A new Nutanix customer suspects that network traffic is going over the 1G interfaces instead of the 10G interfaces.
How should a consultant confirm that the traffic is only traversing the 10G interfaces?
Answer : B
To confirm that network traffic is traversing the 10G interfaces and not the 1G interfaces in a Nutanix environment, the consultant should run the allssh manage_ovs show interfaces command. This command allows for the inspection of all interface configurations and their current operational status across the cluster, effectively confirming which interfaces are actively managing traffic.

Which Nutanix tool does the Field Installation Guide provide instructions for?
Answer : B
The Nutanix Field Installation Guide primarily provides instructions for using Foundation. Foundation is the tool used for deploying, imaging, and configuring Nutanix nodes in a new installation or when expanding existing clusters. This tool is essential for setting up the Nutanix environment correctly and efficiently. Reference:

For a new AHV cluster installation, a customer has 20 NX-8155 nodes with quad port NICs. The customer wants to meet the following guidelines:
Take advantage of all available 10G links
Achieve maximum throughput per VM
Use of redundant ToR switches
Fastest reconvergence during link failure
How should the load balancing be configured on the host?
Answer : D
For a configuration that aims to utilize all available 10G links, achieve maximum throughput per VM, and ensure redundancy with fast reconvergence during link failure, the optimal setting would be to configure Balance-TCP on bridge br0. This setting distributes the load across all available network paths based on the TCP session, maximizing the utilization of network interfaces and ensuring redundancy. This approach is particularly effective in environments with multiple network paths and ensures efficient network traffic management. Reference:

A consultant successfully creates a Nutanix cluster. The consultant needs to configure containers for the customers business critical applications and general server workloads. The customer requirements are to achieve maximum storage space savings and optimize
I/O performance.
What setting(s) should the consultant enable on the storage container(s)?
Answer : C
To meet the requirements of maximizing storage space savings while optimizing I/O performance for business-critical applications and general server workloads, enabling both compression and erasure coding on the storage containers is recommended. Compression reduces the data footprint on storage disks, while erasure coding provides data redundancy in an efficient manner, which not only saves space but also enhances data durability and I/O performance for read-intensive applications.

A customer has HE servers with DiscoverOS and wants to install a Nutanix cluster.
Which method should a consultant use to meet the requirements?
Answer : C
When installing a Nutanix cluster on hardware servers pre-loaded with an existing operating system such as DiscoverOS, the best approach is to re-image the bare metal nodes. This process involves using the Nutanix Foundation tool to install the required Nutanix software (such as AOS and Hypervisor) onto the nodes, replacing any pre-existing software. This ensures that the hardware is properly configured and optimized for the Nutanix environment. Reference:
