Question 316

A systems administrator is reviewing the application development process with the development team and notices that the team has no way to collaboratively develop code. Which of the following methods should be implemented to resolve this issue?

Correct Answer: B
Detailed Explanation:
* B. Version control: Version control systems like Git enable collaborative development, allowing team members to track changes, merge contributions, and resolve conflicts efficiently.
References:
* CompTIA Cloud+ CV0-003 Study Guide Chapter 4: Solution Design in Support of Business Requirements.

Question 317

A cloud administrator needs to verify domain ownership with a third party. The third party has provided a secret that must be added to the DNS server. Which of the following DNS records does the administrator need to update to include the secret?

Correct Answer: B
TXT is a type of DNS record that can store arbitrary text data, such as a secret, a verification code, or a configuration parameter. TXT records are often used to verify domain ownership with a third party, such as a certificate authority, an email service provider, or a cloud service provider. The third party can check the TXT record of the domain and compare it with the secret they provided to confirm the identity and authority of the domain owner .

Question 318

A systems administrator is diagnosing performance issues on a web application. The web application sends thousands of extremely complex SQL queries to a database server, which has trouble retrieving the information in time. The administrator checks the database server and notes the following resource utilization:
CPU: 64%
RAM: 97%
Network throughput: 384,100Kbps.
Disk throughput: 382,700Kbps
The administrator also looks at the storage for the database server and notices it is consistently near its OPS limit. Which of the following will BEST resolve these performance issues?

Correct Answer: B
The performance issue is caused by the high demand of complex SQL queries on the database server, which consumes a lot of RAM and disk throughput. Increasing caching on the database server would reduce the number of disk reads and writes, as well as improve the response time of the queries by storing frequently accessed data in memory. This would be the best solution to resolve the performance issue. Reference: CompTIA Cloud+ Certification Exam Objectives, Domain 4.0 Troubleshooting, Objective 4.3 Given a scenario, troubleshoot capacity issues within a cloud environment.

Question 319

A cloud administrator needs to implement a new system within the current CSR The system requires a storage service to allocate a large number of digital files and images. The storage service must keep files for distributed access and serve images directly to the user's browser. Which of the following solutions would best meet these requirements?

Correct Answer: B
Explanation
One possible solution for the cloud administrator is to use object storage. Object storage is a type of cloud storage service that stores data as objects, which consist of data, metadata, and a unique identifier. Object storage can allocate a large number of digital files and images, as it can scale to petabytes of capacity and handle billions of objects. Object storage can also keep files for distributed access, as it can store data across multiple regions and zones, and provide high availability and durability. Object storage can also serve images directly to the user's browser, as it can generate public URLs for each object that can be accessed over the internet12.
NAS storage, file storage, and block storage are not the best solutions for these requirements, as they have some limitations compared to object storage. NAS storage and file storage store data as files in a hierarchical structure, which can be inefficient for managing a large number of files and images. Block storage stores data as blocks in a fixed structure, which can be wasteful for storing variable-sized files and images. NAS storage, file storage, and block storage also require a file system or a protocol to access the data, which can add complexity and overhead to the system12.

Question 320

A security team is conducting an audit of the security group configurations for the Linux servers that are hosted in a public laaS. The team identifies the following rule as a potential

A cloud administrator, who is working remotely, logs in to the cloud management console and modifies the rule to set the source to "My IR" Shortly after deploying the rule, an internal developer receives the following error message when attempting to log in to the server using SSH: Network error: connection timed out. However, the administrator is able to connect successfully to the same server using SSH. Which of the following is the BEST option for both the developer and the administrator to access the server from their locations?

Correct Answer: C
The inbound rule that the security team identified as a potential vulnerability is the one that allows SSH access (port 22) from any source (0.0.0.0/0). This means that anyone on the internet can try to connect to the Linux servers using SSH, which poses a risk of unauthorized access or brute-force attacks. The cloud administrator, who is working remotely, logs in to the cloud management console and modifies the rule to set the source to "My IP". This means that only the administrator's IP address can connect to the Linux servers using SSH, which improves the security of the servers. However, this also prevents other authorized users, such as the internal developer, from accessing the servers using SSH, as they have different IP addresses than the administrator. Therefore, the administrator needs to modify the rule again to allow more sources for SSH access.
The best option for both the developer and the administrator to access the server from their locations is to modify the inbound rule to allow the company's external IP address as a source. This means that only the IP addresses that belong to the company's network can connect to the Linux servers using SSH, which reduces the attack surface and ensures that only authorized users can access the servers. The company's external IP address can be obtained by using a web service such as [What Is My IP Address?] or [IP Location]. The administrator can then enter this IP address or its CIDR notation in the source field of the inbound rule.
