2V0-41.24 Question 128
Single answerA network administrator is configuring routing in a VMware NSX-T Data Center environment. The administrator needs to ensure high availability and dynamic path selection between two Tier-1 gateways connected to Tier-0. The environment also requires quick convergence in case of link failures and must support external connectivity to an enterprise WAN. Based on these requirements, which routing configuration should be used?
- A
Use static routing between Tier-1 gateways and Tier-0, and configure OSPF for external connectivity.
- B
Configure BGP between Tier-1 gateways and Tier-0, and use static routing for external connectivity.
- C
Implement OSPF between Tier-1 gateways and Tier-0, and configure BGP for external connectivity.
- D
Use static routing between Tier-1 gateways and Tier-0, and configure static routes for external connectivity.
Show answer and explanation
Correct answer: C
Explanation
To meet the requirements for dynamic path selection, quick convergence, and external connectivity, OSPF should be used between Tier-1 and Tier-0 gateways within the NSX-T environment. This allows for efficient internal routing. BGP is the preferred choice for external connectivity to the enterprise WAN, as it provides scalability, dynamic path selection, and support for failover.
- A. Incorrect.
Static routing between Tier-1 and Tier-0 does not provide dynamic path selection or quick convergence. While OSPF for external connectivity is possible, the lack of dynamic routing within the NSX environment does not meet the requirements.
- B. Incorrect.
BGP between Tier-1 and Tier-0 is not the best choice for dynamic path selection and quick convergence within the NSX environment. Additionally, using static routing for external connectivity does not allow for dynamic failover or scalability.
- C. Correct.
Using OSPF between Tier-1 and Tier-0 provides dynamic path selection and quick convergence within the NSX environment. Configuring BGP for external connectivity ensures dynamic routing to the enterprise WAN, which meets all the requirements.
- D. Incorrect.
Static routing in both scenarios does not provide dynamic path selection, quick convergence, or scalability for either internal or external connections.
