300-420 Question 303
Select 3An enterprise network is designed with multiple branch sites that use a centralized controller for policy and configuration management. The network administrator wants to implement periodic publication to distribute route updates to the branches efficiently. Which of the following considerations must be addressed to ensure proper implementation of periodic publication?
- A
Ensure that the publication interval aligns with the branch routers' processing capabilities.
- B
Configure a reliable transport protocol, such as TCP, for the periodic updates to ensure delivery.
- C
Enable synchronization of periodic updates with network devices' routing timers to avoid conflicts.
- D
Use multicast or anycast mechanisms to efficiently distribute periodic updates to multiple branches.
- E
Reduce the publication interval to the lowest possible value to minimize update delays.
Show answer and explanation
Correct answers: A, C, D
Explanation
Periodic publication involves distributing updates at regular intervals to ensure consistent and efficient dissemination of information across the network. Proper configuration requires considering processing capacity, synchronization with routing timers, and efficient distribution mechanisms like multicast or anycast. These considerations ensure network stability, scalability, and optimal performance. Reducing the interval excessively or relying on protocols like TCP, which are not typically used for this purpose, can lead to inefficiencies.
- A. Correct.
Periodic publication intervals must be configured to match the branch routers' processing capabilities to avoid overloading devices and ensure updates are processed correctly.
- B. Incorrect.
While TCP provides reliability, periodic publication often uses other mechanisms like multicast or UDP for efficiency. TCP is not typically required for this purpose.
- C. Correct.
Synchronization of periodic updates with routing timers helps avoid timing conflicts and ensures updates are processed in harmony with existing routing configurations.
- D. Correct.
Multicast or anycast mechanisms are optimal for distributing updates to multiple branches, reducing bandwidth consumption and ensuring scalability.
- E. Incorrect.
While shorter intervals may reduce update delays, overly frequent updates can cause unnecessary network overhead and degrade performance.
