— Exhibit —
An ESXi host’s networking is configured as shown. The virtual machine named Fileserver01 is
unable to ping anything on an external network:
Which condition would explain this behavior?
A.
The vSwitch1 virtual switch does not have an attached vmnic adapter.
B.
The Fileserver01 virtual machine is not running.
C.
vSwitch0 is configured to reject MAC address spoofing.
D.
vmk0 is using a non-routable IP address.
Explanation:
can anyone throw some light on this question. Both Vswitches 0 and 1 are connected to same vmnic0. How is this possible ?? And fileserver01 is clearly powered on as shown in the exhibit…
I agree with Chandra,
fileserver01 is powered on. I’m sure the right answer is D.
But vmk0 and VM network can have different vlans … maybe mistake on a picture
I think this is an IQ question (as so many with VMware).
Answer D. does NOT answer the question, but what it is TRUE that any IP-address beginning with 172. (like 10. and 198.) are NON routable.
All other answers are FALSE.
Not completely true… Addresses beginning with 172.16 through 172.31 are non routable in the world. ALL OTHER 172.X.X.X addresses are routable.
A – not true
B – on picture is ON and how to ping from if is not ON !!!
C – the similar security option is “MAC Address Changes” but this is not the same
D – no – vmk0 – is a managment network not for VM OS no efect on rest part of network
any idea ???!!!
after study i said :
C – is ok
http://wahlnetwork.com/2013/04/23/rejecting-vmware-mac-address-changes/
Note on the screenshot that Fileserver01 shows disconnected. Anyway only C apply while MAC Address Changes is implemented.
The point is that all the other sites I’ve checked state that A is correct.
This question is so rediculous
Agree. To much C&P.
Best answer is None of the above 😉 So leave the question unanswered.
Answer is C
Agreeing with JanK above
(No the exact word, but spoofing, can be equal to “MAC Address Changes”)
“MAC Address Changes” is being set to Reject by default in a distributed switch
But set to Accept by default with a standard switch.
Answer is C
Guys…. The real explanation for this is that the answer is correct and it is the image which is wrong.
On the test, the image shows the machine as truly powered off. Whoever put together this vce is lazy.
Yep, I agree with Raynholm. Picture is wrong as this is the same picture just taken from another question.
Just did the exam (passed). I got this question, and the machine was powered on there too! The answer is 100% D, non routable IP address.
imho it’s D. 172.16.x.y/16 is routable and the private class B range is 172.16.x.y/16 – 172.31.x.y/16 however it states “EXTERNAL” network, so not directly routable outside of private range however this would work fine with NAT router.
the picture shows it as not connected but that’s just guff as it’s not an answer, and vmnic in use twice. sloppy screen shotting from the test guys – £162 for a voucher? mmmm….
actually, probably sloppy screenshotting from braindumpers! that’s why using BDs without IQ and actual knowledge = deserved fail;)
I think there is a mistake in the picture as the vm fileserver01 should not be powered on as shown, If it is still then the options are not correctly framed..
First of all vmnic0 on two switches:: incorrect,
VM shows no connection to the virtual switch, which is incorrect again, even if mac address spoofing is rejected, a connection should have been there,
for heavens sake it has nothing to do with the ip addresses..
a virtual machine does not get ip address from a management network..
conclusion:image is wrong.
Exactly – image is faulty but, similar to Q119, may be on the exam (something for VMware Education to fix)…
Having said that, however, the only plausible answer (under circumstances) is ‘C’ – vSwitch is configured to reject MAC address spoofing.
Another fucking shit thrown at our face!
B – is correct. The picture is wrong. When the machine is powered ON you can see it is connected to uplinks (similar to vcenter appliance). I tested in Lab.
Perhaps the question should be “An ESXi host’s networking is configured as shown. The virtual machine named Fileserver02 is unable to ping anything on an external network:”
“VMware vCenter Appliance” has GREEN DOT connection on the switch
“FileServer01”, “FileServer02” NO GREEN DOT connection on the switch
Maybe it means: B.The Fileserver01 virtual machine is not (completely) running.
Always blame the connection failure to your fileserver administrator first (check Q119)
Vmware well done !!
解答はBになっているが、皆さん納得されずコメントが荒れています。
「この問題の図が間違っている。本当の試験では電源オフになっているはず」という意見がある一方、

「Just did the exam (passed). I got this question, and the machine was powered on there too! 」
（ホントの試験でも同じように電源オンの図だった）と書いています。
結局、どれが答えかわかりません
Image has to be wrong BUT:
IF B.The Fileserver01 virtual machine is not running. – It Could not PING ANYTHING – So WRONG
IF C.vSwitch0 is configured to reject MAC address spoofing – How can you draw that conclusion – You Can’t – So WRONG
IF D. vmk0 is using a non-routable IP address. – The 172.16 address is for the MGMT – NOT RELEVANT – So WRONG
IF A. The vSwitch1 virtual switch does not have an attached vmnic adapter. – VM’s could ping each other BUT NOT External – RIGHT ANSWER
Answer = A
The screenshot linked to this question is wrong. There should have been a screenshot that showed a powered off VM. This screenshot is from another question (120 and also there wrong). vmnic0 is connected to two vSwitches, which is not allowed.
