Question # 11

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.LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system

B.

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.

C.

Dual 10GbE ports on each node will enable throughput of 20Gbps.Only connect half of the nodes to the network.

D.

Maximum performance is obtained by only using a single 10GbE interface per node.Isilon can support up to 400MB/s per node

Question # 12

Question # 13

For concurrent I/O, how do SmartCache and Endurant Cache differ?

B.

Endurant Cache waits for acknowledgement from all nodes before copying to L2 cache

C.

SmartCache immediately commits the write to NVRAM on the local node and one peer node

D.

SmartCache uses sub-file, granular locking whereas Endurant Cache locks the entire file

NTP service takes precedence over SMB time sync

SMB time is enabled by default on the cluster

Best Practice: do not use NTP time, use SMB for cluster and Domain Controller

C.

NTP service takes precedence over SMB time sync

SMB time is enabled by default on the cluster

Best Practice: do not use SMB time, use NTP for cluster and Domain Controller

D.

SMB time sync takes precedence over the NTP service
