VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 22

An architect is designing a solution based on the following information:
✑ Each ESXi host has a single physical NIC with two 10 Gbps ports.
✑ There is a performance-based service-level agreement (SLA) that guarantees 15 Gbps bandwidth for production virtual machines at all times.
✑ There is no budget to purchase additional hardware.
✑ The hardware replacement SLA is based on a delivery agreement of two business days.
Which recommendation for the configuration of vSphere High Availability (HA) should the architect include in the design?

Answer options

• A. Configure vSphere HA Configure % based admission control Configure two isolation addresses Consider an OEM with NIC failure conditions in their Proactive HA plugin
• B. Configure vSphere HA Set das.IgnoreRedundantNetWarning to true Consider an OEM with NIC failure conditions in their Proactive HA plugin
• C. Configure vSphere HA Configure two existing data stores for heartbeat Consider an OEM with NIC failure conditions in their Proactive HA plugin
• D. Configure Proactive HA Automation Level: Automated Remediation: Maintenance mode for all failures Consider an OEM with NIC failure conditions in their Proactive HA plugin

Correct answer: D

Explanation

The correct answer is D because it ensures that all failures are managed through automated remediation, which is essential given the SLA requirements and hardware constraints. Options A, B, and C do not provide the necessary level of automation and proactive management needed to meet the SLA for production virtual machines, especially in a scenario with limited hardware resources.
