B) Dedicated Interconnect

C) Partner Interconnect

D) Carrier Peering

E) Direct Peering

F) Cloud NAT

Correct Answer: B

Explanation:

B is correct because Dedicated Interconnect provides a direct, physical connection between your on-premises network and Google's network, ensuring low latency and bypassing the public internet,

C is incorrect because Partner Interconnect uses a third-party service provider, which is suitable if you cannot meet Dedicated Interconnect requirements, but Dedicated is the primary choice for direct, lowest-latency private connections,

D is incorrect because Carrier Peering connects your infrastructure to Google Workspace and external APIs, not directly to your VPC resources privately,

E is incorrect because Direct Peering also connects to Google edge points for public Google services, not dedicated private VPC access,

F is incorrect because Cloud NAT is used for translating internal IP addresses to public IPs for outbound internet access, not for hybrid connectivity,

Question 2: You are designing a network security model for a multi-tiered application in Google Cloud, You need to enforce strict access controls between the web tier and the database tier using identity-aware mechanisms, Which approach aligns best with zero-trust networking principles in Google Cloud,

B) Relying solely on legacy network tags

C) Using Identity-Aware Proxy (IAP) combined with strict VPC firewall rules based on service accounts

D) Deploying a Cloud NAT gateway

E) Configuring Cloud DNS private zones

F) Setting up a public load balancer

Correct Answer: C

Explanation:

B is incorrect because legacy network tags are less secure than service accounts for firewall rules and do not provide identity-aware controls,

C is correct because IAP provides identity and context-based access control, and tying firewall rules to service accounts ensures only authorized applications can communicate with the database tier, aligning with zero-trust principles,

D is incorrect because Cloud NAT provides outbound internet access for private instances and is not an internal access control mechanism,

E is incorrect because Cloud DNS private zones resolve internal domain names, which does not enforce access control between tiers,

F is incorrect because a public load balancer distributes incoming internet traffic and does not secure internal tier-to-tier communication,

Question 3: Your team wants to automate the deployment of a complex VPC topology, including custom subnets, firewall rules, and Cloud Routers, ensuring the infrastructure is reproducible and version-controlled, Which tool is the most appropriate for this requirement,

B) Cloud Logging

C) Network Intelligence Center

D) Terraform

E) Cloud Trace

F) Cloud Source Repositories

Correct Answer: D

Explanation:

B is incorrect because Cloud Logging is used for collecting and analyzing log data, not for provisioning infrastructure,

C is incorrect because Network Intelligence Center is an observability tool for monitoring and troubleshooting network topology, not a provisioning tool,

D is correct because Terraform is a leading Infrastructure-as-Code (IaC) tool that allows you to define, automate, and version-control your Google Cloud network resources declaratively,

E is incorrect because Cloud Trace is a distributed tracing system for application latency, not a network infrastructure automation tool,

F is incorrect because while Cloud Source Repositories can store code, it is just a Git repository and does not actively deploy or provision the infrastructure itself,
