Question 25

In order to provide subnet level isolation, you want to force instance-A in one subnet to route through a security appliance, called instance-B, in another subnet.

What should you do?

Options:

A.

Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with no tag.

B.

Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with a tag applied to instance-A.

C.

Delete the system-generated subnet route and create a specific route to instance-B with a tag applied to instance-A.

D.

Move instance-B to another VPC and, using multi-NIC, connect instance-B's interface to instance-A's network. Configure the appropriate routes to force traffic through to instance-A.

Question 26

In your project my-project, you have two subnets in a Virtual Private Cloud (VPC): subnet-a with IP range 10.128.0.0/20 and subnet-b with IP range 172.16.0.0/24. You need to deploy database servers in subnet-a. You will also deploy the application servers and web servers in subnet-b. You want to configure firewall rules that only allow database traffic from the application servers to the database servers. What should you do?

Options:

A.

Create network tag app-server and service account sa-db@my-project.iam.gserviceaccount.com. Add the tag to the application servers, and associate the service account with the database servers. Run the following command:

gcloud compute firewall-rules create app-db-firewall-rule \

--action allow \

--direction ingress \

--rules top:3306 \

--source-tags app-server \

--target-service-accounts sa-db@my-<

B.

Create service accounts sa-app@my-project.iam.gserviceaccount.com and sa-db@my-project.iam.gserviceaccount.com. Associate service account sa-app with the application servers, and associate the

service account sa-db with the database servers. Run the following command:

gcloud compute firewall-rules create app-db-firewall-ru

--allow TCP:3306 \

--source-service-accounts sa-app@democloud-idp-

demo.iam.gserv

C.

Create service accounts sa-app@my-project.iam.gserviceaccount.com and sa-db@my-project.iam.gserviceaccount.com. Associate the service account sa-app with the application servers, and associate

the service account sa-db with the database servers. Run the following command:

gcloud compute firewall-rules create app-db-firewall-ru

--allow TCP:3306 \

--source-ranges 10.128.0.0/20 \

--source-service-accounts

D.

Create network tags app-server and db-server. Add the app-server tag to the application servers, and add the db-server tag to the database servers. Run the following command:

gcloud compute firewall-rules create app-db-firewall-rule \

--action allow \

--direction ingress \

--rules tcp:3306 \

--source-ranges 10.128.0.0/20 \

--source-tags app-server \

--target-tags db-server
