Isilon Infrastructure Specialist Exam for Technology Architects Sample Questions:
1. 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 solutions can enable failover to other nodes with the use of client-side drivers.
B) Isilon OneFS enables each node to be a peer to any other node in an Isilon cluster.
C) Isilon OneFS enables each node to have a designated partner node for simple failover between the pair.
D) Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.
2. An Isilon customer's administrator created the nested directory structure, shown in the exhibit,
using SmartQuotas. However, a user needs to write an additional 650 GB of data to "/ifs/data/acct/recv".
Which steps will enable the user to complete this task?
A) Increase the Directory1 Quota to 1400 GB Increase the User Quota on Subdirectory2 to 1000 GB
B) Increase the Directory1 Quota to 1350 GB Decrease the user Quota on Subdirectory1 to 1000 GB
C) Decrease the User Quota on Subdirectory2 to 650 GB Decrease the Directory1 Quota to 1650 GB
D) Decrease the User Quota on Subdirectory1 to 400 GB Increase the Directory1 Quota to 1650 GB
3. By default, how much space needs to be reserved for snapshots on an Isilon cluster?
A) 20% of the cluster
B) 10% of the cluster
C) 5% of the cluster
D) 0% of the cluster
4. If a file is 4 KB in size, how much space is consumed for file data when it is written to the Isilon cluster?
A) 32 KB
B) 8 KB
C) 16 KB
D) 4 KB
5. An Isilon customer has two 5-node clusters, one for production and one for disaster recovery (DR). The customer's workflows are replicated to the DR cluster through SyncIQ on individual schedules. They have shutdown their production cluster for scheduled maintenance, failed over to the DR cluster, and are currently operating from the DR site.
Assume both clusters have identical shares, exports, user authentication, and that the client applications have been stopped and the DNS re-pointed. What is the easiest method to continue operations on production?
A) Initiate Manual Failback of the SyncIQ Policy
B) Revert the SyncIQ Policy
C) Initiate Automated Failback of the SyncIQ Policy
D) No change to the SyncIQ Policy
