Multiple choice

Which statement is true regarding routing protocols?

  1. RIP uses hop count and bandwidth as the metric for path selection and sendsupdates periodically.

  2. OSPF is a Cisco proprietary protocol that sends updates triggered by topology changes.

  3. EIGRP uses DUAL to calculate the shortest path and can be configured to do unequal cost load balancing.

  4. BGP is a path vector interior routing protocol.

C Correct answer
Explanation

EIGRP (Enhanced Interior Gateway Routing Protocol) uses the DUAL (Diffusing Update Algorithm) to calculate loop-free paths and supports unequal cost load balancing across multiple paths. Option A is wrong because RIP uses only hop count. Option B is wrong because OSPF is an open standard. Option D is wrong because BGP is exterior, not interior.
