CompTIA Network+ (N10-008) — Question 204

Which of the following will reduce routing table lookups by performing packet forwarding decisions independently of the network layer header?

Answer options

• A. MPLS
• B. mGRE
• C. EIGRP
• D. VRRP

Correct answer: A

Explanation

MPLS (Multiprotocol Label Switching) enhances packet forwarding efficiency by using labels to make forwarding decisions, which minimizes the need for routing table lookups. The other options, mGRE, EIGRP, and VRRP, do not provide the same level of optimization for packet forwarding as MPLS does.
