2. An IT team is preparing to replicate a dataset from their existing primary Dell EMC Isilon cluster to a secondary cluster. Both clusters are licensed for SmartLock Enterprise and SyncIQ is used for replication. The source directory is a SmartLock directory and the target directory must be a SmartLock directory.

When consulting with the IT team, what is a key consideration before running the replication policy?

3. A company has three Dell EMC Isilon X2000 nodes and needs to configure two subnets on the cluster. The production subnet will only use a 10 GigE-1 port from each node. The second subnet will use both ext-1 and ext-2 ports on each node. The company will access each subnet with its SmartConnect zone name.

Given that the second subnet is isolated with no route to the DNS server, how many IP addresses are needed for each subnet to accommodate the requirements?

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

5. SyncIQ policies are being configured between two Dell EMC Isilon clusters at a company’s location. In addition, the company wants the ability to perform a failover at an Access zone level.

Which actions should be performed to meet the requirement?

6. 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?

7. 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?

8. A company is planning to replicate a dataset to a newly implemented Dell EMC Isilon cluster. SyncIQ will be used from the source cluster to the target cluster. The company’s systems administrator wants to know how long the initial synchronization will take without seeding.

The administrator provides the following information:

- Link speed between clusters is 1 Gb/s

- Link speed efficiency is 85%

- SyncIQ domain size is 125TB

If no SyncIQ performance rules are set, what is the estimated number of days?

9. 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?

10. An IT team is implemented a disaster recovery solution. A Dell EMC Isilon cluster will replicate production data from the existing primary cluster to a planned secondary cluster. The primary cluster is licensed for SmartLock Enterprise. A SmartLock enterprise type directory on the primary cluster is planned for SyncIQ replication to the secondary cluster.

When consulting with the IT team.

What is a key consideration when replacing the data in a SyncIQ source directory configured with SmartLock Enterprise mode?

11. 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?

12. You are working with a company to migrate from a Microsoft Windows file server to a Dell EMC Isilon cluster using the account “admin1” in the “Domain Admin” group. When opening a directory, you receive an error message stating “permission denied”. You check the permissions and see that Domain Users are denied, Domain Admin has Full Control, and admin1 has read permission.

Why is the access denied?

13. 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?

14. A Dell EMC Isilon administrator has set up security on a share as shown in the exhibit.

Users in the group entitled “domain users” should only be allowed read access to the share.

Which user or group is able to only read from the share called “test”?

15. 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?

16. You have just configured a Dell EMC Isilon cluster. One of the remaining tasks is to enable alert notification. The cluster is on a network segment behind a firewall for security. You have determined which node is the CELOG master and have enabled connectivity between it and the ESRS gateway.

Testing shows that alerts were working for several days but have suddenly stopped.

Which action is required to resolve this issue?

17. A Microsoft Windows administrator has an environment that includes a 4-node Dell EMC Isilon H500 cluster with one subnet and two pools. The administrator will use SMBv3 in all their clients. One pool is for production using 10gige- 1 and 10gige-2 ports from each node. The other pool is for management using mgmt-1 from each node.

One of the concerns is the network throughput and how the administrator can get more than 10GbE throughput on the production pool on each node.

Which recommendation should be provided?

18. 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?
