NEW QUESTION 25
Which of the following is / are true for Preemptible Instances.

• A. Preemptible instances can't live migrate to a regular VM instance, or be set to au-tomatically restart when there is a maintenance event.
• B. Google Cloud Free Tier credits for compute engine do not apply to preemptible in-stances.
• C. All of the above.
• D. Preemptible Instances have no Service Level Agreement (Compute Engine SLA).

Answer: C

Explanation:
Preemptible instances function like normal instances but have the following limitations:
-> Compute Engine might stop preemptible instances at any time due to system events. The probability that Compute Engine will stop a preemptible instance for a system event is generally low, but might vary from day to day and from zone to zone depending on current conditions.
-> Compute Engine always stops preemptible instances after they run for 24 hours. Certain actions reset this 24-hour counter.
-> Preemptible instances are finite Compute Engine resources, so they might not always be available.
-> Preemptible instances can't live migrate to a regular VM instance, or be set to automatically restart when there is a maintenance event.
-> Due to the above limitations, preemptible instances are not covered by any Service Level Agreement (and, for clarity, are excluded from the Compute Engine SLA).
-> The Google Cloud Free Tier credits for Compute Engine do not apply to preemptible instances.

NEW QUESTION 31
Your company has a requirement to run manual tests on their web products for UX research before it is released to end customers. The people who will do the tests are external to the company. They will either use their own Gmail id or be given temporary email ids using the applications and record-ing their inputs in another app. The UX testing is done in the last week of the month. Each month the UX testers could be different. How should the IT team manage the users?

• A. Since the app is anyways going to be public, create permanent credentials for the UX testers that they can conveniently use each time.
• B. It would be a security issue to have users come and go. Recommend that the test-ers be permanently hired to plug the vulnerability issue.
• C. It would be a security issue to have users come and go. Recommend that the test-ers be permanently hired to plug the vulnerability issue.
• D. Create a Group with the permissions required to do the test and record their in-puts. When users arrive each week, add them to the group and after the testing period, remove them from the group.

Answer: D

Explanation:
Groups are convenient to use for this requirement. Permissions to the group are automatically inherited by the members of the group. Adding and removing UX testers from the group will grant and remove permissions.

"With cloud messaging you can Customize and deliver messages accordingly to the predetermined time in the user's local time zone." Comment on the above statement.

• A. The above statement is partially true.
• B. The above statement is completely true.
• C. This statement is undefined.
• D. The above statement is completely false.

Answer: B

Explanation:
Firebase Cloud Messaging:
Firebase Cloud Messaging (FCM) is a cross-platform messaging solution that lets you reliably send messages at no cost.
Using FCM, you can notify a client app that new email or other data is available to sync. You can send notification messages to drive user re-engagement and retention. For use cases such as instant messaging, a message can transfer a payload of up to 4000 bytes to a client app.
Key capabilities of Firebase Cloud Messaging:
Send notification messages or data messages: Send notification messages that are displayed to your user. Or send data messages and determine completely what happens in your application code.
Versatile message targeting: Distribute messages to your client app in any of 3 ways-to single devices, to groups of devices, or to devices subscribed to topics.
Send messages from client apps: Send acknowledgments, chats, and other messages from devices back to your server over FCM's reliable and battery-efficient connection channel.

 

NEW QUESTION 35
In terms of Dockers and Kubernetes, which of the following statements are correct?

• A. Kubernetes can be used with or without Docker.
• B. Difference between Docker and Kubernetes relates to the role each play in con-tainerizing and running your applications
• C. All of the above.
• D. Kubernetes uses Docker to deploy, manage, and scale containerized applications.

Answer: C

Explanation:
Kubernetes vs. Docker
Often misunderstood as a choice between one or the other, Kubernetes and Docker are different yet complementary technologies for running containerized applications.
Docker lets you put everything you need to run your application into a box that can be stored and opened when and where it is required. Once you start boxing up your applications, you need a way to manage them; and that's what Kubernetes does.
Kubernetes is a Greek word meaning 'captain' in English. Like the captain is responsible for the safe journey of the ship in the seas, Kubernetes is responsible for carrying and delivering those boxes safely to locations where they can be used.
- Kubernetes can be used with or without Docker.
- Docker is not an alternative to Kubernetes, so it's less of a "Kubernetes vs. Docker" question. It's about using Kubernetes with Docker to containerize your applications and run them at scale.
- The difference between Docker and Kubernetes relates to the role each play in containerizing and running your applications.
- Docker is an open industry standard for packaging and distributing applications in containers.
- Kubernetes uses Docker to deploy, manage, and scale containerized applications.

NEW QUESTION 37
Your organization wants to optimize its use of Google Cloud's discounts on virtual machine-based workloads. You plan to use 200 CPUs constantly for the next 3 years, and you forecast that spikes of up to 300 CPUs will occur approximately 30% of the time. What should you choose?

• A. 1-year committed use discount for 200 CPUs
• B. Regular pay-as-you-go pricing
• C. 3-year committed use discount for 300 CPUs
• D. 3-year committed use discount for 200 CPUs

Answer: D

Explanation:
you can get a 57% discount by agreeing to commit to a 3-year contract. Any usage over the commitment will just be billed at the standard rate. Since they only need 300 CPUs 30% of the time, will pick answer C so that we are not paying usage off 300 CPUs all of the time. This gives us a discount of 57% for 200 CPU's, huge cost savings.

 

NEW QUESTION 38

NEW QUESTION 39
A partner of yours used to have their own private data center. Your company was already on Google Cloud and now they have also moved to Google Cloud. You are investigating whether there are ways to collaborate better or shared services. What would be one good option to consider?

• A. Use public IP addresses as before. It will automatically be routed internally only.
• B. Use VPC Peering to share resources privately between your two organizations.
• C. Use VPC Shared Networks to share common resources.
• D. Use Private Service Access within Google Cloud.

Answer: B

Explanation:
VPC Network Peering allows internal IP address connectivity across two Virtual Private Cloud (VPC) networks regardless of whether they belong to the same project or the same organization.
-> Shared VPC is only within an organization - it allows an organization to connect resources from multiple projects to a common Virtual Private Cloud (VPC) network, so that they can communicate with each other securely and efficiently using internal IPs from that network.
-> Private Google Access is only to access Google APIs and services
