Start Configuring Network Security PracticeA security engineer needs to restrict access to Cloud Storage buckets so that only resources in a specific VPC can reach the Google APIs. Which Google Cloud service should be used?
Explanation: VPC Service Controls allows you to define a service perimeter that restricts access to Google Cloud APIs (like Cloud Storage) to only resources from authorized VPCs, preventing data exfiltration.
An organization wants to enforce a security policy that denies all egress traffic to the internet from all projects in the organization, except for traffic from a specific set of VMs tagged with 'allow-egress'. Which approach should be used?
Explanation: Hierarchical firewall policies are inherited down the resource hierarchy and can be enforced at the organization or folder level. They cannot be overridden at lower levels, making them suitable for organization-wide baseline rules.
A company uses VPC Service Controls to protect a BigQuery dataset. They need to allow an external on-premises application to query the dataset without being inside the service perimeter. The external application has a static IP address. Which configuration is required?
Explanation: VPC Service Controls access levels can define IP-based conditions. By creating an ingress rule that allows traffic from the specified IP address to access the BigQuery API, the external application can be authorized.
A DevOps team wants to automatically provision and renew SSL certificates for a global HTTPS load balancer. Which certificate management option should be used?
Explanation: Google-managed SSL certificates automatically provision and renew certificates for domains hosted on Google Cloud, ideal for load balancers without manual intervention.
An engineer needs to block a specific IP address from accessing an HTTPS load balancer. Which Cloud Armor rule should be used?
Explanation: Cloud Armor custom rules allow IP allow/deny lists. A deny rule with the specific IP address will block traffic.
