VCP-VCF Administrator 2024 Question 51
Select 3You are configuring BGP (Border Gateway Protocol) on an NSX Edge Cluster in a VMware Cloud Foundation environment. The goal is to enable communication between multiple external networks and your software-defined data center (SDDC). Which of the following are the roles of BGP in this scenario?
- A
Facilitating dynamic route propagation between the NSX Edge and external routers
- B
Providing Layer 2 connectivity across different sites
- C
Ensuring high availability of routed traffic through path selection
- D
Advertising routes learned from internal NSX segments to external networks
- E
Automatically creating firewall rules for all propagated routes
Show answer and explanation
Correct answers: A, C, D
Explanation
In an NSX Edge Cluster within VMware Cloud Foundation, BGP plays a critical role in enabling dynamic route propagation and path optimization between internal and external networks. It ensures scalability, high availability, and seamless communication by dynamically sharing routing information and selecting the most efficient paths. However, BGP does not provide Layer 2 connectivity or manage firewall rules, as these are outside its scope of functionality.
- A. Correct.
BGP is used to dynamically propagate routes between the NSX Edge and external routers in a scalable manner, ensuring the network topology can adapt to changes without manual intervention.
- B. Incorrect.
BGP operates at the Layer 3 (network) level, not Layer 2. It cannot provide Layer 2 connectivity across different sites.
- C. Correct.
BGP ensures high availability of routed traffic by selecting the best path based on attributes like AS path, weight, and MED.
- D. Correct.
BGP can advertise routes learned from internal NSX segments to external networks, enabling seamless communication between the internal and external environments.
- E. Incorrect.
BGP does not automatically create firewall rules. Firewall rules must be manually configured or automated through other NSX mechanisms.
