Google Cloud Certified - Professional Cloud DevOps Engineer Exam Sample Questions (Q145-Q150):

NEW QUESTION # 145
Your company follows Site Reliability Engineering principles. You are writing a postmortem for an incident, triggered by a software change, that severely affected users. You want to prevent severe incidents from happening in the future. What should you do?

Answer: C


NEW QUESTION # 146
Your organization wants to increase the availability target of an application from 99 9% to 99 99% for an investment of $2 000 The application's current revenue is S1,000,000 You need to determine whether the increase in availability is worth the investment for a single year of usage What should you do?

Answer: C

Explanation:
Explanation
The best option for determining whether the increase in availability is worth the investment for a single year of usage is to calculate the value of improved availability to be $900, and determine that the increase in availability is not worth the investment. To calculate the value of improved availability, we can use the following formula:
Value of improved availability = Revenue * (New availability - Current availability) Plugging in the given numbers, we get:
Value of improved availability = $1,000,000 * (0.9999 - 0.999) = $900
Since the value of improved availability is less than the investment of $2,000, we can conclude that the increase in availability is not worth the investment.


NEW QUESTION # 147
You built a serverless application by using Cloud Run and deployed the application to your production environment You want to identify the resource utilization of the application for cost optimization What should you do?

Answer: C


NEW QUESTION # 148
Your company is creating a new cloud-native Google Cloud organization. You expect this Google Cloud organization to first be used by a small number of departments and then expand to be used by a large number of departments. Each department has a large number of applications varying in size. You need to design the VPC network architecture. Your solution must minimize the amount of management required while remaining flexible enough for development teams to quickly adapt to their evolving needs. What should you do?

Answer: C

Explanation:
Comprehensive and Detailed Explanation:
The best network architecture should balance scalability, flexibility, and low management overhead. The best approach is:
Use a separate VPC for each department # This provides clear isolation for each team while allowing flexibility.
Use VPC Network Peering # VPC Peering enables private communication between VPCs with low latency and no bandwidth bottlenecks.
#Why not other options?
B (Private Service Connect for VPC connections)## Not designed for inter-VPC networking; it's meant for connecting to Google services or external services securely.
C (Separate VPC per application)## Too many VPCs would lead to complex management overhead.
D (Cloud VPN for connectivity)## Cloud VPN is for hybrid networking, not the best choice for internal GCP VPC connectivity.

NEW QUESTION # 149
You need to create a Cloud Monitoring SLO for a service that will be published soon. You want to verify that requests to the service will be addressed in fewer than 300 ms at least 90% Of the time per calendar month. You need to identify the metric and evaluation method to use. What should you do?

Answer: B

Explanation:
The correct answer is
A, Select a latency metric for a request-based method of evaluation.
A latency metric measures how responsive your service is to users. For example, you can use the cloud.googleapis.com/http/server/response_latencies metric to measure the latency of HTTP requests to your service1. A request-based method of evaluation counts the number of successful requests that meet a certain criterion, such as being below a latency threshold, and compares it to the number of all requests. For example, you can define an SLI as the ratio of requests with latency below 300 ms to all requests2. A request-based method of evaluation is suitable for measuring performance over time, such as per calendar month. You can set an SLO for the SLI to be at least 90%, which means that you expect 90% of the requests to have latency below 300 ms in a month3.
