Questions # 1:

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?

Options:

A.

Leverage the ECS replication technology to replicate the archived data.


B.

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


C.

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


D.

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

Questions # 2:

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?

Options:

A.

Create one NS record delegation per cluster.

NS record should always point directly to the cluster SSIP address.


B.

Create one NS record delegation per SmartConnect zone.

NS record should always point to an “A” record containing the zone SSIP.


C.

Create one NS record delegation per SmartConnect zone.

NS record should always point directly to the SmartConnect zone IP address.


D.

Create one NS record delegation per cluster.

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

Questions # 3:

A company’s HPC environment is using Dell EMC Isilon Gen 6 nodes. They have additional throughput requirements and have asked for your recommendations. The environment consists of two subnets:

    Mgmt-subnet: 1x1-GigE interface in the “mgmt-pool” for management traffic on a VLAN-tagged management network in an Isilon default System Access zone.

    Data-subnet: 2x10-GigE aggregated interfaces in the “data-pool” for data traffic on a VLAN-tagged data network in an Isilon user-defined data Access Zone

Which recommendation should be provided?

Options:

A.

Use different groupnets for management and data traffic


B.

Move the data pool into the System Access zone


C.

Remove VLAN tagging from the network


D.

Use only one subnet and pool for both the management and data traffic.


Expert Solution
Questions # 4:

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?

Options:

A.

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.


B.

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.


C.

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


D.

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


Expert Solution
Questions # 5:

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?

Options:

A.

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


B.

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


C.

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


D.

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


Expert Solution
Questions # 6:

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?

Options:

A.

Create a separate replication subnet

Do not configure a gateway for the subnet


B.

Create a separate replication subnet

Configure a gateway for the subnet


C.

Configure a gateway for the replication subnet

Configure a static route for the other side


D.

Create a separate replication subnet

Do not configure a static route for the other side


Expert Solution
Questions # 7:

A Dell EMC Isilon administrator has reported that in Access zone “ProdZone” on the OneFS file system “nfs1”, Microsoft Windows “DEES\user1” 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?

Question # 7

Question # 7

Options:

A.

RFC-2307 has been enabled


B.

NFS Export settings has been set


C.

Active Directory has not been added to the Access Zone


D.

User mapping rule has been created


Expert Solution
Questions # 8:

A company has a Dell EMC Isilon cluster that will be used for a large amount of client requests. SmartConnect has been configured to help load balance the clients across the cluster. How does SmartConnect help the load balancing?

Options:

A.

Forwarding DNS requests.


B.

Caching lookup requests.


C.

Directing the connections to different nodes.


D.

Dynamically updating changes to DNS.


Expert Solution
Questions # 9:

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?

Question # 9

Options:

A.

I/O latency is approximately half a millisecond


B.

Drives operate well within their estimated IOPS limits


C.

I/Os are not queuing due to high latency


D.

Drives exceed their estimated IOPS limits


Expert Solution
Questions # 10:

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?

Options:

A.

Use data deduplication on achieved data accessed within 180 days


B.

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


C.

Use NDMP to backup to disk using compression and deduplication


D.

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