1Which IAM role provides the minimum permissions needed to view resources in a Google Cloud project without being able to modify them?
A.roles/editor
B.roles/viewer
C.roles/owner
D.roles/browser
Explanation: The roles/viewer (Viewer) basic role provides read-only access to all resources in a project. It allows listing and viewing resources but prevents any modifications. The roles/browser role only allows browsing the project hierarchy, not viewing resource details. roles/editor and roles/owner provide modification and full control permissions respectively, violating the principle of least privilege for read-only needs.
2What is the purpose of a VPC Service Controls perimeter?
A.To create a firewall around VM instances
B.To restrict data exfiltration from Google Cloud services by controlling API access boundaries
C.To encrypt all network traffic within a VPC
D.To manage DNS resolution for private zones
Explanation: VPC Service Controls creates a security perimeter around Google Cloud resources that restricts data movement across the boundary. Even users with proper IAM permissions cannot move data outside the perimeter through API calls. This prevents data exfiltration scenarios like copying Cloud Storage data to an unauthorized project. VPC Service Controls work at the API level, complementing VPC network-level controls and IAM permissions.
3Which Google Cloud service provides web application firewall (WAF) and DDoS protection capabilities?
A.Cloud NAT
B.Cloud Armor
C.Cloud IDS
D.Packet Mirroring
Explanation: Cloud Armor provides DDoS protection and WAF capabilities for applications served by Google Cloud load balancers. It supports custom security policies with IP-based, geo-based, and Layer 7 filtering rules. Preconfigured WAF rules protect against OWASP Top 10 threats including SQL injection and cross-site scripting. Cloud Armor also includes Adaptive Protection using ML to detect and mitigate L7 DDoS attacks automatically.
4What is the primary function of Security Command Center (SCC) in Google Cloud?
A.To manage encryption keys
B.To provide centralized security posture management and threat detection
C.To configure VPC firewall rules
D.To manage IAM policies
Explanation: Security Command Center (SCC) is Google Cloud's centralized security posture management platform. It provides asset inventory, vulnerability scanning, threat detection, and compliance monitoring across Google Cloud organizations. SCC aggregates findings from multiple security services (Web Security Scanner, Event Threat Detection, Container Threat Detection) into a unified dashboard. It helps security teams identify misconfigurations, vulnerabilities, and active threats.
5Which encryption option gives the customer full control over encryption key creation, storage, and lifecycle management?
A.Google default encryption
B.Customer-Managed Encryption Keys (CMEK)
C.Customer-Supplied Encryption Keys (CSEK)
D.Confidential Computing
Explanation: Customer-Supplied Encryption Keys (CSEK) give the customer full control — the keys are created, stored, and managed entirely outside Google Cloud. The customer provides the key with each API request, and Google uses it to encrypt/decrypt data but never stores the key. If the customer loses the key, the data is unrecoverable. CMEK keys are stored in Cloud KMS (managed by Google but controlled by customer), and default encryption uses Google-managed keys.
6Which IAM feature allows you to grant permissions that automatically expire after a specified time?
A.Service account keys
B.IAM Conditions with time-based expressions
C.Organization policies
D.Custom roles
Explanation: IAM Conditions allow you to add conditional expressions to IAM bindings, including time-based conditions that automatically expire permissions. For example, you can grant a contractor access that expires on a specific date or provide temporary elevated access for troubleshooting. Conditions use Common Expression Language (CEL) and can combine time, resource attributes, and request attributes. This supports the principle of just-in-time access.
7What does Binary Authorization enforce in a Google Cloud environment?
A.Authorization of binary file downloads from Cloud Storage
B.Deployment-time policy enforcement ensuring only trusted container images run on GKE
C.Two-factor authentication for all binary operations
D.Authorization of binary data streams through Pub/Sub
Explanation: Binary Authorization is a deploy-time security control for GKE that ensures only trusted, attested container images are deployed to clusters. It works with attestation policies that require images to be signed by trusted authorities (attestors) before they can be deployed. This prevents the deployment of unauthorized, unverified, or tampered container images. Binary Authorization integrates with Container Analysis for vulnerability scanning attestations and supports break-glass procedures for emergencies.
8Which Cloud KMS key protection level provides the highest level of hardware-based key protection?
A.SOFTWARE
B.HSM
C.EXTERNAL
D.EXTERNAL_VPC
Explanation: The HSM (Hardware Security Module) protection level in Cloud KMS stores and processes cryptographic keys within FIPS 140-2 Level 3 certified HSMs. Keys in HSM protection level never leave the hardware boundary in unencrypted form. SOFTWARE protection level uses software-based key management. EXTERNAL and EXTERNAL_VPC protection levels use keys managed outside Google Cloud via an External Key Manager (EKM), which provides cloud-external key residency rather than hardware-specific protection.
9A security engineer needs to detect if any Cloud Storage buckets in the organization are publicly accessible. Which service provides this capability?
A.Cloud Monitoring
B.Security Health Analytics in Security Command Center
C.Cloud Audit Logs
D.Access Transparency
Explanation: Security Health Analytics, a built-in service of Security Command Center, automatically scans for common misconfigurations including publicly accessible Cloud Storage buckets. It generates findings when it detects resources that violate security best practices. Findings include severity ratings and remediation guidance. Cloud Audit Logs record access events but do not proactively scan for misconfigurations. Cloud Monitoring tracks performance metrics, not security posture.
10What is the purpose of Organization Policy constraints in Google Cloud?
A.To define IAM roles for the organization
B.To enforce governance rules across the organization hierarchy
C.To manage billing across projects
D.To configure network routing between projects
Explanation: Organization Policy constraints enforce governance rules across the Google Cloud resource hierarchy (organization, folders, projects). They restrict which resources can be created, where they can be located, and how they can be configured. Examples include restricting VM external IPs, limiting resource locations to specific regions, and constraining service usage. Organization policies are inherited down the hierarchy and complement IAM by controlling what resources can do, not who can do things.
