Question 37

A VCF architect collected the following requirements when designing the expansion of a new VI Workload Domain with twenty-four vSAN Ready nodes, each with a dual-port 25Gbps network interface card:

Provide scalable high-performance networking with layer-3 termination at top-of-rack

Protect workloads from switch/NIC/rack failure

Provide isolation for DMZ workloads

Provide at-least 25Gbps dedicated bandwidth to backup traffic

Easily accept workloads on traditional VLAN-backed networks

Fully-supported by VMware -

Which three design considerations meet all of these requirements? (Choose three.)

Core Aggregation network topology

Spine and Leaf network topology with layer-3 at top of rack

Two-node Edge Cluster with ECMP

Stretched Clustering

Spine and Leaf network topology with layer-3 at Spine

Two-node Edge Cluster with BFD

Correct Answer: B, C, F

To meet the requirements for scalability, high-performance networking, protection from failures, isolation for DMZ workloads, dedicated bandwidth, and full VMware support, the following design considerations are recommended: A Spine and Leaf network topology with layer-3 termination at the top of the rack ensures scalable high-performance networking. A two-node Edge Cluster with ECMP (Equal-Cost Multi-Path) provides redundancy and high availability, protecting workloads from failures. A two-node Edge Cluster with BFD (Bidirectional Forwarding Detection) further enhances the redundancy and fault-tolerance, meeting the requirement to protect workloads from switch/NIC/rack failure while being fully supported by VMware.

Discussion

DarkEngelOptions: BCF

COre aggregation and Spine and leaf together??? It is Spine and Leaf (B) Two Edges with ECMP and BFD (C&F)

AnBlueOptions: BDF

rack failure -> Stretched Cluster Spine Leaf Two Edge with BFD
