EMC E20-555 Online Questions & Answers

• Question 111:

  What is used to set permissions for ESRS-managed devices?

  A. Policy Manager
  B. InsightIQ
  C. ESRS gateway
  D. SupportIQ
  A. Policy Manager

• Question 112:

  Refer to the exhibit.

  

  A customer calls you and asks if you could come by and interpret their InsightIQ data. You see that namespace reads are 63% of the work load. What would you recommend to help this cluster's namespace performance?

  A. Add SSDs
  B. Add A-Series nodes
  C. Add S-Series nodes
  D. Turn off write cache
  A. Add SSDs

• Question 113:

  An Isilon customer is reporting less than expected performance from the cluster and poor space utilization. The customer is using three X400 nodes with N+2:1 protection policy to host webserver log data. Upon further analysis, it is discovered that the webservers write log files 64 KiB in size. The log files are then accessed by an analytics application for reporting.

  What should be done to increase write performance of the cluster?

  A. Change the protection scheme to a mirroring policy.
  B. Add A-Series performance accelerator nodes to the cluster.
  C. Add S-Series storage nodes to the cluster.
  D. Add SSDs to the X-Series nodes in the cluster.
  A. Change the protection scheme to a mirroring policy.

• Question 114:

  A customer wants an N+3 protection level on their cluster. What is the minimum number of nodes they need to achieve that level of protection?

  A. 3
  B. 6
  C. 7
  D. 8
  C. 7

• Question 115:

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

• Question 116:

  When conducting high-level interviews with stakeholders of a project, what are the key questions that should be asked?

  A. How much usable storage are you looking for? What client OS will access this storage? Which applications will access this storage?
  B. Which backup application is in use today? What is your change rate? How many clients will connect to the cluster?
  C. What does your network architecture look like Do you have existing NAS infrastructure? Do you have 10Gb or 1Gb Which applications will access this storage?
  D. Who are the application owners? How much usable storage is needed? What applications will be accessing the storage? How many users are in your Active Directory?
  A. How much usable storage are you looking for? What client OS will access this storage? Which applications will access this storage?

• Question 117:

  What replication option is NOT supported by SyncIQ?

  A. Within the same local cluster
  B. Across WAN to single remote cluster
  C. Across InfiniBand to secondary local cluster
  D. Across LAN to secondary local cluster
  C. Across InfiniBand to secondary local cluster

• Question 118:

  A customer has two Isilon clusters. Cluster 1 has eight H500 nodes and cluster 2 has twelve H500 nodes. The customer needs to be able to monitor real time performance data of the clusters as well as track file growth. Which supported tool should be recommended?

  A. InsightIQ
  B. Data Insights
  C. Unisphere
  D. isi statistics
  A. InsightIQ

• Question 119:

  A customer has an Isilon cluster with 6 nodes and a single 4-core CPU per node. The default configuration for SyncIQ workers per CPU core and SyncIQ workers per node per job limits are used. How many SyncIQ workers are available for the Isilon cluster?

  B. 64
  C. 96
  D. 192
  B. 64

• Question 120:

  Traditional NAS storage architecture deploys simple two-way failover between two controllers in their storage systems, such as highly-available configurations. How is the Isilon architecture different in terms of system resiliency and availability?

  A. Isilon OneFS enables each node to have a designated partner node for simple failover between the pair.
  B. Isilon solutions can enable failover to other nodes with the use of client-side drivers.
  C. Isilon clustered architecture deploys standby failover nodes to ensure the highest available solution.
  D. Isilon OneFS enables each node to be a peer to any other node in an Isilon cluster.
  D. Isilon OneFS enables each node to be a peer to any other node in an Isilon cluster.
