Question # 24

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

Your company’s on-premises network is connected to a VPC using a Cloud VPN tunnel. You have a static route of 0.0.0.0/0 with the VPN tunnel as its next hop defined in the VPC. All internet bound traffic currently passes through the on-premises network. You configured Cloud NAT to translate the primary IP addresses of Compute Engine instances in one region. Traffic from those instances will now reach the internet directly from their VPC and not from the on-premises network. Traffic from the virtual machines (VMs) is not translating addresses as expected. What should you do?

Options:

A.

Lower the TCP Established Connection Idle Timeout for the NAT gateway.

B.

Add firewall rules that allow ingress and egress of the external NAT IP address, have a target tag that is on the Compute Engine instances, and have a priority value higher than the priority value of the default route to the VPN gateway.

C.

Add a default static route to the VPC with the default internet gateway as the next hop, the network tag associated with the Compute Engine instances, and a higher priority than the priority of the default route to the VPN tunnel.

D.

Increase the default min-ports-per-vm setting for the Cloud NAT gateway.

Question # 27

You have enabled HTTP(S) load balancing for your application, and your application developers have reported that HTTP(S) requests are not being distributed correctly to your Compute Engine Virtual Machine instances. You want to find data about how the request are being distributed.

Which two methods can accomplish this? (Choose two.)

Options:

A.

On the Load Balancer details page of the GCP Console, click on the Monitoring tab, select your backend service, and look at the graphs.

B.

In Stackdriver Error Reporting, look for any unacknowledged errors for the Cloud Load Balancers service.

C.

In Stackdriver Monitoring, select Resources > Metrics Explorer and search for https/request_bytes_count metric.

D.

In Stackdriver Monitoring, select Resources > Google Cloud Load Balancers and review the Key Metrics graphs in the dashboard.

E.

In Stackdriver Monitoring, create a new dashboard and track the https/backend_request_count metric for the load balancer.

Question # 28

There are two established Partner Interconnect connections between your on-premises network and Google Cloud. The VPC that hosts the Partner Interconnect connections is named "vpc-a" and contains three VPC subnets across three regions, Compute Engine instances, and a GKE cluster. Your on-premises users would like to resolve records hosted in a Cloud DNS private zone following Google-recommended practices. You need to implement a solution that allows your on-premises users to resolve records that are hosted in Google Cloud. What should you do?

Options:

A.

Associate the private zone to "vpc-a." Create an outbound forwarding policy and associate the policy to "vpc-a." Configure the on-premises DNS servers to forward queries for the private zone to the entry point addresses created when the policy was attached to "vpc-a."

B.

Configure a DNS proxy service inside one of the GKE clusters. Expose the DNS proxy service in GKE as an internal load balancer. Configure the on-premises DNS servers to forward queries for the private zone to the IP address of the internal load balancer.

C.

Use custom route advertisements to announce 169.254.169.254 via BGP to the on-premises environment. Configure the on-premises DNS servers to forward DNS requests to 169.254.169.254.

D.

Associate the private zone to "vpc-a." Create an inbound forwarding policy and associate the policy to "vpc-a." Configure the on-premises DNS servers to forward queries for the private zone to the entry point addresses created when the policy was attached to "vpc-a."

Question # 29

You have a storage bucket that contains two objects. Cloud CDN is enabled on the bucket, and both objects have been successfully cached. Now you want to make sure that one of the two objects will not be cached anymore, and will always be served to the internet directly from the origin.

What should you do?

Options:

A.

Ensure that the object you don’t want to be cached anymore is not shared publicly.

B.

Create a new storage bucket, and move the object you don’t want to be checked anymore inside it. Then edit the bucket setting and enable the private attribute.

C.

Add an appropriate lifecycle rule on the storage bucket containing the two objects.

D.

Add a Cache-Control entry with value private to the metadata of the object you don’t want to be cached anymore. Invalidate all the previously cached copies.

Options:

A.

VPC peering

B.

Shared VPC

C.

Cloud VPN

D.

Dedicated Interconnect

Question # 31

Question:

Recently, your networking team enabled Cloud CDN for one of the external-facing services that is exposed through an external Application Load Balancer. The application team has already defined which content should be cached within the responses. Upon testing the load balancer, you did not observe any change in performance after the Cloud CDN enablement. You need to resolve the issue. What should you do?

Options:

A.

Configure the CACHE_MAX_STATIC caching mode on Cloud CDN to ensure Cloud CDN caches content depending on responses from the backends.

B.

Configure the USE_ORIGIN_HEADERS caching mode on Cloud CDN to ensure Cloud CDN caches content based on response headers from the backends.

C.

Configure the CACHE_ALL_STATIC caching mode on Cloud CDN to ensure Cloud CDN caches all static content as well as content defined by the backends.

D.

Configure the FORCE_CACHE_ALL caching mode on Cloud CDN to ensure all appropriate content is cached.
