What would be a valid reason to enable traffic shaping?
Answer : A
Explanation:
By limiting the bandwidth of a FTP server, you can enable traffic shaping.
A vSphere 5.x implementation contains two ESXi hosts, ESXi01and ESXi02. There is a virtual machine "VM21" connected to the Production port group on ESXi01.
ESXi01 has the following switch configuration.
vSwitch0, single uplink to 10.1.20.0/24
Production port group -
VMkernel port for vMotion -
VMKernel port for management -
vSwitch1, single uplink to 10.1.40.0/24
Engineering port group -
VMKernel port for NFS storage -
ESXi02 has the following switch configuration.
vSwitch0, single uplink to 10.1.20.0/24
Engineering port group -
VMkernel port for vMotion -
VMKernel port for management -
vSwitch1, single uplink to 10.1.40.0/24
Production port group -
VMKernel port for NFS storage -
Which two statements are true about this configuration? (Choose two.)
Answer : B,D
Explanation:
If VM21 is migrated to ESXi 02, then according to the information provided, it will not be available on the network. Likewise, broadcasts from production port group will not reach engineering port group.
Which network settings are only available with vSphere Distributed Switches?
