Question 31

A development manager is building a new application. He asks you to review his requirements and identify what cloud technologies he can use to meet them. The application must: 1. Be based on open-source technology for cloud portability 2. Dynamically scale compute capacity based on demand 3. Support continuous software delivery 4. Run multiple segregated copies of the same application stack 5. Deploy application bundles using dynamic templates 6. Route network traffic to specific services based on URL Which combination of technologies will meet all of his requirements?

  1. Google Kubernetes Engine, Jenkins, and Helm
  2. Google Kubernetes Engine and Cloud Load Balancing
  3. Google Kubernetes Engine and Cloud Deployment Manager
  4. Google Kubernetes Engine, Jenkins, and Cloud Load Balancing

Question 32

You have created several pre-emptible Linux virtual machine instances using Google Compute Engine. You want to properly shut down your application before the virtual machines are preempted. What should you do?

  1. Create a shutdown script named k99.shutdown in the /etc/rc.6.d/ directory
  2. Create a shutdown script registered as a xinetd service in Linux and configure a Stackdriver endpoint check to call the service
  3. Create a shutdown script and use it as the value for a new metadata entry with the key shutdown-script in the Cloud Platform Console when you create the new virtual machine instance
  4. Create a shutdown script, registered as a xinetd service in Linux, and use the gcloud compute instances add-metadata command to specify the service URL as the value for a new metadata entry with the key shutdown-script-url

Question 33

Your organization has a 3-tier web application deployed in the same network on Google Cloud Platform. Each tier (web, API, and database) scales independently of the others. Network traffic should flow through the web to the API tier and then on to the database tier. Traffic should not flow between the web and the database tier. How should you configure the network?

  1. Add each tier to a different subnetwork
  2. Set up software based firewalls on individual VMs
  3. Add tags to each tier and set up routes to allow the desired traffic flow
  4. Add tags to each tier and set up firewall rules to allow the desired traffic flow

Question 34

Your development team has installed a new Linux kernel module on the batch servers in Google Compute Engine (GCE) virtual machines (VMs) to speed up the nightly batch process. Two days after the installation, 50% of the batch servers failed the nightly batch run. You want to collect details on the failure to pass back to the development team. Which three actions should you take? (Choose three.)

  1. Use Stackdriver Logging to search for the module log entries
  2. Read the debug GCE Activity log using the API or Cloud Console
  3. Use gcloud or Cloud Console to connect to the serial console and observe the logs
  4. Identify whether a live migration event of the failed server occurred, using in the activity log
  5. Adjust the Google Stackdriver timeline to match the failure time, and observe the batch server metrics
  6. Export a debug VM into an image, and run the image on a local server where kernel log messages will be displayed on the native screen

Question 35

Your company wants to try out the cloud with low risk. They want to archive approximately 100 TB of their log data to the cloud and test the analytics features available to them there, while also retaining that data as a long-term disaster recovery backup. Which two steps should you take? (Choose two.)

  1. Load logs into Google BigQuery
  2. Load logs into Google Cloud SQL
  3. Import logs into Google Stackdriver
  4. Insert logs into Google Cloud Bigtable
  5. Upload log files into Google Cloud Storage
