Question 28

You have an application hosted on a Compute Engine virtual machine instance that cannot communicate with a resource outside of its subnet. When you review the flow and firewall logs, you do not see any denied traffic listed.

During troubleshooting you find:

• Flow logs are enabled for the VPC subnet, and all firewall rules are set to log.

• The subnetwork logs are not excluded from Stackdriver.

• The instance that is hosting the application can communicate outside the subnet.

• Other instances within the subnet can communicate outside the subnet.

• The external resource initiates communication.

What is the most likely cause of the missing log lines?

Options:

The traffic is matching the expected ingress rule.

The traffic is matching the expected egress rule.

The traffic is not matching the expected ingress rule.

The traffic is not matching the expected egress rule.

Question 29

Your company has defined a resource hierarchy that includes a parent folder with subfolders for each department. Each department defines their respective project and VPC in the assigned folder and has the appropriate permissions to create Google Cloud firewall rules. The VPCs should not allow traffic to flow between them. You need to block all traffic from any source, including other VPCs, and delegate only the intra-VPC firewall rules to the respective departments. What should you do?

Options:

Create a VPC firewall rule in each VPC to block traffic from any source, with priority 0.

Create a VPC firewall rule in each VPC to block traffic from any source, with priority 1000.

Create two hierarchical firewall policies per department's folder with two rules in each: a high-priority rule that matches traffic from the private CIDRs assigned to the respective VPC and sets the action to allow, and another lower-priority rule that blocks traffic from any other source.

Create two hierarchical firewall policies per department's folder with two rules in each: a high-priority rule that matches traffic from the private CIDRs assigned to the respective VPC and sets the action to goto_next, and another lower-priority rule that blocks traffic from any other source.

Question 30

You have deployed a proof-of-concept application by manually placing instances in a single Compute Engine zone. You are now moving the application to production, so you need to increase your application availability and ensure it can autoscale.

How should you provision your instances?

Options:

Create a single managed instance group, specify the desired region, and select Multiple zones for the location.

Create a managed instance group for each region, select Single zone for the location, and manually distribute instances across the zones in that region.

Create an unmanaged instance group in a single zone, and then create an HTTP load balancer for the instance group.

Create an unmanaged instance group for each zone, and manually distribute the instances across the desired zones.

Question 31

Question:

Options:

Configure a global external Application Load Balancer with a Service Extension that points to an application running in a VM, which controls which requests go to each application.

Configure a global external Application Load Balancer with weighted traffic splitting.

Configure two separate global external Application Load Balancers, and use Cloud DNS geolocation routing policies.

Configure a global external Application Load Balancer with weighted request mirroring.
