A software engineer at a cybersecurity company wants to access the cloud environment. Per company policy, the cloud environment should not be directly accessible via the internet.
Which of the following options best describes how the software engineer can access the cloud resources?
- A . SSH
- B . Bastion host
- C . Token-based access
- D . Web portal
B
Explanation:
A bastion host is the best option described for accessing cloud resources without direct internet access. It acts as a secure gateway to access internal networks from external sources and is often used in conjunction with other security measures such as SSH for secure connections.
Reference: The use of bastion hosts as a secure access point to cloud resources is a security best practice covered in the CompTIA Cloud+ certification’s domain on cloud security.
Which of the following do developers use to keep track of changes made during software development projects?
- A . Code drifting
- B . Code control
- C . Code testing
- D . Code versioning
D
Explanation:
Developers use code versioning to keep track of changes made during software development projects. It is a system that records changes to a file or set of files over time so that specific versions can be recalled later.

A project team that handles sensitive data analysis recently onboarded three new employees.
Which of the following should the PM do first?
- A . Check employee security clearance
- B . Allow access to the internet on corporate computers
- C . Train the new employees to handle sensitive data
- D . Execute an analysis of the sensitive data
A
Explanation:
When onboarding new staff who will handle sensitive data, the PM must first verify their security clearance or authorization. Only authorized personnel should access sensitive systems or datasets. Training follows after confirming clearance. Data analysis itself should never begin until security requirements are validated.

A SaaS provider introduced new software functionality for customers as part of quarterly production enhancements. After an update is implemented, users cannot locate certain transactions from an inbound integration. During the investigation, the application owner finds the following error in the logs:
Error: REST API – Deprecated call is no longer supported in this release.
Which of the following is the best action for the application owner to take to resolve the issue?
- A . Update the custom integration to use a supported function.
- B . Include the custom integration in the quarterly testing scope.
- C . Ask the users to monitor the quarterly updates.
- D . Revert the application to the last stable quarterly release.
A
Explanation:
The error message indicates that the SaaS provider has deprecated a function that was previously called by the custom integration. The best action for the application owner to take is to update the custom integration to use a function that is supported in the current release. This is a direct solution to the problem and ensures the custom integration conforms to the updated SaaS provider’s API.
Reference: Based on the error message provided and standard practices for dealing with deprecated API calls in a SaaS environment.
A log-parsing application requires significant processing power to ingest the logs streaming from web servers. The engineering team presents the cloud architect with four proposals using the same underlying hardware.
Which of the following should the cloud architect select in order to minimize the impact of an instance failure while keeping the cost as low as possible?
- A . Four instances of 4vCPU, 8GB RAM, 80GB SSD
- B . Four instances of 4vCPU, 8GB RAM, 80GB HDD
- C . Two instances of 8vCPU, 16GB RAM, 80GB SSD
- D . Two instances of 8vCPU, 16GB RAM, 80GB HDD
A
Explanation:
Choosing four instances with the given specifications would distribute the load and reduce the impact of any single instance failure. Using SSDs over HDDs would provide faster data processing capabilities which is crucial for a log-parsing application. This setup also retains cost efficiency by not over-provisioning resources.

A company needs to deploy its own code directly in the cloud without provisioning additional infrastructure.
Which of the following is the best cloud service model for the company to use?
- A . PaaS
- B . SaaS
- C . laaS
- D . XaaS
A
Explanation:
Platform as a Service (PaaS) is the best cloud service model for deploying code directly in the cloud without provisioning additional infrastructure. PaaS provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure.
Reference: The PaaS model and its benefits for application deployment are covered under the Cloud Concepts domain in the CompTIA Cloud+ certification.
Which of the following is an intended outcome of a stand-up meeting?
- A . To identify team members for next tasks
- B . To identify future tasks
- C . To identify stakeholders for next tasks
- D . To identify blocking tasks
D
Explanation:
Daily stand-ups focus on progress and impediments. Identifying blocking tasks helps the team resolve issues quickly to maintain productivity and keep operations flowing. This aligns with operational best practices in both agile and cloud environments.

A cloud administrator is working on the deployment of an e-commerce website. The administrator evaluates the scaling methods to be implemented when seasonal or flash sales are launched.
Which of the following scaling approaches should the administrator use to best manage this scenario?
- A . Scheduled
- B . Load
- C . Event
- D . Trending
