Free EMC E20-554 Exam Dumps Questions & Answers

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?

• A.Default cluster protection level Backup windows and processes Concurrency of user access
• B.Default cluster protection level Additional directory level protections Snapshots and replication
• C.WORM requirements Network ports for replication Snapshots for user restores
• D.Protocols (SMB, NFS, FTP, HTTP, HDFS) Authentication and Directory Services Performance and latency concerns

Refer to the exhibit.

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

• A.It contains mostly random writes.
• B.It is mostly sequential reads.
• C.It is metadata intensive.
• D.It uses large read requests.

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 1 Gbps.
What would be the best solution for this network configuration?

• A.Use jumbo frames to compensate for the 1GB Core network.
• B.Aggregate Infiniband (IB) ports across all nodes.
• C.Use LACP to aggregate the network ports on each node.
• D.Bond EXT-0 across all nodes.

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

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?

• A.Five X400 (2 TB drives) nodes with SyncIQ.
• B.Five X400 (2 TB drives) nodes with SnapshotIQ.
• C.Seven X200 (3 TB drives) nodes with SyncIQ and SnapshotIQ
• D.Four NL400 (3 TB drives) nodes with SyncIQ.
