Start Implementing Hybrid Interconnectivity PracticeA company is planning to migrate workloads to Google Cloud and needs to establish hybrid connectivity with high bandwidth (10 Gbps) and low latency. They also require the ability to scale bandwidth up to 80 Gbps in the future. Which TWO options should they consider?
Explanation: Dedicated Interconnect provides direct, private physical connections between your on-premises network and Google Cloud, supporting 10 Gbps or 100 Gbps per circuit. This meets the requirement for high bandwidth (10 Gbps) and low latency, and allows scaling up to 80 Gbps by adding multiple 10 Gbps circuits or using a 100 Gbps circuit. Partner Interconnect also provides private connectivity, but through a supported service provider, with options ranging from 50 Mbps to 10 Gbps per connection. Both Dedicated and Partner Interconnect can be used to achieve the required bandwidth and latency, and both can scale (Partner Interconnect by aggregating multiple connections). The other options (CDN Interconnect, Direct Peering, Cloud VPN) do not provide the guaranteed bandwidth, low latency, and scalability required.
You are configuring a Cloud Router for a Dedicated Interconnect VLAN attachment. The on-premises BGP AS number is 65001. You want to ensure that traffic from Google Cloud to on-premises prefers the primary attachment over the backup. Which BGP attribute should you configure on the primary Cloud Router to achieve this?
Explanation: To influence traffic from Google Cloud to on-premises (outbound from GCP), you need to affect the path selection on the Cloud Router for received routes. Local preference is a well-known BGP attribute used to prefer one path over another when multiple paths are received to the same destination. By setting a higher local preference on the primary Cloud Router for routes received from the primary attachment, the Cloud Router will prefer that path for outbound traffic. MED influences inbound traffic to the advertiser (on-prem to GCP), not outbound from GCP.
A company is deploying a Dedicated Interconnect with a 10 Gbps circuit to Google Cloud. They need to ensure high availability. Which configuration is required by Google Cloud to meet the high availability SLA?
Explanation: To meet the high availability SLA for Dedicated Interconnect, Google Cloud requires at least two VLAN attachments, each on a separate Cloud Router in different zones. This ensures that if one zone or Cloud Router fails, traffic can still flow through the other attachment, providing redundancy. A single VLAN attachment or a single Cloud Router does not meet the 99.99% availability SLA because it creates a single point of failure.
A company has a Hybrid Connectivity setup using Cloud VPN with dynamic routing (BGP). They notice that traffic from their on-premises network to Google Cloud is intermittently dropping. The on-premises BGP speaker is sending routes with a higher local preference (200) than the Google Cloud router (default 100). What is the most likely cause of the intermittent drops?
Explanation: The on-premises BGP speaker is sending routes with a higher local preference (200) than the default on Cloud Router (100). This makes the on-premises route preferred for return traffic from Google Cloud, but the forward traffic from on-premises may still use the Cloud VPN tunnel. This asymmetry causes stateful firewalls (e.g., on-premises firewall or Google Cloud firewall) to drop packets that do not match an existing session, leading to intermittent drops.
A multinational corporation is connecting five on-premises data centers to Google Cloud using Cloud Interconnect. Each data center has a dedicated 10 Gbps connection. They want to ensure that if one Interconnect fails, traffic is automatically redistributed across the remaining connections without manual intervention. Which solution meets this requirement?
Explanation: Cloud Router with BGP enables dynamic routing, allowing multiple BGP sessions over each Cloud Interconnect. When one interconnect fails, BGP withdraws the affected routes, and traffic is automatically redistributed across the remaining BGP sessions without manual intervention. This meets the requirement for automatic failover and load balancing across the five 10 Gbps connections.
