Correct answer & explanation
✓
HA VPN with two Cloud VPN gateways and four tunnels
HA VPN offers a 99.99% SLA and supports up to 10 Gbps throughput. It requires two VPN gateways and four tunnels for redundancy. Dedicated Interconnect offers 10-100 Gbps but a 99.99% SLA only with two connections. Partner Interconnect provides up to 10 Gbps but the SLA depends on the partner. The question specifies up to 10 Gbps and a partner, but HA VPN is the only one with a built-in 99.99% SLA for a single connection. However, the 'supported partner' clue suggests Partner Interconnect, but its SLA is not 99.99% guaranteed by Google. The correct answer is HA VPN because it explicitly offers 99.99% SLA and can handle up to 10 Gbps.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Partner Interconnect with multiple VLAN attachments
Why it's wrong here
Partner Interconnect SLA depends on the partner; Google does not guarantee 99.99% for a single partner connection.
- ✗
Dedicated Interconnect with a single 10 Gbps connection
Why it's wrong here
A single Dedicated Interconnect connection has an SLA of 99.9%, not 99.99%. Two connections are needed for 99.99%.
- ✓
HA VPN with two Cloud VPN gateways and four tunnels
Why this is correct
HA VPN provides a 99.99% SLA and supports up to 10 Gbps throughput when configured with two gateways and four tunnels.
- ✗
Classic VPN with a single tunnel
Why it's wrong here
Classic VPN does not offer a 99.99% SLA and is limited to lower throughput.
