• Question 97:

  An administrator is supporting a business critical environment and deploys metro availability to achieve a zero data loss configuration. The two clusters are connected by a 1GbE connection. A new workload is going to be deployed to this cluster. This workload requires a sustained 150MB/S of write throughput and 20MB/s of read throughput. Which change must be made to deploy the workload successfully on this cluster?

  A. The bandwidth must be increased to support this workload.

  B. The workload must be configured to read at greater than 12.5MB/S.

  C. The replication frequency must be less than 60 minutes.

  D. Zero data loss nearsync must be used to support this workload.

  Correct Answer: A

  Explanation: Ref:

  

• Question 98:

  An administrator is trying to correct high cluster IOPs and Cluster Controller Latency. Networking is the suspected issue.

  Which networking parameters should be configured in the Nutanix cluster?

  A. Bond State and network latency

  B. Number of NICs connected and network latency.

  C. Number of NICs connected and frame size

  D. Number of NICs connected and bond state.

  Correct Answer: C

• Question 99:

  An administrator is planning to deploy a Nutanix cluster to support a few high-performance VMs. This deployment will have the following considerations:

  Individual VMs will likely generate network throughputs in the range of 90-100Mbps Due to the configuration of the VMs, it is unlikely that a node will host more than one or two of them at a time Individual VMs will communicate with only a few (one or two) remote hosts at a time Multicast will not be used in the environment The hosts are connected via two 1GbE network connections

  How should the administrator configure the network bonds to meet this requirement while maintaining the simplest switch configuration?

  A. Configure bond0 as balance-sib

  B. Configure bond0 as active-backup

  C. Configure bond0 as balance-tcp

  D. Configure bond0 as balance-lacp

  Correct Answer: A

• Question 100:

  An administrator inherits a new Nutanix environment and logs in to a CVM to check the network configuration. The configuration is as follows: Which action should the administrator take to improve network performance?

  

  A. Configure VLAN tagging both on br0 and br1 and their physical interfaces.

  B. Add eth0 and eth1 to the br0-up bond

  C. Configure balance-sib or balance-tcp mode for br0-up if switch configuration allows

  D. Remove one 10 Gbs interface from br0-up to make sure all 10 Gbs can be used.

  Correct Answer: C
