Study with E20-554 Actual Test Questions

Your customer has observed a degradation in response time while browsing for media files within the Production Media folder on 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?

• A. Add an A-Series Performance Accelerator node
• B. Add Solid State Drives (SSDs) to the nodes
• C. Upgrade RAM on the nodes
• D. Upgrade network interfaces on the nodes to 10 Gbps

Refer to the exhibit.

A large hospital chain has approached you to redesign their storage infrastructure. The head of IT believes their requirement is for 100 TB of RAW capacity. They want to consolidate their PACS, file shares and home directories onto one cluster and require very fast enumeration of the directories. The following are the notes from meetings with the department heads.Which is the best cluster configuration that meets the customer's requirements?

• A. 5 x S-Series nodes
• B. 4 x X-Series nodes using SynqIQ to 4 x NL-Series nodes
• C. 3 x S-Series nodes using SmartPools and 3 x NL-Series nodes for Archive
• D. 3 x NL-Series nodes using SynqIQ to 3 x NL-Series nodes

When designing Isilon solutions, what issues should you pay special attention to?

• A. Solutions Document Balance technical and business requirements Downstream hand-off Design to meet customer expectations
• B. Avoid being too enthusiastic over the technology Balance technical and business requirements Provide options Design to meet customer expectations
• C. Solutions Document Balance technical and business requirements Provide options Practical vs. theoretical implementations
• D. Workflow Document Solutions Document Application types Data strategy

A potential customer requires 800 TB of usable capacity to store medical images for their network of health clinics. The IT department has limited staff and currently manages four storage arrays from other vendors. During a meeting with the Director of IT you learn that the company is considering a solution from a competitor of EMC using two of the existing arrays and two new arrays.Which Isilon capabilities would show a better ROI for the customer?

• A. Forward Error Correction overhead is 7% lower than traditional RAID.
  Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.
  According to an IDC study, Isilon improves IT productivity by nearly 50% compared to traditional competitors.
• B. Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions.
  With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically
  80% or higher.
  Isilon utilization is typically 80% or higher due to use of a single filesystem and virtual capacity for
  drive and node failures.
• C. Isilon has 15%-20% less overhead than traditional clustered filesystems.
  According to an IDC study, Isilon utilization is nearly 50% higher than traditional competitors.
  Isilon QOS headroom and multiple node pools ensures consistent performance up to 80%
  utilization.
• D. With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically
  80% or higher.
  OneFS compression results in higher effective capacity within the cluster.
  Traditional clustered filesystems require 4%-10% internal overhead compared to Isilon virtual
  capacity.

While validating the value (VTV) with a large educational customer, they have decided they would like to add a Disaster Recovery (DR) site to their existing Isilon environment. The existing cluster contains six X-Series nodes. They plan to have all workflows replicated to the DR site and both clusters will have identical shares, exports, and user authentication. The customer would like to test DR failover every six months by running their production environment from the DR site.
What would you recommend for the DR solution?

• A. SyncIQ and identical cluster at the DR site
• B. Equal number of S-Series nodes at the primary site
• C. SyncIQ and NL-Series nodes at the DR site
• D. SmartConnect and NL-Series nodes at the primary site
