Question No : 5
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?

A.Incorrect link speeds on the switch
B.The interface is incorrectly configured with Jumbo Frames
C.A misconfigured bond
D.A physical layer network problem

正解:
Explanation:
Ref:
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 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 see rx_crc_errors, not on all but one or two nodes.

Question No : 6

B.Increase the OPLOG
C.Increase the write cache
D.Use HDDs with higher RPM

Question No : 8
An administrator is supporting a business critical environment and deploys metro availability to achieve a zero data loss configuration. The two clusters are connected by a 1GbE connection. A new workload is going to be deployed to this cluster. This workload requires a sustained 150MB/S of write throughput and 20MB/s of read throughput.
Which change must be made to deploy the workload successfully on this cluster?

A.The bandwidth must be increased to support this workload.
B.The workload must be configured to read at greater than 12.5MB/
C.The replication frequency must be less than 60 minutes.
D.Zero data loss nearsync must be used to support this workload.
