EMC Dell PowerScale Design v2 Sample Questions:
1. What are two SyncIQ performance rules that help manage resource usage during scheduled events?
A) Throughput and Redirector
B) Worker and Throttler
C) CPU and Redirector
D) Worker and CPU
2. Your customer's initial use case was Home Directories. They implemented the cluster with four 1Gbps ports and LACP. They are planning to expand their cluster to support their core file services. They plan to upgrade their network infrastructure to 10 GbE to facilitate this.
What are two design impacts this change will have?
A) Maximum performance is obtained by only using a single 10GbE interface per node. Isilon can support up to 400MB/s per node
B) Dual 10GbE ports on each node will enable throughput of 20Gbps. Only connect half of the nodes to the network.
C) LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system. FCoE should be considered for the External Network Ports on the nodes.
D) Maximum performance is obtained by only using a single 10GbE interface per node. LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system.
3. A customer wants to use their large Gen 6 Isilon cluster for ILM. All of their data is written to and read from a single file pool. They need to use multiple file pools, so slightly used data is stored on less expensive, large disks. Heavily used data is stored on a faster tier.
What would satisfy the customer's needs?
A) Enable FAST VP license on each node pair
B) Add an A-series node with SmartPools license
C) Configure SmartPools Advanced
D) Install SmartPools license on the cluster
4. Refer to the exhibit.
A large hospital chain has approached you to redesign their storage infrastructure. The head of IT believes their requirement is for 60 TB of RAW capacity. The following are the notes from meetings with the department heads. Which is the minimum cluster configuration that meets the customer's requirements?
A) 4 X-Series Nodes using SynqIQ to 4 NL-Series Nodes
B) 5 S-Series Nodes
C) 3 S-Series Nodes using SmartPools and 3 NL-Series Nodes for Archive
D) 3 NL-Series Nodes using SynqIQ to 3 NL-Series Nodes
5. A PowerScale administrator has a cluster containing four F600 nodes. They must configure FTP connections for anonymous access that requires no authentication.
What is the result of this configuration?
A) The limit is 200 FTP connections per cluster.
B) The limit is 500 FTP connections per node.
C) The limit is 200 for FTP connections per node.
D) The limit is 500 for FTP connections per cluster.
