Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
An organization is using Cloud Interconnect to connect their on-premises network to Google Cloud. They need to ensure 99.99% availability for their connection. Which configuration meets this requirement?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Two Dedicated Interconnect connections from different edge locations
To achieve 99.99% availability with Cloud Interconnect, you need two Dedicated Interconnect connections from different edge locations. This provides redundancy and meets the SLA requirement. A single connection (Dedicated or Partner) does not meet the 99.99% SLA. HA VPN is not a Cloud Interconnect solution; it's a separate VPN service that can also provide 99.99% SLA but is not Cloud Interconnect. Since the organization is using Cloud Interconnect, the correct configuration is two Dedicated Interconnect connections from different edge locations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A single Partner Interconnect connection at 1Gbps
Why it's wrong here
A single Partner Interconnect connection lacks redundancy and does not meet the 99.99% SLA requirement.
- ✓
Two Dedicated Interconnect connections from different edge locations
Why this is correct
Two Dedicated Interconnect connections from different edge locations provide the necessary redundancy to meet the 99.99% SLA. This is a supported Cloud Interconnect configuration.
- ✗
A single Dedicated Interconnect connection at 10Gbps
Why it's wrong here
A single Dedicated Interconnect connection, regardless of bandwidth, lacks redundancy and does not meet the 99.99% SLA.
- ✗
High Availability VPN (HA VPN) with two gateways and four tunnels
Why it's wrong here
HA VPN with two gateways and four tunnels provides 99.99% SLA, but it is not Cloud Interconnect. The question specifies using Cloud Interconnect, so this option is not applicable.
