Question No. 1

For compliance purposes, a cloud developer at an insurance company needs to save all customer policies for more than ten years. Which of the following options is the most cost-

efficient tier to save the data in the cloud?

Show Answer Hide Answer
Correct Answer: A

For compliance purposes, saving customer policies for more than ten years most cost-efficiently can be achieved by using the Archive storage tier. Archive or archival storage is designed for data that needs to be retained over the long term but accessed infrequently. It is generally the most cost-effective storage tier for this type of data.

Question No. 2

A cloud engineer is troubleshooting a connectivity issue. The application server with IP 192.168.1.10 in one subnet is not connecting to the MySQL database server with IP 192.168.2 20 in a different subnet. The cloud engineer reviews the following information:

Application Server Stateful Firewall

Which of the following should the cloud engineer address lo fix the communication issue?

Show Answer Hide Answer
Correct Answer: C

The connectivity issue between the application server and the MySQL database server in different subnets is likely due to the MySQL Server Stateful Firewall's inbound rules. The application server has an IP of 192.168.1.10, but the MySQL server's inbound rules only permit IP 192.168.1.10/32 on port 3306. This rule allows only a single IP address (192.168.1.10) to communicate on port 3306, which is typical for MySQL. However, if the application server's IP is not 192.168.1.10 or the application is trying to communicate on a different port, it would be blocked. To fix the communication issue, the cloud engineer should address the inbound rules on the MySQL Server Stateful Firewall to ensure that the application server's IP address and the required port are allowed. Reference: Based on the information provided in the question and general networking principles.


Question No. 3

Which of the following vulnerability management concepts is best defined as the process of discovering vulnerabilities?

Show Answer Hide Answer
Correct Answer: D

In vulnerability management, 'Identification' is the concept best defined as the process of discovering vulnerabilities. This step is crucial as it involves detecting vulnerabilities in systems, software, and networks, which is the first step in the vulnerability management process before moving on to assessment, remediation, and reporting.


Question No. 4

Which of the following are best practices when working with a source control system? (Select two).

Show Answer Hide Answer
Correct Answer: A, E

Best practices when working with a source control system include merging code often to ensure that changes from different team members are integrated regularly, reducing integration issues. Committing code often is also recommended to save small changes frequently, which helps in tracking changes and resolving issues more effectively. Reference: Source control system best practices are part of the software development and deployment guidelines discussed in the CompTIA Cloud+ examination objectives.


Question No. 5

A software engineer is integrating an application lo The cloud that is web socket based. Which of the following applications is the engineer most likely deploying?

Show Answer Hide Answer
Correct Answer: C

A chat application is most likely to be deployed when integrating a web socket-based application to the cloud. Web sockets provide full-duplex communication channels over a single, long-lived connection, which is ideal for real-time applications like chat services that require persistent connections between the client and server for instant data exchange. Reference: CompTIA Cloud+ materials cover cloud networking concepts, emphasizing the importance of choosing the right technologies, like web sockets, for specific application requirements to ensure efficient and responsive cloud-based services.
