2V0-41.24 Question 98
Single answerAn organization is deploying VMware NSX in its data center to improve network efficiency and security. The network administrator needs to implement a routing architecture that supports both north-south and east-west traffic while maintaining tenant isolation. They decide to use NSX two-tier routing. Which statement accurately describes the purpose and components of this routing architecture?
- A
NSX two-tier routing consists of a distributed router (DR) for east-west traffic and a centralized service router (SR) for north-south traffic.
- B
NSX two-tier routing eliminates the need for tenant-specific routing and uses a single-tier router for all traffic.
- C
NSX two-tier routing is designed to support only east-west traffic in virtualized environments.
- D
NSX two-tier routing requires deploying multiple distributed routers (DRs) for each tenant to enable east-west traffic.
Show answer and explanation
Correct answer: A
Explanation
NSX two-tier routing is a logical routing architecture that consists of the distributed router (DR) and the centralized service router (SR). The DR handles traffic within the data center (east-west traffic) by distributing routing functionality to the hypervisors, minimizing latency and improving performance. The SR handles traffic entering and leaving the data center (north-south traffic) and provides services such as NAT and firewall capabilities. This architecture ensures efficient routing and supports multi-tenancy by logically isolating tenant routing environments.
- A. Correct.
Correct: NSX two-tier routing uses a distributed router (DR) to handle east-west traffic within the data center and a centralized service router (SR) to handle north-south traffic, ensuring efficient routing and tenant isolation.
- B. Incorrect.
Incorrect: NSX two-tier routing does not eliminate tenant-specific routing; it provides a logical separation of routing functions to support both east-west and north-south traffic.
- C. Incorrect.
Incorrect: NSX two-tier routing is designed to handle both east-west traffic within the data center and north-south traffic that leaves or enters the data center.
- D. Incorrect.
Incorrect: Multiple distributed routers (DRs) are not required per tenant; a single DR can manage east-west traffic for multiple tenants, and the architecture leverages logical separation for tenant isolation.
