Several VPN instances have been set up on an HP Comware switch. What should the
administrator do to ensure that no VPN instance uses up too many switch resources?
A.
Bind each instance to a specific port group or ASIC
B.
Set a maximum number of routes that each instance can have in its routing table.
C.
Apply a service policy to each instance to assign that instance a percentage of resources
D.
Set a CPU weight for each VPN instance to control how much of the CPU the instance
can use.

As per student guide below:
VPN instance routing table limits allow a network operator to restrict the number of
active routes allowed in a VPN instance.
It is recommended that VPN instance routing limits be configured on all customer
VPNs to ensure resource protection. If this is not done, a single VPN instance
could potentially consume all hardware resources.
As an example, if OSPF was configured within a customer VPN instance, the
OSPF process within the VPN instance may be learning hundreds or thousands of
routes from an external OSPF router. However, the same underlying hardware or
ASICs are being used for all OSPF processing in all VPN instances on that device.
A customer VPN instance may be able to consume a disproportionate amount of
resources, or in the worst case scenario, consume all resources on core devices.
So the correct answer is :
B. Set a maximum number of routes that each instance can have in its routing table.
