Exam 2V0-13.25 topic 1 question 14 discussion

by VMware’s own docs, C is more HA-critical than D. C (Host isolation response: Power Off and restart VM) – Explicit vSAN + VCF requirement; directly tied to HA.

Explanation D. Physical Switch MTU: 9000: Setting the physical switch MTU to 9000 (jumbo frames) is a physical design decision that improves network efficiency and performance for network-intensive traffic such as vSAN and vMotion. This enhances overall performance and reliability, contributing to the high availability of management components that rely on these networks. E. Management Port Group: Route based on physical NIC load: Configuring the management port group to use "Route based on physical NIC load" (or a similar NIC teaming policy like "Route based on IP hash" with LACP/EtherChannel configured on the physical switches) provides both load balancing and redundancy. If one physical NIC fails, traffic is automatically rerouted through the other NICs, ensuring continuous network connectivity and supporting the availability requirement.

D. Physical Switch MTU: 9000 Using jumbo frames (MTU 9000) improves network efficiency and reduces CPU overhead, especially for storage traffic like vSAN and vMotion. This enhances performance and reliability, contributing to high availability. E. Management Port Group: Route based on physical NIC load This NIC teaming policy provides load balancing and redundancy, ensuring that traffic is distributed across multiple physical NICs. If one NIC fails, traffic can continue on the others, supporting continuous availability.
