Q1. - (Topic 3)

How many concurrent SSH administrative sessions for a node are supported?

A. 25

B. 64

C. 128

D. 125

Answer: B

Q2. - (Topic 1)

Which data protocol is available to use on an SVM?

A. FTP

B. CIFS

C. HTTP

D. TFTP

Answer: B

Explanation: You can configure CIFS and NFS protocols on the.Storage Virtual Machine (SVM).to provide file-level data access for NAS clients. To enable CIFS protocol, you must create the data LIFs and the CIFS server. To enable NFS protocol, you can specify the NIS details in addition to the data LIFs.

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."
