Demo Questions
Question 1
The operations manager asks you for a list of recommended practices that she should consider when migrating a J2EE application to the cloud.
Which three practices should you recommend? (Choose three.)
- Port the application code to run on Google App Engine
- Integrate Cloud Dataflow into the application to capture real-time metrics
- Instrument the application with a monitoring tool like Stackdriver Debugger
- Select an automation framework to reliably provision the cloud infrastructure
- Deploy a continuous integration tool with automated testing in a staging environment
- Migrate from MySQL to a managed NoSQL database like Google Cloud Datastore or Bigtable
Correct answer: CDE
Question 2
A news feed web service has the following code running on Google App Engine. During peak load, users report that they can see news articles they already viewed.
What is the most likely cause of this problem?
- The session variable is local to just a single instance Most Voted
- The session variable is being overwritten in Cloud Datastore
- The URL of the API needs to be modified to prevent caching
- The HTTP Expires header needs to be set to -1 stop caching
Correct answer: A
Question 3
An application development team believes their current logging tool will not meet their needs for their new cloud-based product. They want a better tool to capture errors and help them analyze their historical log data. You want to help them find a solution that meets their needs.
What should you do?
- Direct them to download and install the Google StackDriver logging agent
- Send them a list of online resources about logging best practices
- Help them define their requirements and assess viable logging tools
- Help them upgrade their current tool to take advantage of any new features
Correct answer: C
Question 4
To reduce costs, the Director of Engineering has required all developers to move their development infrastructure resources from on-premises virtual machines (VMs) to Google Cloud Platform. These resources go through multiple start/stop events during the day and require state to persist. You have been asked to design the process of running a development environment in Google Cloud while providing cost visibility to the finance department.
Which two steps should you take? (Choose two.)
- Use the - -no-auto-delete flag on all persistent disks and stop the VM Most Voted
- Use the - -auto-delete flag on all persistent disks and terminate the VM
- Apply VM CPU utilization label and include it in the BigQuery billing export
- Use Google BigQuery billing export and labels to associate cost to groups Most Voted
- Store all state into local SSD, snapshot the persistent disks, and terminate the VM
- Store all state in Google Cloud Storage, snapshot the persistent disks, and terminate the VM
Correct answer: AD
Question 5
Your company wants to track whether someone is present in a meeting room reserved for a scheduled meeting. There are 1000 meeting rooms across 5 offices on 3 continents. Each room is equipped with a motion sensor that reports its status every second. The data from the motion detector includes only a sensor ID and several different discrete items of information. Analysts will use this data, together with information about account owners and office locations.
Which database type should you use?
- Flat file
- NoSQL Most Voted
- Relational
- Blobstore
Correct answer: B
Question 6
You set up an autoscaling instance group to serve web traffic for an upcoming launch. After configuring the instance group as a backend service to an HTTP(S) load balancer, you notice that virtual machine (VM) instances are being terminated and re-launched every minute.
The instances do not have a public IP address.
You have verified the appropriate web response is coming from each instance using the curl command. You want to ensure the backend is configured correctly.
What should you do?
- Ensure that a firewall rules exists to allow source traffic on HTTP/HTTPS to reach the load balancer.
- Assign a public IP to each instance and configure a firewall rule to allow the load balancer to reach the instance public IP.
- Ensure that a firewall rule exists to allow load balancer health checks to reach the instances in the instance group. Most Voted
- Create a tag on each instance with the name of the load balancer. Configure a firewall rule with the name of the load balancer as the source and the instance tag as the destination.
Correct answer: C
Question 7
You write a Python script to connect to Google BigQuery from a Google Compute Engine virtual machine. The script is printing errors that it cannot connect to BigQuery.
What should you do to fix the script?
- Install the latest BigQuery API client library for Python
- Run your script on a new virtual machine with the BigQuery access scope enabled
- Create a new service account with BigQuery access and execute your script with that user
- Install the bq component for gcloud with the command gcloud components install bq.
Correct answer: C
Question 8
Your company has successfully migrated to the cloud and wants to analyze their data stream to optimize operations. They do not have any existing code for this analysis, so they are exploring all their options. These options include a mix of batch and stream processing, as they are running some hourly jobs and live- processing some data as it comes in.
Which technology should they use for this?
- Google Cloud Dataproc
- Google Cloud Dataflow Most Voted
- Google Container Engine with Bigtable
- Google Compute Engine with Google BigQuery
Correct answer: B
Question 9
Your company's user-feedback portal comprises a standard LAMP stack replicated across two zones. It is deployed in the us-central1 region and uses autoscaled managed instance groups on all layers, except the database. Currently, only a small group of select customers have access to the portal. The portal meets a 99,99% availability SLA under these conditions. However next quarter, your company will be making the portal available to all users, including unauthenticated users. You need to develop a resiliency testing strategy to ensure the system maintains the SLA once they introduce additional user load.
What should you do?
- Capture existing users input, and replay captured user load until autoscale is triggered on all layers. At the same time, terminate all resources in one of the zones
- Create synthetic random user input, replay synthetic load until autoscale logic is triggered on at least one layer, and introduce ג€chaosג€ to the system by terminating random resources on both zones
- Expose the new system to a larger group of users, and increase group size each day until autoscale logic is triggered on all layers. At the same time, terminate random resources on both zones
- Capture existing users input, and replay captured user load until resource utilization crosses 80%. Also, derive estimated number of users based on existing user's usage of the app, and deploy enough resources to handle 200% of expected load
Correct answer: B
Question 10
Your solution is producing performance bugs in production that you did not see in staging and test environments. You want to adjust your test and deployment procedures to avoid this problem in the future.
What should you do?
- Deploy fewer changes to production
- Deploy smaller changes to production
- Increase the load on your test and staging environments
- Deploy changes to a small subset of users before rolling out to production
Correct answer: C
