Sample Question:
Q: Which protocol uses DUAL algorithm for routing decisions?
A: EIGRP (Enhanced Interior 200-125 exam questions answers Gateway Routing Protocol) uses the DUAL algorithm for routing decisions.
Answer Explanation: EIGRP is a Cisco proprietary protocol that uses the DUAL (Diffusing Update Algorithm) to calculate the shortest and most efficient path for data transmission. It is known for being fast and efficient.
Tips:
Study the differences between distance-vector, link-state, and hybrid routing protocols.
Be familiar with static routing and when it is used.
Practice configuring OSPF and EIGRP on Cisco devices.
