Question

Your company needs hybrid connectivity to a single Google Cloud region. The finance team approved a budget that allows only a single Partner Interconnect connection tier, but the operations team requires a documented 99.9% availability SLA for the VLAN attachment. During design review, an engineer proposes placing a single VLAN attachment on one edge availability domain. What must you change to actually qualify for the 99.9% SLA on Partner Interconnect?

Accepted Answer

Provision two VLAN attachments in the same metro but in two different edge availability domains, each with its own Cloud Router BGP session.

Answer

Provision four VLAN attachments spread across two metros and two regions, using global dynamic routing.

Answer

Keep the single VLAN attachment but enable MACsec encryption to raise the availability guarantee.

Answer

Keep the single VLAN attachment and add a Classic VPN tunnel as backup to reach 99.9%.
