Demo Questions

Question 1
The application reliability team at your company this added a debug feature to their backend service to send all server events to Google Cloud Storage for eventual analysis. The event records are at least 50 KB and at most 15 MB and are expected to peak at 3,000 events per second. You want to minimize data loss.  
Which process should you implement? 
 
  1.   Append metadata to file body   Compress individual files 
      Name files with serverName – Timestamp 
      Create a new bucket if bucket is older than 1 hour and save individual files to the new bucket. Otherwise, save files to existing bucket. 
  2.   Batch every 10,000 events with a single manifest file for metadata   Compress event files and manifest file into a single archive file 
      Name files using serverName – EventSequence 
      Create a new bucket if bucket is older than 1 day and save the single archive file to the new bucket. Otherwise, save the single archive file to existing bucket. 
  3.   Compress individual files   Name files with serverName – EventSequence 
      Save files to one bucket 
      Set custom metadata headers for each object after saving 
  4.   Append metadata to file body   Compress individual files 
      Name files with a random prefix pattern 
      Save files to one bucket

Question 2
A recent audit revealed that a new network was created in your GCP project. In this network, a GCE instance has an SSH port open to the world. You want to discover this network’s origin.  
What should you do? 
 
  1. Search for Create VM entry in the Stackdriver alerting console 
  2. Navigate to the Activity page in the Home section. Set category to Data Access and search for Create VM entry 
  3. In the Logging section of the console, specify GCE Network as the logging section. Search for the Create Insert entry 
  4. Connect to the GCE instance using project SSH keys. Identify previous logins in system logs, and match these with the project owners list  
Correct answer: C
Explanation:
Incorrect Answers:  A: To use the Stackdriver alerting console we must first set up alerting policies. B: Data access logs only contain read-only operations. Audit logs help you determine who did what, where, and when. Cloud Audit Logging returns two types of logs: Admin activity logs Data access logs: Contains log entries for operations that perform read-only operations do not modify any data, such as get, list, and aggregated list methods.

Question 3
You want to make a copy of a production Linux virtual machine in the US-Central region. You want to manage and replace the copy easily if there are changes on the production virtual machine. You will deploy the copy as a new instance in a different project in the US-East region.  
What steps must you take? 
 
  1. Use the Linux dd and netcat commands to copy and stream the root disk contents to a new virtual machine instance in the US-East region. 
  2. Create a snapshot of the root disk and select the snapshot as the root disk when you create a new virtual machine instance in the US-East region. 
  3. Create an image file from the root disk with Linux dd command, create a new virtual machine instance in the US-East region 
  4. Create a snapshot of the root disk, create an image file in Google Cloud Storage from the snapshot, and create a new virtual machine instance in the US-East region using the image file the root disk.  
Correct answer: D
Question 4
Your company runs several databases on a single MySQL instance. They need to take backups of a specific database at regular intervals. The backup activity needs to complete as quickly as possible and cannot be allowed to impact disk performance.  
How should you configure the storage? 
 
  1. Configure a cron job to use the gcloud tool to take regular backups using persistent disk snapshots. 
  2. Mount a Local SSD volume as the backup location. After the backup is complete, use gsutil to move the backup to Google Cloud Storage. 
  3. Use gcsfise to mount a Google Cloud Storage bucket as a volume directly on the instance and write backups to the mounted location using mysqldump.  
  4. Mount additional persistent disk volumes onto each virtual machine (VM) instance in a RAID10 array and use LVM to create snapshots to send to Cloud Storage  
Correct answer: B
Question 5

Which three requirements should they include? (Choose three.) 
 
  1. Ensure that the load tests validate the performance of Cloud Bigtable 
  2. Create a separate Google Cloud project to use for the load-testing environment 
  3. Schedule the load-testing tool to regularly run against the production environment 
  4. Ensure all third-party systems your services use is capable of handling high load 
  5. Instrument the production services to record every transaction for replay by the load-testing tool 
  6. Instrument the load-testing tool and the target services with detailed logging and metrics collection  
Correct answer: ABF
Question 6
Your company places a high value on being responsive and meeting customer needs quickly. Their primary business objectives are release speed and agility. You want to reduce the chance of security errors being accidentally introduced.  
Which two actions can you take? (Choose two.) 
 
  1. Ensure every code check-in is peer reviewed by a security SME 
  2. Use source code security analyzers as part of the CI/CD pipeline  
  3. Ensure you have stubs to unit test all interfaces between components 
  4. Enable code signing and a trusted binary repository integrated with your CI/CD pipeline 
  5. Run a vulnerability security scanner as part of your continuous-integration /continuous-delivery (CI/CD) pipeline  
Correct answer: DE
Question 7
You want to enable your running Google Kubernetes Engine cluster to scale as demand for your application changes.  
What should you do? 
 
  1. Add additional nodes to your Kubernetes Engine cluster using the following command: gcloud container clusters resize 
    CLUSTER_Name – -size 10 
  2. Add a tag to the instances in the cluster with the following command: gcloud compute instances add-tags 
    INSTANCE - -tags enable- 
    autoscaling max-nodes-10 
  3. Update the existing Kubernetes Engine cluster with the following command: gcloud alpha container clusters 
    update mycluster - -enable- 
    autoscaling - -min-nodes=1 - -max-nodes=10 
  4. Create a new Kubernetes Engine cluster with the following command: gcloud alpha container clusters 
    create mycluster - -enable- 
    autoscaling - -min-nodes=1 - -max-nodes=10 
    and redeploy your application

Question 9
Your company just finished a rapid lift and shift to Google Compute Engine for your compute needs. You have another 9 months to design and deploy a more cloud-native solution. Specifically, you want a system that is no-ops and auto-scaling.  
Which two compute products should you choose? (Choose two.) 
 
  1. Compute Engine with containers 
  2. Google Kubernetes Engine with containers 
  3. Google App Engine Standard Environment  
  4. Compute Engine with custom instance types 
  5. Compute Engine with managed instance groups  
Correct answer: BC
Explanation:
B: With Container Engine, Google will automatically deploy your cluster for you, update, patch, secure the nodes. Kubernetes Engine's cluster autoscaler automatically resizes clusters based on the demands of the workloads you want to run. C: Solutions like Datastore, BigQuery, AppEngine, etc are truly NoOps. App Engine by default scales the number of instances running up and down to match the load, thus providing consistent performance for your app at all times while minimizing idle instances and thus reducing cost. Note: At a high level, NoOps means that there is no infrastructure to build out and manage during usage of the platform. Typically, the compromise you make with NoOps is that you lose control of the underlying infrastructure.  Reference: https://www.quora.com/How-well-does-Google-Container-Engine-support-Google-Cloud-Platform%E2%80%99s-NoOps-claim
