An organization is deploying applications to the cloud using platform as a service.
In the shared responsibility model, what remains the responsibility of the customer organization?
- A . Physical security
- B . Network security
- C . Operations
- D . Data access policies
An organization wants to run their custom application in the cloud in a flexible and scalable way
without managing any infrastructure.
Which service model should they use?
- A . Infrastructure as a service
- B . Platform as a service
- C . Network as a service
- D . Software as a service
Your organization wants to run a container-based application on Google Cloud. This application is expected to increase in complexity. You have a security need for fine-grained control of traffic between the containers. You also have an operational need to exercise fine-grained control over the application’s scaling policies.
What Google Cloud product or feature should your organization use?
- A . Google Kubernetes Engine cluster
- B . App Engine
- C . Cloud Run
- D . Compute Engine virtual machines
A
Explanation:
Google Kubernetes Engine GKE seems a better fit since the requirement is for "security need for fine-grained control of traffic between the containers" and "fine-grained control over scaling policies". Such level of control is easier on GKE that Cloud Run.

What cloud deployment model is generally deployed between organizations such as non-profits, hospitals or even enterprises that share similar requirements or interests?
- A . Hybrid
- B . Community
- C . Private
- D . Public
B
Explanation:
Community Cloud C The cloud infrastructure is planned for selective use by a particular community of consumers from organizations that have mutual interests like security needs, policy, and compliance considerations.

An organization wants to migrate legacy applications currently hosted in their data center to the cloud. The current architecture dictates that each application needs its own operating system (OS) instead of sharing an OS.
Which infrastructure solution should they choose?
- A . Virtual machines
- B . Open source
- C . Serverless computing
- D . Containers
A
Explanation:
Virtual machines – you can install customized OS
Containers – about applications
Virtualization enables you to run multiple operating systems on the hardware of a single physical server, while containerization enables you to deploy multiple applications using the same operating system on a single virtual machine or server. Serverless computing would be no OS required and the open source operating system allows the use of code that is freely distributed and available to anyone and for commercial purposes such as Linux and Free BSD.
A company with its own private data center has called you in for help with their disaster recovery planning. News of multiple ransomware attacks has made them very anxious. They want to make they are well prepared for such an eventuality.
Which of these would be good recommendations?
- A . It is better to have redundancy; so, set up another private data center nearby so that you can quickly go over in case of an emergency.
- B . It is better to have redundancy; use one or many of the Google Cloud datacenters as a backup location.
- C . The one data center is enough, as long as the data is encrypted; attackers won’t be able to read the data.
- D . The one data center is enough as long as you regularly back up data and save it in another place in the same DC.
B
Explanation:
A single data center is vulnerable. So any option involving that is not good.

An organization wants to add a new function to their application. They want to write the code and let the public cloud provider handle the infrastructure.
Which infrastructure solution should they use?
- A . Virtual machines
- B . Bare Metal Solution
- C . Serverless computing
- D . Container Registry
C
Explanation:
Serverless computing, as public cloud prouder (eg. google) will mange the infra things
Your company’s development team is building an application that will be deployed on Cloud Run. You are designing a CI/CD pipeline so that any new version of the application can be deployed in the fewest number of steps possible using the CI/CD pipeline you are designing. You need to select a storage location for the images of the application after the CI part of your pipeline has built them.
What should you do?
- A . Create a Compute Engine image containing the application
- B . Store the images in Container Registry
- C . Store the images in Cloud Storage
- D . Create a Compute Engine disk containing the application
B
Explanation:

A large travel services company has been running all their workloads on Google Cloud in the previous year. They looked at their past usage of cloud resources and see that there is a consistent use of
10,000 virtual machines throughout the year. Based on the projections for the following year they have a strong indication that they will use at least this much or more capacity within Google Cloud.
What is one way in which they can take advantage of this knowledge?
- A . They can use these numbers to negotiate a better contract with another public cloud number.
- B . They can cut costs by cutting down on the number of VMs used.
- C . They can get into a committed use contract with Google Cloud to get a significant discount on the usage of VMs.
- D . They can ask for a sustained use discount.
C
Explanation:
Compute Engine lets you purchase committed use contracts in return for deeply discounted prices for VM usage. These discounts are referred to as committed use discounts. Committed use discounts are ideal for workloads with predictable resource needs. When you purchase a committed use contract, you purchase Compute Engine resources―such as vCPUs, memory, GPUs, local SSDs, and sole-tenant nodes―at a discounted price in return for committing to paying for those resources for 1 year or 3 years. The discount is up to 57% for most resources like machine types or GPUs. The discount is up to 70% for memory-optimized machine types.
An organization meets their service level objective (SLO) of 99 999% ("five nines")
How much downtime do their end users experience per year?
- A . 5 minutes
- B . 500 minutes
- C . 5 hours
- D . 5 days
