- Objective 8.2 – Perform Basic Troubleshooting for VMware FT and Third-Party Clusters
SMP is supported on FT protected machines?
Mastering VMware vSphere 4, page 494
VMware FT currently supports only those VMs with one vCPU. SMP and multiprocessor VMs are not supported.
Fault Tolerance supports thin provisioned disks?
Step 1: Turn on VMware Fault Tolerance for a virtual machine
1. Once your cluster is enabled with VMware HA, you can protect any virtual machine with VMware FT, given that the following prerequisites are met:
The ESX host must have an FT-enabled CPU. For details please refer to http://kb.vmware.com/kb/1008027. 2. Hosts must be running the same build of ESX.
3. Hosts must be connected via a dedicated FT logging NIC of at least 1 Gbps.
4. Virtual machine being protected must have a single vCPU.
5. Virtual machine’s virtual disk must be thick provisioned
The information shown in the exhibit must be configured to support which cluster
The dialog below shows the affect of enabling Vmware HA.
Which of the following occurs if VMware Fault Tolerance is enabled for a virtual machine in a DRS/HA cluster, but Host Monitoring is not enabled for VMware HA?
A.If the primary FT VM fails, the secondary FT VM does not take over
B.Memory reservations for the FT VM cannot be upheld and there might not be sufficient resources to restore redundancy if an HA event occurs
C.If the primary FT VM fails, a new secondary FT VM is not created and the VM is no longer redundant
D.Anti-affinity rules for the FT VM cannot be upheld and both the primary and secondary FT VM could reside on the same host
Thanks to Anti-affinity rules, VMware Fault Tolerant virtual machines are?
A.Never located within the same cluster
B.Sometimes located on the same host, but only in a powered off state
C.Never located on the same host
D.Sometimes located on the same host if an HA event occurs
While verifying host connectivity to datastores using Topology Maps, you see that one of the hosts in a DRS/HA Cluster has a red X. What does this indicate?
A.The host cannot access the selected datastore
B.The host cannot be contacted to update the Topology Map
C.The host is not compatible for VMotion migration
D.The host has failed as part of an HA event
