Deploying Cisco Service Provider Core Network Technologies (SPCORE, legacy) — Question 15

A recent analysis of a service provider network infrastructure revealed the necessity to reinforce bandwidth control over all the 5 Mbps residential customer contracts. Which option is a viable solution to rate limit customers bandwidth both upstream and downstream?

Answer options

• A. class-based policing
• B. committed access rate on a per interface basis
• C. reserving 5 Mbps on Cisco MPLS TE tunnels that connect customers
• D. setting customer Ethernet links to 10 Mbps half-duplex

Correct answer: C

Explanation

The correct answer is C because reserving 5 Mbps on Cisco MPLS TE tunnels ensures that the bandwidth limit is enforced for both upstream and downstream traffic. Options A and B do not provide a solution for managing bandwidth across both directions effectively, and option D would unnecessarily increase the potential bandwidth available to customers, contradicting the need for rate limiting.
