Which of the following statements best describe network traffic shaping (Choose Two)?
A.
Network traffic shaping can limit inbound peak bandwidth
B.
Network traffic shaping can limit outbound peak bandwidth
C.
Network traffic shaping can limit inbound average bandwidth
D.
Network traffic shaping can limit outbound average bandwidth
Explanation:
vSphere HelpESX/ESXi allows you to shape outbound traffic on virtual switches. The traffic shaper
restricts the network bandwidth available to any port, but may also be configured to
temporarily allow “bursts” of traffic to flow through a port at higher speeds.
A traffic shaping policy is defined by three characteristics: average bandwidth, peak
bandwidth, and burst size.
Average Bandwidth – Establishes the number of bits per second to allow across a port,
averaged over time-the allowed average load.
Burst Size – The maximum number of bytes to allow in a burst. If this parameter is set, a
port may gain a burst bonus when it doesn’t use all its allocated bandwidth. Whenever the
port needs more bandwidth than specified by Average Bandwidth, it may be allowed to
temporarily transmit data at a higher speed if a burst bonus is available. This parameter
tops the number of bytes that may be accumulated in the burst bonus and thus transferred
at a higher speed.
Peak Bandwidth – The maximum number of bits per second to allow across a port when it
is sending a burst of traffic. This tops the bandwidth used by a port whenever it is using
its burst bonus. This parameter can never be smaller than the average bandwidth.
