Question 8

A customer has requested help deploying a small single-VM instance of Prism Central in their environment that will be used for managing less than 100 guest VMs and registered to a single 5-node cluster. Due to business needs, the customer also plans to consume additional service features within the PC platform.
The consultant discusses with the customer and ultimately decides to deploy a small 3-VM instance to better account for possible resource overhead required once the additional services are enabled on the cluster.
The additional services the consultant must enable to meet the customer's requests are as follows:
*Nutanix Disaster Recovery
*MS-SQL Server Monitonng
*Flow Microsegmentation
Why won't the plan to deploy a small PC instance work for this customer?

A. Flow Microsegmentation requires an X-Large 5-VM scale-out instance of Prism Central be deployed in order to avoid constraints.

B. The additional services the customer needs cannot be supported on a small sized PC. Consultant must deploy at a minimum a large size PC.

C. The consultant must specify during the small PC deployment that all 3 PCVMs are configured to have
32GB of memory in order to ensure adequate overhead.

D. MS-SQL Server Monitoring requires additional licensing and a separate appliance to be deployed when using a small sized PC.

Question 9

A customer has provided the following network requirements to their consultant during a discovery session for AHV cluster deployments:
*Maximum Uptime Guest Traffic is a Hard Requirement
*Maximum Throughput for Guest is a Hard Requirement
*Link Aggregation is established at the TORs
Cluster nodes have the following network card configurations:
*2 x 40GbE Adapters
*2 x IGbE Adapters
How should the consultant satisfy these requirements?

A. Bonded 2 x 40GbE Adapters with LACP Disabled for Storage Traffic and bonded 2x1 GbE Adapters for Guest VM Traffic using active-backup

B. Bonded 2 x 40GbE Adapters with LACP Disabled for Storage Traffic and Guest Traffic using balance- sib

C. Bonded 2 x 1 GbE Adapters with LACP Enabled for Storage Traffic and Bonded 2 x 40 GbE Adapters for Guest VM Traffic using balance-tcp

D. Bonded 2 x 40GbE Adapters with LACP Enabled for Storage Traffic and Guest Traffic using balance- tcp

Question 11

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 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
