B. FICON

C. Infiniband

D. Fibre Channel

A customer has two data centers (Site A and Site B).There is an Isilon cluster in each data center and they use SyncIQ to replicate data between the two data centers.

You have reviewed their disaster recovery plan and found the following:

The policies specify that SyncIQ runs a replication job every 3 hours and that the job finishes within 1 hour.

Three additional hours will be needed to get servers and the network redirected to work from Site B.

What is the Recovery Point Objective in this plan?

A. 2 Hours

B. 3 Hours

C. 4 Hours

D. 5 Hours

-- Exhibit -A large manufacturing company is an existing Isilon customer with a cluster consisting of four NL400 nodes with 4TB drives. The cluster is using N+2:1 protection level and the file system shows that it is 60% utilized. Home directories and file shares comprise 75% of the existing content and the remainder is inactive deep archive. The company has 1,000 employees using Windows and Mac clients participating in a single Active Directory (AD) forest.

During a meeting with the CIO and Director of IT you discuss the company's recent acquisition ?an engineering firm that specializes in Computer Aided Design (CAD). The engineering firm has 400 UNIX workstations that produce technical drawings which are currently stored on another vendor's SAN solution. The all UNIX environment uses NIS for authentication and name resolution. They do not currently use DNS or LDAP. The engineering company has an old storage system that has been experiencing problems and the CIO would like you to migrate the data onto the Isilon cluster. The CIO would like to eliminate all tape and recover the data onto disk.

The CIO is concerned about security of the company's intellectual property, especially with the rapid adoption of mobile devices and external cloud content sharing services such as DropBox, Egnyte, and SugarSync. They would like to implement an alternative that provides external file sharing and mobile device synchronization while maintaining security control over the company's data.

The Director of IT reports that users are storing non-work related content on the Isilon cluster. They would like to limit the amount of capacity that each user can consume in their home directory and want to ensure you provide the capability to easily visualize which users are over their allotment.The company's Windows users currently leverage Windows Shadow Copy to recover files that have been accidentally deleted. The IT department wants to ensure that Mac and incoming UNIX clients have the same functionality.

The Director of IT also mentions that users are reporting slow response times when browsing their home directories and shared folders. They are concerned that Isilon cannot scale to support their combined requirements.

-- Exhibit -

What steps would you recommend to the IT Director to allow for collaboration between the engineering company and the manufacturing company?

A. Set up Access Zones on the Isilon cluster using Active Directory (AD) and NIS authentication. Create directories and apply user group permissions from AD and NIS for each collaboration team.

B. Repoint the engineering users to the Active Directory controller Add the users to the appropriate Active Directory security group.

C. Upload a collaboration user csv file into the cluster with usernames and passwords for the collaboration directory.

D. Create a new pool for use by the collaboration users. Set up Access Zones on the Isilon cluster using AD and NIS authentication.

If a file is 4 KB in size, how much space is consumed for file data when it is written to the Isilon cluster?

A. 4 KB

B. 8 KB

C. 16 KB

D. 32 KB

A customer is looking for a NAS solution to support their read-intensive application.

This solution must meet the following requirements: 1000 users Aggregate bandwidth of 5 GB/s 500 TB of user data Typical latency of 5 ms.

The files are distributed evenly across 10 directories.

Which cluster configuration would best meet these requirements?

A. Seven X400 (108 TB) nodes with no SSD

B. Eight NL400 (96 TB) nodes with 1.6 TB SSD

C. Eight X400 (96 TB) nodes with 1.6 TB SSD

D. Twenty-five X200 (30 TB) nodes with 800 GB SSD

A customer wants to replace a legacy storage environment used for high definition video editing. Each workstation connecting to the shared storage needs to sustain 650 MB/s of single stream bandwidth. Which node type is recommended?

A. Performance Accelerator nodes

B. NL-Series nodes

C. X-Series nodes

D. S-Series nodes

A system administrator has identified a problem on the cluster and has opened a service request on support.emc.com. They initiate isi_gather_info but it is taking a long time to complete. What can they do to speed up the completion of isi_gather_info for the next run?

A. Collect the required logs from the syslog server

B. Restart the CELOG daemon

C. Increase the speed of the network link

D. Exclude the specified tool(s) from being gathered

There is a need to carry out a tech refresh of an Isilon cluster. Old nodes must be removed because of space constrains in the data center. What methodology is least disruptive and will retain the file system structure, configuration, data, and DNS information?

A. Install the new nodes as a new cluster and use SyncIQ to replicate the data to the new nodes

B. Add the new nodes to the cluster and use SmartFail to move the data to the new nodes

C. Install new nodes into the cluster and use SyncIQ to replicate the data from the old to the new nodes

D. Install the new modes into the cluster and migrate using a host-based utility

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

A. Connection count and round robin

B. Round robin and CPU usage

C. Throughput and CPU usage

D. Throughput and connection count

What should be avoided when designing snapshot schedules?

A. Using aliases

B. Manual snapshot deletion

C. Running the SnapshotDelete job

D. Setting an expiration
