You are increasing your usage of Cloud VPN between on-premises and GCP, and you want to support more traffic than a single tunnel can handle. You want to increase the available bandwidth using Cloud VPN.
What should you do?
- A . Double the MTU on your on-premises VPN gateway from 1460 bytes to 2920 bytes.
- B . Create two VPN tunnels on the same Cloud VPN gateway that point to the same destination VPN gateway IP address.
- C . Add a second on-premises VPN gateway with a different public IP address. Create a second tunnel on the existing Cloud VPN gateway that forwards the same IP range, but points at the new on-premises gateway IP.
- D . Add a second Cloud VPN gateway in a different region than the existing VPN gateway. Create a new tunnel on the second Cloud VPN gateway that forwards the same IP range, but points to the existing on-premises VPN gateway IP address.
You are disabling DNSSEC for one of your Cloud DNS-managed zones. You removed the DS records from your zone file, waited for them to expire from the cache, and disabled DNSSEC for the zone. You receive reports that DNSSEC validating resolves are unable to resolve names in your zone.
What should you do?
- A . Update the TTL for the zone.
- B . Set the zone to the TRANSFER state.
- C . Disable DNSSEC at your domain registar.
- D . Transfer ownership of the domain to a new registar.
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?
- A . The traffic is matching the expected ingress rule.
- B . The traffic is matching the expected egress rule.
- C . The traffic is not matching the expected ingress rule.
- D . The traffic is not matching the expected egress rule.
You have configured Cloud CDN using HTTP(S) load balancing as the origin for cacheable content. Compression is configured on the web servers, but responses served by Cloud CDN are not compressed.
What is the most likely cause of the problem?
- A . You have not configured compression in Cloud CDN.
- B . You have configured the web servers and Cloud CDN with different compression types.
- C . The web servers behind the load balancer are configured with different compression types.
- D . You have to configure the web servers to compress responses even if the request has a Via header.
You have a web application that is currently hosted in the us-central1 region. Users experience high latency when traveling in Asia. You’ve configured a network load balancer, but users have not experienced a performance improvement. You want to decrease the latency.
What should you do?
- A . Configure a policy-based route rule to prioritize the traffic.
- B . Configure an HTTP load balancer, and direct the traffic to it.
- C . Configure Dynamic Routing for the subnet hosting the application.
- D . Configure the TTL for the DNS zone to decrease the time between updates.
You have an application running on Compute Engine that uses BigQuery to generate some results that are stored in Cloud Storage. You want to ensure that none of the application instances have external IP addresses.
Which two methods can you use to accomplish this? (Choose two.)
- A . Enable Private Google Access on all the subnets.
- B . Enable Private Google Access on the VPC.
- C . Enable Private Services Access on the VPC.
- D . Create network peering between your VPC and BigQuery.
- E . Create a Cloud NAT, and route the application traffic via NAT gateway.
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.
You are adding steps to a working automation that uses a service account to authenticate. You need to drive the automation the ability to retrieve files from a Cloud Storage bucket. Your organization requires using the least privilege possible.
What should you do?
- A . Grant the compute.instanceAdmin to your user account.
- B . Grant the iam.serviceAccountUser to your user account.
- C . Grant the read-only privilege to the service account for the Cloud Storage bucket.
- D . Grant the cloud-platform privilege to the service account for the Cloud Storage bucket.
You converted an auto mode VPC network to custom mode. Since the conversion, some of your Cloud Deployment Manager templates are no longer working. You want to resolve the problem.
What should you do?
- A . Apply an additional IAM role to the Google API’s service account to allow custom mode networks.
- B . Update the VPC firewall to allow the Cloud Deployment Manager to access the custom mode networks.
- C . Explicitly reference the custom mode networks in the Cloud Armor whitelist.
- D . Explicitly reference the custom mode networks in the Deployment Manager templates.
You have recently been put in charge of managing identity and access management for your organization. You have several projects and want to use scripting and automation wherever possible. You want to grant the editor role to a project member.
Which two methods can you use to accomplish this? (Choose two.)
- A . GetIamPolicy() via REST API
- B . setIamPolicy() via REST API
- C . gcloud pubsub add-iam-policy-binding Sprojectname –member user:Susername –role roles/editor
- D . gcloud projects add-iam-policy-binding Sprojectname –member user:Susername –role roles/editor
- E . Enter an email address in the Add members field, and select the desired role from the drop-down menu in the GCP Console.
