1. An administrator is investigating the performance of one of their Dell EMC Isilon clusters. Using the isi statistics drive command, the performance of the first five drives is shown.

Based on the exhibit, what represents the status of the drives?

I/O latency is approximately half a millisecond

Drives operate well within their estimated IOPS limits

I/Os are not queuing due to high latency

Drives exceed their estimated IOPS limits

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?

Enable WORM on the target directory after the initial synchronization.

Allow OneFS to create the target directory automatically.

Manually create target SmartLock directory before replicating.

Specify the “root” user that can delete files committed to a WORM state.

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?

3 for production and 7 for isolated

4 for production and 6 for isolated

4 for production and 7 for isolated

6 for production and 4 for isolated

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

Creating a HardLink file for every file whose data is archived to the cloud

Creating a SoftLink file for every file whose data is archived to the cloud

Creating a SmartLink file for every file whose data is achieved to the cloud

Creating a copy file for every file whose data is achieved to 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?

Create one NS record delegation per cluster. NS record should always point directly to the cluster SSIP address.

Create one NS record delegation per SmartConnect zone. NS record should always point to an “A” record containing the zone SSI

Create one NS record delegation per SmartConnect zone. NS record should always point directly to the SmartConnect zone IP address.

Create one NS record delegation per cluster. NS record should always point to an “A” record containing the cluster SSIP address.

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?

Use data deduplication on achieved data accessed within 180 days

Use SyncIQ to replicate the archive to the H600 nodes on the secondary cluster

Use NDMP to backup to disk using compression and deduplication

Use a CloudPools policy to move the target data to an ECS-powered cloud

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?

Two-way NDMP restore

Directory DAR

Three-way NDMP restore

Direct Access restore

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?

Leave the first four nodes of the cluster connected to both network switches with LACP and free up the remaining connections

Leave the first node of the cluster connected to both network switches and free up the remaining connections

Leave the first four nodes of the cluster connected to both network switches and free up the remaining connections

Leave the first 10GbE interface from each node connected to the same network switch and free up the remaining connections

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?

Replication is allowed but a failback will copy the entire dataset

SyncIQ will support a failback regardless of the target’s directory type.

Target directory must be a SmartLock enterprise type.

A SyncIQ policy is not supported on a WORM domain.

1792 KB

1920 KB

2048 KB

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?

admin1 is not the owner of the directory

admin1 only has read permission

admin1 is a member of the Domain Admin group

Deny ACE entry is listed first

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?

Setup a new cluster with the new Gen 6 nodes and its InfiniBand switches Use SyncIQ to migrate the data and then SmartFail the existing cluster

Setup a new cluster with the new Gen 6 nodes and its InfiniBand switches Use EMCopy to migrate the data and then use “sharedup” to create the shares

Modify the default file pool policy to move the data Swap the existing InfiniBand switches with the new switches

Add the new nodes to the existing cluster Modify the default file pool policy to move the data and then SmartFail the existing nodes

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”?

student only

root only

domain users

everyone

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?

Domain user account that is a member of the local Windows Backup Operators group on the source and target.

Domain user account created explicitly to use isi_vol_copy or isi_vol_copy_vnx on the source and target

Local user account that has permission to use the EMCOP

exe utility on the separate Windows host

Local user account that has members of the local Windows Backup Operators group and local Administrators group on the source and target.

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?

Enable TCP port 25 between all nodes and the SMTP server

Enable TCP port 443 between all nodes and the ESRS gateway

Edit and enable the Alert Channel for ConnectEMC

Ensure only the first cluster node is in the “allowed” list in Alert Channel settings.

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?

Use LACP active/active on the 10gige ports from each node to get more than 10GbE throughput

Enable SMBv3 multichannel functionality to get more than 10GbE throughput

Use LACP active/passive on the 10gige ports from each node to get more than 10GbE throughput.

Enable both SMBv3 multichannel functionality and LACP to get more than 10GbE throughput

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?

Non-transitive forest trust is required for cross domain lookups.

Transitive external two-way trust is required for cross domain lookups.

Non-transitive external two-way trust is required for cross domain lookups.

Transitive forest trust is required for cross domain lookups.

19. An administrator wants to increase network throughput for individual UNIX clients when accessing files on a Dell EMC Isilon Gen 6 cluster. The administrator has configured node interfaces to use LACP and has seen no increase in performance.

Why is there no increase in client-to-cluster network performance?

LACP increases performance for only the SMB protocol

Main purpose for LACP is to provide link redundancy

Network switch is using an incompatible version of LACP

Latency may occur as LACP requires extra CPU cycles

20. A company has purchased a new Dell EMC Isilon cluster as a disaster recovery solution and plans to use SyncIQ. SBR is not currently enabled. The systems administrator has asked for advice about how to configure the network connectivity for the replication traffic.

What are Dell EMC recommendations for a replication network configuration?

Create a separate replication subnet Do not configure a gateway for the subnet

Create a separate replication subnet Configure a gateway for the subnet

Configure a gateway for the replication subnet Configure a static route for the other side

Create a separate replication subnet Do not configure a static route for the other side

21. 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?

Leverage the ECS replication technology to replicate the archived data.

Starting OneFS 8.0, SyncIQ will replicate the data without retrieving it from EC

Select the Deep Copy option in the SyncIQ policies to replicate the archived data.

Upgrade the source cluster to OneFS 8.1.x to be able to replicate the archived data using SyncI

22. A media company has a Microsoft Windows-based infrastructure and uses Adobe media editing tools to create advertisements for its customers. Users from the Media Production department store all types of media files on a Dell EMC Isilon cluster.

In addition, users from the Support department are not allowed to store MP3 and AVI files to the NAS system. Both the Media Production and Support departments need to acces other common data on the cluster. Due to workflow procedures, the media files are stored on the same path on the Isilon cluster.

The company wants to know which Isilon features are available and can restrict the Support department users from writing certain media file types onto the Isilon cluster.

Which recommendation should be provided?

Create an SMB share for the Media Production department and restrict the Support department users from accessing the share. Create another SMB share for the Support department and apply file filtering.

Create an SMB share for the Support department and restrict the Media Production department users from accessing the share. Create another SMB share for the Media Production department and apply file filtering.

Create a separate Access zone for each department. Use SyncIQ to replicate the data and exclude the media files.

Create a single SMB share for both departments. Use the share security settings and Windows NTFS settings to restrict the file types.

23. A company is adding a 48-node A2000 with 10 TB HDDs for deep archival data to their existing Dell EMC Isilon cluster. The existing cluster consists of a 10-node X210 and an 8-node NL410.

What is the minimum recommended protection setting required for the A2000?
