Why do blind spots occur in a virtualized environment, where network-based security controls may not be able to monitor certain types of traffic?
Why do blind spots occur in a virtualized environment, where network-based security controls may not be able to monitor certain types of traffic?
Blind spots occur in a virtualized environment because virtual machines may communicate with each other over a virtual network on the same host rather than through a physical network. This makes it difficult for network-based security controls, which are designed to monitor traffic on physical networks, to detect or monitor traffic between virtual machines on the same host.
Please check the answer, i feel below should be the answer D. Virtual machines may communicate with each other over a virtual network all on the same host rather than a physical network between servers
your VMs are not always on the same host
That's not what the answer implicates, as it says VMs MAY (!) communicate over a virtual network all on the same host, not that they necessarily need to be. So many incorrectly marked answers in here, it's actually not worth the money.
Would choose D too
D should be the correct answer, the question is why do blind spots occur ... and one of the reason it could be that the vm's are on the same host
In my opinion is D
D. Virtual machines may communicate with each other over a virtual network all on the same host rather than a physical network between servers
Blind spots occur in a virtualized environment because virtual machines (VMs) can communicate with each other over a virtual network within the same host rather than sending traffic over a physical network between separate physical servers. This means that network-based security controls that are designed to monitor traffic on physical networks may not be able to detect or monitor traffic between virtual machines on the same host. Options A, B, and C are not accurate explanations for the occurrence of blind spots in virtualized environments.

VM's can communicate with each other outside the network so no traffic is analyzed
