QuestionQ1

NAS, PowerScale, and OneFS

Which OneFS networking option allows Isilon to provide DNS multitenant functionality?

  • A Groupnet
  • B Access zone
  • C Pool
  • D Subnet
Explanation

A groupnet is the OneFS networking container used to manage multiple external-network tenants. It owns DNS client settings such as nameservers and DNS search lists, so separate groupnets can provide distinct DNS namespaces and name-resolution behavior.

QuestionQ2

NAS, PowerScale, and OneFS

What number of delegations is recommended for a SmartConnect zone name and for each SmartConnect zone alias on a cluster?

  • A 1
  • B 2
  • C 3
  • D 4
Explanation

Dell PowerScale recommends a single DNS delegation for each SmartConnect zone name and each SmartConnect zone alias configured on the cluster. This lets DNS direct requests for that specific name to the SmartConnect service.

QuestionQ3

NAS, PowerScale, and OneFS

When configuring NTP on a 4-node Gen 6 cluster, how many chimer nodes are automatically configured for the cluster?

  • A 1
  • B 2
  • C 3
  • D 4
Explanation

OneFS selects three chimer nodes by default for clusters with more than three nodes. Chimer nodes contact external NTP servers, while non-chimer nodes use the chimers as their NTP servers.

QuestionQ5

Configuring Identity Management and Authorization

When reconciling permissions for clients that use UNIX as well as Microsoft Windows systems, what characterizes the scope of those permissions?

  • A Windows ACLs and POSIX bits have overlapping semantics, but neither completely reflects the other.
  • B Windows ACLs have semantics that are a subset of POSIX bits.
  • C POSIX bits have semantics that are a subset of Windows ACLs, but Windows ACLs are more extensive.
  • D POSIX bits and Windows ACLs are semantically equivalent.
Explanation

POSIX mode bits provide a limited owner/group/other read-write-execute model, whereas Windows ACLs provide more granular access-control entries. Because the two models have overlapping but non-identical permission semantics, neither model completely represents the other.
