DEE-1421 Cluster Practice Questions

A company uses the Dell EMC Isilon cluster’s A200 nodes for short-term 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?

• AA. Use a CloudPools policy to move the target data to an ECS-powered cloud
• BB. Use NDMP to backup to disk using compression and deduplication
• CC. Use SyncIQ to replicate the archive to the H600 nodes on the secondary cluster
• DD. Use data deduplication on archived data not accessed within 180 days

The DobiMigrate used to migrate data from a third-party platform to a Dell EMC Isilon cluster. Less than 50 GB of NFS, SMB, and multi-protocol data will be migrated. What are the minimum requirements for the migration?

• AA. Core server and no proxy servers
• BB. Core server and one proxy server
• CC. Core server and two proxy servers
• DD. Core server and three proxy servers

An administrator wants to increase network throughput for an individual UNIX client when accessing a Dell EMC Isilon Gen 6 cluster. The administrator has configured the node interfaces to use LACP and has seen no increase in performance. Why is there no increase in client-to-cluster network performance?

• AA. Main purpose for LACP is to provide link redundancy
• BB. Network switch is using an incompatible version of LACP
• CC. Latency may occur as LACP requires extra CPU cycles
• DD. LACP increases performance for only the SMB protocol

A company has a Dell EMC Isilon Gen 5 cluster with SSDs in each node. The administrator notices that L3 Cache is enabled on the cluster. However, the administrator does not notice any performance increase for the read I/Os. After further investigations, the administrator discovers that all read I/Os are more than 128K chunks. Which recommendation should be provided to improve the read performance?

• AA. Enable Global Name Space acceleration in addition to L3 Cache
• BB. Change the SSD strategy to "data on SSD"
• CC. Disable L3 Cache and change the SSD strategy to 'metadata-read acceleration'
• DD. Add one more SSD of equal capacity to each node
