Exam 5: XtremIO Solutions and Design Specialist Exam for Technology Architects

During a write process in OneFS 8.0, from which cache are blocks copied to disk?

For concurrent I/O, how do SmartCache and Endurant Cache differ?

Refer to the exhibit. Which tool was used to create this output and what is the most telling characteristic?

At a minimum, how many connected and available nodes are required to maintain quorum in a 25-node cluster?

What is the minimum number of nodes in an Isilon cluster for N+2 protection?

When an Isilon SyncIQ replication job completes, how many SnapshotIQ policies can be created on a target cluster directory?

An Isilon customer wants a job to periodically check disk sectors to ensure they can be read. What should be recommended to the customer?

What key considerations should be kept in mind when designing a 300TB solution?

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.)

Which type(s) of data is predominately associated with home directories and file shares?

There is a requirement to use dynamic link aggregation to maximize throughput and resiliency on a new Isilon cluster servicing SMB and NFS data. What is the recommended configuration for the physical network interfaces?

Which OneFS roles should be assigned to an Active Directory group for login privileges equivalent to the 'admin' local account?

A customer is having problems writing data to their Isilon cluster. You have checked all network settings and authentication sources. No errors are reported from the cluster. The customer runs tcpdump and sends the results to you. Now that you have the output, which tool would you use to open the results file?

A customer plans to replace an existing array that is supported by the MiTrend Workload Profile Assessment (WPA) service. You receive performance data from the customer and run a WPA report that shows the array has 50TB of usable capacity. In discussions with the customer, you learn the content is comprised of four million 6MB files and 400 million 64KB files. The customer explains they have a small budget and very limited rack space available in their datacenter. Performance is not a concern because the files are rarely accessed. Which configuration provides the needed usable capacity using N+2:1 protection, and requires the least amount of rack space?

You are designing a new Isilon system to store mobile device video clips. The files average 800MB in size and the application team tells you to plan for up to 15,000 new files per day. The product manager for this new service wants enough capacity for the first year and reminds you that response time for storing and retrieving the files is important for customer satisfaction. The files will be accessed frequently for the first 48 hours after creation, and then very infrequently after seven days. You plan to use N+2:1 protection, and will configure a SmartPools policy to move inactive files to an archive tier within the cluster. Which configuration best fits the project requirements?

Which OneFS feature enables you to host multiple tenants from mutually untrusting AD authentication environments from the same DNS namespace?

A customer plans to deploy N+2:1 protection on a 5-node Isilon cluster. How much capacity will be used to store a 320 KiB file?

A company currently has numerous file servers providing home directories for its employees. Some departments have their own file servers. All corporate users authenticate using Active Directory. The engineering department has their own untrusted AD domain for their file servers. The company is looking for a consolidated solution that requires minimal changes to the environment, and that creates a single namespace for the home directories. What is the recommended solution that will meet this company's requirements?

A customer is considering a six brick dispersed cluster using 3×40U racks. The customer wants advice on racking the InfiniBand switches. Rack 1 (left) contains X-Bricks 1 and 2 Rack 2 (middle) contains X-Bricks 3 and 4 Rack 3 (right) contains X-Bricks 5 and 6 Which recommendation should be provided?

Your customer is looking for a storage solution that will be able to store seven million 3 MB files, which are written and seldom accessed. Read and write operations are both completed by a web-based application, which requires 1.3 Gbps throughput. The customer's network has not been upgraded in many years, so the network interfaces are 1Gbps. Which cluster configuration would best meet the customer's requirements?
