Question 101

You are designing a shared VPC architecture. Your network and security team has strict controls over which routes are exposed between departments. Your Production and Staging departments can communicate with each other, but only via specific networks. You want to follow Google- recommended practices.
How should you design this topology?

A.Create 2 shared VPCs within the shared VPC Host Project, and enable VPC peering between them.
Use firewall rules to filter access between the specific networks.
B.Create 2 shared VPCs within the shared VPC Host Project, and create a Cloud VPN/Cloud Router between them.
Use Flexible Route Advertisement (FRA) to filter access between the specific networks.
C.Create 2 shared VPCs within the shared VPC Service Project, and create a Cloud VPN/Cloud Router between them.
Use Flexible Route Advertisement (FRA) to filter access between the specific networks.
D.Create 1 VPC within the shared VPC Host Project, and share individual subnets with the Service Projects to filter access between the specific networks.

Question 102

You have the following firewall ruleset applied to all instances in your Virtual Private Cloud (VPC):

You need to update the firewall rule to add the following rule to the ruleset:

You are using a new user account. You must assign the appropriate identity and Access Management (IAM) user roles to this new user account before updating the firewall rule. The new user account must be able to apply the update and view firewall logs. What should you do?

A.Assign the compute.orgSecurityPolicyAdmin and logging.bucketWriter role to the new user account.Apply the new firewall rule with a priority of 150.
B.Assign the compute.securityAdmin and logging.bucketWriter role to the new user account. Apply the new firewall rule with a priority of 150.
C.Assign the compute.securityAdmin and logging.viewer rule to the new user account. Apply the new firewall rule with a priority of 50.
D.Assign the compute.orgSecurityPolicyAdmin and logging.viewer role to the new user account. Apply the new firewall rule with a priority of 50.

Question 103

Your organization has a single project that contains multiple Virtual Private Clouds (VPCs). You need to secure API access to your Cloud Storage buckets and BigQuery datasets by allowing API access only from resources in your corporate public networks. What should you do?

A.Create a VPC Service Controls perimeter for your project with an access context policy that allows your corporate public network IP ranges.
B.Create an access context policy that allows your VPC and corporate public network IP ranges, and then attach the policy to Cloud Storage and BigQuery.
C.Create a VPC Service Controls perimeter for each VPC with an access context policy that allows your corporate public network IP ranges.
D.Create a firewall rule to block API access to Cloud Storage and BigQuery from unauthorized networks.

Question 104

You have the networking configuration shown in the diagram. A pair of redundant Dedicated Interconnect connections (int-Igal and int-Iga2) terminate on the same Cloud Router. The Interconnect connections terminate on two separate on-premises routers. You are advertising the same prefixes from the Border Gateway Protocol (BGP) sessions associated with the Dedicated Interconnect connections. You need to configure one connection as Active for both ingress and egress traffic. If the active Interconnect connection fails, you want the passive Interconnect connection to automatically begin routing all traffic Which two actions should you take to meet this requirement? (Choose Two)

A.Configure the advertised route priority > 10,200 on the active Interconnect connection.
B.Advertise a lower MED on the passive Interconnect connection from the on-premises router
C.Configure the advertised route priority as 200 for the BGP session associated with the active Interconnect connection.
D.Configure the advertised route priority as 200 for the BGP session associated with the passive Interconnect connection.
E.Advertise a lower MED on the active Interconnect connection from the on-premises router

Correct Answer: C,E

This answer meets the requirement of configuring one connection as Active for both ingress and egress traffic, and enabling automatic failover to the passive connection in case of failure. The reason is:
The advertised route priority is a value that Cloud Router uses to set the route priority when advertising routes to your on-premises router. The lower the value, the higher the priority1. By setting the advertised route priority as 200 for the active connection, you ensure that it has a higher priority than the passive connection, which has the default value of 1001. This way, your on-premises router will prefer the routes from the active connection over the passive one for ingress traffic.
The MED (Multi-Exit Discriminator) is a value that your on-premises router uses to indicate its preference for receiving traffic from Cloud Router. The lower the value, the higher the preference2. By advertising a lower MED on the active connection from your on-premises router, you ensure that Cloud Router will prefer sending traffic to the active connection over the passive one for egress traffic.
If the active connection fails, Cloud Router will stop receiving routes from it and will start using the routes from the passive connection for egress traffic. Similarly, your on-premises router will stop receiving routes with priority 200 from the active connection and will start using the routes with priority 100 from the passive connection for ingress traffic. This achieves automatic failover without any manual intervention.
Option A is incorrect because setting the advertised route priority > 10,200 on the active connection would deprioritize it globally in your VPC network, which is not what you want1. Option B is incorrect because advertising a lower MED on the passive connection would make Cloud Router prefer sending traffic to it over the active one, which is not what you want2. Option D is incorrect because setting the advertised route priority as 200 for both connections would make them equally preferred by your on-premises router, which is not what you want1.

Question 105

You have the networking configuration shown. In the diagram Two VLAN attachments associated With two Dedicated Interconnect connections terminate on the same Cloud Router (mycloudrouter). The Interconnect connections terminate on two separate on-premises routers. You advertise the same prefixes from the Border Gateway Protocol (BOP) sessions associated with each Of the VLAN attachments.
You notice an asymmetric traffic flow between the two Interconnect connections. Which of the following actions should you take to troubleshoot the asymmetric traffic flow?

A.From the Google Cloud console, navigate to the Hybrid Connectivity select the Cloud Router, and view BGP sessions.
B.From the Cloud CLI, run gcloud compute -protect_ID router get-status mycloudrouter --region REGION and review the results.
C.From the Google Cloud console, navigate to Cloud Logging to view VPC Flow Logs and review the results
D.From the Cloud CLI. run gcloud compute routers describe mycloudrouter
--region REGION and review the results
