Answer(s): A
An administrator needs to create and start five new VMs for a Data Analytics Project (OLAP). The VM Profile is as follows:· vCPU:4· vRAM: 64 GB· vDisk: 1.5 TBEach of the four nodes of the Nutanix cluster has the following:· 24 vCPU. 20% overall usage· 192 GB RAM, 60% overall usage· 2xl920GBSSD· 4x 2 TB HDDAt cluster level, there is a single RF2 container that is 30% utilized and has an extent store capacity of 13.5 TB.Which component requires administrator attention?
An administrator receives an alert in Prism indicating that interface eth2, on an AHV host is receiving many CRC errors. Aftertogging into the problematic host, the following command is run to show the indicated output:What is causing this issue?
Answer(s): B
rx_crc_errors are 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 10Gig 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 see rx_crc_errors, not on all but one or two nodes.
Refer to the exhibit.After performing ESXi to AHV conversion on a cluster, the alerts shown in the exhibit display on Prism. What should the administrator do to resolve this issue efficiently?
