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

Where is caching for disk blocks staged on an Isilon node?

You have scheduled a meeting with a prospective customer in the Life Sciences vertical market. Which Isilon features should be presented to them?

A potential customer is considering replacing a four year old, Linux-based NFS server with 40TB of usable capacity. The existing system supports home directories, an internal website, and a content repository for the customer's content management system. The customer is concerned about performance of any new solution because they expect to double workload in the content management system. What tools can be used to collect performance data needed to size the new solution?

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

A customer plans to migrate data to a remote Isilon cluster. What is a consideration when configuring a cluster with SyncIQ and hard SmartQuotas?

A customer has a 7-node Isilon cluster configured with N+2:1 protection. How many nodes can be offline with the data accessible and fully writeable?

Which SCSI instructions are used to build a bitmap of the changes between the first snapshot and subsequent snapshots when RecoverPoint is used with XtremIO?

In an Isilon cluster for N+2 protection, what is the minimum number of nodes?

Which SmartConnect policies are used for workloads that have short lived connections such as HTTP and FTP?

What is considered typical performance for an XtremIO single X-Brick cluster?

You have gathered information from your customer about their current NAS environment. They indicated they are having performance and time-out issues with their clients accessing the storage. Currently over 5000 clients are simultaneously accessing the NAS; however, this will double in the next year. Based on this information, what recommendations for a new Isilon cluster would you give to the customer based on this information?

Which Isilon feature provides the ability to build a cluster using different node types and tiers to meet a customer's business objectives?

Which Isilon job periodically checks disk sectors to ensure they can be read?

A customer has grown 2 PB in the last year. The cluster performs well most times of the day, but occasionally during the day, the customer notices a decrease in performance. You have been told that 'tree-deletes' are taking too long and can only be run on weekends. What would you recommend to speed up the 'tree-deletes'?

A storage administrator wants to add a volume to their XtremIO storage array using the RESTful API. Which RESTful method should be used to complete this task?

Using Isilon SnapshotIQ, how many snapshots can be created at the directory level?

You are reviewing an opportunity with a trusted advisor. You both discover gaps in the initial solution design. Each iterative discussion with the customer helps you define the solution better. The documents produced capture the customer's requirements. What else needs to occur to refine the sizing considerations?

An Isilon customer has two 5-node clusters, one for production and one for disaster recovery (DR). The customer's workflow is a SmartLock workflow and is replicated to the DR cluster through SyncIQ on an individual schedule. The customer needs to shutdown their production cluster for scheduled maintenance. 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 correct method to start operations on the DR cluster?

You are sizing an Isilon Cluster for a new customer. Analyzing their workflow, you determine that they have a small block random read workload. What is the most important factor to consider when sizing this solution?

An Isilon customer needs to grant a specific administrator on RBAC privilege. What does the customer need to do?
