Different healthcare organizations have agreed to collaborate and build a cloud infrastructure that should minimize compliance costs and provide a high degree of security and privacy, as per regulatory requirements. This is an example of a:
Correct Answer:
B
The correct answer is B. Community cloud.
A community cloud is a cloud deployment model that involves a shared infrastructure among several organizations that have common interests, goals, or requirements. A community cloud can provide a high degree of security, privacy, and compliance, as well as cost savings and efficiency, for the participating organizations. A community cloud can be managed by one or more of the organizations, or by a third-party service provider .
A private cloud is a cloud deployment model that involves a dedicated infrastructure for a single organization. A private cloud can provide a high degree of control, customization, and security for the organization, but it may also incur higher costs and complexity. A private cloud can be managed by the organization itself, or by a third-party service provider.
A hybrid cloud is a cloud deployment model that involves a combination of two or more different cloud models, such as private, public, or community clouds. A hybrid cloud can provide the benefits of both models, such as scalability, flexibility, and cost-effectiveness, as well as address the challenges of each model, such as security, compliance, and performance. A hybrid cloud can be managed by the organization itself, or by one or more service providers .
A public cloud is a cloud deployment model that involves a shared infrastructure for multiple organizations or individuals. A public cloud can provide a high degree of scalability, accessibility, and affordability for the users, but it may also pose some risks in terms of security, privacy, and compliance. A public cloud is managed by a third-party service provider .

A systems administrator has migrated an internal application to a public cloud. The new web server is running under a TLS connection and has the same TLS certificate as the internal application that is deployed. However, the IT department reports that only internal users who are using new versions of the OSs are able to load the application home page.
Which of the following is the MOST likely cause of the issue?
Correct Answer:
D
Ciphers are algorithms or methods that are used to encrypt and decrypt data for secure communication. Strong ciphers are ciphers that use high-level encryption techniques and keys to provide stronger security and protection for data. The cloud web server is using strong ciphers that are not supported by older browsers is the most likely cause of the issue of only internal users who are using new versions of the OSs being able to load the application home page after the administrator configured a redirect from HTTP to HTTPS on the web server. Older browsers may not support the strong ciphers used by the cloud web server for HTTPS connections, which can result in a failure to establish a secure connection and load the application home page.

A cloud administrator has finished setting up an application that will use RDP to connect. During testing, users experience a connection timeout error.
Which of the following will MOST likely solve the issue?
Correct Answer:
D
TCP port 3389 is the default port used by Remote Desktop Protocol (RDP) to connect to a remote system or application over a network. Opening TCP port 3389 on the firewall or network device will most likely solve the issue of users experiencing a connection timeout error when trying to use RDP to connect to an application, as it will allow RDP traffic to pass through. If TCP port 3389 is closed or blocked, RDP traffic will be denied or dropped, resulting in a connection timeout error. References: CompTIA Cloud+ Certification Exam Objectives, page 15, section 2.8

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 .
