Questions # 7:

A consultant is setting up a new install of Nutanix Files for a customer, but receives this error when attempting to join the customer's Active Directory domain:

File Server could not join the Domain because User credentials failed with error Unable to connect to WORKGROUP ads_connect: No logon servers

The consultant has already verified the domain credentials provided by the customer are valid and have the correct permissions.

What is the most likely cause in this scenario for a domain-join failure when setting up Nutanix Files?

Options:

A.

The FSVMs storage network must be in the same network as the logon servers.


B.

The client network is failing to communicate with the customer's domain controllers due to mismatched MTU sizes.


C.

The client network is failing to communicate with the customer's domain controllers due to a missing network firewall port requirement.


D.

The FSVMs must first be manually added to a site mapping in Active Directory before they can be authorized to communicate with the logon servers.

• 2x physical SQL Clusters (Windows Server 2012R2 hosts)

After deploying a Nutanix AHV cluster, which two actions should the administrator take to meet the requirements? (Choose two.)

Options:

A.

Deploy Volumes to support the AIX and SQL workloads.


B.

Migrate the ESXI workloads to AHV using Move.


C.

Solution Documentation


B.

Upgrade Paths


C.

Hardware Compatibility Lists


D.

Compatibility and Interoperability Matrix


Expert Solution
Questions # 10:

A consultant is completing final network failover testing on a recently deployed AHV cluster.

The cluster consists of the following:

•Three nodes

•Two uplinks connected to two switches

•Supported SFPs

The consultant removed one SFP+ out of each node. Two of the nodes (Hostl I Host2) failed over to the backup NIC correctly without any interruption but have lost communication with the third node (Host 3) hypervisor/CVM. Inserting the original SFP+ back into the problematic node allowed the network to be connected and the two healthy nodes could communicate successfully again.

manage_ovs showjinterfaces output:

name mode link speed

cthO 10000 True 10000

ethl 10000 False None

eth2 10000 True 10000

eth3 10000 False None

Bridge: brO

Bond: brO-up

bond_mode: active-backup

interfaces: ethl ethO

lacp: off

lacp-fa I 1 back: false

lacp_speed: slow

What should the consultant validate first?

Options:

A.

Validate NIC card on node is seated properly.


B.

Validate that the correct interfaces are included in the bridge.


C.

Validate the customer has configured all their switch ports identically.
