Question 53

Refer to the exhibit.

During a requirements gathering workshop, the architect shares the following diagram:

What should the architect recommend for guaranteed throughput for each service?

Use explicit failover order with pNIC0 as Active for ESXi Management and VM Network Use explicit failover order with pNIC1 as Active for backup network Use explicit failover order with pNIC2 as Active for vMotion Use explicit failover order with pNIC3 as Active for replication

Use the Route Based on IP Hash for ESXi management and VM network Use the Route Based on IP Hash for backup network Use the Route Based on the Originating Virtual Port for vMotion Use failover with pNIC3 as Active for replication

Create a link aggregation group (LAG) for vDS_01 Use the Route Based on Physical NIC Load for vMotion Use the Route Based on Physical NIC Load for replication

Use the Route Based on IP Hash for ESXi management and VM network Use failover with pNIC1 as Active for backup network Create a link aggregation group (LAG) for vDS_02

Correct Answer: A

Using explicit failover order allows for better control over which physical network interface card (pNIC) handles specific traffic types. This provides a clear and defined pathway for network traffic, making it possible to allocate bandwidth and ensure throughput for each service. Explicitly assigning pNIC0 to ESXi Management and VM Network, pNIC1 to the backup network, pNIC2 to vMotion, and pNIC3 to replication ensures that each service has dedicated resources, thereby guaranteeing throughput.

A: Use explicit failover order with pNIC0 as Active for ESXi Management and VM Network Use explicit failover order with pNIC1 as Active for backup network Use explicit failover order with pNIC2 as Active for vMotion Use explicit failover order with pNIC3 as Active for replication B/D: Can elimimate anything that says "Route Based on IP Hash" as there is no physical switch(s) in the digram to show Etherchannel Bonding C: Won't "guarantee" throughput

alein_Option: A

It is tricky. I think that A is correct. We must provide guaranteed throughput for each service, not maximum performance. VM network and backup is not a service, only VMotion, replication, management. The problem is that in A VM network and management is together. In this scenario backup and VM network should be together. From the load point of view, it makes sense, as backup can saturate 100% of NIC but it is not service. Poor question.

Answer is A " The problem is that in A VM network and management is together. In this scenario backup and VM network should be together. From the load point of view, it makes sense, as backup can saturate 100% of NIC but it is not service." Agree with that point. I consider that all data network or at least the most of that traffic will go through NSX - vDS_03

VCIX_ChrisOption: A

A, everything else requires settings on physiscal switches that are not in the diagram.

FR_WolfmanOption: A

Answer A. The other options won’t guarantee anything

bpexamOption: A

A will be correct
