Cloud Digital Leader Google Cloud Products and Services Practice Question
A company wants to implement a hybrid cloud architecture connecting their on-premises data center to Google Cloud. They need high bandwidth (10 Gbps), low latency, and a service-level agreement (SLA). Which TWO services can provide dedicated connectivity? (Choose two.)
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
✓
Cloud Interconnect (Partner)
Cloud Interconnect (dedicated or partner) provides high-bandwidth, low-latency connections with SLAs. HA VPN is a VPN alternative but does not offer dedicated bandwidth or SLA for throughput. So the two correct are Cloud Interconnect (Dedicated Interconnect) and Cloud Interconnect (Partner Interconnect). However, the question asks for services that provide dedicated connectivity with SLA. Both Dedicated Interconnect and Partner Interconnect offer SLAs. HA VPN does not. So I'll include both types of Interconnect, but since they are the same service, I need to differentiate. Let's list options: A. Cloud VPN, B. HA VPN, C. Cloud Interconnect (Dedicated), D. Cloud Interconnect (Partner), E. Cloud CDN. So C and D are correct.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
HA VPN
Why it's wrong here
HA VPN is an IPsec VPN tunnel managed by Google, offering 99.99% availability via two tunnels, but it traverses the public internet. Because it uses the public internet, throughput can vary and Google does not provide a dedicated bandwidth or latency SLA. So while it's resilient, it's not suitable when guaranteed bandwidth is required.
- ✗
Cloud CDN
Why it's wrong here
Cloud CDN is a global content delivery network that caches static and dynamic content at Google's edge points of presence. It does not provide a private, dedicated connection between on-premises and Google VPC; it's optimized for delivering content to end users, not for hybrid cloud networking. It cannot carry arbitrary private traffic or provide interconnectivity SLAs.
- ✓
Cloud Interconnect (Partner)
Why this is correct
Partner Interconnect establishes a connection between your on-premises network and Google's network via a supported third-party service provider, such as a colocation or network provider. It offers a service-level agreement (up to 99.99%) and can be provisioned at capacities from 50 Mbps to 10 Gbps depending on the partner, making it suitable for hybrid workloads. Unlike VPN, it does not traverse the public internet, providing more reliable, lower-latency connectivity.
- ✓
Cloud Interconnect (Dedicated)
Why this is correct
Dedicated Interconnect provides a direct physical connection between your on-premises network and Google's network in a Google colocation facility. It supports 10 Gbps or 100 Gbps connections and comes with an SLA of up to 99.99% availability. This option is ideal for high-throughput, latency-sensitive workloads, but it requires you to arrange physical infrastructure, such as a cross-connect and a router, in the colocation facility.
- ✗
Cloud VPN
Why it's wrong here
Cloud VPN is a basic IPsec VPN tunnel that operates over the public internet, so Google provides no SLA for bandwidth or availability. It is often used for lightweight, test, or temporary connections and is easy to set up. However, it cannot guarantee consistent throughput and is not designed for production hybrid workloads that require dedicated capacity or a contractual service-level agreement.
