An administrator configure Active Directory (AD) authentication for their Nutanix environment. When login in using an AD user account, the login process takes more than one minute to complete. No delay occurs when logging a local account.
What should the administrator confirm to resolve this issue?
An administrator receives an alert in Prism indicating that interface eth2, on an AHV host is receiving many CRC errors. After togging into the problematic host, the following command is run to show the indicated output:
What is causing this issue?
Ref:
rx_crc_errorsare caused either by faults in layer 1 (in the past, we have seen failed twinax cables and incorrect types of fibre being used), or issues with jumbo frames on the network. In an environment with 10 Gig switches that use cut-through forwarding (Cisco Nexus, Arista, Cisco devices using IOS default to Store and Forward switching), any packets that come into the switch will get forwarded out the destination interface once the switch has read the destination MAC address. If that packet has an MTU over what is configured on the interface, it will cut off the packet at the designated MTU, causing the server to receive a malformed packet, which will throw a CRC error.
If you have a layer 1 issue, you will seerx_crc_errors,not on all but one or two nodes.
An organizations Nutanix Cluster is based on VMware vSphere. The cluster is configured to download software updates automatically. The administration needs to verify and eventually upgrade VMware hypervisor via Prism Ul.
After logging in to Prism, the administrator receives the message shown:
No available versions for upgrade
What is causing the current state?
Refer to the exhibit.
A Microsoft SQL 2016 deployment is shown in the exhibit. The administrator receives user reports that database queries take too long to return.
Which optimization should be made to this configuration to improve performance?
A customer has the following requirement for a Nutanix cluster:
Must support high-performance Nutanix Volumes iSCSI workloads
Must utilize AHV nodes
Must use 10 GbE interface
How should the customer optimize networking?
