Q1Implementing hybrid interconnectivityeasy

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?

ACombine Dedicated Interconnect with a Cloud VPN tunnel for failover
BUse Partner Interconnect instead of Dedicated Interconnect
Provision two VLAN attachments on two separate Cloud Routers in different zonesCorrect
DProvision a single VLAN attachment on one Cloud Router

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, providi…Read full explanation

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?

AAS path prepending is causing route flapping
Asymmetric routing is causing traffic to be dropped by stateful firewallsCorrect
CCloud Router is not configured for ECMP
DThe BGP MED attribute is misconfigured

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.…Read full explanation

Q3Implementing hybrid interconnectivityhard

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?

AConfigure multiple VLAN attachments on a single Cloud Router and rely on link aggregation
BDeploy Cloud VPN tunnels as backup and configure static routes with lower priority
CConfigure VPC Network Peering between all data centers and Google Cloud
Use a Cloud Router with BGP and establish multiple BGP sessions over each InterconnectCorrect

Option D is correct because 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 wit…Read full explanation
