Traffic Shaping can be configured on the following vSphere elements
(Choose Two)?
A.
On a vNetwork Distributed Switch dvPort or the entire dvPort Group for outbound
traffic only
B.
On a vNetwork Standard Switch port group or the entire vSwitch for outbound traffic
only
C.
On a vNetwork Standard Switch port group or the entire vSwitch for inbound traffic
only
D.
On a vNetwork Distributed Switch dvPort or the entire dvPort Group for inbound and
outbound traffic
Explanation:
Bi-directional traffic shaping – vDS expands upon the egress only traffic shaping feature
of Standard Switches with bi-directional traffic shaping capabilities. Egress (from VM to
network) and now ingress (from network into VM) traffic shaping policies can now be
applied on DV Port Group Definitions.
Comparing vNetwork Standard Switch with vNetwork Distributed Switch
These features are available with both types of virtual switches:
•Can forward L2 frames
•Can segment traffic into VLANs
•Can use and understand 802.1q VLAN encapsulation
•Can have more than one uplink (NIC Teaming)
•Can have traffic shaping for the outbound (TX) traffic
These features are available only with Distributed Switch:
•Can shape inbound (RX) traffic
•Has a central unified management interface through vCenter
•Supports Private VLANs (PVLANs)
•Provides potential customisation of Data and Control Planes
vSphere 5.0 provides these improvements to Distributed Switch functionality:
•Increased visibility of inter-virtual-machine traffic through Netflow
•Improved monitoring through port mirroring (dvMirror)
•Support for LLDP (Link Layer Discovery Protocol), a vendor-neutral protocol.
