質問 # 211
You're negotiating SLAs with a customer. You have communicated that there will be a 99.99% (four 9s) availability for the service you are providing. Every aspect of the service is under your con-trol. They want to modify the reliability to 99.999% (five 9s). What do you tell them? (Choose two answer)
- A. Yes, that could be possible. If yes, there will be a significantly higher charge be-cause the effort is significantly higher too.
- B. Ask them for the reasonable downtime they are willing to absorb. If it is more than 60 minutes in an entire year, explain how the current SLA meets that requirement.
- C. Yes, that is possible. There is hardly any difference to provide another 0.009% availability.
- D. Yes, that is possible, but there will be an additional charge of 9% for the service because that is the additional effort required.
正解：A、B
解説：
Explanation
In many cases, customers might not know the implications of the 9s with respect to scheduled maintenance, upgrades, etc. It's possible that they are holding unnecessary expectations that significantly exceed their requirements.
-> Even though 0.0009 % increase it looks like a small increment, an addition of a single 9 reduces the possible downtime by 10 times. So the effort is often much greater.

質問 # 215
You are working with a user to set up an application in a new VPC behind a firewall and it is no-ticed that the user is concerned about data egress. Therefore, to provide assistance you want to con-figure the fewest open egress ports. Which of the following statement is correct?
- A. Set up a low-priority (65534) rule that blocks all egress and a high-priority rule (1000) that allows only the appropriate ports.
- B. Set up a high-priority (1000) rule to allow the appropriate ports.
- C. Set up a high-priority (1000) rule that pairs both ingress and egress ports.
- D. Set up a high-priority (1000) rule that blocks all egress and a low-priority (65534) rule that allows only the appropriate ports.
正解：A
解説：
Implied rules Every VPC network has two implied firewall rules. These rules exist, but are not shown in the Cloud Console:
Implied allow egress rule. An egress rule whose action is allow, destination is 0.0.0.0/0, and priority is the lowest possible (65535) lets any instance send traffic to any destination, except for traffic blocked by Google Cloud. A higher priority firewall rule may restrict outbound access. Internet access is allowed if no other firewall rules deny outbound traffic and if the instance has an external IP address or uses a Cloud NAT instance. For more information, see Internet access requirements.

Results will be stored in a global Cloud Storage bucket. The compute resources are not bound to any single geographical location. This software needs to run on Google Cloud in a cost-optimized way.
What should you do?
- A. Deploy the application on Compute Engine using preemptible instances
- B. Start more instances with fewer virtual centralized processing units (vCPUs) instead of fewer instances with more vCPUs
- C. Develop the application so it can run in an unmanaged instance group
- D. Create a reservation for the minimum number of Compute Engine instances you will use

質問 # 217
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. Software as a service
- D. Network as a service
正解：B
解説：
The correct answer is B. Platform as a service. Here's why:
Context of the Questio n : The organization wants to run a custom application in the cloud in a flexible and scalable way without managing any infrastructure.
Google Cloud Product Relevance:
Platform as a Service (PaaS) provides a platform that allows customers to develop, run, and manage applications without dealing with the complexity of building and maintaining the underlying infrastructure.
Google Cloud's App Engine is an example of a PaaS offering. It enables organizations to deploy custom applications in a fully managed environment where scaling, load balancing, and infrastructure management are handled automatically.
Why Not Other Options:
A . Infrastructure as a service: IaaS requires the organization to manage the underlying infrastructure (like virtual machines, networks, and storage), which is not suitable if the organization does not want to manage any infrastructure.
C . Network as a service: NaaS is focused on network connectivity and does not provide the capabilities needed to run custom applications.
D . Software as a service: SaaS provides pre-built applications managed by a provider; it is not suitable for running custom applications.
Google Cloud Digital Leader Reference:
For more on PaaS, refer to the Google App Engine documentation.

質問 # 226
When is data automatically encrypted in Google Cloud?
- A. When it is in transit only.
- B. When it is at rest only.
- C. When it is at rest and in transit.
- D. Data is not automatically encrypted by default.
正解：C
解説：
The correct answer is B. When it is at rest and in transit. Here's why:
Context of the Questio n : The question is about when data is automatically encrypted by Google Cloud.
Google Cloud Product Relevance:
Google Cloud automatically encrypts data at rest and in transit. This means that data stored in Google Cloud (such as in Google Cloud Storage or BigQuery) is encrypted by default to protect it from unauthorized access. Similarly, data in transit between Google Cloud services or between users and Google Cloud is encrypted using TLS (Transport Layer Security).
These automatic encryption measures are part of Google's comprehensive approach to data security, ensuring that data remains protected throughout its lifecycle.
Why Not Other Options:
A . When it is at rest only: This is incorrect because data is also encrypted in transit.
C . When it is in transit only: This is incorrect because data is also encrypted at rest.
D . Data is not automatically encrypted by default: This is incorrect as Google Cloud provides automatic encryption for data both at rest and in transit.
Google Cloud Digital Leader Reference:
Refer to Google Cloud Encryption documentation for more information on how data is encrypted in Google Cloud.
