The SLA should include theRecovery Time Objective (RTO)to satisfy this requirement. The RTO is the maximum acceptable time that an application or service can be unavailable after a disaster or disruption. It defines the target duration for restoring the functionality and performance of the application or service. The RTO is usually measured in hours or days, depending on the criticality of the application or service. In this case, the requirement states that the application must be restored within six hours, which means that the RTO should be six hours or less. The other options are not relevant to this requirement. TheMean Time to Repair (MTTR)is the average time that it takes to fix a faulty component or system. TheRecovery Point Objective (RPO)is the maximum acceptable amount of data loss that can occur after a disaster or disruption. It defines the point in time to which the data must be restored. The RPO is usually measured in minutes or hours, depending on the frequency of data backups. TheReturn on Investment (ROI)is the ratio of the net profit to the initial cost of an investment. It measures the financial benefit of an investment over time.Reference: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), Chapter 3: Business Principles of Cloud Environments, Section 3.2: Cloud Assessments, p. 103-104.

A service level agreement (SLA) is a contract between a cloud service provider (CSP) and a customer that defines the level of service, performance, availability, and responsibilities of both parties1.An SLA may also include the notification process a CSP follows after discovering a breach of customer data, such as the time frame, the communication channels, the content and format of the notification, and the remediation actions2.A communication plan is a document that outlines the objectives, strategies, and tactics for communicating with different stakeholders, but it may not specify the details of the breach notification process3.An incident response policy is a set of guidelines and procedures for responding to security incidents, such as identifying, containing, analyzing, and recovering from them, but it may not be shared with the customer by the CSP4.Access controls are the mechanisms and policies that regulate who can access what resources and data in a cloud environment, but they are not related to the breach notification process5.Reference:

Private key encryption, also known as symmetric key encryption, is a method of encrypting data using a single secret key that is shared by both the sender and the receiver of the message1. Private key encryption ensures that only the authorized parties who have the same key can access the encrypted data, while preventing unauthorized parties from reading or modifying it.Therefore, private key encryption is mainly used to protect the confidentiality of data, which is the security concern that deals with preventing unauthorized disclosure of information2.

Confidentiality is one of the three main goals of information security, along with integrity and availability. Integrity refers to the security concern that deals with preventing unauthorized modification or corruption of information.Availability refers to the security concern that deals with ensuring timely and reliable access to information2.Authorization, on the other hand, is not a security concern, but a security mechanism that deals with granting or denying access rights to information based on predefined policies and rules3.

A cloud developer chooses to use private key encryption for all traffic in a new application.This best describes the security concern of confidentiality, as the developer wants to ensure that only the intended recipients can access the encrypted data, while keeping it secret from anyone else.Reference:1: https://www.comptia.org/training/books/cloud-essentials-clo-002-study-guide, Chapter 8, page 274-2752: https://www.comptia.org/training/books/cloud-essentials-clo-002-study-guide, Chapter 8, page 263-2643: https://www.comptia.org/training/books/cloud-essentials-clo-002-study-guide, Chapter 8, page 268-269

A content delivery network (CDN) is a technology that distributes web content across multiple servers in different geographic locations to improve user experience11.A CDN can be used to deploy web applications and files globally, so that users can access them faster and more reliably from their nearest server12.A CDN also reduces bandwidth consumption and network congestion by caching static content at the edge servers13.

A virtual private network (VPN) is a technology that creates a secure and encrypted connection over a public network, such as the internet, between two or more endpoints1.A VPN can be used to connect on-premises resources to resources located in a cloud environment, such as a virtual private cloud (VPC), which is a private network hosted within a public cloud2. A VPN allows the on-premises and cloud resources to communicate with each other as if they were on the same local network, without exposing the traffic to the public internet.A VPN can help to ensure the privacy, security, and reliability of the data and applications that are transferred between the on-premises and cloud environments3.

A VPN is different from the other options listed in the question, which are not directly related to connecting on-premises resources to resources located in a cloud environment. An access control list (ACL) is a list of rules that defines who or what can access a specific resource, such as a file, a folder, a network, or a service. An ACL can help to enforce the security and authorization policies of the resource owner, but it does not create a secure connection between the on-premises and cloud environments. A secure file transfer protocol (SFTP) is a protocol that uses Secure Shell (SSH) to securely transfer files over a network. SFTP can help to protect the files from unauthorized access, modification, or interception, but it does not create a secure connection between the on-premises and cloud environments. A software-defined network (SDN) is a network architecture that decouples the network control and data planes, and allows the network to be programmatically configured and managed by software applications. SDN can help to improve the flexibility, scalability, and performance of the network, but it does not create a secure connection between the on-premises and cloud environments.
