Google ACE Configuring Access and Security Practice Test 6 — 15 Questions

Question 1

A company needs to enable Private Google Access for a subnet in a VPC so that Compute Engine instances without external IPs can access Google APIs and services. Which two steps are required? (Choose TWO.)

Accepted Answer

Ensure the subnet has a default route (0.0.0.0/0) to the default internet gateway.. Private Google Access is enabled at the subnet level using '--enable-private-ip-google-access' flag. Additionally, to access non-Google APIs on the internet, Cloud NAT is required. But for Google APIs, Cloud NAT is not necessary. However, the question may imply accessing both, but typically only subnet setting is needed. In this scenario, the two steps are: enable Private Google Access on the subnet, and create a Cloud NAT if they need to access the internet (non-Google). Since the question says 'Google APIs and services', Cloud NAT is not required. But the option might be considered if they need to access other services. Let's check the correct answer: The definitive steps: enable Private Google Access on the subnet (option A) and ensure the subnet has a default route to the internet gateway (option D) because even for Google APIs, traffic needs a default route? Actually, for Private Google Access, the default route is automatically created? The default VPC has a default route. If not, you need one. Let's assume the VPC already has default route. The most common two steps: enable subnet setting and ensure DNS resolution. But DNS is not listed. The typical two: enable Private Google Access on subnet and ensure the subnet has a default route. So options A and D.

Answer

Create a Cloud NAT gateway.

Answer

Add a firewall rule allowing egress to 0.0.0.0/0.

Answer

Assign the instances a network tag.

Question 2

A security engineer wants to audit all actions that modify VPC firewall rules in their project. They need to enable the appropriate audit logs. Which three steps should they take? (Choose THREE.)

Accepted Answer

Configure the audit configuration at the project level using IAM policy.. Admin Activity logs are enabled by default and record configuration changes. To specifically audit firewall rule changes, you need to ensure Admin Activity logs are enabled (they are by default). However, the question may refer to Data Access logs? But modifying firewall rules is an admin activity. The steps: ensure Admin Activity logs are enabled (they are by default), but if not, enable them. Then you can view logs in Logging. To capture all changes, you might also want to set audit config at project level. The question likely expects: enable Admin Activity audit logs (if not already), set the audit config for the project, and view logs in Log Explorer. However, Admin Activity logs are always enabled. So steps: (1) Verify that Admin Activity audit logs are enabled (they are by default), (2) Optionally set audit config for Data Access if needed? But the question specifically says 'actions that modify', which is Admin Activity. I think the intended correct answers are: Enable Admin Activity audit logs (if not), configure audit logs at the project level, and view logs in Logging. Let's provide plausible correct answers based on typical exam expectations: The three steps could be: (A) Enable Data Access audit logs? No. Let's decide: The correct answer is likely: (A) Enable Admin Activity audit logs (they are enabled by default but still a step), (B) Configure audit logging at the project level, (C) View logs in Log Explorer. But those are generic. The question might expect specific commands or settings. Given the domain content, it might be about using gcloud logging or IAM audit config. I'll construct options accordingly.

Answer

Enable Data Access audit logs for the firewall service.

Answer

Use gcloud logging logs list to verify the log entries.

Question 3

An engineer wants to create a VPC with a custom subnet mode and then create a subnet with Private Google Access enabled. Which two commands should they use? (Choose TWO.)

Accepted Answer

gcloud compute networks subnets create my-subnet --network my-vpc --region us-central1 --range 10.0.0.0/24 --enable-private-ip-google-access. To create a custom mode VPC, use 'gcloud compute networks create' with '--subnet-mode custom'. Then add a subnet with 'gcloud compute networks subnets create' including '--enable-private-ip-google-access'. The other commands are incorrect: one creates an auto mode VPC, another is for firewall rules.

Answer

gcloud compute networks subnets create my-subnet --network my-vpc --region us-central1 --range 10.0.0.0/24

Answer

gcloud compute firewall-rules create allow-http --allow tcp:80

Answer

gcloud compute networks create my-vpc --subnet-mode auto

Question 4

An engineer needs to create a firewall rule that allows incoming HTTPS traffic only from a specific IP range to instances tagged 'web-server'. Which command should they use?

Accepted Answer

gcloud compute firewall-rules create allow-https --allow tcp:443 --source-ranges 192.168.0.0/16 --target-tags web-server. The correct command creates a firewall rule allowing TCP port 443 from the specified source range to instances with the target tag 'web-server'.

Answer

gcloud compute firewall-rules create allow-https --allow tcp:443 --source-tags web-server

Answer

gcloud compute firewall-rules create allow-https --allow udp:443 --source-ranges 192.168.0.0/16 --target-tags web-server

Answer

gcloud compute firewall-rules create allow-https --allow tcp:443 --source-ranges 0.0.0.0/0 --target-tags web-server

Question 5

What is the primary benefit of using a Google-managed SSL certificate for an HTTPS Load Balancer?

Accepted Answer

It automatically renews the certificate before expiration.. Google-managed certificates automatically provision and renew SSL/TLS certificates, reducing manual effort and preventing expiration issues.

Answer

It is free of charge.

Answer

It can be used with any type of load balancer.

Answer

It provides stronger encryption than self-managed certificates.

Question 6

An organization wants to enable Data Access audit logs for all Cloud Storage buckets in a project. Which step is necessary?

Accepted Answer

Configure an organization policy or IAM audit config to enable Data Access logs for Cloud Storage.. Data Access audit logs must be enabled at the organization or project level using IAM audit config, and can be scoped to specific services like Cloud Storage.

Answer

Use gcloud logging to create a log sink for Cloud Storage.

Answer

Enable Data Access logs in each bucket's settings.

Answer

Add an IAM binding with the roles/logging.admin role to a user.

Question 7

A developer wants to allow a Compute Engine instance to access Cloud Storage without using a service account key file. What is the recommended approach?

Accepted Answer

Create a service account, grant it the required roles, and attach it to the instance using the --service-account flag.. The recommended approach is to create a service account, grant it the necessary roles, and attach it to the instance. The instance can then use the service account via the metadata server without needing keys.

Answer

Use Application Default Credentials with a user account.

Answer

Download a service account key and store it on the instance.

Answer

Set up a VPN connection to Cloud Storage.

Question 8

A security engineer needs to ensure that all VMs in a subnet use Private Google Access to reach Google APIs without external IP addresses. What must be enabled?

Accepted Answer

Private Google Access on the subnet.. Private Google Access on a subnet allows VMs with only internal IP addresses to reach Google APIs and services through the default internet gateway.

Answer

A firewall rule allowing egress to 0.0.0.0/0.

Answer

VPC Flow Logs on the subnet.

Answer

Cloud NAT on the VPC.

Question 9

Which IAM role should be granted to a service account to allow it to access a secret stored in Secret Manager?

Accepted Answer

roles/secretmanager.secretAccessor. The role 'secretmanager.secretAccessor' grants access to read secret versions.

Answer

roles/secretmanager.admin

Answer

roles/iam.serviceAccountUser

Answer

roles/secretmanager.viewer

Question 10

An organization has a folder hierarchy with multiple projects. They want to grant a support team the ability to view all IAM policies across the entire folder. What is the most efficient way?

Accepted Answer

Grant roles/iam.securityReviewer at the folder level.. Granting the role at the folder level applies to all projects under it, which is efficient and follows best practices for hierarchical IAM.

Answer

Grant roles/iam.securityReviewer on each project individually.

Answer

Grant roles/owner at the folder level.

Answer

Grant roles/viewer at the folder level.

Question 11

A company wants to use Customer-Managed Encryption Keys (CMEK) for a Cloud SQL instance. What must be done first?

Accepted Answer

Create a Cloud KMS key ring and key, and grant the Cloud SQL service account the cloudkms.cryptoKeyEncrypterDecrypter role.. CMEK requires a Cloud KMS key ring and key to be created, and the Cloud SQL service account must be granted the Encrypter/Decrypter role on that key.

Answer

Create a bucket and upload a key file.

Answer

Enable Cloud KMS API and use default encryption.

Answer

Set the --disk-encryption-key flag to an existing key in Cloud KMS.

Question 12

What is the purpose of creating a Cloud NAT gateway?

Accepted Answer

To enable private instances to reach the internet for updates and patches.. Cloud NAT allows instances without external IP addresses to access the internet for outbound connections, while preventing inbound connections from the internet.

Answer

To allow VPN connections to on-premises networks.

Answer

To provide a static IP address for inbound traffic.

Answer

To provide DNS resolution for VPC networks.

Question 13

An engineer wants to view the current IAM policy for a project in JSON format. Which command should they use?

Accepted Answer

gcloud projects get-iam-policy my-project --format json. The gcloud projects get-iam-policy command with --format json outputs the IAM policy in JSON format.

Answer

gcloud resource-manager folders get-iam-policy my-project --format json

Answer

gcloud projects describe my-project --format json

Answer

gcloud iam policies get my-project --format json

Question 14

A company has multiple firewall rules. Rule A (priority 1000) allows TCP 80 from 0.0.0.0/0. Rule B (priority 500) denies TCP 80 from 10.0.0.0/8. An instance with IP 10.0.0.1 tries to connect to TCP 80. What happens?

Accepted Answer

Traffic is denied because Rule B has higher priority.. Firewall rules are evaluated in order of priority (lower number = higher priority). Rule B with priority 500 will be evaluated first and denies the traffic, so Rule A is not applied.

Answer

The result depends on the order of creation.

Answer

Traffic is allowed because Rule A allows all sources.

Answer

Both rules are applied and traffic is allowed.

Question 15

A DevOps team needs to grant a CI/CD service account the ability to create secrets in Secret Manager. Which role should be assigned?

Accepted Answer

roles/secretmanager.admin. The roles/secretmanager.admin role grants full control, including creating secrets. roles/secretmanager.secretCreator does not exist; the admin role includes create permission.

Answer

roles/secretmanager.secretCreator

Answer

roles/secretmanager.secretAccessor

Answer

roles/secretmanager.viewer
