NCS-Core Practice Test

A consultant needs to review a customer’s switch port configuration to identify any issues. Other customer requirements are as follows:

* Leverage LACP
* Native VLAN will not be used
* Use Multiple Upstream switches
* Use VLANs 20-25 and 30
* LACP Fallback has been Enabled
* vPC or MLAG has been configured

What must be included in a configuration in order to meet these requirements?

A. Native VLAN set to default Ports trucked to allow all necessary VLANs

B. Native VLAN set to default Ports in access mode to allow all necessary VLANs

C. Native VLAN set to 30 Ports Trunked to allow all necessary VLANs

D. Native VLAN set to 30 Ports in access mode to allow all necessary VLANs

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

B. 192.168.5.2

C. 192.168.5.254

D. 192.168.5.1

An administrator has a 32-node hybrid cluster with CPU, RAM and storage utilization of 80%. A database VM is configured with VM Flash. What is causing this IO latency?

A. Controller VM is experiencing high CPU ready time.

B. Curator scans causes by ILM constantly moving data.

C. VM Flash Mode reduces SSD tier capacity for VMs.

D. Database VM is experiencing high CPU ready time.

A customer has HE servers with DiscoverOS and wants to install a Nutanix cluster. Which method should a consultant use to meet the requirements?
