Question 13

An organization needs to retain its data for compliance reasons but only when required. Which of the following would be the most cost-effective type of tiered storage?

A. Warm

B. Hot

C. Archive

D. Cold

Correct Answer:C
Archive storage is the most cost-effective type of tiered storage for retaining data that is infrequently accessed and only when required for compliance reasons. It is designed for long-term storage and offers lower storage costs compared to hot, cold, or warm storage tiers.References: Understanding data storage and the various tiers, including archival storage, is part of cloud storage strategies covered in the CompTIA Cloud+ certification.

Question 14

A company is developing a new web application that requires a relational database management system with minimal operational overhead. Which of the following should the company choose?

A. A database installed on a virtual machine

B. A managed SQL database on the cloud

C. A database migration service

D. A hybrid database setup

Correct Answer:B
For a new web application that requires a relational database management system with minimal operational overhead, the company should choose a managed SQL database on the cloud. Managed databases provide automated backups, patching, and other management tasks, reducing the administrative burden.References: The use of managed services, like managed databases, to minimize operational overhead is a strategic decision in cloud computing covered in CompTIA Cloud+.

Question 15

Users report being unable to access an application that uses TLS 1.1. The users are able to access other applications on the internet. Which of the following is the most likely reason for this issue?

A. The security team modified user permissions.

B. Changes were made on the web server to address vulnerabilities.

C. Privileged access was implemented.

D. The firewall was modified.

Correct Answer:B
If users are unable to access an application that uses TLS 1.1 but can access other internet applications, it is likely that changes were made on the web server to address vulnerabilities, such as disabling outdated and less secure protocols like TLS 1.1.

Question 16

Which of the following describes the main difference between public and private container repositories?

A. Private container repository access requires authorization, while public repository access does not require authorization.

B. Private container repositories are hidden by default and containers must be directly referenced, while public container repositories allow browsing of container images.

C. Private container repositories must use proprietary licenses, while public container repositories must have open-source licenses.

D. Private container repositories are used to obfuscate the content of the Dockerfile, while public container repositories allow for Dockerfile inspection.

Correct Answer:A
The main difference between public and private container repositories lies in access control. Public repositories allow users to download and use container images without requiring any authorization, making them accessible to anyone. On the other hand, private repositories require users to have proper authorization, usually through credentials, to access the container images, thus providing a level of privacy and security control.

Question 17

A company has one cloud-based web server that is prone to downtime during maintenance. Which ot the following should the cloud engineer add to ensure high availability?

A. A redundant web server behind a load balancer

B. A backup cloud web server

C. A secondary network link to the web server

D. An autoscaling feature on the web server

Correct Answer:A
Adding a redundant web server behind a load balancer is the solution that will ensure high availability. If one server goes down for maintenance, the other can take over, ensuring that the web service remains available without interruption.References: High availability concepts, including the use of load balancers and redundant servers, are part of cloud infrastructure design as per CompTIA Cloud+.

Question 18

A cloud engineer is deploying a cloud solution that will be used on premises with need-to- know access. Which of the following cloud deployment models best meets this requirement?

A. Community

B. Public

C. Private

D. Hybrid

Correct Answer:C
A private cloud deployment model is the most appropriate when the requirement is for 'need-to-know' access, as it offers a more secure environment with resources dedicated to a single organization. It can be hosted on-premises or off-premises but is maintained on a private network, ensuring greater control over the data, security, and compliance when compared to other cloud models.
