• Question 191:

  Which of the following allows for the management of network policies from a central portal while maintaining a hardware-agnostic approach?

  A. Virtual private network
  B. Software-defined network
  C. Load balancing
  D. Direct Connect
  B. Software-defined network

  ---

  Explanation/Reference:

  A software-defined network (SDN) is a network architecture that allows for the management of network policies from a central portal while maintaining a hardware- agnostic approach. SDN separates the control plane, which is responsible for making decisions about how to route traffic, from the data plane, which is responsible for forwarding traffic based on the control plane's instructions. SDN enables network administrators to configure, monitor, and manage network devices and services using a software application, regardless of the vendor or type of hardware. SDN also provides automation, programmability, scalability, and flexibility for network operations. A virtual private network (VPN) is a network technology that creates a secure and encrypted connection over a public network, such as the Internet. A VPN allows remote users to access a private network and its resources securely. A VPN is not related to the management of network policies from a central portal or the hardware-agnostic approach of SDN. Load balancing is a network technique that distributes traffic across multiple servers or devices to optimize performance, reliability, and availability. Load balancing can be implemented using hardware or software, but it does not provide the same level of centralized management and control as SDN. Direct Connect is a service offered by some cloud providers that allows customers to establish a dedicated network connection between their on-premises network and the cloud provider's network. Direct Connect bypasses the public Internet and provides lower latency, higher bandwidth, and more consistent network performance. However, Direct Connect is not a generic network architecture that supports a hardware-agnostic approach, and it does not offer the same degree of network programmability and automation as SDN.

• Question 192:

  Which of the following BEST explains why there should be an established communication policy between CSPs and clients?

  A. To set guidelines for securing network traffic for all communications with endpoints on the corporate local area network
  B. To ensure all staff know the acceptable guidelines for representing themselves on social media.
  C. To have protocols in place for notifying staff when a cloud outage occurs.
  D. To have proper procedures in place for interactions between internal departments and cloud vendors submitting bids for software or service.
  C. To have protocols in place for notifying staff when a cloud outage occurs.

  ---

  Explanation/Reference:

  A communication policy between CSPs and clients is a set of rules and guidelines that define how, when, and what information is exchanged between the parties involved in a cloud service relationship. A communication policy can help ensure transparency, accountability, trust, and collaboration between CSPs and clients, as well as improve the quality and efficiency of the cloud service delivery and management. One of the main reasons why there should be an established communication policy between CSPs and clients is to have protocols in place for notifying staff when a cloud outage occurs. A cloud outage is a disruption or interruption of the availability or functionality of a cloud service, which can affect the performance, reliability, and security of the cloud service and its users. A cloud outage can be caused by various factors, such as hardware failures, software bugs, network issues, human errors, cyberattacks, or natural disasters. A communication policy can help define the roles and responsibilities of the CSPs and clients in the event of a cloud outage, such as who should report, monitor, escalate, resolve, and communicate the outage, and how they should do so. A communication policy can also help specify the communication channels, methods, formats, and frequencies that should be used to inform the relevant staff and stakeholders about the outage, such as email, phone, text, web portal, dashboard, or social media. A communication policy can also help establish the communication standards, expectations, and metrics that should be followed to ensure the accuracy, timeliness, and completeness of the outage information, such as the cause, impact, status, duration, and resolution of the outage. By having protocols in place for notifying staff when a cloud outage occurs, a communication policy can help minimize the negative effects of the outage, such as customer dissatisfaction, revenue loss, reputation damage, or legal liability. A communication policy can also help enhance the positive outcomes of the outage, such as customer loyalty, service improvement, incident learning, or risk mitigation. Therefore, option C is the best explanation of why there should be an established communication policy between CSPs and clients. Option A is incorrect because it does not explain why there should be a communication policy between CSPs and clients, but rather how to secure network traffic for all communications with endpoints on the corporate local area network. Network security is an important aspect of cloud service delivery and management, but it is not the same as communication policy. Option B is incorrect because it does not explain why there should be a communication policy between CSPs and clients, but rather how to ensure all staff know the acceptable guidelines for representing themselves on social media. Social media is one of the possible communication channels that can be used to exchange information between CSPs and clients, but it is not the same as communication policy. Option D is incorrect because it does not explain why there should be a communication policy between CSPs and clients, but rather how to have proper procedures in place for interactions between internal departments and cloud vendors submitting bids for software or service. Cloud vendor selection is an important aspect of cloud service procurement and contracting, but it is not the same as communication policy.

• Question 193:

  An IT company is planning to migrate its current infrastructure to the cloud due to support no longer being available and dependence on some legacy databases. Which of the following would be the BEST migration approach?

  A. Rip and replace
  B. Phased
  C. Hybrid
  D. Lift and shift
  D. Lift and shift

  ---

  Explanation/Reference:

  Lift and shift is a cloud migration approach that involves moving applications to the cloud as-is, without making any major changes to the application code or architecture. This approach is suitable for legacy applications that depend on specific databases or platforms that are no longer supported or available on-premise. Lift and shift can help reduce the cost and complexity of migration, while preserving the functionality and performance of the applications. However, lift and shift may not take full advantage of the cloud features and benefits, such as scalability, elasticity, and automation. Therefore, some applications may require further optimization or refactoring after the initial migration.

• Question 194:

  A software company that develops mobile applications is struggling with the complicated process of deploying the development, testing. QA. and staging environments. Which of the following cloud service models offers the BEST automated development environment for the software company?

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

  ---

  Explanation/Reference:

  PaaS, or Platform as a Service, is a cloud service model that provides a complete, flexible, and cost-effective cloud platform for developing, running, and managing applications1. PaaS offers the best automated development environment for the software company, because it eliminates the need to install, configure, and maintain the hardware, software, and infrastructure required for application development and deployment. PaaS also provides access to a variety of tools, frameworks, languages, and services that can simplify and accelerate the development process. PaaS enables developers to focus on writing code, testing, and deploying applications, without worrying about the underlying platform. PaaS also supports continuous integration and delivery, which can automate the deployment of different environments, such as development, testing, QA, and staging2. SaaS, or Software as a Service, is 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 offer an automated development environment for the software company, because it does not allow developers to create or modify the software applications, only to use them as end-users. SaaS is suitable for applications that have standard features and functionalities, such as email, CRM, or ERP, but not for custom applications that require specific requirements and capabilities. IaaS, or Infrastructure as a Service, is 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 offer an automated development environment for the software company, because it still requires developers to install, configure, and manage the software stack, such as operating systems, middleware, databases, and development tools, on top of the infrastructure. IaaS provides more control and flexibility over the infrastructure, but also more complexity and responsibility for the developers. CaaS, or Containers as a Service, is a cloud service model that provides a platform for deploying and managing containerized applications on the cloud provider's infrastructure. CaaS does not offer an automated development environment for the software company, because it assumes that the applications are already developed and packaged into containers, which are isolated and portable units of software that include all the dependencies and configurations needed to run them. CaaS provides a way to orchestrate, scale, and secure the containers, but not to develop them. CaaS is suitable for applications that are designed with a microservices architecture, which divides the application into smaller and independent components that communicate with each other via APIs.

• Question 195:

  Which of the following is a valid mechanism for achieving interoperability when extracting and pooling data among different CSPs?

  A. Use continuous integration/continuous delivery.
  B. Recommend the use of the same CLI client.
  C. Deploy regression testing to validate pooled data.
  D. Adopt the use of communication via APIs.
  D. Adopt the use of communication via APIs.

  ---

  Explanation/Reference:

  APIs (application programming interfaces) are sets of rules and protocols that enable communication and data exchange between different applications or systems. APIs can facilitate interoperability when extracting and pooling data among different CSPs (cloud service providers) by allowing standardized and secure access to the data sources and services offered by each CSP. APIs can also enable automation, scalability, and customization of cloud solutions.

• Question 196:

  Which of the following can be used to achieve automation, environment consistency, and standardization of computer resources in a cloud environment?

  A. Content management system
  B. Automation
  C. Service-oriented architecture
  D. Infrastructure as code
  D. Infrastructure as code

  ---

  Explanation/Reference:

  Infrastructure as code (IaC) is the ability to provision and support your computing infrastructure using code instead of manual processes and settings1. IaC can be used to achieve automation, environment consistency, and standardization of computer resources in a cloud environment, as it eliminates the need for developers to manually configure and manage servers, operating systems, database connections, storage, and other infrastructure elements every time they want to develop, test, or deploy a software application2. IaC also enables developers to easily duplicate, track, and version their infrastructure, and to avoid configuration errors and drifts that can cause deployment failures2. IaC is an essential DevOps practice, as it enables faster and more reliable software delivery lifecycles2.

• Question 197:

  For security reasons, a cloud service that can be accessed from anywhere would make BEST use of:

  A. replication.
  B. multifactor authentication.
  C. single sign-on.
  D. data locality
  B. multifactor authentication.

  ---

  Explanation/Reference:

  Multifactor authentication is a security method that requires users to provide more than one piece of evidence to verify their identity before accessing a cloud service. For example, users may need to enter a password, a code sent to their phone or email, a biometric scan, or a physical token. Multifactor authentication can enhance the security of a cloud service that can be accessed from anywhere, as it can prevent unauthorized access even if the password is compromised or stolen. Multifactor authentication can also protect the cloud service from phishing, brute force, or replay attacks, as well as comply with regulatory or industry standards. Multifactor authentication is different from other options, such as replication, single sign-on, or data locality. Replication is the process of copying data or resources across multiple locations, such as regions, zones, or data centers, to improve availability, performance, or backup. Single sign-on is a user authentication method that allows users to access multiple cloud services with one set of credentials, such as username and password. Data locality is the principle of storing data close to where it is used, such as in the same region, country, or jurisdiction, to improve performance, security, or compliance. While these options may also have some benefits for a cloud service that can be accessed from anywhere, they do not directly address the security concern, which is the focus of the question.

• Question 198:

  Which of the following cloud computing characteristics is a facilitator of a company's organizational agility?

  A. Professional services
  B. Managed services
  C. Reduced time to market
  D. Licensing model
  C. Reduced time to market

  ---

  Explanation/Reference:

  Organizational agility is the ability of a company to quickly adapt to changing market and environmental conditions in a profitable and efficient way. Cloud computing can facilitate organizational agility by providing rapid provisioning of IT resources, scalability, flexibility, and cost-effectiveness. One of the benefits of cloud computing is reduced time to market, which means that a company can launch new products or services faster and more efficiently than its competitors. This can give the company a competitive edge and increase customer satisfaction. Reduced time to market is a characteristic of cloud computing that enables organizational agility, not a result of it. Therefore, it is the correct answer.

• Question 199:

  An organization is determining an acceptable amount of downtime. Which of the following aspects of cloud design should the organization evaluate?

  A. RPO
  B. RTO
  C. ERP
  D. TCO
  B. RTO

  ---

  Explanation/Reference:

  RTO stands for Recovery Time Objective, which is the time frame within which an IT resource must fully recover from a disruptive event1. RTO is a measure of the acceptable amount of downtime that an organization can tolerate in case of a disaster or a failure2. RTO helps an organization to plan and design its cloud backup and disaster recovery strategy, as it determines how quickly the cloud services and applications need to be restored to resume normal business operations2. RTO also helps an organization to estimate the potential costs and losses associated with downtime, and to balance them with the costs and resources required for recovery2. RTO is different from RPO, which stands for Recovery Point Objective, and is the acceptable amount of data loss that an organization can tolerate in case of a disaster or a failure1. RPO helps an organization to plan and design its cloud backup frequency and retention policy, as it determines how much data needs to be backed up and how often2. RPO also helps an organization to estimate the potential costs and losses associated with data loss, and to balance them with the costs and resources required for backup2. ERP stands for Enterprise Resource Planning, which is a type of software system that integrates and automates various business processes and functions, such as accounting, inventory, human resources, customer relationship management, and more3. ERP is not directly related to cloud design or downtime, although some ERP systems can be deployed on the cloud or use cloud services3. TCO stands for Total Cost of Ownership, which is a financial estimate that considers all the direct and indirect costs associated with acquiring and operating an asset or a service over its lifetime. TCO is a useful metric for comparing different cloud solutions and providers, as it helps an organization to evaluate the true costs and benefits of cloud adoption. TCO is not directly related to cloud design or downtime, although downtime can affect the TCO of a cloud solution by increasing the costs and reducing the benefits.
