• Question 92:

  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

  Correct Answer: D

  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.

• Question 97:

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

  A. System-defined

  B. User-defined

  C. Next Available

  D. Priority

  E. Clusterwide

  Correct Answer: ABE

  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."
