Check Free Updated DELL EMC DEE-1421 Sample Questions

1. A Dell EMC Isilon cluster replicates critical production data and long-term archive data from the data center to a target cluster. The source cluster runs OneFS 8.1.1 and the target cluster runs OneFS 7.2. OneFS will not be upgraded on the target cluster.

When the archived data on the source cluster is replicated to the target cluster, the capacity consumption on the source cluster far exceeds what is expected.

What is the reason for the increase in capacity consumption on the cluster?

2. A company has an existing Dell EMC 4-node X410 Gen 5 cluster with approximately 100TB of SMB shares connected using two InfiniBand 8-port switches. The company wants a technical refresh of the cluster with a new 4-node H500 Gen 6 cluster with two 16-port InfiniBand switches. The existing cluster has SyncIQ, SmartConnect Advanced, and SmartPools licenses installed.

To move the data from the existing modes to the new nodes, which migration plan is recommended?

3. A company has a medical application that generates a large number of media files. The file count is well over one billion and is stored on a Dell EMC Isilon 8-node NL410 cluster. Currently, each node is connected to the network using two 10GbE connections. The Linux-based application does not require high bandwidth; however, it is latency sensitive. Additionally, the Linux hosts are connected to the cluster over NFSv3. The application generates approximately 10,000 files every 10 minutes.

For the past four years, the cluster has been growing at a rate of one additional node per year. The company is running out of free ports on their redundant network switches. They want to know what can be done to ensure continuous availability. They do not want to invest in upgrading the network infrastructure. In addition, the company needs to reduce the number of consumed interface ports on the switches.

Which recommendation should be provided?

4. A company has a cluster with two subnets. The first subnet has 1 GbE interfaces dedicated for management and the second subnet has 10GbE interfaces dedicated for handling all data access. When the cluster started serving the production environment, poor performance was observed while the data is accesses through the data subnet. While troubleshooting the network, the administrator discovered that the return traffic is going through the management network.

Which recommended solution will resolve this issue?

5. Case Study 4

A company is experiencing a noticeable decrease in performance when accessing data on their Dell EMC Isilon cluster. The cluster hosts Microsoft Windows home directories and general purpose file shares. In addition, a file pool policy moves data that has not been modified in six months to an achieve tier. The administrator wants your assistance in understanding the reason for the slow data access. The number of users accessing the cluster has not changed.

The administrator has shared the following baseline metrics. The outputs were captured from a performance- acceptable time frame.



Trace route shows:

- 3 hops between clients and the cluster

- Average latency is 3 ms

Iperf shows:

- 940 Mb/s average bandwidth

- 005 ms average jitter

Netstat on the local network shows:

- 05% average re-transmission rate

Hostcache list:

- 20 ms average roundtrip time across all clients

The administrator shows the following traceroute output:

- 6 hops between clients and the cluster

- Average latency is 84 ms

Based on the output, what information should be provided the administrator?

6. What enables CloudPools to achieve a recall of data from the cloud?

7. You are assisting a company in planning for a Dell EMC Isilon disaster recovery site. One of the company’s concerts is the time that is needed for the initial synchronization between the primary and disaster recovery sites.

What will help address this concern?

Case Study 5 C 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?

9. A company plans to deploy N+2d:1n protection on a 7-node Dell EMC Isilon cluster.

How much capacity will be used to store a 1536 KB file?

10. A company has an environment with multiple AD forests in a one-way trust relationship. The AD provider on the cluster is configured with SFU. The trusted domains are failing to supply UIDs and GIDs to the Dell EMC Isilon cluster. As a result, users from the trusted domain are receiving an “access denied” error message.

What is a possible reason for the denial?

11. A Dell EMC Isilon administrator has reported that in Access zone “ProdZone” on the OneFS file system “nfs1”, Microsoft Windows “DEESuser1” has root level permission on nfs1. Use the “Launch Situation” button to examine the environment and validate the reason for this condition. Note: It is necessary to “close” (x) the simulation windows to answer the question.

Based on your findings, what is the reason for the condition?

12. A company uses the Dell EMC Isilon cluster’s A200 nodes for short-team archiving of digitized film. Historical and trending information shows that the cluster capacity will reach 90% full in 60 days. To avoid the need to purchase additional A200 nodes, the company requires a solution that archives data not accessed for 18 months to a more cost-effective platform. The long-term archive data must be online and accessible. Some performance loss is acceptable.

Which IT strategy provides a long-term solution that meets the requirements?

13. Case Study 3

A financial services company has file sharing workflows and 2000 home directories which include 70% Microsoft Windows and 30% Linux. The Security team is also interested in credit card usage data analytics such as point of sale, geolocation, and authorization and transaction data. Home directories and file shares do not require D@RE or SEC compliance.

However, due to the sensitivity of the credit card data, the company requires D@RE for credit card information and must adhere to the U.S. SEC 17a-4(f) compliance standards. Additionally, they are interested in auditing user access and anti-virus features.

The compute and storage environment consists of the following:

- 200 TB of Fibre Channel drives on NetApp ONTAP 7

- Environment is expected to grow 200 TB over the next three years

Which type of encryption is used in a D@RE-enabled Dell EMC Isilon cluster?

14. A company is migrating files from a third-party storage platform that is authenticated through AD. The migration tool being used is Dell EMC “EMCOPY.exe” running on a separate Microsoft Windows host. In order to run the EMCopy process and complete the migration, which type of account is required?

15. A company uses a Dell EMC Isilon cluster to store greater than one billion files. The company often restores files from NDMP backups.

Which backup technology is recommended for the environment?
