How many layers are in the Isilon clustering architecture?

A. 2

B. 4

C. 6

D. 8

An Isilon customer expressed an interest in more effectively managing their storage. Specifically, they would like to plan for future growth.

Which tool would allow the customer to forecast capacity requirements?

A. InsightIQ

B. Isilon SNMP MIB

C. SyncIQ

D. SmartPools

Your customer has an existing Isilon cluster comprised of five NL-Series nodes. They have a new project that will quadruple their current throughput requirements. Upon reviewing reports in InsightIQ, you see that the aggregate external network throughput is peaking at 600MB/s. The customer states that data is only active for the first 7 days, but they keep it indefinitely.

Which recommendation best supports their growth requirements?

A. Add X-Series nodes to the cluster, and use SmartPools to migrate inactive data to the NL-Series nodes.

B. Use the Isilon Sizing Tool to determine GNA requirements, and add NL-Series nodes with SSD to the cluster.

C. Add a VNX Unified array for the new project, and use rsync to migrate data to the Isilon cluster for archiving.

D. Add A-Series nodes to the cluster to boost combined network performance.

Traditional NAS storage architecture deploys simple two-way failover between two controllers in their storage systems, such as highly-available configurations. How is the Isilon architecture different in terms of system resiliency and availability?

A. Isilon OneFS enables each node to have a designated partner node for simple failover between the pair.

B. Isilon solutions can enable failover to other nodes with the use of client-side drivers.

C. Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.

D. Isilon OneFS enables each node to be a peer to any other node in an Isilon cluster.

A cluster has user quotas configured for user's home directories with hard limits and advisory limits set. What would the default setting be for calculating user quotas on the cluster?

A. User data and data protection overhead only

B. User data only

C. User data, snapshot data, and data protection overhead

D. User data and snapshot data only

A company has purchased an Isilon cluster. The storage administrator knows they will have a large number of clients with similar workloads connecting to the cluster through NFS, and connections will be maintained for a long time. Which two connection balancing policies should be recommended for initial use? (Choose two.)

A. Round Robin and Connection Count

B. CPU Utilization and Network Throughput

C. Round Robin and CPU Utilization

D. Connection Count and Network Throughput

When a Gen 6 Isilon cluster receives a file to be stored, which node(s) performs the FEC calculation?

A. First node in each node pair

B. Node that will be holding the FEC

C. Node to which data was initially sent

D. Each node in the cluster

If snapshots are configured for the InsightIQ datastore on Isilon and the datastore is reverted to a previous snapshot, what might be the result?

A. InsightIQ datastore cannot be reverted

B. InsightIQ database will have to be manually copied from the snapshot

C. InsightIQ datastore could be corrupted

D. InsightIQ will not recognize the older copy of the database

What is the recommended namespace path for the access zone on a new Isilon cluster with SyncIQ license?

A. /ifs//data

B. /ifs///data

C. /ifs//data

D. /ifs///data

A customer has a cluster running with a single access zone and serves multiple internal departments. The clients access the cluster over both SMB and NFS protocols. A department user has been assigned the task of auditing SMB activity and enforcing appropriate quotas for certain users.

How should the cluster administrator grant this access?

A. Create a custom RBAC role

B. Create a secondary root account credential

C. Provide the AuditAdmin RBAC role

D. Provide the SecurityAdmin RBAC role
