You have deployed a two-tiered application using four virtual machines:
Two virtual machines are web application servers
Two virtual machines providing a clustered database service
What feature can you configure to provide the most accurate account for only the traffic between
the web servers and the clustered database?
A.
On the vSphere Distributed Switch, configure the use of a port mirroring session using the
Encapsulated Remote Mirroring (L3) Source session type.
B.
On the vSphere Distributed Switch, configure the use of a port mirroring session using the
Remote Mirroring Destination session type.
C.
On the vSphere Distributed Switch, configure the use of an Isolated Private VLAN for the ports
of the four virtual machines.
D.
On the vSphere Distributed Switch, configure Netflow for the distributed virtual port group and
enable Process internal flows only for the distributed switch.
C
its not clear question
Do not describe vms are on same host or on different VLANs , on same or different vxlan logical switch ?
Answer “A” could be correct, you can choose the web VMs ports as source and the cluster DB ports as destination and the result of those could be sent to an external host for analysis.
Answer “B” could be correct is the web servers are on a unique VLAN.
Answer “C” in incorrect.
Answer “D” could be correct only if all VMs belongs to the same VLAN, AND web servers never communicate each other.
The option ‘process internal flows’ when configuring a distributed switch for Netflow offers to monitor/ sample traffic ONLY on virtual workloads.
Secondly, the Netflow utility can also be applied to ‘individual virtual ports’ as well as ‘whole port groups’.
So yes, this makes option D the correct answer
