QUESTION 3 OF 12

Cymbal Direct developers have written a new application. Based on initial usage estimates, you decide to run the application on Compute Engine instances with 15 Gb of RAM and 4 CPUs. These instances store persistent data locally. After the application runs for several months, historical data indicates that the application requires 30 Gb of RAM. Cymbal Direct management wants you to make adjustments that will minimize costs. What should you do?

Stop the instance, and then use the command gcloud compute instances set-machine-type VM_NAME –machine-type 2-custom-4-30720. Set the instance’s metadata to: preemptible: true. Start the instance again.

QUESTION 4 OF 12

You are creating a new project. You plan to set up a Dedicated interconnect between two of your data centers in the near future and want to ensure that your resources are only deployed to the same regions where your data centers are located. You need to make sure that you don’t have any overlapping IP addresses that could cause conflicts when you set up the interconnect. You want to use RFC 1918 class B address space. What should you do?

Create a new project, leave the default network in place, and then use the default 10.x.x.x network range to create subnets in your desired regions.

Create a new project, delete the default VPC network, set up an auto mode VPC network, and then use the default 10.x.x.x network range to create subnets in your desired regions.

Create a new project, delete the default VPC network, set up a custom mode VPC network, and then use IP addresses in the 172.16.x.x address range to create subnets in your desired regions.Correct Answer

Create a new project, delete the default VPC network, set up the network in custom mode, and then use IP addresses in the 192.168.x.x address range to create subnets in your desired zones. Use VPC Network Peering to connect the zones in the same region to create regional networks.

QUESTION 5 OF 12

Cymbal Direct is working with Cymbal Retail, a separate, autonomous division of Cymbal with different staff, networking teams, and data center. Cymbal Direct and Cymbal Retail are not in the same Google Cloud organization. Cymbal Retail needs access to Cymbal Direct’s web application for making bulk orders, but the application will not be available on the public internet. You want to ensure that Cymbal Retail has access to your application with low latency. You also want to avoid egress network charges if possible. What should you do?

Verify that the subnet range Cymbal Retail is using doesn’t overlap with Cymbal Direct’s subnet range, and then enable VPC Network Peering for the project.Correct Answer

If Cymbal Retail does not have access to a Google Cloud data center, use Carrier Peering to connect the two networks.

Specify Cymbal Direct’s project as the Shared VPC host project, and then configure Cymbal Retail’s project as a service project.

Verify that the subnet Cymbal Retail is using has the same IP address range with Cymbal Direct’s subnet range, and then enable VPC Network Peering for the project.

QUESTION 6 OF 12

Cymbal Direct’s employees will use Google Workspace. Your current on-premises network cannot meet the requirements to connect to Google’s public infrastructure. What should you do?

Order a Dedicated Interconnect from a Google Cloud partner, and ensure that proper routes are configured.

Connect the network to a Google point of presence, and enable Direct Peering.

Order a Partner Interconnect from a Google Cloud partner, and ensure that proper routes are configured.

Connect the on-premises network to Google’s public infrastructure via a partner that supports Carrier Peering.Correct Answer

QUESTION 7 OF 12

Cymbal Direct is evaluating database options to store the analytics data from its experimental drone deliveries. You’re currently using a small cluster of MongoDB NoSQL database servers. You want to move to a managed NoSQL database service with consistent low latency that can scale throughput seamlessly and can handle the petabytes of data you expect after expanding to additional markets. What should you do?

Extract the data from MongoDB. Insert the data into Firestore using Datastore mode.

Create a Bigtable instance, extract the data from MongoDB, and insert the data into Bigtable.Correct Answer

Extract the data from MongoDB. Insert the data into Firestore using Native mode.

Extract the data from MongoDB, and insert the data into BigQuery.

QUESTION 8 OF 12

You are working with a client who is using Google Kubernetes Engine (GKE) to migrate applications from a virtual machine–based environment to a microservices-based architecture. Your client has a complex legacy application that stores a significant amount of data on the file system of its VM. You do not want to re-write the application to use an external service to store the file system data. What should you do?

In Cloud Shell, create a YAML file defining your Deployment called deployment.yaml. Create a Deployment in GKE by running the command kubectl apply -f deployment.yaml

In Cloud Shell, create a YAML file defining your Container called build.yaml. Create a Container in GKE by running the command gcloud builds submit –config build.yaml .

In Cloud Shell, create a YAML file defining your StatefulSet called statefulset.yaml. Create a StatefulSet in GKE by running the command kubectl apply -f statefulset.yamlCorrect Answer

In Cloud Shell, create a YAML file defining your Pod called pod.yaml. Create a Pod in GKE by running the command kubectl apply -f pod.yaml

QUESTION 9 OF 12

You are working in a mixed environment of VMs and Kubernetes. Some of your resources are on-premises, and some are in Google Cloud. Using containers as a part of your CI/CD pipeline has sped up releases significantly. You want to start migrating some of those VMs to containers so you can get similar benefits. You want to automate the migration process where possible. What should you do?

Manually create a GKE cluster, and then use Migrate for Anthos to set up the cluster, import VMs, and convert them to containers.Correct Answer

Use Migrate for Anthos to automate the creation of Compute Engine instances to import VMs and convert them to containers. (WRONG)

QUESTION 10 OF 12

Cymbal Direct has created a proof of concept for a social integration service that highlights images of its products from social media. The proof of concept is a monolithic application running on a single SuSE Linux virtual machine (VM). The current version requires increasing the VM’s CPU and RAM in order to scale. You would like to refactor the VM so that you can scale out instead of scaling up. What should you do?

Move the existing codebase and VM provisioning scripts to git, and attach external persistent volumes to the VMs.

Make sure that the application declares any dependent requirements in a requirements.txt or equivalent statement so that they can be referenced in a startup script. Specify the startup script in a managed instance group template, and use an autoscaling policy.
