Question 216

An organization has been using an old version of an Apache Log4j software component in its critical software application. Which of the following should the organization use to calculate the severity of the risk from using this component?

A.CWE
B.CVSS
C.CWSS
D.CVE

Correct Answer: B

The Common Vulnerability Scoring System (CVSS) is what the organization should use to calculate the severity of the risk from using an old version of Apache Log4j software component. CVSS provides an open framework for communicating the characteristics and impacts of IT vulnerabilities. References: CompTIA Cloud+ Study Guide (Exam CV0-004) - Chapter on Risk Management

Question 217

Which of the following strategies requires the development of new code before an application can be successfully migrated to a cloud provider?

A.Refactor
B.Rearchitect
C.Rehost
D.Replatform

Correct Answer: A

Refactoring requires the development of new code before an application can be successfully migrated to a cloud provider. It often involves restructuring and optimizing the existing code without changing its external behavior to fit into the new cloud environment.References: Application migration strategies and the requirements for each, like refactoring, are included in cloud migration best practices covered in CompTIA Cloud+.

Question 218

A cloud engineer must find the root cause of a recent performance issue. Logs and metrics have been collected and are available. Which of the following is the best way to determine the source of the issue?

A.Aggregating logs
B.Enabling tracing
C.Performing code review
D.Enabling verbose logging

Correct Answer: B

In Cloud+ (CV0-004) troubleshooting and observability objectives, logs and metrics provide valuable signals, but they often don't show where time is spent across a distributed request path. When an application spans microservices, APIs, queues, and databases, metrics can indicate symptoms (high latency, CPU, error rate) and logs can show events, yet correlating them end-to-end can still leave uncertainty about the true bottleneck. Tracing adds the missing "third pillar" of observability by following a single transaction through each component and measuring per-hop latency, dependencies, and call sequences. This makes it the best method for pinpointing the source of performance degradation (for example, a slow database call, an overloaded downstream service, or excessive retries). Aggregating logs is helpful for central visibility, but it doesn't inherently provide request-level timing across services. Verbose logging increases overhead and noise and is typically used after narrowing scope. Code review is slower and not the first step when operational telemetry can directly isolate the bottleneck.

Question 219

Five thousand employees always access the company's public cloud-hosted web application on a daily basis during the same time frame. Some users have been reporting performance issues while attempting to connect to the web application Which of the following is the best configuration approach to resolve this issue?

A.Scale vertically based on a trend.
B.Scale horizontally based on a schedule
C.Scale vertically based on a load.
D.Scale horizontally based on an event

Correct Answer: B

Scaling horizontally means adding more instances of the application or servers to handle increased traffic, rather than increasing the resources (CPU, memory) of a single server (which would be vertical scaling). Since the performance issues occur during a specific, predictable time frame every day, scaling horizontally based on a schedule would ensure that additional resources are available when needed, improving performance without waiting for a load threshold to be reached.

Question 220

A small nonprofit wants a cheap and simple way to automate some of its workflows that connect different services together in the cloud. Which of the following options best fulfills this need?

A.Using a managed service provider
B.Leveraging an integration platform as a service
C.Automating workflows with Python and deploying in a VM
D.Implementing a message broker to access the APIs

Correct Answer: B

An integration platform as a service (iPaaS) is specifically designed to connect cloud services and automate workflows with minimal infrastructure management and development effort. It provides a cost-effective and simple way for organizations to integrate applications and automate business processes through prebuilt connectors and low-code tools.
