300-415 Question 62
Single answerAn organization is deploying Cisco SD-WAN and plans to extend connectivity to a colocation facility to provide reliable access to cloud applications. The organization wants to ensure that its branch sites can communicate with the colocation site over secure, optimized links. Which design consideration is MOST critical when deploying SD-WAN in a colocation environment?
- A
The colocation facility must support MPLS circuits exclusively for SD-WAN traffic.
- B
The colocation facility must provide redundant connectivity to the SD-WAN fabric.
- C
The colocation facility must support only direct internet access (DIA) for SD-WAN communication.
- D
The colocation site must host SD-WAN controllers in its local environment.
Show answer and explanation
Correct answer: B
Explanation
When deploying SD-WAN in a colocation environment, ensuring redundant connectivity to the SD-WAN fabric is essential for high availability and reliable communication. Redundant links at the colocation site prevent service interruptions and provide consistent access to cloud applications and branch sites. Other factors like transport type (MPLS, DIA) and controller hosting location are secondary to the need for redundancy in this scenario.
- A. Incorrect.
MPLS circuits are not exclusively required for SD-WAN traffic. SD-WAN supports multiple transport options such as MPLS, broadband, and LTE.
- B. Correct.
Redundant connectivity to the SD-WAN fabric is critical to ensure high availability and reliability, especially when the colocation site serves as a hub for branches and cloud applications.
- C. Incorrect.
Direct internet access (DIA) is an option for SD-WAN communication but is not mandatory. SD-WAN supports multiple transport types, and redundancy is more critical in this scenario.
- D. Incorrect.
SD-WAN controllers are typically hosted in data centers or the cloud, not necessarily in a colocation site. The controllers do not need to reside at the colocation facility for SD-WAN communication to function effectively.
