VCDX-DCV sample questions

Question 1

An architect is designing a vSphere 8.0 solution. The customer requires a Recovery Point Objective (RPO) of 5 minutes for their Tier 1 database workloads. The primary and secondary sites are connected via a WAN link with 100ms round-trip latency. Which replication technology is the most appropriate architectural choice to meet this requirement?

Accepted Answer

vSphere Replication

Answer

vCenter HA

Answer

Array-based Synchronous Replication

Answer

vSAN Stretched Cluster

Question 2

A customer requests a design for a new virtual desktop infrastructure (VDI). They state, 'We expect to grow by 20% annually.' However, they cannot provide historical data or a funded budget for expansion. How should the architect document this in the design?

Accepted Answer

As an Assumption that budget will be available when growth occurs

Answer

As a Design Constraint affecting scalability

Answer

As a Functional Requirement for 20% spare capacity day one

Answer

As a Risk that the project will fail immediately

Question 3

A Service Provider requires a multi-tenant design where tenants must have dedicated compute resources that cannot be shared with others, yet the provider wants to manage a single large cluster to maximize operational efficiency. Which vSphere feature best addresses this specific requirement?

Accepted Answer

Resource Pools with Reservations

Answer

Storage I/O Control (SIOC)

Answer

vSphere High Availability (HA)

Answer

Affinity Rules (VM-Host)

Question 4

In a design interview, a stakeholder mentions, 'We need the system to be up 99.99% of the time.' The architect calculates the allowable downtime per year to validate this SLA. What is the approximate allowable downtime for 99.99% availability?

Accepted Answer

52 minutes

Answer

5 minutes

Answer

8 hours

Answer

1.5 days

Question 5

Analyze the following Conceptual Design diagram showing a proposed multi-site architecture. Based on the VCDX methodology, which critical element is missing that is required to map this concept to a Logical Design?

```mermaid
graph LR
Users((Users)) --> LB[Load Balancer]
LB --> Web[Web Tier]
Web --> App[App Tier]
App --> DB[(Database)]

subgraph Site A
Web
App
DB
end

subgraph Site B
DR_Web[Web Tier]
DR_App[App Tier]
DR_DB[(Database)]
end

DB -.->|Replication?| DR_DB
```

Accepted Answer

Definition of the replication method and RPO/RTO requirements

Answer

List of user accounts accessing the system

Answer

Specific hardware models for the servers

Answer

IP address schema for the subnets

Question 6

Which TWO of the following statements correctly distinguish a Constraint from a Requirement in a VCDX design scenario? (Select TWO)

Accepted Answer

A Requirement describes what the system must do; a Constraint limits how the system can be built.

Accepted Answer

Constraints are non-negotiable limitations imposed by the client or environment.

Answer

A Requirement is a risk that has not been mitigated.

Answer

A Constraint is always technical, whereas a Requirement is always business-focused.
