Question
An architect is tasked with expanding an existing VMware software-defined data center (SDDC) solution so that it can be used to deliver a virtual desktop infrastructure (VDI) service off-shore development activities. The production environment is currently delivered across two geographically dispersed data centers. The two data centers are currently connected to each other through multiple diversely routed, high bandwidth and low latency links. The current operations management components are deployed to a dedicated management cluster that is configured with N+1 redundancy. The current VMware software-defined data center (SDDC) has a monthly availability target of 99.5%, which includes all management components. The customer requires that the new solution scale to support the concurrent running of 500 persistent virtual desktops. The virtual desktops must not share the same virtual infrastructure as existing virtual machines, but can be managed using the same VMware operations management components. Any new VDI service management components must be installed into the management cluster. There is no requirement to back up the virtual desktops because all relevant user data is stored centrally. The VDI service is providing business critical services and must have an availability target of 99.9%. Given the information from the customer, which two assumptions would the architect include in the design- (Choose two.)
Options
- AThe existing virtual infrastructure has sufficient capacity to host the new VDI workloads
- BThe existing operations monitoring tools have sufficient capacity to monitor the new VDI services
- CThe existing management cluster has enough available capacity to host any VDI service
- DThe management cluster has N+1 redundancy
- EThe VDI service has a higher service-level agreement (SLA) than the operations management

Explanation
Options B and C are correct because they represent genuine gaps in the provided information - facts the architect must assume since no data was given to confirm them. The question states that existing VMware operations management components can be used for VDI, but provides no capacity metrics for those monitoring tools (B) or the management cluster's available headroom (C). Without this data, the architect must document these as assumptions, which is standard design practice.
Why the distractors are wrong:
- A is incorrect because the question explicitly states VDI workloads must not share existing virtual infrastructure - so assuming they could fit there contradicts a hard requirement.
- D is a stated fact, not an assumption - the question directly tells us the management cluster is configured with N+1 redundancy.
- E is also derivable from given facts - the VDI SLA (99.9%) vs. SDDC SLA (99.5%) is directly stated, making this a known condition, not an assumption.
Memory tip: In VMware design questions, distinguish between facts (explicitly stated), requirements (customer mandates), and assumptions (gaps where no data was provided). Assumptions fill information voids - if the question tells you something, it can't also be an assumption.
