VCDX-DCV Sample Questions

  1. Question 1

    Intermediate

    Customer Requirements · Requirements Gathering and Stakeholder Engagement

    During a requirements gathering workshop for a financial institution, the CISO states that all data at rest must be encrypted using FIPS 140-2 validated modules. The Infrastructure Director mentions that the current storage array does not support native encryption but cannot be replaced due to budget constraints. How should this requirement be classified in the design documentation?

    Answer and explanation

    Correct answer: A

    This situation represents a conflict between a business requirement (encryption) and a constraint (budget/legacy hardware). In VCDX methodology, the inability to replace hardware is a hard constraint. The design must satisfy the requirement within this constraint, likely by implementing vSphere VM Encryption or Guest OS encryption, rather than array-based encryption.

  2. Question 2

    Intermediate

    Customer Requirements · Recoverability Requirements

    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?

    Answer and explanation

    Correct answer: B

    vSphere Replication can support RPOs as low as 5 minutes. Given the 100ms latency, synchronous replication (like vSAN Stretched Cluster) is not viable as it generally requires <5ms latency. vSphere Replication is asynchronous and suitable for this RPO and latency profile.

  3. Question 3

    Intermediate

    Customer Requirements · Requirements Gathering and Stakeholder Engagement

    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?

    Answer and explanation

    Correct answer: B

    Since the budget is not currently funded/guaranteed, the design must proceed based on the Assumption that the customer will secure funding to meet their stated growth requirement when the time comes. This protects the architect if future expansion fails due to lack of funds.

  4. Question 4

    Advanced

    Customer Requirements · Performance Requirements

    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?

    Answer and explanation

    Correct answer: C

    Resource Pools with Reservations allow the provider to logically partition a single cluster. By setting a reservation, the provider guarantees physical RAM/CPU resources to a tenant, effectively dedicating those resources within a shared management construct.

  5. Question 5

    Intermediate

    Customer Requirements · Availability Requirements

    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?

    Answer and explanation

    Correct answer: B

    99.99% availability (Four Nines) allows for approximately 52.56 minutes of downtime per year. (365 days * 24 hours * 60 minutes = 525,600 minutes. 0.01% of that is ~52.56 minutes).

  6. Question 6

    Advanced

    Solution Architecture · Complete Solution Design and Documentation

    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?

    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
    Answer and explanation

    Correct answer: D

    A conceptual design maps requirements to high-level components. To progress to a Logical design (which defines how components interact), the replication relationship (the dotted line) must be defined by requirements (RPO/RTO) and selected technology (async vs sync). Without defining the replication method/SLA, the logical design cannot be constructed.
