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?
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?
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?
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:
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 replication policies that are required to facilitate granular failover and failback capabilities for each AD domain?
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?
You have been asked to design a Dell EMC Isilon cluster running OneFS 8.x for a service provider. One of the most critical areas to the provider is data segregation with multi-tenants. Use the “Launch Simulator” button to identify the current condition of the cluster: Note: It is necessary to “close” (x) the simulator window to answer the question.
Based on your findings, what is the cluster’s current condition?

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 investigation, you notice that the backup job targets two paths. This could be the cause of the lengthy backup times.
What advice should be provided to the team?

How many tenant Access zones will be required?
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?
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?
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?
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?
Which protocol is used to send isi diagnostic gather logs from a Dell EMC Isilon cluster to Dell EMC Support when the ESRS gateway is unavailable?
