Question 1

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?

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.

Answer: B

Question 2

You have several VMs across multiple VPCs in your cloud environment that require access to internetendpoints. These VMs cannot have public IP addresses due to security policies, so you plan to use CloudNAT to provide outbound internet access. Within your VPCs, you have several subnets in each region. Youwant to ensure that only specific subnets have access to the internet through Cloud NAT. You want to avoidany unintentional configuration issues caused by other administrators and align to Google-recommendedpractices. What should you do?

A : Deploy Cloud NAT in each VPC and configure a custom source range that includes the allowed subnets. Configure Cloud NAT rules to only permit the allowed subnets to egress through Cloud NAT.

B : Create a firewall rule in each VPC at priority 500 that targets all instances in the network and denies egress to the internet (0.0.0.0/0). Create a firewall rule at priority 300 that targets all instances in the network, has a source filter that maps to the allowed subnets, and allows egress to the internet (0.0.0.0 /0). Deploy Cloud NAT and configure all primary and secondary subnet source ranges.

C : Create a firewall rule in each VPC at priority 500 that targets all instances in the network and denies egress to the internet (0.0.0.0/0). Create a firewall rule at priority 300 that targets all instances in the network, has a source filter that maps to the allowed subnets, and allows egress to the internet (0.0.0.0 /0). Deploy Cloud NAT and configure a custom source range that includes the allowed subnets.

D : Create a constraints/compute.restrictCloudNATUsage organizational policy constraint. Attach the constraint to a folder that contains the associated projects. Configure the allowedValues to only contain the subnets that should have internet access. Deploy Cloud NAT and select only the allowed subnets.

Answer: D

Answer: D

Question 4

Your organization recently re-architected your cloud environment to use Network Connectivity Center. However, an error occurred when you tried to add a new VPC named vpc-dev as a spoke. The error indicated that there was an issue with an existing spoke and the IP space of a VPC named vpc-pre-prod. You must complete the migration quickly and efficiently. What should you do?

A : Remove the conflicting VPC spoke for vpc-pre-prod from the set of VPC spokes in Network Connectivity Center. Add the VPC spoke for vpc-dev. Add the previously removed vpc-pre-prod as a VPC spoke

B : Delete the VMs associated with the conflicting subnets, then delete the conflicting subnets in vpc-dev. Recreate the subnets with a new IP range and redeploy the previously deleted VMs in the new subnets. Add the VPC spoke for vpc-dev.

C : Exclude the conflicting IP range by using the --exclude-export-ranges flag when creating the VPC spoke for vpc-dev.

D : Exclude the conflicting IP range by using the --exclude-export-ranges flag in the hub when attaching the VPC spoke for vpc-dev.

Answer: A
