2V0-41.24 Question 246
Single answerAn organization has implemented NSX Federation to connect multiple data center sites. They want to enable seamless network connectivity between virtual machines across these sites while maintaining consistent network policies. Which concept of stretched networking in Federation allows this functionality?
- A
Global Logical Switch (GLS)
- B
Tier-1 Gateway Synchronization
- C
Inter-Site L3 VPN
- D
Universal Logical Switch (ULS)
Show answer and explanation
Correct answer: A
Explanation
The Global Logical Switch (GLS) is the foundational concept in NSX Federation that enables stretched Layer 2 networking across multiple sites. It provides seamless connectivity for workloads across data centers while ensuring consistent network policies and configurations. Other options, such as Tier-1 Gateway Synchronization and Inter-Site L3 VPN, serve different purposes and do not directly facilitate stretched Layer 2 networking.
- A. Correct.
Global Logical Switch (GLS) is a key component of NSX Federation that enables the creation of a single logical network across multiple sites. This allows virtual machines to communicate seamlessly with consistent policies across different physical locations.
- B. Incorrect.
Tier-1 Gateway Synchronization is used to synchronize routing and gateway configurations across sites but does not directly enable stretched Layer 2 networking.
- C. Incorrect.
Inter-Site L3 VPN is used for site-to-site Layer 3 communication but does not provide stretched Layer 2 network connectivity.
- D. Incorrect.
Universal Logical Switch (ULS) was used in earlier versions of NSX but has been replaced by Global Logical Switch (GLS) in NSX Federation for stretched networking functionality.
