問題 #219
A user would like a removable storage device that is secure. portable, and does not contain moving parts.
Which of the following devices would be the most suitable?

A. HDD
B. NAS
C. SAN
D. SSD

答案：D

解題說明：
Explanation
An SSD (solid state drive) is a removable storage device that uses flash memory to store data. It is secure, portable, and does not contain moving parts, which makes it more reliable and durable than other types of storage devices. An HDD (hard disk drive) is not suitable, as it contains spinning platters and read/write heads that are prone to damage and data loss. A NAS (network attached storage) and a SAN (storage area network) are not removable devices, as they are connected to a network and provide shared storage for multiple users.

問題 #220
Which of the following models is an example of metered utilization?

A. Pay-as-you-go
B. Multitenant
C. Reserved instance
D. Subscription-based

答案：A

解題說明：
Metered utilization is a pricing model for cloud computing services, where the customer pays only for the amount of resources that are consumed, such as CPU time, memory, storage, bandwidth, etc. The customer is billed based on the actual usage of the resources, rather than a fixed or upfront fee. Metered utilization is also known as usage-based pricing or pay-per-use12.
Pay-as-you-go is an example of metered utilization, where the customer pays for the cloud resources on demand, without any long-term commitment or contract. The customer can scale up or down the resources as needed, and only pay for what is used. Pay-as-you-go is a flexible and cost-effective option for customers who have unpredictable or variable workloads, or who want to try out new services or features12.
The other options are not examples of metered utilization. Reserved instance is a pricing model where the customer pays a discounted rate for a fixed amount of cloud resources for a specified period of time, such as one or three years. The customer can reserve the resources in advance, and benefit from lower costs and guaranteed availability. Reserved instance is suitable for customers who have predictable or steady workloads, or who want to optimize their budget12.
Subscription-based is a pricing model where the customer pays a fixed fee for a set of cloud services or features for a certain period of time, such as monthly or annually. The customer can access the services or features as much as needed, without worrying about the usage or consumption of the resources. Subscription-based is suitable for customers who want to have a consistent and predictable cost, or who want to access premium or exclusive services or features12.
Multitenant is not a pricing model, but a cloud architecture where multiple customers share the same physical or virtual resources, such as servers, databases, applications, etc. The resources are isolated and secured for each customer, and the customers can benefit from lower costs, higher scalability, and faster updates. Multitenant is a common characteristic of public cloud services, where the cloud provider manages and maintains the resources for the customers12.

問題 #221
An organization maintains various record types, including health and criminal justice records. Which of the following cloud environments is the organization MOST likely to use to limit the attack surface?

A. Community
B. Hybrid
C. Private
D. Public

答案：C

解題說明：
Private cloud environments are designed for use by a single organization and offer the greatest control over security and access to data. They are typically used for sensitive or confidential data, such as health and criminal justice records. Public cloud environments are shared by multiple organizations and offer less control over security and access to data. Hybrid cloud environments combine public and private clouds, while community clouds are shared by multiple organizations with similar needs.

問題 #222
Which of the following is used primarily for archiving data?

A. WAN
B. MAN
C. SAN
D. LAN
E. PAN

答案：C

解題說明：
A Storage Area Network (SAN) is primarily used for data archiving and large-scale storage. SANs provide high-speed, block-level storage for enterprise environments.
* Why Not A (PAN): Personal Area Networks are for connecting personal devices like phones and smartwatches.
* Why Not B (MAN): Metropolitan Area Networks are for city-wide data communication, not storage.
* Why Not D (LAN): Local Area Networks are for general connectivity, not dedicated storage.
* Why Not WAN: Wide Area Networks are for connecting geographically dispersed networks, not storage.
