• Question 181:

  A business analyst is drafting a proposal for eliminating redundant copies of data from a SAN disk drive. Which of the following terms should the analyst mention in the proposal?

  A. Deduplication
  B. Encryption
  C. Sanitization
  D. Compression
  A. Deduplication

  ---

  Explanation/Reference:

  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.

• Question 182:

  A cloud administrator suggested using spot instances to reduce cloud costs for part of a new cloud infrastructure.

  Which of the following conditions must be addressed by the application that will run on these instances?

  A. The application needs to store data in a database.
  B. There is a restriction for distributed network communications.
  C. The application needs to handle unpredictable instance termination.
  D. Resource-intensive compute loads will be forbidden.
  C. The application needs to handle unpredictable instance termination.

  ---

  Explanation/Reference:

  Spot instances are cloud resources that are available at a lower price than on-demand instances, but can be terminated by the cloud provider at any time based on supply and demand. Therefore, the application that will run on these instances needs to handle unpredictable instance termination, such as by saving state information, implementing fault tolerance, or using checkpoints12. The other options are not directly related to the use of spot instances. The application may or may not need to store data in a database, depending on its functionality and design. There is no inherent restriction for distributed network communications when using spot instances, as long as the application can handle network latency and bandwidth issues. Resource-intensive compute loads are not forbidden, but they may increase the likelihood of instance termination, as the cloud provider may reclaim the resources for higher-paying customers.

• Question 183:

  A low-budget project with a flexible completion time can become financially feasible via the use of:

  A. right-sizing.
  B. resource tagging.
  C. reserved instances.
  D. spot instances.
  D. spot instances.

  ---

  Explanation/Reference:

  Spot instances are instances that use spare cloud capacity that is available for less than the On-Demand price. They are suitable for low-budget projects that can tolerate interruptions and have flexible completion time. Spot instances can be reclaimed by the cloud provider when the demand for the capacity increases, so they are not guaranteed to run continuously. However, they can offer significant cost savings compared to other pricing models.

• Question 184:

  Which of the following technologies would help a game company prepare its cloud infrastructure to support a global distribution workload of a newly released online game? (Choose two.)

  A. Auto-scaling
  B. VDI
  C. Data portability
  D. CDN
  E. Templates
  F. Blockchain
  A. Auto-scaling
  D. CDN

  ---

  Explanation/Reference:

  Auto-scaling and CDN are two technologies that would help a game company prepare its cloud infrastructure to support a global distribution workload of a newly released online game. Auto-scaling is the ability of a cloud service to automatically adjust the amount of resources, such as compute, storage, or bandwidth, based on the demand or load of the service. Auto-scaling can help a game company to handle the spikes or fluctuations in the number of players or traffic that may occur during the launch or peak times of a new online game. Auto-scaling can also help the game company to optimize the performance, availability, and cost of the cloud service, as it can scale up or down the resources as needed. Auto-scaling can be triggered by predefined rules, metrics, or schedules, or by using machine learning or artificial intelligence to predict the demand patterns12 CDN stands for Content Delivery Network, which is a network of distributed servers that deliver content, such as web pages, images, videos, or games, to the end-users based on their geographic location, the origin of the content, and the network conditions. CDN can help a game company to distribute its online game to a global audience, as it can reduce the latency, bandwidth, and load on the origin server, and improve the user experience, security, and reliability of the content delivery. CDN can also help the game company to cope with the high volume of requests or traffic that may occur during the launch or peak times of a new online game. CDN can use various techniques, such as caching, compression, encryption, or load balancing, to optimize the content delivery34 References: CompTIA Cloud Essentials+ Certification Exam Objectives5, CompTIA Cloud Essentials+ Study Guide, Chapter 4: Cloud Storage6, Chapter 6: Cloud Connectivity and Load Balancing7

• Question 185:

  A Chief Information Officer (CIO) wants to identify two business units to be pilots for a new cloud project. A business analyst who was recently assigned to this project will be selecting a cloud provider. Which of the following should the business analyst do FIRST?

  A. Conduct a feasibility study of the environment.
  B. Conduct a benchmark of all major systems.
  C. Draw a matrix diagram of the capabilities of the cloud providers.
  D. Gather business and technical requirements for key stakeholders.
  D. Gather business and technical requirements for key stakeholders.

  ---

  Explanation/Reference:

  The first step for the business analyst to select a cloud provider for the new cloud project is to gather business and technical requirements for key stakeholders. Business requirements are the needs and expectations of the business units and end users, such as the goals, benefits, and outcomes of the project. Technical requirements are the specifications and constraints of the cloud solution, such as the performance, availability, security, and scalability. Gathering business and technical requirements is essential to understand the scope, objectives, and criteria of the project, and to evaluate and compare different cloud providers based on their capabilities and offerings1. Conducting a feasibility study of the environment is a possible next step after gathering the requirements, to assess the viability and suitability of the cloud project, and to identify the risks, costs, and benefits of moving to the cloud2. Conducting a benchmark of all major systems is another possible step after gathering the requirements, to measure the current performance and utilization of the existing systems, and to determine the optimal configuration and resources for the cloud solution3. Drawing a matrix diagram of the capabilities of the cloud providers is a possible step after gathering the requirements and conducting the feasibility study and the benchmark, to compare and contrast the features and services of different cloud providers, and to select the best fit for the project4.

• Question 186:

  The Chief Financial Officer for a company that operates a popular SaaS application has noticed compute costs from the CSP are extremely high but storage costs are relatively low. Which of the following does the company MOST likely operate?

  A. An email application
  B. A CDN service
  C. A gaming application
  D. Audio streaming service
  C. A gaming application

  ---

  Explanation/Reference:

  A gaming application is a type of SaaS application that requires high compute resources to run the game logic, graphics, physics, and networking. Gaming applications also need to handle a large number of concurrent users and provide low latency and high performance. Therefore, the compute costs from the CSP would be extremely high for a gaming application. On the other hand, a gaming application does not need much storage space, as most of the game data is stored on the client side or in memory. Therefore, the storage costs from the CSP would be relatively low for a gaming application. The other options are not likely to have high compute costs and low storage costs. An email application, a CDN service, and an audio streaming service all need to store large amounts of data on the cloud, which would increase the storage costs. An email application and a CDN service do not need much compute power, as they mainly involve sending and receiving data. An audio streaming service may need some compute power to process and encode the audio files, but not as much as a gaming application. Therefore, the correct answer is C. A gaming application.

  Explanation/Reference:

  Encryption in transit is the process of protecting data from unauthorized access or modification while it is being transferred from one location to another, such as from an on-premises data center to a cloud service provider. Encryption in transit uses cryptographic techniques to scramble the data and make it unreadable to anyone who intercepts it, except for the intended recipient who has the key to decrypt it. Encryption in transit is one of the best approaches to optimize data security in an IaaS migration, as it reduces the risk of data breaches, tampering, or leakage during the data transfer. Encryption in transit can be implemented using various methods, such as Transport Layer Security (TLS), Secure Sockets Layer (SSL), Internet Protocol Security (IPsec), or Secure Shell (SSH). Encryption in transit is different from other options, such as reviewing the risk register, performing a vulnerability scan, or performing server hardening. Reviewing the risk register is the process of identifying, analyzing, and prioritizing the potential threats and impacts to the data and the cloud environment. Performing a vulnerability scan is the process of detecting and assessing the weaknesses or flaws in the data and the cloud infrastructure that could be exploited by attackers. Performing server hardening is the process of applying security measures and configurations to the cloud servers to reduce their attack surface and improve their resilience. While these options are also important for data security, they do not directly address the data protection during the migration process, which is the focus of the question.

• Question 188:

  Which of the following concepts is the backup and recovery of data considered?

  A. Risk avoidance
  B. Confidentiality
  C. Integrity
  D. Availability
  D. Availability

  ---

  Explanation/Reference:

  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.

• Question 189:

  A company would like to improve its current DR plan with an emphasis on high availability. Which of the following metrics should the company focus on?

  A. MTTR
  B. RTO
  C. QoS
  D. RPO
  B. RTO

  ---

  Explanation/Reference:

  A company that would like to improve its current disaster recovery (DR) plan with an emphasis on high availability should focus on the metrics of recovery time objective (RTO) and recovery point objective (RPO). RTO is the maximum duration of time that a system or service can be unavailable after a disaster or disruption before the business suffers unacceptable consequences. RPO is the maximum amount of data loss that a system or service can tolerate in a disaster or disruption before the business suffers unacceptable consequences. Both RTO and RPO measure the impact of downtime on the business and help determine the appropriate recovery strategies and solutions. High availability requires low RTO and RPO values, which means that the system or service should be restored quickly and with minimal data loss in case of a disaster or disruption.

• Question 190:

  A company wants to analyze the results of an email marketing campaign. The company identified different information sources it can use in combination with its current databases. It also contacted the CSP to use its solutions to ingest, transform, and process the information. Which of the following is the company implementing?

  A. Blockchain
  B. Big Data
  C. Social media
  D. loT
  B. Big Data

  ---

  Explanation/Reference:

  Big data is a term that describes the large and diverse datasets that are generated from various sources at high speed and require advanced analytics techniques to process and extract value from them. Big data can help organizations gain insights, uncover patterns, and make informed decisions12 The company is implementing big data because it is using different information sources in combination with its current databases, which implies that the data is large in volume and variety. The company is also using the CSP's solutions to ingest, transform, and process the information, which implies that the data is high in velocity and requires specialized tools and frameworks to handle it. The company is using big data analytics to analyze the results of its email marketing campaign, which can help it understand the effectiveness, impact, and return on investment of its marketing strategy34 Blockchain is not the correct answer, because blockchain is a technology that enables the creation and management of distributed, decentralized, and immutable ledgers of transactions. Blockchain can help organizations improve transparency, security, and trust in their business processes, but it is not related to the analysis of email marketing campaign results. Social media is not the correct answer, because social media is a platform that enables the creation and sharing of content and information among users. Social media can help organizations communicate, engage, and interact with their customers, but it is not the main focus of the analysis of email marketing campaign results. Social media can be one of the information sources for big data, but it is not the same as big data. IoT is not the correct answer, because IoT is a concept that refers to the network of physical devices, sensors, and machines that are connected to the internet and can collect and exchange data. IoT can help organizations improve efficiency, productivity, and innovation, but it is not related to the analysis of email marketing campaign results. IoT can be one of the information sources for big data, but it is not the same as big data.
