QuestionQ18

Layer 2 VPNs

Which two types of frames can be configured on an Ethernet flow point?

Choose two
  • A of a specific VLAN
  • B with different type of service values
  • C with identical type of service value
  • D with different class of service values
  • E with no tags
Explanation

An Ethernet Flow Point can match frames associated with a specific VLAN and frames with no VLAN tags (untagged). Type of Service is an IP-layer field rather than an Ethernet EFP match criterion, and a CoS criterion is based on identical—not different—CoS values.
