- A. Hybrid
- B. Lift and shift
- C. Phased
- D. Rip and replace
正解：B
解説：
A lift and shift migration approach is the best option for a company that needs to move rapidly to a cloud environment. A lift and shift migration, also known as rehosting, involves moving an existing application and its associated data to a cloud platform without changing the app's architecture. This approach is suitable for applications that are compatible with the cloud provider's infrastructure and do not require significant modifications or optimizations to run in the cloud. A lift and shift migration can offer the following benefits for a company that needs to move quickly to the cloud:
質問 # 51
A company with a variable number of employees would make good use of the cloud model because of:
- A. subscription services
- B. collaboration
- C. multifactor authentication
- D. self-service
正解：A
解説：
A company with a variable number of employees would make good use of the cloud model because of subscription services. Subscription services are a type of cloud pricing model that allows customers to pay a fixed fee for a certain amount of cloud resources or services for a specific period of time, such as monthly or annually. Subscription services can offer benefits such as predictable costs, scalability, flexibility, and reduced upfront investment. A company with a variable number of employees can use subscription services to adjust the cloud resources or services according to the changing demand and size of the workforce, without wasting money on unused capacity or paying extra fees for exceeding the limit. Subscription services can also enable the company to access the latest cloud technologies and features without having to purchase or maintain them. The other options are not the best reasons for a company with a variable number of employees to use the cloud model. Multifactor authentication is a security method that requires users to provide two or more pieces of evidence to verify their identity, such as a password, a code, or a biometric factor. Multifactor authentication can enhance the security of the cloud services, but it is not related to the number of employees. Self-service is a cloud characteristic that allows users to provision, manage, and terminate cloud resources or services on demand, without requiring the intervention of the cloud provider or the IT department. Self-service can improve the efficiency and agility of the cloud services, but it is not related to the number of employees. Collaboration is a cloud benefit that enables users to work together on projects, documents, or tasks using cloud-based tools and platforms, such as online file sharing, video conferencing, or project management. Collaboration can increase the productivity and innovation of the cloud services, but it is not related to the number of employees.

質問 # 52
Which of the following is MOST likely to use a CDN?
- A. Email service provider
- B. Realty listing website
- C. Document management system
- D. Video streaming service
正解：D
解説：
A CDN (content delivery network) is a network of distributed servers that store and deliver content to users based on their geographic location and network conditions. A CDN can improve the performance, availability, scalability, and security of web-based applications and services by reducing the latency, bandwidth, and load on the origin server. A CDN is most likely to be used by a video streaming service, which typically involves large amounts of data, high demand, and diverse audiences. A video streaming service can benefit from using a CDN by caching and streaming the video content from the nearest or best-performing server to the user, thus enhancing the user experience and reducing the cost and complexity of the service.
A realty listing website is a web-based application that allows users to search, view, and compare properties for sale or rent. A realty listing website may use a CDN to improve the performance and availability of the website, especially if it has a large number of images, videos, or other media files. However, a realty listing website is not as likely to use a CDN as a video streaming service, since the content is not as dynamic, the demand is not as high, and the audience is not as diverse.
An email service provider is a company that offers email hosting, management, and delivery services to users. An email service provider may use a CDN to improve the security and reliability of the email service, especially if it has a large number of users, messages, or attachments. However, an email service provider is not as likely to use a CDN as a video streaming service, since the content is not as public, the performance is not as critical, and the location is not as relevant.
A document management system is a software application that allows users to create, store, organize, and share documents. A document management system may use a CDN to improve the scalability and accessibility of the document storage and retrieval, especially if it has a large number of documents, users, or collaborators. However, a document management system is not as likely to use a CDN as a video streaming service, since the content is not as large, the demand is not as variable, and the audience is not as global.

Which of the following cloud computing characteristics would BEST address the issue?
- A. Availability
- B. Self-service
- C. Pay-as-you-go
- D. Elasticity
正解：D
解説：
Elasticity is the cloud computing characteristic that allows the cloud service to scale up or down the resources dynamically according to the demand. Elasticity can help the organization address the issue of performance degradation from oversubscription of memory in the virtual environment and exhausted physical RAM by automatically allocating more memory resources to the servers when needed and releasing them when not needed. This way, the organization can avoid the risk of running out of memory and ensure optimal performance of the servers.

A systems administrator needs to transfer 300GB of data to the cloud every month. Given the information below:
Which of the following connection methods would be the MOST cost-effective and satisfy the monthly transfer requirements?
- A. Enhanced Direct Connect (1GB)
- B. Enhanced VPN (200MB)
- C. VPN (100MB)
- D. Direct Connect (500MB)
正解：D
解説：
According to the CompTIA Cloud Essentials objectives and documents, the most cost-effective and satisfying monthly transfer requirements connection method would be Direct Connect (500MB). This is because it has a fixed cost of $200 per month and a transfer limit of up to
250GB, which is enough to satisfy the 300GB monthly transfer requirement. Additionally, it has a lower cost per GB after the transfer limit is reached compared to the other options. The other connection methods are either more expensive or insufficient for the monthly transfer requirement. VPN (100MB) has a fixed cost of $50 per month and a transfer limit of up to 50GB, which is not enough for the 300GB monthly transfer requirement. Enhanced VPN (200MB) has a fixed cost of $100 per month and a transfer limit of up to 100GB, which is also not enough for the
300GB monthly transfer requirement. Enhanced Direct Connect (1GB) has a fixed cost of $400 per month and a transfer limit of up to 500GB, which is more than enough for the 300GB monthly transfer requirement, but also more expensive than Direct Connect (500MB).
質問 # 61
A company is migrating an application to a cloud hosting platform and needs GUI-based server access to install applications. Which of the following would be the BEST solution for the company?
- A. HTTPS
- B. RDP
- C. SFTP
- D. SSH
正解：B
解説：
RDP (Remote Desktop Protocol) is a protocol that allows a user to remotely access and control a graphical user interface (GUI) of another computer over a network. RDP can be used to install applications, configure settings, and perform administrative tasks on a cloud-hosted server. RDP is supported by Windows-based operating systems and some Linux distributions. RDP can also be accessed by using third-party software or web browsers. RDP provides a secure and encrypted connection between the client and the server, and supports features such as audio, video, clipboard, printer, and file sharing. RDP would be the best solution for a company that needs GUI-based server access to migrate an application to a cloud hosting platform.

質問 # 66
A company's finance team is reporting increased cloud costs against the allocated cloud budget. Which of the following is the BEST approach to match some of the cloud operating costs with the appropriate departments?
- A. Scaling
- B. Right-sizing
- C. Showback
- D. Chargeback
正解：D
解説：
Chargeback is the best approach to match some of the cloud operating costs with the appropriate departments. Chargeback is a process where the IT department bills each department for the amount of cloud resources they use, such as compute, storage, network, or software. Chargeback can help the company to allocate the cloud costs more accurately and fairly, as well as to encourage the departments to optimize their cloud consumption and reduce waste. Chargeback can also provide the company with more visibility and accountability of the cloud usage and spending across the organization12 Chargeback is different from showback, which is a process where the IT department shows each department the amount of cloud resources they use, but does not charge them for it. Showback can also help the company to increase the awareness and transparency of the cloud costs, but it may not have the same impact on the behavior and efficiency of the departments as chargeback12 Right-sizing and scaling are not approaches to match the cloud costs with the departments, but rather techniques to adjust the cloud resources to the actual demand and performance of the applications or services. Right-sizing and scaling can help the company to save money and improve the cloud utilization, but they do not address the issue of cost allocation or attribution34

質問 # 68
Which of the following explains why a cloud provider would establish and publish a format data sanitization policy for its clients?
- A. To ensure clients feel comfortable about the handling of any leftover data after termination of the contract
- B. To provide a value add for clients that will assist in cleansing records at no additional charge
- C. To establish guidelines for how the provider will cleanse any data being imported during a cloud migration
- D. To be transparent about how the CSP will handle malware infections that may impact systems housing client data
正解：A
解説：
A data sanitization policy is a document that defines how a cloud service provider (CSP) will permanently delete or destroy any data that belongs to its clients after the termination of the contract or the deletion of the service. Data sanitization is a process that ensures that the data is not recoverable by any means, even by advanced forensic tools. Data sanitization is important for cloud security and privacy, as it prevents unauthorized access, disclosure, or misuse of the data by the CSP or any third parties. A data sanitization policy can help the CSP demonstrate its compliance with the data protection laws and regulations, such as the General Data Protection Regulation (GDPR) or the Health Insurance Portability and Accountability Act (HIPAA), that may apply to its clients' data. A data sanitization policy can also help the CSP build trust and confidence with its clients, as it assures them that their data will be handled securely and responsibly, and that they will have full control and ownership of their data. Therefore, option D is the best explanation of why a cloud provider would establish and publish a format data sanitization policy for its clients. Option A is incorrect because it does not explain why a cloud provider would establish and publish a format data sanitization policy for its clients, but rather how the provider will cleanse any data being imported during a cloud migration. Data cleansing is a process that improves the quality and accuracy of the data by removing or correcting any errors, inconsistencies, or duplicates. Data cleansing is not the same as data sanitization, as it does not involve deleting or destroying the data. Option B is incorrect because it does not explain why a cloud provider would establish and publish a format data sanitization policy for its clients, but rather how the CSP will handle malware infections that may impact systems housing client data. Malware is a malicious software that can harm or compromise the systems or data of the CSP or its clients. Malware prevention and detection are important aspects of cloud security, but they are not the same as data sanitization, as they do not involve deleting or destroying the data. Option C is incorrect because it does not explain why a cloud provider would establish and publish a format data sanitization policy for its clients, but rather how the CSP will provide a value add for clients that will assist in cleansing records at no additional charge. Data cleansing, as explained above, is a process that improves the quality and accuracy of the data, not a process that deletes or destroys the data. Data cleansing may or may not be offered by the CSP as a value-added service, but it is not the same as data sanitization, which is a mandatory and essential service for cloud security and privacy.

- C. Insist that the provider implement username/password on all protocols.
- D. Insist that the provider place firewalls and routers at the border of the cloud environment.
正解：B
質問 # 71
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. VDI
- B. SSH
- C. VPN
- D. SSO
正解：A
解説：
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.
