Question 3

A customer is planning an Isilon deployment for use with their Hadoop environment. What is one advantage of using Isilon as the HDFS layer?

Accepted Answer

Isilon allows for independent scaling of compute and storage nodes, which is beneficial in a Hadoop environment as it enables flexibility and efficiency in resource allocation.

Question 4

Accepted Answer

The VHS (Virtual Hot Spare) is specified as 15 percent of the node pool, which means 15% of the total space in the node pool is reserved for VHS.

Question 5

Which SyncIQ policy is required if the goal is to have all source data replicated and to retain deleted files?

Accepted Answer

Sync Policy is required to have all source data replicated and to retain deleted files.

Question 6

Your customer has observed a degradation in response time while browsing for media files within the Production Media folder of the Isilon cluster. That directory now contains over five million files. It was confirmed that there are no network or edit station related causes. What changes to the Isilon cluster will best accelerate the browsing performance?

Accepted Answer

Adding SSDs to the nodes will accelerate the browsing performance by providing faster access to the files.

Question 7

An architect is designing a new cluster. The cluster contains H500 nodes to store home directories of 2000 users and A200 nodes to store backups of VMware virtual machines. Which data access patterns should be used?

Accepted Answer

The H500 nodes storing home directories should use streaming access patterns for efficient sequential data access, while the A200 nodes storing backups should use random access patterns for efficient handling of non-sequential data.

Question 8

A 6 × F800 node Isilon cluster has one subnet with two IP pools with LACP aggregated 10GigE interfaces from all the nodes in the 'Data-Zone' Access Zone. The 'NFS-Pool' with dynamic IP Allocation schema and 'SMB-Pool' with static IP Allocation schema are being used. All the Linux clients are accessing Isilon exports using NFSv3 via the 'NFS_Pool'. All the Windows clients are accessing Isilon shares using SMBv3 via the 'SMB_Pool'. While deploying Isilon, the customer reserves the whole network subnet for Isilon. The customer is facing performance issues with a new workload that is accessing the Isilon via Kerberized NFSv4. What is recommended when creating a new IP pool for NFSv4 clients?

Accepted Answer

The answer of A 6 × F800 node Isilon cluster...

Question 9

You meet with the IT Director of a large single site campus. The IT department has recently taken over Physical Security from the facilities department and plans a complete overhaul of the surveillance solution. They are looking to you as a storage architecture expert to provide the correct amount of storage needed. The IT Director asks you what items they need to provide in order to size this solution. What data do you require from the customer?

Accepted Answer

You need the resolution, codec, frames per second, number of devices, and retention time to calculate the storage requirements for a surveillance solution.

Question 10

A customer needs to be able to periodically monitor their node live performance for ongoing operational tasks as well as during problem analysis. You have recommended they use the isi statistics command to fulfill this need. What types of statistics and statuses could be displayed with this command?

Accepted Answer

The isi statistics command can display protocol status, drive statistics, hardware statistics, and node statistics, which are essential for monitoring node performance.

Question 11

A customer wishes to back up their Isilon cluster via NDMP using a software package that supports NDMP connectivity. The backup process will require the cluster to create a point-in-time copy of the directory to be backed up. Which OneFS feature(s) will need to be licensed?

Accepted Answer

The answer of A customer wishes to back up their...

Question 12

Three jobs of different exclusion sets with a priority level of 5 are concurrently running on a cluster. A new job with a priority of 4 needs to be run. What does the Job Engine do?

Accepted Answer

The answer of Three jobs of different exclusion sets with...

Question 13

While configuring Isilon SmartConnect, a customer determined that their workload primarily consists of long-lived NFS and SMB connections. Which load-balancing policy will provide the most efficient client distribution?

Accepted Answer

The answer of While configuring Isilon SmartConnect, a customer determined...

Question 14

What is the minimum size and the maximum size, respectively, of a single pre-Gen 6 node pool?

Accepted Answer

Pre-Gen 6 node pools have a minimum size of 3 nodes and a maximum size of 144 nodes.

Question 15

A hospital is considering using Isilon to store their archived medical images and Genomic Sequencing data. They currently have 56 TB of PACS images and 24 TB of genomic data, and expect to double their capacity requirements this year. They will replicate to a DR cluster, and plan to use N+2 protection. The production workload needs to be run at either site. Which minimum cluster configuration, at each site, including software, would meet this customer's environment?

Accepted Answer

The hospital needs a solution that can handle 160 TB of data (80 TB at each site, considering the doubling of current data and replication). Five X400 nodes with 2 TB drives can provide sufficient storage capacity and performance, and SyncIQ is needed for replication.

Question 16

Which type of data is stored in Endurant Cache of an Isilon node?

Accepted Answer

Endurant Cache in an Isilon node is specifically used to store write data temporarily to ensure data integrity and performance before it is written to disk.

Question 17

Three jobs are running, all with a priority of 5. A new job with a priority of 6 needs to be run. What happens?

Accepted Answer

The answer of Three jobs are running, all with a...

Question 18

What is a benefit of using SSDs for Metadata Read/Write Acceleration?

Accepted Answer

SSDs improve the speed of metadata operations like create, write, and delete, leading to better overall performance.

Question 19

A four node F800 Isilon cluster running OneFS 8.2.1 has a dedicated subnet and IP pool for SMB data traffic. SmartConnect Advanced license is applied. The SMB IP pool consists of LACP aggregated. 10GigE interfaces from all the nodes. What is the maximum number of SmartConnect Service IPs recommended for the SMB subnet?

Accepted Answer

The maximum number of SmartConnect Service IPs recommended for a subnet is typically one. This is because the SmartConnect Service IP is used to provide a single point of entry for client connections, and having more than one can lead to unnecessary complexity and potential issues with load balancing and failover.
