Cloud Digital Leader Google Cloud Products and Services Practice Test 7 — 15 Questions

Question 1

A media company needs to stream live video to global viewers with low latency. They also want to protect against DDoS attacks. Which combination of Google Cloud networking services should they use?

Accepted Answer

Cloud CDN and Cloud Armor. Cloud CDN caches content at edge locations for low-latency delivery, and Cloud Armor provides DDoS protection and WAF capabilities at the edge.

Answer

Cloud Interconnect and Cloud VPN

Answer

Cloud DNS and Cloud Armor

Question 2

A security team wants to restrict access to a Cloud Storage bucket so that only Compute Engine VMs in the same VPC network can read objects. The VMs do not have public IP addresses. Which configuration should they use?

Accepted Answer

Enable Private Google Access on the subnet and use VPC Service Controls to limit bucket access to the VPC.. Private Google Access allows VMs without external IPs to access Google APIs and services via the VPC network. Combined with VPC Service Controls and bucket IAM, this ensures only VMs in the VPC can access the bucket.

Answer

Assign external IPs to the VMs and use firewall rules.

Answer

Create a bucket with uniform bucket-level access and grant the `storage.objectViewer` role to `allUsers`.

Answer

Use a Cloud VPN to connect the VMs to the bucket.
