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. References:

 Deduplication is a technique that eliminates redundant copies of data from a storage device, such as a SAN disk drive. Deduplication can reduce the amount of storage space required and improve the performance and efficiency of the storage system. Deduplication works by identifying and removing duplicate blocks of data within or across files, and replacing them with pointers to a single copy of the data. Deduplication can be performed at the file level or the block level, depending on the granularity and the algorithm used. Deduplication is often used in backup and archive scenarios, where data is highly redundant and can be deduplicated across multiple backups. Deduplication can also be used in primary storage scenarios, such as SAN disk drives, especially for all-flash arrays that implement deduplication techniques. Deduplication is different from compression, which is another technique that reduces the size of data by removing redundant information within a data block. Deduplication and compression can work together to achieve higher storage savings. Deduplication is also different from encryption, which is a technique that protects the confidentiality and integrity of data by transforming it into an unreadable form using a secret key. Deduplication is not effective for encrypted data, as encryption makes the data appear random and unique. Deduplication is also different from sanitization, which is a technique that permanently erases data from a storage device, making it unrecoverable. Deduplication does not erase data, but rather consolidates it and removes duplicates. Therefore, the correct term for eliminating redundant copies of data from a SAN disk drive is deduplication. References: Using Deduplication and Compression, Understanding Data Deduplication, 7.6 Using Deduplication techniques in SAN infrastrucutre.

API stands for Application Programming Interface, which is a set of rules and protocols that allow different software components or systems to communicate and exchange data. API is used to integrate with cloud solutions because it enables developers to access the cloud services and resources programmatically, without having to deal with the underlying infrastructure or platform details. API also allows for automation, scalability, and interoperability of cloud applications and services.

An identity and access control management policy is a document that defines the roles, responsibilities, and rules for managing the identities and access rights of users in an organization1. It specifies how users are authenticated, authorized, and audited when they access the organization’s resources, such as systems, applications, data, and networks1. An identity and access control management policy also describes the processes and procedures for creating, modifying, suspending, and deleting user accounts and privileges, as well as the standards and guidelines for selecting and managing passwords, tokens, certificates, and other authentication factors1. An identity and access control management policy can help the systems administrator understand the user privileges for each role in the company, as it defines the access levels and permissions that are granted to different types of users, such as employees, contractors, vendors, partners, and customers1. The policy also outlines the criteria and conditions for granting, changing, or revoking access rights, based on the principle of least privilege and the need-to-know basis1. By following the identity and access control management policy, the systems administrator can ensure that the new user for the human resources department has the appropriate and secure access to the resources that are relevant to their job function and responsibilities1. References: 1: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), Chapter 3: Cloud Planning, Section 3.2: Cloud Adoption, Subsection 3.2.1: Identity and Access Management

Reserved instances are a type of cloud pricing model that allows customers to reserve a certain amount of cloud resources for a fixed period of time, usually one or three years, and pay a lower rate than the on-demand or pay-as-you-go model. Reserved instances are suitable for workloads that have predictable and stable resource consumption, as they can help customers save up to 75% of the cloud costs compared to the on-demand model1. However, reserved instances also require a long-term commitment and upfront payment, which may reduce the flexibility and scalability of the cloud.

The other options are not likely to help the company reduce the cost of infrastructure:

• Pay-as-you-go: This is a type of cloud pricing model that allows customers to pay only for the resources they use, without any upfront or long-term commitment. Pay-as-you-go is suitable for workloads that have variable and unpredictable resource consumption, as it provides flexibility and scalability. However, pay-as-you-go is also the most expensive cloud pricing model, as it charges a higher rate per unit of resource than the reserved or spot instances models1.
• Spot instances: This is a type of cloud pricing model that allows customers to bid for unused cloud resources at a discounted rate, usually up to 90% lower than the on-demand model1. Spot instances are suitable for workloads that are flexible, interruptible, and not time-sensitive, as they can be terminated at any time by the cloud provider when the demand or price increases. Spot instances can help customers save a lot of money, but they also introduce a high level of uncertainty and risk to the cloud environment.
• Bring your own license: This is a type of cloud pricing model that allows customers to use their existing software licenses on the cloud, instead of purchasing new licenses from the cloud provider. Bring your own license can help customers reduce the software costs, but it does not affect the cost of infrastructure, which is based on the amount and type of cloud resources used2.

Auto-scaling is a feature that helps to adjust the capacity of a system automatically based on its current demand. The goal of auto-scaling is to maintain the performance of the system and to reduce costs by only using the resources that are actually needed1. If the cloud administrator configures auto-scaling for the application, the system can scale out (add more instances) during the peak hours of 1:00 p.m. and 3:00 p.m. every day, and scale in (remove instances) when the demand is low. This way, the application can handle the increased workload without degrading its performance, and the users can have a better experience. References: CompTIA Cloud Essentials+ Certification Study Guide, Second Edition (Exam CLO-002), Chapter 2: Cloud Computing Concepts, pages 41-42.

TCO, or Total Cost of Ownership, is a metric that helps to estimate the total cost of acquiring and maintaining a product, service, or investment over its lifetime. TCO includes not only the initial purchase price, but also any ongoing costs, such as maintenance, support, upgrades, licensing, or disposal. TCO is useful for comparing different options and making informed decisions based on the long-term implications of each option. In this case, the company needs to do a cost analysis for a three-year contract renewal with a SaaS provider that changed its licensing model. To do this, the company needs to consider the TCO of the SaaS service, which includes the cost of the license, the cost of any additional features or services, the cost of integration with other systems, the cost of training and support, and the cost of any potential risks or issues. By calculating the TCO, the company can forecast the entire financial impact of the contract renewal over the three-year period and compare it with other alternatives. ROI, or Return on Investment, is a metric that measures the performance or profitability of an investment. ROI compares the amount of money invested in a project or asset with the amount of money gained or saved as a result of that investment. ROI is useful for evaluating the effectiveness and efficiency of an investment and determining if it is worth pursuing. However, ROI does not account for the total cost of ownership of an investment, nor does it consider the time value of money or the opportunity cost of investing in something else. Therefore, ROI is not the best metric to use for forecasting the entire financial impact of a contract renewal over a long period of time. SOW, or Statement of Work, is a document that defines the scope, deliverables, timeline, and terms of a project or contract. SOW is useful for establishing the expectations and responsibilities of both parties involved in a project or contract and ensuring that they are aligned and agreed upon. However, SOW does not provide a financial forecast or analysis of a project or contract, nor does it compare different options or alternatives. Therefore, SOW is not the best metric to use for doing a cost analysis for a contract renewal. RFI, or Request for Information, is a document that solicits information from potential vendors or suppliers about their products, services, or capabilities. RFI is useful for gathering information and data that can help to evaluate and compare different options or alternatives and make informed decisions. However, RFI does not provide a financial forecast or analysis of a project or contract, nor does it calculate the total cost of ownership or the return on investment of each option or alternative. Therefore, RFI is not the best metric to use for doing a cost analysis for a contract renewal. References: 1, 2, 3

VDI, or Virtual Desktop Infrastructure, is the result of performing a physical-to-virtual migration of desktop workstations. VDI is a technology that allows users to access and run desktop operating systems and applications from a centralized server in a data center or a cloud, instead of from a physical machine on their premises. VDI provides users with virtual desktops that are delivered over a network to various devices, such as laptops, tablets, or thin clients1. VDI offers several benefits, such as improved security, reduced costs, increased flexibility, and enhanced performance2.

SaaS, or Software as a Service, is not the result of performing a physical-to-virtual migration of desktop workstations, but a cloud service model that provides ready-to-use software applications that run on the cloud provider’s infrastructure and are accessed via a web browser or an API3. SaaS does not involve migrating desktop workstations, but using software applications that are hosted and managed by the cloud provider.

IaaS, or Infrastructure as a Service, is not the result of performing a physical-to-virtual migration of desktop workstations, but a cloud service model that provides access to basic computing resources, such as servers, storage, network, and virtualization, that are hosted on the cloud provider’s data centers and are rented on-demand. IaaS does not involve migrating desktop workstations, but renting infrastructure resources that can be used to host various workloads.

VPN, or Virtual Private Network, is not the result of performing a physical-to-virtual migration of desktop workstations, but a technology that creates a secure and encrypted connection between a device and a network over the internet. VPN does not involve migrating desktop workstations, but connecting to a network that can provide access to remote resources or services. References: What is VDI?
