When there is flexibility in when an application needs to run. B. When there are mission-critical workloads. C. When dedicated capacity is needed. D. When an instance should not be stopped. Correct Answer: A Explanation EB1AFA0BAFACF54CCF97159A7B7848C6 Latest IT Certification Practice Exam - Dump4Pass.com Explanation/Reference: Explanation: The key to understanding spot instances is to look at the way that cloud service providers such as Amazon Web Services (AWS) operate. Cloud service providers invest in hardware resources and then release those resources (often on a per-hour basis) to subscribers. One of the problems with this business model, however, is that at any given time, there are likely to be compute resources that are not being utilized. These resources represent hardware capacity that AWS has paid for but are sitting idle, and not making AWS any money at the moment. Rather than allowing these computing resources to go to waste, AWS offers them at a substantially discounted rate, with the understanding that if someone needs those resources for running a normal EC2 instance, that instance will take priority over spot instances that are using the hardware resources at a discounted rate. In fact, spot instances will be stopped if the resources are needed elsewhere.

A. Users bid on the maximum price they are willing to pay per hour. B. Users choose a 1-, 3- or 5-year upfront payment term. C. Users pay for the required permanent storage on a file system or in a database. D D. Users pay based on the number of requests and consumed compute resources. Correct Answer: D Explanation Explanation/Reference: Explanation: AWS Lambda is charging its users by the number of requests for their functions and by the duration, which is the time the code needs to execute. When code starts running in response to an event, AWS Lambda counts a request. It will charge the total number of requests across all of the functions used. Duration is calculated by the time when your code started executing until it returns or until it is terminated, rounded up near to 100ms. The AWS Lambda pricing depends on the amount of memory that the user used to allocate to the function. Reference: https://dashbird.io/blog/aws-lambda-pricing-model-explained/ QUESTION 147 What function do security groups serve related to Amazon Elastic Compute Cloud (Amazon EC2) instance security? EB1AFA0BAFACF54CCF97159A7B7848C6 Latest IT Certification Practice Exam - Dump4Pass.com A. Act as a virtual firewall for the Amazon EC2 instance. B. Secure AWS user accounts with AWS Identity and Access Management (IAM) policies. C. Provide DDoS protection with AWS Shield. D. Use Amazon CloudFront to protect the Amazon EC2 instance. Correct Answer: A Explanation Explanation/Reference: Explanation: AWS Security Groups act like a firewall for your Amazon EC2 instances controlling both inbound and outbound traffic. When you launch an instance on Amazon EC2, you need to assign it to a particular security group. After that, you can set up ports and protocols, which remain open for users and computers over the internet. AWS Security Groups are very flexible. You can use the default security group and still customize it according to your liking (although we don’t recommend this practice because groups should be named according to their purpose.) Or you can create a security group that you want for your specific applications. To do this, you can ss write the corresponding code or use the Amazon EC2 console to make the process easier.

A. Backup and restore B. Pilot light p4 C. Warm standby D. Multi-site active-active Correct Answer: D um Explanation Explanation/Reference: Explanation: Backup and Restore: a simple, straightforward, cost-effective method that backs up and restores data as needed. Keep in mind that because none of your data is on standby, this method, while cheap, can be quite time-consuming. D Pilot Light: This method keeps critical applications and data at the ready so that it can be quickly retrieved if needed. Warm Standby: This method keeps a duplicate version of your business’ core elements running on standby at all times, which makes for a little downtime and an almost seamless transition. Multi-Site Solution: Also known as a Hot Standby, this method fully replicates your company’s data/ applications between two or more active locations and splits your traffic/usage between them. If a disaster strikes, everything is simply rerouted to the unaffected area, which means you’ll suffer almost zero downtime. However, by running two separate environments simultaneously, you will obviously incur much higher costs.

AWS Cost Explorer between AWS accounts B. Linked accounts and consolidated billing C. Amazon Elastic Compute Cloud (Amazon EC2) Reserved Instance Utilization Report ss D. Amazon EC2 Instance Usage Report between AWS accounts Correct Answer: B Explanation Explanation/Reference: Explanation: Pa The way that Reserved Instance discounts apply to accounts in an organization's consolidated billing family depends on whether Reserved Instance sharing is turned on or off for the account. By default, Reserved p4 Instance sharing for all accounts in an organization is turned on. You can change this setting by Turning Off Reserved Instance Sharing for an account. The capacity reservation for a Reserved Instance applies only to the account the Reserved Instance was purchased on, regardless of whether Reserved Instance sharing is turned on or off. um Reference: https://aws.amazon.com/premiumsupport/knowledge-center/ec2-ri-consolidated-billing/ QUESTION 151 A company has multiple AWS accounts and wants to simplify and consolidate its billing process. Which AWS service will achieve this? D A. AWS Cost and Usage Reports B. AWS Organizations C. AWS Cost Explorer D. AWS Budgets Correct Answer: B Explanation Explanation/Reference: Explanation: You can use the consolidated billing feature in AWS Organizations to consolidate billing and payment for multiple AWS accounts or multiple Amazon Internet Services Pvt. Ltd (AISPL) accounts. Every organization in AWS Organizations has a master (payer) account that pays the charges of all the member (linked) accounts.
