As part of last-ditch effort to cram my brain with all things vSphere-related prior to my VCP5 exam, I ran into an online test available at Pass4Test.com<\/a>. Wow – what a disaster!<\/p>\n

<\/p>\n

This test is for vCloud but has a couple vSphere questions in it. Here is a sample question:<\/p>\n

NO.5 On which two vSphere elements can traffic shaping be configured? (Choose two.)\nA. On a vSphere Distributed Switch dvPort for inbound and\/or outbound traffic\nB. On a vSphere Distributed Switch for inbound and\/or outbound traffic\nC. On a vSphere Standard Switch port group or the entire vSwitch for inbound traffic\nD. On a vSphere Standard Switch port group or the entire vSwitch for inbound and outbound traffic\nAnswer: A,B<\/pre>\n
Now…there is just one teensy little problem. They are wrong. Flat out, irretrievably, fail-the-test-now wrong. Read on for the Truth…<\/p>\n
The problem is this: Of the possible answers – only “A” *could* be correct. Both\u00c2\u00a0C & D are wrong as they reference standard switches and inbound (ingress) traffic – standard switches do not support traffic shaping on inbound traffic. But – “B” is wrong, too. Why? Because you do not set traffic shaping on the distributed switch. You can set it on the *portgroup* for the distributed switch. Or, you can set it on the *port* within the distributed switch. But it is wrong to say you set traffic shaping on a distributed switch itself.<\/p>\n
Traffic shaping is an interesting topic. You can shape traffic for Standard Switch or for Distributed Switch *portgroups* or *ports* (except for uplinks). But you cannot set traffic shaping for the “distributed switch” itself.<\/p>\n
Standard Switch<\/h2>\n
First, get to the selection by going to Host -> Configuration -> Networking -> vSphere Standard Switch and then “Properties” for the standard switch.<\/p>\n
\"vsphere_std_switch_properties\"<\/a><\/p>\n
Traffic Shaping can be set for the following:<\/p>\n
