Configuring access within a cloud solution environment and Ensuring data protection typically account for a significant portion of the exam. However, all five domains are equally important for real-world security operations, so balanced preparation across all topics is essential for both passing the exam and building practical expertise.
Access control defines who can do what, network security controls where data flows, encryption protects the data itself, operations monitoring detects threats, and compliance ensures everything meets regulations. In practice, these domains work together: you configure access policies, enforce them through network rules, encrypt sensitive data, monitor for violations, and audit the entire process for compliance.
Practical experience with Google Cloud services is highly beneficial. Prioritize labs that cover IAM role assignment, VPC and firewall configuration, Cloud KMS for encryption, and Cloud Audit Logs setup. Even if you lack extensive production experience, working through Google Cloud's hands-on tutorials and practice environments will significantly improve your ability to answer scenario-based questions.
Candidates often overlook the principle of least privilege when designing access policies, confuse firewall rule directions (ingress vs. egress), or fail to consider encryption requirements for different data sensitivity levels. Additionally, some candidates underestimate the importance of audit logging and compliance documentation. Review each domain's best practices and practice explaining your security decisions in scenario questions.
In the final week, focus on weak areas identified during practice tests rather than re-reading all topics. Complete one full-length timed practice test to assess pacing and confidence. Review scenario-based questions to ensure you understand the reasoning behind correct answers. On the day before the exam, do a light review of key terminology and take a short practice quiz to stay sharp without overloading.
You work for a large organization that recently implemented a 100GB Cloud Interconnect connection between your Google Cloud and your on-premises edge router. While routinely checking the connectivity, you noticed that the connection is operational but there is an error message that indicates MACsec is operationally down. You need to resolve this error. What should you do?
MACsec (Media Access Control Security) relies on a shared secret (a pre-shared key, made up of a Connectivity Key Name, CKN, and Connectivity Association Key, CAK) to establish a secure session between the two endpoints. If the session is 'operationally down,' it indicates a cryptographic mismatch.
Extracts:
'MACsec is operationally down on my Cloud Interconnect connection... The issue could be caused by one of the following: The active keys on your on-premises router and Google's edge routers don't match.' (Source 3.1)
The troubleshooting guide further specifies checking that the 'active CKN, CAK, and start times on your on-premises router match the values that MACsec for Cloud Interconnect displays.' (Source 3.1)
Therefore, the primary and most common step to resolve a 'MACsec is operationally down' status is to verify that the cryptographic keys (the pre-shared key) are correctly configured and match on both the on-premises and Google Cloud routers.
Users are reporting an outage on your public-facing application that is hosted on Compute Engine. You suspect that a recent change to your firewall rules is responsible. You need to test whether your firewall rules are working properly. What should you do?
Enable Firewall Rules Logging on the latest rules that were changed. Use Logs Explorer to analyze whether the rules are working correctly:
Enable Firewall Rules Logging for the specific firewall rules in question through the Google Cloud Console.
Once logging is enabled, use Logs Explorer to filter and review the firewall logs.
Analyze the logs to determine if the rules are allowing or blocking traffic as intended, identifying any misconfigurations or issues.

Your company has deployed an artificial intelligence model in a central project. As this model has a lot of sensitive intellectual property and must be kept strictly isolated from the internet, you must expose the model endpoint only to a defined list of projects in your organization. What should you do?
The problem requires exposing a sensitive AI model endpoint internally (strictly isolated from the internet) to a defined list of projects within the organization.
Internal Exposure and Isolation: An 'internal Application Load Balancer' is suitable for exposing services within your VPC network, ensuring they are not accessible from the internet.
Private Service Connect (PSC): This is the key technology for securely and privately exposing services from one VPC network (the service producer, where the model is) to other VPC networks (the service consumers, the defined list of projects) within the same or different organizations. PSC allows consumers to access services using internal IP addresses, with traffic remaining on Google's private network. You can configure a service attachment that points to the internal load balancer, and then permit specific consumer projects to connect to this service attachment.Extract Reference: 'Private Service Connect is a capability of Google Cloud networking that allows consumers to access managed services privately from inside their VPC network. Similarly, it allows managed service producers to host these services in their own separate VPC networks and offer a private connection to their consumers.' (Google Cloud Documentation: 'Private Service Connect | VPC' - https://cloud.google.com/vpc/docs/private-service-connect)
Extract Reference: 'Private Service Connect endpoints are internal IP addresses in a consumer VPC network that can be directly accessed by clients in that network. Endpoints are created by deploying a forwarding rule that references a service attachment or a bundle of Google APIs.' (Google Cloud Documentation: 'About Private Service Connect | VPC' - https://cloud.google.com/vpc/docs/private-service-connect)
Extract Reference: 'Private Service Connect can be used to access managed services that are owned by Google, third-party software as a service (SaaS) companies, or other teams within the consumer's own company. Both published services and Google APIs can be targets of Private Service Connect.' (Google Cloud Documentation: 'About Private Service Connect | VPC' - https://cloud.google.com/vpc/docs/private-service-connect)
Let's evaluate the other options:
A . Shared VPC and central firewall rules: While Shared VPC centralizes network management, it does not provide a direct managed service exposure mechanism like PSC for a model endpoint to specific projects. It's more about sharing subnets and network resources. Administering all firewall rules centrally would also not meet the need for exposing only this specific model to a defined list of projects in a managed, private service pattern.
B . Activate Private Google Access (PGA): Private Google Access allows VMs without external IP addresses to access Google APIs and services (like Cloud Storage, BigQuery, etc.) privately from within their VPC network. It's for consuming Google services, not for exposing custom services hosted in a Google Cloud project to other projects.
D . External Application Load Balancer + Cloud Armor: An 'external Application Load Balancer' exposes the service to the internet. While Cloud Armor can restrict access based on IP addresses, it still involves internet exposure, which contradicts the 'strictly isolated from the internet' requirement. Restricting to 'Google Cloud IP addresses' doesn't guarantee access only to a defined list of projects and still exposes the service externally.
Therefore, creating an internal Application Load Balancer and exposing it via Private Service Connect is the most suitable and secure solution for this scenario.
You want to set up a secure, internal network within Google Cloud for database servers. The servers must not have any direct communication with the public internet. What should you do?
To ensure servers do not have any direct communication with the public internet, they must be configured without a public IP address.
VPC and Private Subnet: A Virtual Private Cloud (VPC) network provides the isolated, internal network structure. A subnet is the logical partition within the VPC.
Private IP Address: Assigning only a private IP address to the database servers ensures they can only communicate internally within the VPC (or connected on-premises networks) and cannot directly connect to or be connected from the public internet.
Extracts:
'Resources in a VPC network can be assigned two types of IP addresses: internal (private) and external (public). If a VM is not assigned an external IP address, it can only communicate internally with other resources in the VPC network...' (Source 6.1)
Option A and C involve assigning a public IP address, which violates the 'no direct communication with the public internet' rule. Option D uses NAT to provide outbound internet connectivity, which also violates the requirement.
Your organization operates in a highly regulated industry and uses multiple Google Cloud services. You need to identify potential risks to regulatory compliance. Which situation introduces the greatest risk?
The greatest risk to regulatory compliance stems from violations of the Principle of Least Privilege and the lack of enforced configuration/hardening standards. Regulatory compliance typically mandates strict control over infrastructure and sensitive systems.
Option A (Greatest Risk): Broad IAM roles violate the principle of least privilege, which is a fundamental compliance requirement (e.g., ISO 27001, PCI DSS). Allowing users to create and manage critical resources (VMs) without a pre-defined hardening process means new resources can be deployed in a non-compliant, vulnerable state (e.g., unpatched, open ports, default configurations). This lack of control and excessive access poses an immediate and high risk to the security posture and compliance.
Option B (Risk Reduction): Uniform bucket-level access reduces risk by enforcing a consistent policy for all objects in a bucket, preventing individual object-level IAM policies that can lead to misconfigurations and unauthorized access.
Option C (Risk Reduction): Mandating CMEK is a security-enhancing control that reduces risk by giving the customer exclusive control over the encryption keys for sensitive data, which is a common requirement in regulated environments.
Option D (Necessary Control): Providing the audit team access to Cloud Audit Logs is a compliance requirement for monitoring, accountability, and forensic investigation, not a risk.
Extracts:
'The principle of least privilege states that a user should only be granted the minimum permissions necessary to perform their work. Overly permissive roles introduce a significant risk.' (Source 5.1)
'Non-compliant configurations, such as unhardened virtual machines or resources with insufficient security controls, are a major source of security breaches and regulatory findings.' (Source 5.2)
