2V0-41.24 Question 338
Select 3You are tasked with creating a Tier-0 gateway in an NSX-T Data Center to connect your data center network to an external physical router. Your organization has the following requirements:
- The network must support ECMP (Equal-Cost Multi-Pathing) for high availability and load balancing.
- The Tier-0 gateway must establish BGP sessions with the external router for dynamic routing.
- The gateway must support north-south traffic routing.
Which steps must you perform when creating the Tier-0 gateway to meet these requirements?
- A
Enable the 'High Availability' mode for the Tier-0 gateway.
- B
Set the 'Failover Mode' to 'Active-Active' during the Tier-0 gateway configuration.
- C
Configure BGP on the Tier-0 gateway and establish a neighbor relationship with the external physical router.
- D
Add Tier-1 gateways as child gateways under the Tier-0 gateway.
- E
Attach one or more external interfaces to the Tier-0 gateway and assign IP addresses.
Show answer and explanation
Correct answers: B, C, E
Explanation
To meet the organization's requirements, the Tier-0 gateway must be configured to support ECMP, which requires 'Active-Active' failover mode. Additionally, BGP must be configured to establish dynamic routing with the external router, and external interfaces must be attached and assigned IP addresses to enable north-south traffic routing. The other options are either not required or irrelevant to the scenario's requirements.
- A. Incorrect.
Enabling 'High Availability' mode is not necessary in this scenario because ECMP is being used for high availability and load balancing. ECMP requires 'Active-Active' failover mode, not standard high-availability mode.
- B. Correct.
Setting the 'Failover Mode' to 'Active-Active' is required to enable ECMP on the Tier-0 gateway, as ECMP relies on multiple active paths for traffic distribution.
- C. Correct.
Configuring BGP on the Tier-0 gateway and establishing a neighbor relationship with the external router is necessary for dynamic routing, which is one of the organization’s requirements.
- D. Incorrect.
Adding Tier-1 gateways as child gateways under the Tier-0 gateway is not needed for this specific scenario, as the focus is on north-south traffic routing and connectivity to the external router.
- E. Correct.
Attaching external interfaces to the Tier-0 gateway and assigning IP addresses is essential for connecting the gateway to the physical external network and enabling north-south traffic.
