Q: 12
An architect is responsible for designing a VMware Cloud Foundation (VCF)-based private cloud for a
customer. During the customer requirements gathering workshop, the customer has stated the
following:
All Platinum applications/services must have an availability SLA of 99.99%.
All Gold applications/services must have an availability SLA of 99.9%.
All Silver applications/services must have an availability SLA of 99%.
The private cloud must have an availability SLA of 99.9%.
What should the architect recommend to meet the stated requirements?

C. exam reports and the official docs both say app layer is needed for higher SLA.
Option C here. Since the private cloud SLA is locked at 99.9%, you can't hit 99.99% from infra alone. Platinum apps need their own HA/resiliency at the app level to bridge that gap, that's why C makes sense to me. Pretty sure this matches how most of us have seen it explained.
C . Infra maxes out at 99.9% so Platinum app must handle its own HA to hit 99.99%.
Probably C here. Had something like this in a mock and infra can't guarantee more than its own SLA, so Platinum needs app-level HA for 99.99%. Not 100% if they reworded but that's what I remember.
C or D? Private cloud SLA is 99.9% so C looks right.
D infra Proactive HA should boost SLA enough for Platinum I think. Trap might be B here.
Not D, because Proactive HA on the infra can't make up that last .09%. C is better since app-level HA is the only way to get 99.99% when underlying cloud is capped at 99.9%. Some folks might pick D thinking infra can compensate, but that's a trap. Anyone see it differently?
I don't think D actually gets you to 99.99%, since the infra SLA caps out at 99.9%. Platinum apps need extra HA on their side-so C makes more sense here, not D.
Infra tops out at 99.9% so Platinum's 99.99% can't be met just by infrastructure tweaks like Proactive HA or multiple VCFs. Application-side HA is the only shot here imo, so C fits best. Open to other logic though.
C Proactive HA (D) sounds good but can't push infra above its SLA ceiling, so apps need built-in resilience to make 99.99%. Seen similar logic on other VCF practice sets. Disagree?
Be respectful. No spam.
