Job is started.

Job is failed.

Job is put into the queue.

Job is not started.

2. A new Isilon administrator has created their first quota of 100 TB on a directory called “/ifs/Boston-zone/ RnD”. Both the Engineering and QA teams have access to this directory. The directory sits on a 4-node H400 node pool.

Two weeks later, the administrator notices that the team’s available disk space is decreasing faster than anticipated for the “/ifs/Boston-zone/RnD” directory.

3. An Isilon administrator wants to create a new SMB share to an existing directory structure. The directory contains migrated production data and has an active NFS export.

What will happen if the administrator selects the “Apply Windows default ACLs” option during creation?

Windows default ACLs are overwritten by the existing mode bit rights.

Existing mode bit rights are overwritten by the Windows default ACLs.

Windows default ACLs are merged with the existing mode bit rights.

Creation of the SMB share fails due to the existing mode bit rights.

How many days will pass before you are prompted to commit the upgrade in the WebUI?

5. A systems administrator must ensure that an IP address never becomes unavailable, even if a node goes offline.

What needs to be configured on SmartConnect?

Dynamic Allocation

Static Allocation

Connection Count

Round Robin

6. What information is required to enable the LDAP service on an Isilon cluster?

Administrator account and password, and LDAP server name and IP address

Port number, cluster name, and an LDAP server IP address

Base distinguished name, cluster name, and port number

Base distinguished name, port number, and at least one LDAP server

7. DRAG DROP

What is the correct hierarchy of the Job elements structure?

8. What are the two ways a FlexProtect job can start?

An at or batch command and Non-event driven

Administrative and Even-driven

An at or batch command and Alert-driven

Administrative and Alert-driven

9. What is the maximum number of nodes that can be added into a node pool in Isilon Gen 6 hardware and OneFS 8.2.0?

144

252

288

352

10. When reconciling permissions for clients using UNIX as well as Microsoft Windows systems, what describes the scope of the permissions?

Windows ACLs and POSIX bits have overlapping semantics, but neither completely reflects the other.

Windows ACLs have semantics that are a subset of POSIX bits.

POSIX bits have semantics that are a subset of Windows ACLs, but Windows ACLs are more extensive.

POSIX bits and Windows ACLs are semantically equivalent.

11. You are configuring the network on a Isilon source cluster. The administrator wants to dedicate a new subnet for replication.

Which consideration must be addressed for SyncIQ to work properly?

SyncIQ must run on a static IP pool.

SnapshotIQ must be licensed first.

10GbE ports must be used for replication

SyncIQ must run on a dynamic IP pool

12. You have been tasked with designing SyncIQ policies for a systems administrator that requires failover and failback testing.

What information should be provided to the administrator?

SyncIQ supports failback replication policies that specify directory includes or excludes.

Failback replication policies that specify includes or excludes cannot use data encryption.

Failback replication policies that specify includes or excludes are not supported with SyncI

Failback replication policies that specify includes or excludes cannot use historical snapshots.

13. Based on the exhibit.

What is the actual protection level of the FEATURE.wmv file?

N+1

N+2

N+2n

N+2d: 1n

14. Which access information is represented in the exhibit?

Real ACL is applied and group “DEESdomain users” has read access to the file

Real ACL is applied and group “DEESsales” has read access to the file

Synthetic ACL is applied and group “DEESsales” has read access to the file

Synthetic ACL is applied and user “DEESjohn” has read access to the file

15. When reviewing the actual protection output of N+4/2, what does the number “4” represent?

FEC stripe units per stripe

Hard drives used per stripe

Volume stripes per file system

FEC stripe units per file system

16. What impact can obsolete drive firmware have on an Isilon cluster?

Reduces administrative overhead and increases performance.

Affects redundancy settings and FEC coding.

Affects cluster performance or hardware reliability.

Increases runtime and cluster performance.

17. What defines FEC link aggregation mode?

Switches to the next interface when the primary interface becomes unavailable.

Balances outgoing traffic based on hashed protocol header information that includes source and destination addresses, and VLAN tag.

Balances outgoing traffic based on hashed protocol header information that includes source and destination addresses.

Balances outbound traffic across all active ports in the aggregated link.

18. In Isilon OneFS, what is a characteristic of CoW with snapshots?

Used for more substantial changes such as deletes.

19. Which OneFS networking option enables Isilon for DNS multitenant functionality?

Groupnet

Access zone

Pool

Subnet

20. A company wants to re-use HD400 nodes into a new cluster with OneFS 8.2.0.

21. On which node does the SSIP initially reside?

Highest node ID

Lowest node ID

Lowest logical node number

Highest logical node number

22. An Isilon cluster has four H500 nodes. Data protection and access are set to N+1 and concurrency respectively.

How many drives will be used across the disk pool to protect a 1 MB file?

23. DRAG DROP

Refer to the Exhibit.

In an Isilon environment, match the connectivity type to the proper numerical port reference shown in the exhibit.

24. A company’s Isilon cluster has reached the capacity limit. The cluster consists of eight H500 nodes in a single node pool.

Which action can be taken to resolve the capacity issue while new nodes are being delivered?

Activate SmartPools

Enable GNA

Enable Spillover

Release VHS drives

25. Which command shows the node running as the job coordinator?

isi job statistics

isi job status

isi job status -v

28. A company has a 4-node Isilon H600 cluster dedicated for a high-performance workflow. The administrator wants to convert their cluster SSD strategy from L3 cache to use the SSDs for metadata acceleration.

What should be considered?

Migration of data and metadata from the SSDs to HDDs can take hours.

Once enabled, the L3 cache cannot be disabled without support assistance.

Converting to use SSDs for metadata acceleration turns off prefetching.

Deselecting L3 cache for an SSD strategy has no impact to the workflow.
