Free EMC DEE-1421 Exam Dumps Questions & Answers

A Dell EMC Isilon administrator has a 6-node X400 cluster. As the hardware is approaching end of service life, the administrator has planned for a technical refresh by replacing the 6-node X400 cluster with a 4-node H500 cluster.
The new 4-node H500 is added to the existing cluster and a SmartPools trial license is activated for data migration. The default location for the data and snapshots is changed in the default file pool policy from an X400 node pool to a H500 node pool. The SmartPool job is then run manually.
After the SmartPool job is finished, the X400 node pool still consumes approximately 10% of the storage.
What is a possible reason for this issue?

• A.  Manually-managed files and directories still exist
• B.  SmartPool job finished with errors. Dell EMC Support needs to be contacted
• C.  SyncIQ migration method should have been used
• D.  SmartPools mat license is not sufficient, a W license a required

A company has an 8-node X410 installed as a single Dell EMC Isilon cluster. The company expressed concerns about cluster performance, particularly about NFS being slow. The output shown in the exhibit was presented to the Dell EMC technician.
Based on this output, what is a reason for the cluster performance issue?

• A.  SmartConnect is not properly balancing the connections
• B.  Number of I/O for a single node is too high
• C.  Too many namespace_read operations against the cluster
• D.  Average NFSv3 write latency is too high

A company has two Dell EMC Isilon clusters.
The source cluster is running OneFS 8.0.x and the target cluster is running OneFS 7.2.x with replication policies configured from the source to the target cluster.
OneFS will not be upgraded on the target cluster.
After some time, the company decided to archive some of the data to ECS using CloudPools.
One of the company's concerns is how the archived data will be replicated using the existing SyncIQ policies.
What is recommended approach to address the company's concerns?

• A.  Leverage the ECS replication technology to replicate the archived data
• B.  Selectthe Deep Copy option in thfl SynclQ policies to replicate the archived day
• C.  Starts OneFS 8 0. SynIQ will replicate the data without retrievingit fom ECS
• D.  Upgrade the sourcecluster to OneFS 8 1 x to be able to replicate the archived data using SynclQ

Case Study 1
A company has several independent business units that operate globally. The company has consolidated its IT infrastructure services and operations. Common infrastructural services which include IPAM, DNS, NTP, DHCP, and SMTP have been consolidated. The company has complimented its infrastructure development by investing in Dell EMC Isilon clusters to host its user's home and group directories and for compliance archival purposes required by individual business units.
The IT operations are located in India and the United States with its primary data center facilities co-located between New York and Texas. The company has a total of 60 AD forests:
* 1 main domain
* 55 domains have one-way trust relationships with the main domain
* An additional 4 domains do not have any trust relationship with no future plans of establishing trust relationships with the other domains.
Users of different AD domains use different FQDN to access their corresponding file services. Additionally, the company does not plan to consolidate the AD domains and each domain uses a different IP subnet. The users of the domains with no trust relationships have a compliance archival requirement. The company wants to all data to be replicated between New York and Texas.
What is the minimum number of groupnets required?

• A.  2
• B.  5
• C.  9
• D.  1

Case Study 5- Refer to the Exhibit.
Backing up data from a Dell EMC Isilon cluster exceeds the company's backup window. Because the company has a large amount of data with a continuous high growth rate, they want to change their backup strategy. The Gen 6 Isilon cluster consists of 24 nodes. Their current backup strategy is an NDMP three-way backup performing weekly full backups to tape and incremental backups each night. The strategy uses Dell EMC NetWorker. The DMA uses Include paths to specify what data to backup. All data on the cluster must remain accessible.
The company's IT team is now looking for a method to increase the performance of their backups. After some investigations, you notice that the backup job quiesces the file system. This is creating lock contention issues on open files and not allowing users full access to data when the backup job runs.
What advice should be provided to the team to eliminate lock contention and allow full access to users?

• A.  Add A100 Backup Accelerators and configure for three-way NDMP
• B.  Enhance the backup strategy using snapshots tor backups
• C.  Stop using an NDMP-based backup strategy
• D.  Create a cron job to remove alllocks before each backup
