1V0-21.20 Exam - Question 68


An administrator is migrating 100 virtual machines from one ESXi Host to another. The current 1GigE network cards are only migrating four virtual machines simultaneously.

Which action should the administrator take to increase that number to eight?

Show Answer
Correct Answer: C

To increase the number of virtual machines that can be migrated simultaneously from one ESXi host to another, the administrator should add a 10GigE network card to each ESXi host. A 1GigE network card typically supports the migration of four virtual machines at a time. Upgrading to a 10GigE network card would provide the additional bandwidth necessary to handle up to eight virtual machine migrations concurrently.

come on, show me where you got this answer from.. Port Mirroring really. I thought that when I paid for this subscription I would have quality, so far after question 50 I do not have any references and the answers are CRAP

Go study bum! You already have the questions, have the least decency to correct them.

Answer is C: A 1Gb NIC has a capacity of 4 units, so you can do 4 vMotion operations at a time from a given 1Gb NIC. A 10Gb NIC has a capacity of 8 units, so you can do 8 vMotion operations at a time from a given 10Gb NIC. https://blogs.vmware.com/performance/2021/02/vcenter-limits-for-tasks-running-at-the-same-time.html

This is correct, this is how the trainer in my Udemy Course has explained it, the exact same way.

C will be 40, so D(NIC Teaming)

Port mirroring is not a solution for increasing the number of virtual machines migrated simultaneously from one ESXi host to another. Port mirroring is a networking feature that allows traffic on one port (or ports) of a network switch to be forwarded to another port for analysis or monitoring purposes. A 10GigE network card provides significantly higher bandwidth compared to a 1GigE network card. With more bandwidth available, the ESXi hosts can handle more concurrent migrations without experiencing network congestion or slowdowns.
