質問 # 248
What is one benefit AND one drawback of buying a reserved EC2 instance? (Select two) Choose the 2 Correct answers:
- A. Reserved instances can be purchased as a significant discount over on-demand instances.
- B. You are locked in to either a one- or three-year pricing commitment.
- C. You can terminate the instance at any time without any further pricing commitment.
- D. You can potentially save a lot of money by placing a lower "bid" price.
正解：A、B
解説：
Reserved instances require a one- or three-year purchase term, so you are committing to paying for that much compute capacity for that full time period. However, in exchange for the long-term commitment, you will receive a discount (of up to 75%) over using an on-demand instance (for that same time period).

SCPs are a type of policy that specify the maximum permissions for the accounts in your organization, and can help you enforce compliance and security requirements. AWS Organizations also simplifies billing processes by enabling you to consolidate and pay for all member accounts with a single payment method. You can also use AWS Organizations to automate the creation of AWS accounts by using APIs or AWS CloudFormation templates.

質問 # 257
Which of the following are pillars of the AWS Well-Architected Framework? (Select TWO)
- A. Continuous development
- B. Cost optimization
- C. High availability
- D. Going global in minutes
- E. Performance efficiency
正解：B、E
解説：
The AWS Well-Architected Framework is a set of six pillars and lenses that help cloud architects design and run workloads in the cloud. The six pillars are: operational excellence, security, reliability, performance efficiency, cost optimization, and sustainability. Each pillar has a set of design principles and best practices that guide the architectural decisions. High availability is not a separate pillar, but a quality that can be achieved by applying the principles of the reliability pillar. Going global in minutes and continuous development are not pillars of the framework, but possible benefits of using AWS services and following the framework's recommendations.

- A. Network ACLs
- B. AWS Identity and Access Management (1AM)
- C. AWS WAF
- D. Security groups
正解：C
解説：
To allow or block specific IP addresses for your EC2 instances, use a network Access Control List (ACL) or security group rules in your VPC. Network ACLs and security group rules act as firewalls allowing or blocking IP addresses from accessing your resources

質問 # 260
A company wants to receive a notification when a specific AWS cost threshold is reached.
Which AWS services or tools can the company use to meet this requirement? (Select TWO.)
- A. Amazon CloudWatch
- B. Amazon Simple Queue Service (Amazon SQS)
- C. AWS Budgets
- D. AWS Cost and Usage Report
- E. Cost Explorer
正解：A、C
解説：
AWS Budgets and Amazon CloudWatch are two AWS services or tools that the company can use to receive a notification when a specific AWS cost threshold is reached. AWS Budgets allows users to set custom budgets to track their costs and usage, and respond quickly to alerts received from email or Amazon Simple Notification Service (Amazon SNS) notifications if they exceed their threshold. Users can create cost budgets with fixed or variable target amounts, and configure their notifications for actual or forecasted spend. Users can also set up custom actions to run automatically or through an approval process when a budget target is exceeded. For example, users could automatically apply a custom IAM policy that denies them the ability to provision additional resources within an account. Amazon CloudWatch is a service that monitors applications, responds to performance changes, optimizes resource use, and provides insights into operational health. Users can use CloudWatch to collect and track metrics, which are variables they can measure for their resources and applications. Users can create alarms that watch metrics and send notifications or automatically make changes to the resources they are monitoring when a threshold is breached. Users can use CloudWatch to monitor their AWS costs and usage by creating billing alarms that send notifications when their estimated charges exceed a specified threshold amount. Users can also use CloudWatch to monitor their Reserved Instance (RI) or Savings Plans utilization and coverage, and receive notifications when they fall below a certain level.

質問 # 262
A company seeks cost savings in exchange for a commitment to use a specific amount of an AWS service or category ofAWS services for 1 year or 3 years.
Which AWS pricing model or offering will meet these requirements?
- A. Volume discounts
- B. Pay-as-you-go pricing
- C. Savings Plans
- D. AWS Free Tier
正解：C
解説：
Savings Plans are an AWS pricing model or offering that can meet the requirements of seeking cost savings in exchange for a commitment to use a specific amount of an AWS service or category of AWS services for 1 year or 3 years. Savings Plans are flexible plans that offer significant discounts on AWS compute usage, such as EC2, Lambda, and Fargate. The company can choose from two types of Savings Plans: Compute Savings Plans and EC2 Instance Savings Plans. Compute Savings Plans provide the most flexibility and apply to any eligible compute usage, regardless of instance family, size, region, operating system, or tenancy. EC2 Instance Savings Plans provide more savings and apply to a specific instance family within a region. The company can select the amount of compute usage per hour (e.g., $10/hour) that they want to commit to for the duration of the plan (1 year or 3 years). The company will pay the discounted Savings Plan rate for the amount of usage that matches their commitment, and the regular on-demand rate for any usage beyond that

Which AWS hybrid storage service enables your on-premises applications to seamlessly use AWS Cloud storage through standard file-storage protocols?
- A. AWS Direct Connect
- B. AWS Snowball
- C. AWS Snowball Edge
- D. AWS Storage Gateway
正解：D
解説：
Explanation
The AWS Storage Gateway service enables hybrid cloud storage between on-premises environments and the AWS Cloud. It seamlessly integrates on-premises enterprise applications and workflows with Amazon's block and object cloud storage services through industry standard storage protocols. It provides low-latency performance by caching frequently accessed data on premises, while storing data securely and durably in Amazon cloud storage services. It provides an optimized data transfer mechanism and bandwidth management, which tolerates unreliable networks and minimizes the amount of data being transferred. It brings the security, manageability, durability, and scalability of AWS to existing enterprise environments through native integration with AWS encryption, identity management, monitoring, and storage services.
Typical use cases include backup and archiving, disaster recovery, moving data to S3 for in-cloud workloads, and tiered storage.
