CCNA: Cisco Certified Network Associate — Question 725

A network engineer is upgrading a small data center to host several new applications, including server backups that are expected to account for up to 90% of the bandwidth during peak times. The data center connects to the MPLS network provider via a primary circuit and a secondary circuit. How does the engineer inexpensively update the data center to avoid saturation of the primary circuit by traffic associated with the backups?

Answer options

• A. Assign traffic from the backup servers to a dedicated switch.
• B. Place the backup servers in a dedicated VLAN.
• C. Advertise a more specific route for the backup traffic via the secondary circuit.
• D. Configure a dedicated circuit for the backup traffic.

Correct answer: C

Explanation

The correct answer is C because advertising a more specific route for the backup traffic via the secondary circuit effectively directs that traffic away from the primary circuit, thus preventing saturation. Options A and B do not address the issue of bandwidth management across circuits, while option D involves higher costs by requiring a new circuit rather than utilizing the existing ones.
