2V0-41.24 Question 137
Single answerAn organization is configuring high availability for their NSX-T Edge cluster to ensure network resilience. They need to decide between active-active and active-standby modes for their Tier-0 gateway. Which of the following statements about these modes is correct?
- A
Active-active mode balances traffic across all Edge nodes and is suitable for scenarios where stateful services such as NAT are not required.
- B
Active-standby mode provides better performance for north-south traffic by utilizing all Edge nodes simultaneously.
- C
Active-active mode requires dynamic routing protocols to achieve optimal traffic distribution.
- D
Active-standby mode is ideal for environments that need stateful services like NAT and ensures service continuity during failure.
Show answer and explanation
Correct answer: A
Explanation
Active-active and active-standby modes are two high availability configurations for NSX-T Edge clusters. Active-active mode is designed to balance network traffic across all available Edge nodes, making it suitable for stateless services. In contrast, active-standby mode is used for environments requiring stateful services like NAT, where one Edge node is designated as active and another as standby to ensure continuity during failures. Understanding these differences is essential to determine the appropriate configuration for specific use cases.
- A. Correct.
Active-active mode is designed to balance traffic across all Edge nodes, but it does not support stateful services such as NAT. This makes it suitable for scenarios without such requirements.
- B. Incorrect.
Active-standby mode does not utilize all Edge nodes simultaneously for traffic; instead, it designates one Edge node as active and the other as standby for failover purposes.
- C. Incorrect.
While active-active mode can benefit from dynamic routing protocols for traffic distribution, this is not a defining characteristic or primary requirement for this mode.
- D. Incorrect.
Active-standby mode supports stateful services like NAT and ensures service continuity during failure, but it does not provide the same level of traffic balancing as active-active mode.
