You created a cluster.YAML file containing

resources:

name: cluster

type: container.v1.cluster

properties:

zone: europe-west1-b

cluster:

description: My GCP ACE cluster

initialNodeCount: 2

You want to use Cloud Deployment Manager to create this cluster in GKE. What should you do?

gcloud deployment-manager deployments create my-gcp-ace-cluster --config cluster.yaml
gcloud deployment-manager deployments create my-gcp-ace-cluster --config cluster.yaml
gcloud deployment-manager deployments create my-gcp-ace-cluster --type container.v1.cluster --config cluster.yaml
gcloud deployment-manager deployments create my-gcp-ace-cluster --type container.v1.cluster --config cluster.yaml
gcloud deployment-manager deployments apply my-gcp-ace-cluster --type container.v1.cluster --config cluster.yaml
gcloud deployment-manager deployments apply my-gcp-ace-cluster --type container.v1.cluster --config cluster.yaml
gcloud deployment-manager deployments apply my-gcp-ace-cluster --config cluster.yaml
gcloud deployment-manager deployments apply my-gcp-ace-cluster --config cluster.yaml
Suggested answer: D

Explanation:

gcloud deployment-manager deployments create creates deployments based on the configuration file. (Infrastructure as code). All the configuration related to the artifacts is in the configuration file. This command correctly creates a cluster based on the provided cluster.yaml configuration file.

You created a Kubernetes deployment by running kubectl run nginx image=nginx labels=app=prod. Your Kubernetes cluster is also used by a number of other deployments. How can you find the identifier of the pods for this nginx deployment?

kubectl get deployments --output=pods
kubectl get deployments --output=pods
gcloud get pods --selector=''app=prod''
gcloud get pods --selector=''app=prod''
kubectl get pods -I ''app=prod''
kubectl get pods -I ''app=prod''
gcloud list gke-deployments -filter={pod }
gcloud list gke-deployments -filter={pod }
Suggested answer: C

Explanation:

This command correctly lists pods that have the label app=prod. When creating the deployment, we used the label app=prod so listing pods that have this label retrieve the pods belonging to nginx deployments. You can list pods by using Kubernetes CLI kubectl get pods.

You created a Kubernetes deployment by runningkubectl run nginx image=nginx replicas=1. After a few days, you decided you no longer want this deployment. You identified the pod and deleted it by running kubectl delete pod. You noticed the pod got recreated.

$ kubectl get pods

NAME READY STATUS RESTARTS AGE

nginx-84748895c4-nqqmt 1/1 Running 0 9m41s

$ kubectl delete pod nginx-84748895c4-nqqmt

pod nginx-84748895c4-nqqmt deleted

$ kubectl get pods

NAME READY STATUS RESTARTS AGE

nginx-84748895c4-k6bzl 1/1 Running 0 25s

What should you do to delete the deployment and avoid pod getting recreated?

kubectl delete deployment nginx
kubectl delete deployment nginx
kubectl delete --deployment=nginx
kubectl delete --deployment=nginx
kubectl delete pod nginx-84748895c4-k6bzl --no-restart 2
kubectl delete pod nginx-84748895c4-k6bzl --no-restart 2
kubectl delete inginx
kubectl delete inginx
Suggested answer: A

Explanation:

This command correctly deletes the deployment. Pods are managed by kubernetes workloads (deployments). When a pod is deleted, the deployment detects the pod is unavailable and brings up another pod to maintain the replica count. The only way to delete the workload is by deleting the deployment itself using the kubectl delete deployment command.

$ kubectl delete deployment nginx

deployment.apps nginx deleted

You have a number of applications that have bursty workloads and are heavily dependent on topics to decouple publishing systems from consuming systems. Your company would like to go serverless to enable developers to focus on writing code without worrying about infrastructure. Your solution architect has already identified Cloud Pub/Sub as a suitable alternative for decoupling systems. You have been asked to identify a suitable GCP Serverless service that is easy to use with Cloud Pub/Sub. You want the ability to scale down to zero when there is no traffic in order to minimize costs. You want to follow Google recommended practices. What should you suggest?

Cloud Run for Anthos
Cloud Run for Anthos

Cloud Run
App Engine Standard

Cloud Functions.
Cloud Functions.
Suggested answer: D

Explanation:

Cloud Functions is Google Cloud's event-driven serverless compute platform that lets you run your code locally or in the cloud without having to provision servers. Cloud Functions scales up or down, so you pay only for compute resources you use. Cloud Functions have excellent integration with Cloud Pub/Sub, lets you scale down to zero and is recommended by Google as the ideal serverless platform to use when dependent on Cloud Pub/Sub. 'If you're building a simple API (a small set of functions to be accessed via HTTP or Cloud Pub/Sub), we recommend using Cloud Functions.' Ref:https://cloud.google.com/serverless-options

You have been asked to migrate a docker application from datacenter to cloud. Your solution architect has suggested uploading docker images to GCR in one project and running an application in a GKE cluster in a separate project. You want to store images in the project img-278322 and run the application in the project prod-278986. You want to tag the image as acme_track_n_trace:v1. You want to follow Google-recommended practices. What should you do?

Run gcloud builds submit --tag gcr.io/img-278322/acme_track_n_trace
Run gcloud builds submit --tag gcr.io/img-278322/acme_track_n_trace

Run gcloud builds submit --tag gcr.io/prod-278986/acme_track_n_trace:v1
Suggested answer: B

Explanation:

Run gcloud builds submit tag gcr.io/img-278322/acme_track_n_trace:v1. is the right answer.

This command correctly tags the image as acme_track_n_trace:v1 and uploads the image to the img-278322 project.

Suggested answer: B

Explanation:

This command correctly specifies the duration that the signed url should be valid for by using the -d flag. The default is 1 hour so omitting the -d flag would have also resulted in the same outcome. Times may be specified with no suffix (default hours), or with s = seconds, m = minutes, h = hours, d = days. The max duration allowed is 7d.

Your managed instance group's health check is repeatedly failing, either to amisconfigured health check or misconfigured firewall rules not allowing the healthcheck to access the instance
Suggested answer: D

Explanation:

as the instances (normal or preemptible) would be terminated and relaunched if the health check fails either due to application not configured properly or the instances firewall do not allow health check to happen.

GCP provides health check systems that connect to virtual machine (VM) instances on a configurable, periodic basis. Each connection attempt is called a probe. GCP records the success or failure of each probe.

Health checks and load balancers work together. Based on a configurable number of sequential successful or failed probes, GCP computes an overall health state for each VM in the load balancer. VMs that respond successfully for the configured number of times are considered healthy. VMs that fail to respond successfully for a separate number of times are unhealthy.

GCP uses the overall health state of each VM to determine its eligibility for receiving new requests. In addition to being able to configure probe frequency and health state thresholds, you can configure the criteria that define a successful probe.
