VMware SD-WAN by VeloCloud Specialist — Question 12

A customer is using VMware hosted SD-WAN services. The primary gateway has gone down and come up again.
Which statement is correct?

Answer options

• A. During the time when the primary VCG was down, Cloud (internet) traffic failed over to the secondary VCG.
• B. All VPN (site-to-site) traffic uses the primary VCG as primary data path.
• C. All Cloud (internet) traffic uses the primary VCG as primary data path.
• D. Once the primary VCG is back up, existing flows continue to go direct, and any new flow would travel via the primary VCG.

Correct answer: A

Explanation

The correct answer is A because during the downtime of the primary VCG, traffic is automatically directed to the secondary VCG to ensure continuity. Options B and C are incorrect as they suggest that all traffic relies solely on the primary VCG, which is not the case during its downtime. Option D is also incorrect as it implies that existing flows would switch to the primary VCG when it comes back up, which is not how the failover mechanism works.
