Question # 49

You are troubleshooting an issue where your organization's Cloud HA VPN is disconnected from your on-premises router for approximately 10 seconds before reestablishing the tunnel. The issue regularly occurs every few hours. You notice that the HA VPN logs show an entry of Received SA_DELETE when this issue occurs. You need to resolve this issue and prevent future VPN downtime from impacting your production applications. What should you do?

Q Update the pre-shared key (PSK) of the on-premises routerâ€™s VPN tunnel configuration to match the PSK of the Cloud HA VPN.

Q Update the on-premises routerâ€™s BGP router ID to reflect the link-local IP peer address assigned by Cloud Router.

Q Update the on-premises routerâ€™s Phase 1 and Phase 2 lifetime IKE parameters to match the values in the Cloud HA VPN documentation.

Q Update the on-premises routerâ€™s Diffie-Hellman groups and cipher proposal list to match the values in the Cloud HA VPN documentation.

You need to enable Cloud CDN for all the objects inside a storage bucket. You want to ensure that all the object in the storage bucket can be served by the CDN.

What should you do in the GCP Console?

Create a new cloud storage bucket, and then enable Cloud CDN on it.

Create a new TCP load balancer, select the storage bucket as a backend, and then enable Cloud CDN on the backend.

Create a new SSL proxy load balancer, select the storage bucket as a backend, and then enable Cloud CDN on the backend.

Create a new HTTP load balancer, select the storage bucket as a backend, enable Cloud CDN on the backend, and make sure each object inside the storage bucket is shared publicly.

Question # 52

Your organization recently exposed a set of services through a global external Application Load Balancer. After conducting some testing, you observed that responses would intermittently yield a non-HTTP 200 response. You need to identify the error. What should you do? (Choose 2 answers)

Delete the load balancer and backend services. Create a new passthrough Network Load Balancer. Configure a failover group of VMs for the backend.

Access a VM in the VPC through SSH and try to access a backend VM directly. If the request is successful from the VM, increase the quantity of backends.

Enable and review the health check logs. Review the error responses in Cloud Logging.

Validate the health of the backend service. Enable logging for the backend service and identify the error response in Cloud Logging. Determine the cause of the error by reviewing the statusDetails log field.

Validate the health of the backend service. Enable logging on the load balancer and identify the error response in Cloud Logging. Determine the cause of the error by reviewing the statusDetails log field.

Question # 53

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?

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

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

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.

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

You have recently taken over responsibility for your organization's Google Cloud network security configurations. You want to review your Cloud Next Generation Firewall (Cloud NGFW) configurations to ensure that there are no rules allowing ingress traffic to your VMs and services from the internet. You want to avoid manual work. What should you do?

Use Firewall Insights, and enable insights for overly permissive rules.

Review Network Analyzer insights on the VPC network category.

Export all your Cloud NGFW rules into a CSV file and search for 0.0.0.0/0.

Run Connectivity Tests from multiple external sources to confirm that traffic is not allowed to ingress to your most critical services in Google Cloud.
