Question #: 2
Topic #: 1
Question #: 2
Topic #: 1
An architect is designing a VMware Cloud Foundation (VCF) Private Cloud. During a requirements gathering workshop, the customer supplied the following information:
* The solution must support the existing workloads.
* There are currently 10,000 virtual machine workloads running within the existing environment.
* All guest operating systems must be monitored by the solution.
* All infrastructure components must be monitored by the solution.
The solution must ensure that the 99.9% uptime Service Level Agreement can be met.
The solution must be resilient to a single-node failure.
The following logical design decisions have been made within the design:
* Deploy the VCF Operations cluster following the High Availability Model.
The following table is from the VCF Operations sizing guide:
Small
Medium
Single-Node Object Maximum
10,000
30,000
Single-Node Max Collected Metrics
1,600,000
5,000,000
Maximum Nodes in a cluster
2
8
Multi-Node Object Maximum
6,000
17,000
Multi-Node Max Collected Metrics
1,400,000
4,000,000
Maximum Objects in a Cluster
12,000
136,000
Maximum Metrics in a Cluster
2,800,000
32,000,000
Given the information above, which three physical design decisions meet the stated requirements? (Choose three.)
* The solution must support the existing workloads.

* All guest operating systems must be monitored by the solution.
* All infrastructure components must be monitored by the solution.

Given the information above, which three physical design decisions meet the stated requirements? (Choose three.)
Suggested Answer: A,B,C Vote an answer
The design must satisfy both monitoring capacity and single-node resiliency . C is correct because the solution already contains 10,000 virtual machines, and the requirement additionally includes monitoring guest operating systems and infrastructure components. A two-node Small configuration is unsuitable: the supplied sizing table limits a Small multi-node deployment to 12,000 objects and 2.8 million metrics , leaving insufficient practical headroom once guest OS and infrastructure monitoring objects are included. Three Medium nodes provide substantially greater object and metric capacity and support future operational growth.
B is required because the logical design explicitly specifies the VCF Operations High Availability Model .
Enabling VCF Operations HA provides application-level resilience by maintaining replicated analytics data so the Operations service can continue after failure of one cluster node.
A is also required because the VCF Operations nodes should be separated across ESX hosts. A DRS anti- affinity rule prevents multiple Operations nodes from running on the same physical host, ensuring that a single ESX host failure cannot simultaneously remove multiple Operations nodes.
D lacks adequate capacity and resilience headroom. E would intentionally colocate nodes and create a common failure domain. F is unnecessary because VCF Operations provides its own supported application- level HA mechanism.
