Exam 200-301 topic 1 question 890 discussion

C makes the most sense, but how exactly would you do these advertisements? VTP mode transparent? Is there any other way?

By advertising a more specific route for the backup traffic via the secondary circuit, the engineer can direct this high-bandwidth traffic away from the primary circuit, helping to prevent saturation. This approach is inexpensive as it utilizes existing infrastructure rather than requiring new hardware or dedicated circuits, and it takes advantage of routing mechanisms to control traffic flow. Incorrect options: A and B: These organize local traffic but don't prevent WAN saturation. D: Effective but costly, requiring new circuits.

i think placing the servers in a dedicated vlan doesnt address the issue because you will still need a traffic path to reach that vlan/subnet

2 key points here are: "inexpensively update" and "avoid saturation of the primary circuit" so we need setup the backup at secondary circuit. Moreover, dedicated ... are expensive things.

The correct answer is B. Place the backup servers in a dedicated VLAN. Placing the backup servers in a dedicated VLAN allows for the segregation and control of the backup traffic within the data center. This solution helps prevent saturation of the primary circuit by dedicating a specific VLAN for the backup traffic and allowing bandwidth management, traffic isolation, and the implementation of Quality of Service (QoS) policies.

This is not CCNA 200-301

To inexpensively update the data center and avoid saturation of the primary circuit by traffic associated with the backups, the network engineer can implement the following solution: C. Advertise a more specific route for the backup traffic via the secondary circuit. By advertising a more specific route for the backup traffic via the secondary circuit, the engineer can ensure that the backup traffic is directed through the secondary circuit instead of overwhelming the primary circuit. This can be achieved by configuring the routing protocols or static routes to prioritize the secondary circuit for the backup traffic. This approach allows the engineer to leverage the existing infrastructure and circuits without the need for additional dedicated equipment or circuits, making it a cost-effective solution. It effectively separates the backup traffic from other data center traffic and ensures efficient utilization of the available network resources.

Answer C is correct since it is the most inexpensive option with it being a simple, IP route specification. Everything else is either more time consuming or requires more overhead costs.

I think that all the given answers could be correct. Can anyone explain?
