Q5. - (Topic 3) 

Which protocol(s) does Infinite Volumes support? 

A. All supported protocols on Data ONTAP 

B. NFSv3 and NFSv4 only 

C. NFSv2 and NFSv3 only 

D. File access and protocol improvements 

E. NFSv3 and SMB 1.0 only 

Answer:

Explanation: Infinite Volumes use the unified security style, which enables all clients to view and set file permissions, regardless of the file permissions that are currently in effect on a given file or directory. Unified security style also facilitates access checks using both Windows and UNIX credentials.

Q9. - (Topic 3) 

Which are types of failover groups? (choose all that apply) 

A. System-defined 

B. User-defined 

C. Next Available 

D. Priority 

E. Clusterwide 

Answer: A,B,E 

Explanation: Types of failover groups 

Failover groups for LIFs can be system-defined or user-defined. 

Additionally, a failover group called clusterwide exists and is maintained automatically. 

Failover groups are of the following types: 

System-defined failover groups: Failover groups that automatically manage LIF failover 

targets on a per-LIF basis. 

This is the default failover group for data LIFs in the cluster. 

For example, when the value of the failover-group option is system-defined, the system will 

automatically manage the LIF failover targets for that LIF, based on the home node or port 

of the LIF. 

Note: All the network ports should be assigned correct port roles, and all the network ports 

of the same role should be in the same subnet. 

User-defined failover groups: Customized failover groups that can be created when the 

system-defined failover groups do not meet your requirements. 

For a system with ports of the same role connected to multiple subnets, each LIF requires 

a user-defined failover group with a failover group for each subnet. 

You can create a failover group consisting of all 10-GbE ports that enables LIFs to fail over 

only to the high-bandwidth ports. 

Clusterwide failover group: Failover group that consists of all the data ports in the cluster. 

This is the default failover group for the cluster-management LIFs only. 

For example, when the value of the failover-group option is cluster-wide, every data port in 

the cluster will be defined as the failover targets for that LIF."

Q10. - (Topic 2) 

Which statement is true about clustered Data ONTAP 8.2 node based licensing? 

A. When replacing a controller for a RMA the key is automatically updated to the serial number of new controller. 

B. When replacing a controller for a RMA, a new key is needed but the existing key will work for 90 days. 

C. A new clustered Data ONTAP 8.2 installation can use both 8.1 keys and 7-Mode keys. 

D. Replacing a NVRAM card in a controller will NOT require new license keys for that mode. 

Answer:

Explanation: Explanation/Reference: If you replace or upgrade a controller that is running Data ONTAP 8.2, within a grace period (up to 90 days) the new controller can use the same licensed functionality that the original controller had
