The marketing department likely stores large media files on its servers, leading to increased storage costs. This is because the marketing department is responsible for creating and distributing various types of digital content, such as videos, images, podcasts, and webinars, to promote the products and services of the enterprise. These media files tend to be large in size and require more storage space than other types of data, such as text documents or spreadsheets. Therefore, the marketing department consumes more storage resources than the other departments, which increases the monthly cloud costs for the enterprise. References: CompTIA Cloud Essentials+ CLO-002 Study Guide, Chapter 3: Cloud Service and Delivery Models, Section 3.2: Cloud Storage, Page 97

Geo-redundancy is the distribution of mission-critical components or infrastructures, such as servers, across multiple data centers that reside in different geographic locations1. Geo-redundancy acts as a safety net in case the primary site fails or in the event of a disaster or an outage that impacts an entire region1. Geo-redundancy also reduces latency and ensures close proximity to end users by delivering web content from the nearest data center2. Geo-redundancy is a common feature of cloud computing, as it provides high availability, reliability, and performance for cloud applications and services2.

Replication is the process of copying data from one location to another, such as from a primary site to a secondary site, or from one cloud provider to another3. Replication is a necessary but not sufficient condition for geo-redundancy, as it does not guarantee that the replicated data is accessible or consistent across different regions3. Replication can also introduce operational complexity and data synchronization issues3.

Zones are logical or physical partitions of a cloud provider’s infrastructure that offer high availability and fault tolerance within a region4. Zones are usually located in the same or nearby data centers, and are connected by low-latency network links4. Zones can help distribute the workload and prevent single points of failure, but they do not provide geo-redundancy, as they are still vulnerable to regional outages or disasters4.

Backup is the process of creating and storing copies of data for the purpose of recovery in case of data loss or corruption5. Backup is an important part of data protection and disaster recovery, but it does not provide geo-redundancy, as it does not ensure that the backup data is available or up-to-date in different regions5. Backup can also have longer recovery time and higher cost than geo-redundancy5. References: Use geo-redundancy to design highly available applications; Geo Redundancy Explained | Cloudify; Georedundancy - Open Telekom Cloud; Why geo-redundancy for cloud infrastructure is a ‘must have’; Geo-Redundancy: Why Is It So Important? | Unitrends.

Backup and recovery of data is considered a concept of availability, which is one of the three pillars of information security, along with confidentiality and integrity. Availability means that data and systems are accessible and usable by authorized users when needed. Backup and recovery of data ensures that data can be restored in case of loss, corruption, or disaster, and that business operations can continue or resume with minimal downtime. Cloud backup and recovery involves creating and storing copies of data in a secondary, offsite storage location, and using the copies to restore the original data in the event of data loss1. Cloud backup and recovery offers many benefits, such as scalability, cost-effectiveness, reliability, and automation234. References: Cloud Essentials+ CLO-002 Study Guide, Chapter 2: Cloud Concepts, Section 2.3: Explain aspects of IT security in the cloud, p. 47. Backup And Disaster Recovery | Google CloudHow does backup and data recovery work in the Cloud? - Devoteam G CloudData Recovery Explained | IBMWhat is Cloud Backup and Recovery | Rackspace Technology

A disaster recovery plan (DRP) is a document that defines the procedures and resources needed to restore normal operations after a major disruption. A DRP typically includes the following elements:

• The scope and objectives of the plan
• The roles and responsibilities of the DR team
• The inventory and location of critical assets and resources
• The recovery strategies and procedures for different scenarios
• The testing and maintenance schedule for the plan
• The communication plan for internal and external stakeholders

One of the key components of a DRP is the recovery sequence, which is the optimal, sequential order in which cloud resources should be recovered in the event of a major failure. The recovery sequence is based on the priority and dependency of the resources, as well as the recovery time objective (RTO) and recovery point objective (RPO) of the business. The recovery sequence helps to minimize the downtime and data loss, and ensure the continuity of the business operations.

A recovery point objective (RPO) is the maximum acceptable amount of data loss measured in time. It indicates how often the data should be backed up and how much data can be restored after a disaster. A recovery time objective (RTO) is the maximum acceptable amount of time that a system or application can be offline after a disaster. It indicates how quickly the system or application should be restored and how much downtime can be tolerated by the business.

An incident response plan (IRP) is a document that defines the procedures and actions to be taken in response to a security breach or cyberattack. An IRP typically includes the following elements:

• The scope and objectives of the plan
• The roles and responsibilities of the incident response team
• The incident identification and classification criteria
• The incident containment, eradication, and recovery steps
• The incident analysis and reporting methods
• The incident prevention and improvement measures

A network topology diagram is a visual representation of the physical and logical layout of a network. It shows the devices, connections, and configurations of the network. A network topology diagram can help to identify the potential points of failure, the impact of a failure, and the recovery options for a network. However, it does not define the optimal, sequential order in which cloud resources should be recovered in the event of a major failure.
