• Question 91:

  A company is planning to integrate the processes of several applications and assign a manager to oversee the technical coordination to improve efficiency. Which of the following would be BEST for coordinating the processes?

  A. Orchestration
  B. Scripting
  C. Continuous integration
  D. Continuous delivery
  A. Orchestration

  ---

  Explanation/Reference:

  Orchestration is the best option for coordinating the processes of several applications and assigning a manager to oversee the technical coordination to improve efficiency. Orchestration is the combined automation of apps, workloads, supporting resources, and infrastructure across one or more cloud platforms1. It commonly includes imperative and/or declarative methods to drive automation1. Orchestration introduces and enforces a workflow for automated activities of various processes to deliver the desired service to its client2. Orchestration helps IT organizations reduce manual, repetitive work, better standardize their deployments and operations, and accelerate delivery1. Orchestration also enables businesses to easily add or remove computing resources, on demand, without significant hardware investment or infrastructure changes2. Orchestration ensures that businesses can efficiently and seamlessly handle varying workloads, optimize resource utilization, and enhance the overall reliability and performance of cloud computing systems3. Orchestration is different from the other options listed in the question, which are not directly related to coordinating the processes of several applications. Scripting is the use of code to perform a specific task or operation on a single component of an application, workload, resource, or infrastructure within a cloud platform1. Scripting is one of the building blocks for delivering cloud orchestration, but it does not provide the coordination, arrangement, or end-to-end automation of the deployment of services in a cloud-based environment2. Continuous integration is the practice of merging code changes from multiple developers into a shared repository frequently, usually several times a day, to detect and resolve errors early4. Continuous integration is a part of the DevOps methodology, which aims to improve the quality and speed of software delivery, but it does not address the orchestration of the processes of several applications across multiple cloud platforms1. Continuous delivery is the practice of releasing software updates to production in small increments, usually after passing automated tests, to ensure that the software is always in a deployable state4. Continuous delivery is another part of the DevOps methodology, which aims to reduce the risk and cost of software deployment, but it does not address the orchestration of the processes of several applications across multiple cloud platforms1.

• Question 92:

  A cloud administrator needs to enable users to access business applications remotely while ensuring these applications are only installed on company-controlled equipment. All users require the ability to modify personal working environments. Which of the following is the BEST solution?

  A. SSO
  B. VDI
  C. SSH
  D. VPN
  B. VDI

  ---

  Explanation/Reference:

  The best solution for this scenario is Virtual Desktop Infrastructure (VDI). VDI is a cloud service model that provides users with virtual desktops that run on a centralized server. Users can access their virtual desktops remotely from any device, such as a laptop, tablet, or smartphone, using a thin client or a web browser. VDI enables users to access business applications without installing them on their own devices, which ensures that these applications are only installed on company-controlled equipment. VDI also allows users to modify their personal working environments, such as desktop settings, wallpapers, or preferences, which are saved on the server and persist across sessions. VDI can offer benefits such as improved security, reduced hardware costs, centralized management, and enhanced user experience. The other options are not the best solutions for this scenario. Single Sign-On (SSO) is a cloud service that enables users to log in to multiple applications or systems with one set of credentials, which simplifies authentication and improves security. However, SSO does not provide users with remote access to business applications or personal working environments. Secure Shell (SSH) is a network protocol that allows secure remote access to a server or a device using encryption and authentication. SSH can be used to execute commands, transfer files, or tunnel network traffic. However, SSH does not provide users with virtual desktops or business applications. Virtual Private Network (VPN) is a network technology that creates a secure connection between a remote device and a private network over a public network, such as the Internet. VPN can be used to access network resources, such as files, printers, or applications, that are not available otherwise. However, VPN does not provide users with virtual desktops or personal working environments.

• Question 93:

  Which of the following is the cloud storage technology that would allow a company with 12 nearly identical servers to have the SMALLEST storage footprint?

  A. Capacity on demand
  B. Compression
  C. Software-defined storage
  D. Deduplication
  D. Deduplication

  ---

  Explanation/Reference:

  Deduplication is the cloud storage technology that would allow a company with 12 nearly identical servers to have the smallest storage footprint. Deduplication is the process of eliminating redundant or duplicate data blocks within a storage system, and replacing them with pointers to a single copy of the data. Deduplication can reduce the amount of storage space required, as well as the bandwidth and cost of data transfer. Deduplication is especially effective for data that has a high degree of similarity, such as backup data, virtual machine images, or server data. Deduplication can be performed at the source or the target, and at the file or the block level.

• Question 94:

  A cloud administrator is reviewing the requirements for a SaaS application and estimates downtime will be very expensive for the organization. Which of the following should the administrator configure to minimize downtime? (Choose two.)

  A. Continuous deployment
  B. Right-sizing
  C. Availability zones
  D. Geo-redundancy
  E. Hardening
  F. Backups
  C. Availability zones
  D. Geo-redundancy

  ---

  Explanation/Reference:

  Availability zones and geo-redundancy are two strategies that can help minimize downtime for a SaaS application. Availability zones are distinct locations within a cloud region that are isolated from each other and have independent power, cooling, and networking. They provide high availability and fault tolerance by allowing the SaaS application to run on multiple servers across different zones. If one zone fails, the application can continue to operate on the other zones without interruption. Geo- redundancy is the replication of data and services across multiple geographic regions. It provides disaster recovery and business continuity by allowing the SaaS application to switch to another region in case of a major outage or a natural disaster. Geo-redundancy also improves performance and latency by serving users from the nearest region.

• Question 95:

  Which of the following is the BEST way to secure a web session to a hosted e-commerce website?

  A. SSL
  B. VPN
  C. Firewall
  D. DNS
  A. SSL

  ---

  Explanation/Reference:

  SSL (Secure Sockets Layer) is the best way to secure a web session to a hosted e-commerce website. SSL is a protocol that encrypts the data exchanged between a web browser and a web server, ensuring that no one can intercept, modify, or steal the information. SSL also provides authentication, which verifies the identity of the web server and the web browser, preventing impersonation or spoofing attacks. SSL is essential for e- commerce websites, as they handle sensitive data, such as credit card numbers, personal information, and login credentials, that need to be protected from hackers and cybercriminals. SSL also helps to build trust and confidence among customers, as they can see that the website is secure and legitimate. SSL can be recognized by the presence of a padlock icon and the HTTPS prefix in the web address. To enable SSL, e-commerce websites need to obtain and install an SSL certificate from a trusted certificate authority (CA), which is a third-party organization that issues and validates SSL certificates. SSL certificates can vary in price, validity, and level of security, depending on the type and provider of the certificate. Some web hosts and e-commerce platforms may offer free or discounted SSL certificates as part of their services.

• Question 96:

  Which of the following is a cloud service model that organizations use when their third-party ERP tool is provided as a complete service?

  A. Public cloud
  B. SaaS
  C. Hybrid cloud
  D. IaaS
  B. SaaS

  ---

  Explanation/Reference:

  SaaS, or software as a service, is a cloud service model that provides ready- to-use, cloud-hosted application software to customers. Customers do not need to install, manage, or maintain the software; they simply access it via an internet connection, usually through a web browser. SaaS applications are typically offered on a subscription or pay- per-use basis. Examples of SaaS applications include email, CRM, ERP, office productivity, and collaboration tools12. SaaS is different from the other cloud service models in terms of the level of abstraction and control. In SaaS, the cloud service provider manages everything from the underlying infrastructure to the application software, while the customer only controls the application settings and data. In contrast, in IaaS (infrastructure as a service), the customer has more control and responsibility over the servers, storage, networking, and operating systems, while the cloud service provider only manages the physical infrastructure. In PaaS (platform as a service), the customer has control and responsibility over the applications and data, while the cloud service provider manages the underlying infrastructure and the development tools and platforms12. Therefore, when an organization uses a third-party ERP tool as a complete service, it is using the SaaS cloud service model. The organization does not need to worry about the installation, configuration, or maintenance of the ERP software; it only needs to access it via the internet and pay for the usage. The cloud service provider takes care of the rest.

• Question 97:

  A large enterprise has the following invoicing breakdown of current cloud consumption spend:

  

  The level of resources consumed by each department is relatively similar. Which of the following is MOST likely affecting monthly costs?

  A. The servers in use by the marketing department are in an availability zone that is generally expensive.
  B. The servers in use by the accounting and IT operations departments are in different geographic zones with lower pricing.
  C. The accounting and IT operations departments are choosing to bid on non-committed resources.
  D. The marketing department likely stores large media files on its servers, leading to increased storage costs.
  D. The marketing department likely stores large media files on its servers, leading to increased storage costs.

  ---

  Explanation/Reference:

  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.

• Question 98:

  A document that outlines the scope of a project, specific deliverables, scheduling, and additional specific details from the client/buyer is called a:

  A. statement of work.
  B. standard operating procedure.
  C. master service document.
  D. service level agreement.
  A. statement of work.

  ---

  Explanation/Reference:

  A statement of work (SOW) is a document that outlines the scope of a project, specific deliverables, scheduling, and additional specific details from the client/buyer1. A SOW defines what the service provider will do for the client and how they

  will do it, as well as the expected outcomes and quality standards2. A SOW is typically used as a supplement to a master service agreement (MSA) or a contract that establishes the general terms and conditions of the business relationship3.

• Question 99:

  Which of the following testing techniques provides the BEST isolation for security threats?

  A. Load
  B. Regression
  C. Black box
  D. Sandboxing
  D. Sandboxing

  ---

  Explanation/Reference:

  Sandboxing is a testing technique that provides the best isolation for security threats. Sandboxing is a technique that creates a virtual environment that mimics the real system or application, but isolates it from the rest of the network. Sandboxing allows testers to run potentially malicious code or inputs without affecting the actual system or application, or exposing it to external attacks. Sandboxing can help testers to identify and analyze security threats, such as malware, ransomware, or zero-day exploits, without risking the integrity or availability of the real system or application. Sandboxing can also help testers to evaluate the effectiveness of security controls, such as antivirus, firewall, or encryption, in preventing or mitigating security threats.

• Question 100:

  A business analyst is comparing used vs. allocated storage cost for each reserved instance on a financial expenditures report related to the cloud. The CSP is currently billing at the following rates for storage:

  $1.50 per GB of used space $0.75 per GB of allocated space The operating expenditures the analyst is reviewing are as follows:

  

  Given this scenario, which of the following servers is costing the firm the least, and which should have storage increased due to over 70% utilization?

  A. Least: File server Optimize: Application server
  B. Least: Application server Optimize: Mail server
  C. Least: Mail server Optimize: File server
  D. Least: Application server Optimize: File server
  D. Least: Application server Optimize: File server

  ---

  Explanation/Reference:

  The least costing server is the application server because it has the lowest used space and allocated space. The file server should have storage increased due to over 70% utilization because it has the highest used space and allocated

  space. To calculate the cost of each server, we can use the following formula:

  Cost = ($1.50 x Used space) + ($0.75 x Allocated space) Using this formula, we can find the cost of each server as follows:

  Application server: Cost = ($1.50 x 186 GB) + ($0.75 x 250 GB) = $279 + $187.50 = $466.50

  Mail server: Cost = ($1.50 x 250 GB) + ($0.75 x 300 GB) = $375 + $225 = $600 File server: Cost = ($1.50 x 450 GB) + ($0.75 x 500 GB) = $675 + $375 = $1050 The application server has the lowest cost of $466.50, while the file server has

  the highest cost of $1050. To find the utilization percentage of each server, we can use the following formula:

  Utilization = (Used space / Allocated space) x 100% Using this formula, we can find the utilization percentage of each server as follows:

  Application server: Utilization = (186 GB / 250 GB) x 100% = 74.4% Mail server: Utilization = (250 GB / 300 GB) x 100% = 83.3% File server: Utilization = (450 GB / 500 GB) x 100% = 90% The file server has the highest utilization percentage

  of 90%, which means that it is running out of storage space and may affect its performance and availability. The application server has the lowest utilization percentage of 74.4%, which means that it has some unused storage space and may

  be overprovisioned. Therefore, the file server should have storage increased to reduce its utilization and improve its efficiency, while the application server is costing the firm the least and does not need any changes in its storage allocation.
