Q1Domain Verified
When designing a hybrid connectivity solution using Cloud VPN, what is the primary advantage of using BGP over static routing for managing routes between on-premises and Google Cloud networks, especially in large or dynamic environments?
BGP requires less bandwidth and processing power on the VPN gateway compared to static routes.
BGP is a proprietary protocol developed by Google Cloud, ensuring seamless integration and enhanced security.
BGP automatically advertises network prefixes and converges faster during network changes, reducing manual intervention and downtime.
BGP offers simpler configuration and lower overhead, making it ideal for small, static networks.
Q2Domain Verified
A multinational organization is migrating its critical applications to Google Cloud and requires highly available and low-latency connectivity between its global on-premises data centers and its Google Cloud VPCs. Which hybrid connectivity solution should be prioritized for its ability to offer dedicated, private, and consistent performance?
A combination of Cloud VPN and a third-party SD-WAN solution for advanced traffic management.
Cloud VPN with IPsec tunnels, configured for optimal latency using geographically dispersed VPN gateways.
Cloud Interconnect (Dedicated or Partner) to establish a direct, private connection to Google's network edge.
Public internet access via Cloud NAT, ensuring broad accessibility for all applications.
Q3Domain Verified
You are designing a VPC network in Google Cloud that will host sensitive microservices. To enforce strict ingress and egress control, you decide to implement a "deny-all" firewall rule followed by specific "allow" rules. When creating a custom egress firewall rule to allow outbound traffic only to a specific set of external IP addresses, what is the most effective method to manage these IP addresses for scalability and ease of maintenance?
Define an IP address group (or alias IP range) within the firewall rule configuration itself.
Hardcode the IP addresses directly into individual firewall rules.
Create multiple individual firewall rules, each allowing traffic to a single IP address.
Utilize a firewall tag applied to the target instances and then create a separate "allow" rule with the destination IP addresses.
