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

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

Independent of protocol, what does Isilon OneFS use to translate identities?

Refer to the exhibit. You are analyzing a customer's existing Isilon environment using InsightIQ in order to expand the cluster. When examining the protocol data, you see the output as shown. What does the data tell you about the workload?

Your customer purchased an Isilon cluster with eight X400 nodes for Home Directories. Your follow-up discussions have uncovered an opportunity to expand the cluster to support the Legal Department. As you prepare to complete the Workflow Profile Document, you meet with the customer to discuss data protection. Which key areas should you address?

How is the journal protected in Gen 6 hardware?

Which Isilon OneFS job, that runs manually, is responsible for examining the entire file system for inconsistencies?

A customer has a data retention period of three years. They want a solution in which files cannot be deleted, changed, or modified. Which Isilon SmartLock version should they implement?

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?

A storage administrator is configuring SAN switches and zoning to connect an eight X-Brick XtremIO array. A VMware ESXi server is hosted on a blade chassis with 16 HBA ports. In addition, the SAN is composed of two separate SAN switches. What is the recommended XtremIO best practice for zoning?

An Isilon customer wants to have different snapshot policies and schedules on the same directory. Why is this possible on an Isilon cluster?

A customer has a workload with the following attributes: Generates 250,000 IOPs 100 TB in logical capacity Read/Write ratio of 1:1 Random workload with 8 kB I/O size Deduplication ratio of 2:1 Compression ratio of 2:1 Which XtremIO solution should be recommended to the customer?

A customer is considering migrating their existing non-EMC storage arrays to an XtremIO array. The current environment consists of 350 servers running VMware ESXi 5.5 with 5000 virtual machines. The customer has various tools in place to monitor performance and collect statistics. On average, their service time is 32 ms and utilization is at 75%. In the past, the customer has had performance issues. Based on Little's Law, what is the calculated response time on the existing environment?

A Linux administrator is attaching a new RHEL server to their XtremIO storage array. Which configuration setting should be changed?

Which feature of OneFS is used in the Home Directory and File Share vertical to monitor storage and media clients for optimal performance?

At which level can retention periods be applied with Isilon SmartLock?

A customer is considering moving their NAS data over to Isilon systems. They want to know if the Isilon systems have any limitations regarding snapshots. What explanation can be provided?

How many file systems are present in a 20-node Isilon X200 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?

You meet a customer for the first time. They explain that their current environment for NAS does not meet their needs. You want to make sure that Isilon is a good fit for their needs. What would be a good prequalifying question to ask?

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?
