Nutanix Exam NCS-Core Topic 1 Question 72 Discussion

Actual exam question for Nutanix's NCS-Core exam

Question #: 72
Topic #: 1

A consultant is deploying a new Nutanix cluster. The nodes have the following network interfaces.

2x 10G NICS

2x 25G NICS

The consultant is using the default virtual switch configurations for AHV. After creating 10 VMs, the consultant observes inconsistent network speeds from the VMs on the AHV host.

What should the consultant do to resolve this issue?

AConfigure load balancing on the virtual switch for both 106 and 25G interfaces.

BConfigure a separate virtual switch with 10G NICs on vs o and 256 NICs on vs.

CConfigure Active/Backup for both the 10G and 25G interfaces.

DConfigure all network interfaces with LACP on the same virtual switch.

Show Suggested Answer

Suggested Answer: D

To resolve inconsistent network speeds from the VMs on an AHV host equipped with both 10G and 25G NICs, the consultant should configure all network interfaces with Link Aggregation Control Protocol (LACP) on the same virtual switch. This configuration will allow for better load balancing and bandwidth aggregation across multiple network interfaces, improving overall network throughput and reducing bottlenecks. Reference:

D) Configure all network interfaces with LACP on the same virtual switch. This is the right answer, but I can't help but wonder if the consultant is using a Nutanix cluster or a box of donuts.

User 4: Let's focus on the networking issue at hand, though. LACP sounds like the way to go.

A) Configure load balancing on the virtual switch for both 106 and 25G interfaces. I think this is the most straightforward solution to distribute the traffic across the available network interfaces.

B) Configure a separate virtual switch with 10G NICs on vs o and 256 NICs on vs. This way, the VMs can utilize the higher bandwidth of the 25G interfaces.

C) Configure Active/Backup for both the 10G and 25G interfaces. This will ensure redundancy and failover, which is important for a production environment.

D) Configure all network interfaces with LACP on the same virtual switch. This will provide load balancing and failover for both the 10G and 25G interfaces, which should resolve the inconsistent network speeds.
