregate 

F. LUN

Q6. - (Topic 1) 

A customer wants to retire a broadcast domain called bcast1 from the cluster. All network ports and data LIFs previously using bcast1 have been moved to another broadcast domain. When the administrator attempts to delete the broadcast domain, the deletion fails. 

What is causing the problem? 

A. TheIPspace, that the broadcast domain uses, still exists. 

B. The cluster ports are using the bcast1 broadcast domain. 

C. There are still subnets associated with the broadcast domain. 

D. The SVM has not been deleted. 

Answer:

Q7. - (Topic 2) 

What three statements are true about LIF failover? (Choose three.) 

A. A node management Ethernet LIF will never automatically revert back to its home port. 

B. A node management Ethernet LIF can fail over to its partner node when a port is down. 

C. A data Ethernet LIF will not automatically revert back to its home port. 

D. A cluster management Ethernet LIF will never automatically revert back to its home port 

E. A cluster management Ethernet LIF can fail over when a port is down. 

F. A data Ethernet LIF can fail over when the cluster is in quorum. 

Answer: B,C,E 

Explanation: https://library.netapp.com/ecmdocs/ECMP1401193/html/GUID-6DBD40F8-EA21-42AE-82CF-AEB556BEC783.html 

"Scenarios that cause a LIF failover 

LIF failover occurs in scenarios such as port failure, network interface failure, or cable failure. LIFs can be associated with failover rules that enable you to reroute the network traffic to other available ports in the cluster. 

LIF failover occurs in the following scenarios: 

When there is a power failure When automatic revert is enabled on a LIF and that LIF's home port reverts to the 

administrative up status The LIF automatically migrates back to the home port. When the port hosting a LIF is in the administrative down status The LIFs move to another port. When a node reboots or falls out of quorum The LIFs on that node fail over to the ports on other nodes. If a node returns to quorum, the 

LIFs automatically revert to the ports on the node, provided the ports are the home ports for 

the LIF and automatic revert is enabled on the LIF. 

For more information about quorum, see the Clustered Data ONTAP System 

Administration Guide for Cluster Administrators. 

When automatic revert is enabled on a LIF and that LIF's home port reverts to the administrative up status the LIF automatically migrates back to the home port."
