   A PowerScale cluster has a file with an ACL that grants access to a Windows group. The group's SID is S-1-5-21-...-512. An NFS client tries to access the file, but access is denied. The administrator checks the ID mapping and sees that the group's SID is not mapped to a GID. What is the most likely reason for the access denial?

   • AThe NFS client is not configured to use the PowerScale cluster's user database.
   • BThe group's SID cannot be translated to a GID, so the NFS client cannot match the ACL entry to the user's group membership.
   • CThe NFS client does not support ACLs, so it ignores the ACL and uses the file's basic permissions.
   • DThe file's basic permissions are set to 600, which denies access to all users except the owner.

   What is the impact of ID mapping on SMB clients in PowerScale?

   • AIt converts SMB shares to NFS exports
   • BIt allows SMB clients to use Unix permissions directly
   • CIt translates the SID from the SMB client to a UID/GID so the cluster can apply POSIX permissions when needed
   • DIt blocks SMB clients from accessing files with Unix permissions

   A PowerScale cluster has two access zones: 'ZoneA' for the engineering department and 'ZoneB' for the finance department. Both zones use the same Active Directory domain. The administrator needs to configure ID mapping so that users in ZoneA get UIDs from a specific range, while users in ZoneB get UIDs from a different range. What is the correct approach?

   • AUse the same mapping rule but modify the NFS export options for each zone to change the UID.
   • BCreate two separate Active Directory domains, one for each zone, and configure mapping for each.
   • CConfigure separate ID mapping rules for each zone, with each rule specifying the desired UID range.
   • DConfigure a single ID mapping rule and apply it to both zones, since they share the same AD domain.

   What is the primary purpose of ID mapping in PowerScale?

   • ATo translate between Windows SIDs and Unix UIDs/GIDs so that users from both environments can access the same files
   • BTo encrypt user passwords stored on the cluster
   • CTo assign unique IP addresses to users for network access
   • DTo synchronize user account attributes between Active Directory and LDAP
