  ---

  Explanation/Reference:

  Data sanitization is the process of deliberately, permanently, and irreversibly removing or destroying the data stored on a memory device. Data sanitization is a security best practice and often a compliance requirement for sensitive or confidential data. Data sanitization ensures that the data cannot be recovered by any means, even by advanced forensic tools. Data sanitization can be done by overwriting, degaussing, or physically destroying the storage media. When a company discontinues its use of a cloud provider, the provider should sanitize the data to prevent any unauthorized access, leakage, or breach of the company's data.

• Question 162:

  A small business wants to move its accounting operations to the cloud. Which of the following cloud service models would put the MOST liability on the provider with regard to shared responsibility?

  A. laaS
  B. BPaaS
  C. PaaS
  D. SaaS
  D. SaaS

  ---

  Explanation/Reference:

  SaaS stands for Software as a Service, which is a cloud service model that provides ready-to-use software applications over the internet. The cloud service provider (CSP) is responsible for managing and maintaining the software, including its development, deployment, updates, security, availability, and performance. The customer only needs to access the software through a web browser or a client application, and pay for the usage or subscription. SaaS puts the most liability on the provider with regard to shared responsibility, as the provider handles most of the security and operational tasks for the software, and the customer has minimal control and customization options. Examples of SaaS applications include email, CRM, ERP, accounting, and collaboration tools. The other cloud service models put less liability on the provider and more on the customer, as the customer has more control and responsibility over the cloud resources. IaaS stands for Infrastructure as a Service, which provides virtualized computing resources such as servers, storage, and networking over the internet. The CSP is responsible for securing and maintaining the physical infrastructure, while the customer is responsible for managing the operating system, applications, data, and configurations. PaaS stands for Platform as a Service, which provides a cloud-based environment for developing, testing, and deploying software applications. The CSP is responsible for managing the underlying infrastructure, middleware, and runtime environment, while the customer is responsible for developing, deploying, and managing the applications and data. BPaaS stands for Business Process as a Service, which provides a cloud-based platform for automating and orchestrating business processes. The CSP is responsible for managing the platform, including its integration, security, and scalability, while the customer is responsible for defining, executing, and monitoring the business processes and rules. Therefore, the correct answer is D. SaaS, as it puts the most liability on the provider with regard to shared responsibility.

• Question 163:

  The optimal, sequential order in which cloud resources should be recovered in the event of a major failure would be defined in the:

  A. recovery point objective.
  B. disaster recovery plan.
  C. incident response plan.
  D. network topology diagram.
  B. disaster recovery plan.

  ---

  Explanation/Reference:

  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.

• Question 164:

  A business analyst is using a public cloud provider's CRM service to manage contacts and organize all communication. Which of the following cloud service models is the analyst using?

  A. IaaS
  B. SaaS
  C. DBaaS D. PaaS
  B. SaaS

  ---

  Explanation/Reference:

  SaaS stands for Software as a Service, which is a cloud service model that provides the customer with a complete software application that is hosted and managed by the provider. The customer can access the software over the internet, without requiring any installation, configuration, or maintenance on their side. The customer only pays for the software usage, usually on a subscription or pay-per-use basis. A CRM service is an example of a SaaS application, as it allows the customer to manage contacts, organize communication, and track sales activities, without having to worry about the underlying infrastructure, platform, or software development. A public cloud provider is a provider that offers cloud services to the general public over the internet, such as Microsoft Azure, Amazon Web Services, or Google Cloud. SaaS is different from other cloud service models, such as IaaS, DBaaS, or PaaS. IaaS stands for Infrastructure as a Service, which provides the customer with the basic computing resources, such as servers, storage, network, and virtualization. The customer is responsible for the operating system, middleware, runtime, application, and data. DBaaS stands for Database as a Service, which provides the customer with a database management system that is hosted and managed by the provider. The customer is responsible for the data and the queries. PaaS stands for Platform as a Service, which provides the customer with a platform to develop, run, and manage applications without worrying about the infrastructure. The customer is responsible for the application code, data, and configuration. References: Cloud Service Models - CompTIA Cloud Essentials+ (CLO-002) Cert Guide, What is SaaS?

  The cloud consumer compliance team requires the IT department to patch and update cloud resources properly. Which of the following cloud service delivery models will BEST suit this need?

  A. SaaS
  B. DBaaS
  C. DRaaS
  D. IaaS
  D. IaaS

  ---

  Explanation/Reference:

  Infrastructure as a service (IaaS) is a cloud service delivery model that provides on-demand infrastructure resources to organizations via the cloud, such as compute, storage, networking, and virtualization4. IaaS is the most suitable cloud service delivery model for patching and updating cloud resources properly, as it gives the cloud consumer compliance team more control and flexibility over the operating system, middleware, virtual machines, and any apps or data5. IaaS also enables automation and orchestration of the provisioning process, as well as scalability and reliability of the infrastructure6.

• Question 166:

  Which of the following is related to data availability in the cloud?

  A. Resiliency
  B. Deduplication
  C. Scalability
  D. Elasticity
  A. Resiliency

  ---

  Explanation/Reference:

  Data availability in the cloud refers to the ability of cloud services to provide continuous and uninterrupted access to data, even in the event of a network disruption or a disaster. Resiliency is the ability of a system to recover quickly from failures and restore normal operations. Resiliency is related to data availability in the cloud because it ensures that data is not lost or corrupted due to failures and that data can be accessed by users and applications without delays or errors. Deduplication, scalability, and elasticity are not directly related to data availability in the cloud, although they may have some impact on the performance and efficiency of cloud services. Deduplication is the process of eliminating redundant copies of data to save storage space and bandwidth. Scalability is the ability of a system to handle increasing or decreasing workloads by adding or removing resources. Elasticity is the ability of a system to automatically adjust the amount of resources based on the current demand.

• Question 167:

  Which of the following would BEST provide access to a Windows VDI?

  A. RDP
  B. VPN
  C. SSH
  D. HTTPS
  A. RDP

  ---

  Explanation/Reference:

  RDP stands for Remote Desktop Protocol, which is a protocol that allows a user to remotely access and control a Windows-based computer or virtual desktop from another device over a network. RDP can be used to provide access to a Windows VDI, which is a virtual desktop infrastructure that delivers Windows desktops and applications as a cloud service. RDP can provide a full graphical user interface, keyboard, mouse, and audio support, as well as features such as clipboard sharing, printer redirection, and file transfer. RDP can be accessed by using the built-in Remote Desktop Connection client in Windows, or by using third-party applications or web browsers. RDP is more suitable for accessing a Windows VDI than other protocols, such as VPN, SSH, or HTTPS, which may not support the same level of functionality, performance, or security.

• Question 168:

  Which of the following stores transactions in a distributed ledger of which all users have a copy?

  A. Big Data
  B. Block chain
  C. Machine learning
  D. Artificial intelligence
  B. Block chain

  ---

  Explanation/Reference:

  A block chain is a type of distributed ledger that stores transactions in a public or private peer-to-peer network. Distributed ledgers use independent computers (referred to as nodes) to record, share, and synchronize transactions in their respective electronic ledgers instead of keeping data centralized as in a traditional ledger. A block chain organizes data into blocks, which are chained together in an append-only mode. Each block contains a timestamp and a cryptographic hash of the previous block, thus making the block chain an auditable, immutable history of all transactions in the network. All users have a copy of the block chain, which they can verify and validate by consensus. A block chain is different from other options, such as big data, machine learning, and artificial intelligence. Big data is a term that refers to the large volume, variety, and velocity of data that is generated, collected, and analyzed by various sources and applications. Machine learning is a branch of artificial intelligence that uses algorithms and data to learn from experience and improve performance without explicit programming. Artificial intelligence is a field of computer science that aims to create machines and systems that can perform tasks that normally require human intelligence, such as reasoning, learning, and decision making.

• Question 169:

  Which of the following describes the process of moving an application from an isolated data center to reduce latency and ensure close proximity to end users?

  A. Replication
  B. Zones
  C. Geo-redundancy
  D. Backup
  C. Geo-redundancy

  ---

  Explanation/Reference:

  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.

• Question 170:

  Which of the following DevOps options is used to integrate with cloud solutions?

  A. Provisioning
  B. API
  C. SOA
  D. Automation
  B. API

  ---

  Explanation/Reference:

  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.
