How is asset management on AWS easier than asset management in a physical data center?
A. AWS provides a Configuration Management Database that users can maintain.
B. AWS performs infrastructure discovery scans on the customer's behalf.
C. Amazon EC2 automatically generates an asset report and places it in the customer's specified Amazon S3 bucket.
D. Users can gather asset metadata reliably with a few API calls.
Correct Answer: B
AWS assets are centrally managed through an inventory management system that stores and tracks owner, location, status, maintenance, and descriptive information for AWS-owned assets. Following procurement, assets are scanned and tracked, and assets undergoing maintenance are checked and monitored for ownership, status, and resolution.
Which of the following deployment models enables customers to fully trade their capital IT expenses for operational expenses?
A. On-premises
B. Hybrid
C. Cloud
D. Platform as a service
Correct Answer: C
The cloud allows you to trade capital expenses (such as data centers and physical servers) for variable expenses, and only pay for IT as you consume it. Plus, the variable expenses are much lower than what you would pay to do it yourself because of the economies of scale.
A company is designing an application hosted in a single AWS Region serving end-users spread across the world. The company wants to provide the end-users low latency access to the application data. Which of the following services will help fulfill this requirement?
A. Amazon CloudFront
B. AWS Direct Connect
C. Amazon Route 53 global DNS
D. Amazon Simple Storage Service (Amazon S3) transfer acceleration
Correct Answer: B
Use AWS Local Zones to deploy workloads closer to your end-users for low-latency requirements. AWS Local Zones have their own connection to the internet and support AWS Direct Connect, so resources created in the Local Zone can serve local end-users with very low-latency communications.nation
A company has multiple AWS accounts and wants to simplify and consolidate its billing process. Which AWS service will achieve this?
A. AWS Cost and Usage Reports
B. AWS Organizations
C. AWS Cost Explorer
D. AWS Budgets
Correct Answer: B
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.
D. Amazon EC2 Instance Usage Report between AWS accounts
Correct Answer: B
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 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.

your business needs.

Question 1987:
Which disaster recovery scenario offers the lowest probability of down time?
A. Backup and restore
B. Pilot light
C. Warm standby
D. Multi-site active-active
Correct Answer: D
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.
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.
What function do security groups serve related to Amazon Elastic Compute Cloud (Amazon EC2) instance security?
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
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 write the corresponding code or use the Amazon EC2 console to make the process easier.
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. Users pay based on the number of requests and consumed compute resources.
Correct Answer: D
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.
