2V0-41.24 Question 252
Select 2An organization has deployed VMware NSX Federation across multiple sites to enable centralized management and control. They want to extend a VLAN segment across these sites while ensuring Layer 2 connectivity is maintained. What must be configured to achieve this?
- A
Configure a Tier-0 gateway in Active-Active mode at each site.
- B
Enable the stretched VLAN segment across the participating NSX Local Managers.
- C
Establish Layer 2 VPN (L2VPN) tunnels between the sites.
- D
Deploy NSX Global Manager to manage the VLAN segment across sites.
- E
Ensure that the participating sites are part of the same NSX Federation domain.
Show answer and explanation
Correct answers: B, E
Explanation
To extend a VLAN segment across multiple sites in an NSX Federation setup, the VLAN segment must be stretched across the participating NSX Local Managers. Additionally, the sites involved must be part of the same NSX Federation domain to ensure centralized management and Layer 2 connectivity. These steps leverage NSX Federation's native capabilities for Layer 2 extension without requiring external tools like L2VPN.
- A. Incorrect.
Configuring a Tier-0 gateway in Active-Active mode is not required for stretching a VLAN segment across sites. Tier-0 gateways are primarily used for North-South traffic flow and routing, not for Layer 2 extension.
- B. Correct.
Enabling the stretched VLAN segment across the participating NSX Local Managers is necessary to ensure Layer 2 connectivity across sites. This is a fundamental capability of NSX Federation.
- C. Incorrect.
Establishing Layer 2 VPN (L2VPN) tunnels is not required in NSX Federation. NSX Federation provides native capabilities for Layer 2 extension without the need for L2VPN.
- D. Incorrect.
While NSX Global Manager is a key component of NSX Federation, deploying it alone does not extend a VLAN segment. It is used for centralized management and orchestration.
- E. Correct.
Ensuring that the participating sites are part of the same NSX Federation domain is required, as NSX Federation enables seamless coordination of networking and security policies, including Layer 2 extension, within a single federation domain.
