Which of the following are characteristics of AWS WAF? (Select TWO.)
A. Acts as a firewall that controls inbound and outbound traffic between Amazon EC2 instances
B. Acts as a firewall that controls inbound and outbound traffic between subnets
C. Gives users the ability to block traffic that has specific HTTP headers
D. Protects websites that are not hosted on AWS
E. Scans Amazon EC2 instances for common vulnerabilities
Answer: BC
Explanation:
AWS WAF lets you create rules to filter web traffic based on conditions that include IP addresses, HTTP headers and body, or custom URIs. This gives you an
additional layer of protection from web attacks that attempt to exploit vulnerabilities in custom or third party web applications. In addition, AWS WAF makes it easy
to create rules that block common web exploits like SQL injection and cross site scripting.
AWS WAF allows you to create a centralized set of rules that you can deploy across multiple websites. This means that in an environment with many websites and
web applications you can create a single set of rules that you can reuse across applications rather than recreating that rule on every application you want to
protect.
NEW QUESTION 10
- (Exam Topic 1)
A company requires an isolated environment within AWS for security purposes. Which action can be taken to accomplish this?
Answer: B
Explanation:
Network isolation A virtual private cloud (VPC) is a virtual network in your own logically isolated area in the AWS Cloud. Use separate VPCs to isolate
infrastructure by workload or organizational entity. A subnet is a range of IP addresses in a VPC. When you launch an instance, you launch it into a subnet in your
VPC. Use subnets to isolate the tiers of your application (for example, web, application, and database) within a single VPC. Use private subnets for your instances
if they should not be accessed directly from the internet. To call the Amazon EC2 API from your VPC without sending traffic over the public internet, use AWS
PrivateLink. https://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/infrastructure-security.html

How does consolidated billing help reduce costs for a company that has multiple AWS accounts?
A. It aggregates usage across accounts so that the company can reach volume discount thresholds sooner.
B. It offers an additional 5% discount on purchases of All Upfront Reserved Instances.
C. It provides a simplified billing invoice that the company can process more quickly than a standard invoice.
D. It gives AWS resellers the ability to bill their customers for usage.
Answer: A
Explanation:
Consolidated billing for AWS Organizations
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 management account that pays the charges of all the member accounts. For
more information about organizations, see the AWS Organizations User Guide.
Consolidated billing has the following benefits:
*One bill – You get one bill for multiple accounts.
*Easy tracking – You can track the charges across multiple accounts and download the combined cost and usage data.
*Combined usage – You can combine the usage across all accounts in the organization to share the volume pricing discounts, Reserved Instance discounts, and
Savings Plans. This can result in a lower charge for your project, department, or company than with individual standalone accounts. For more information, see
Volume discounts.
*No extra fee – Consolidated billing is offered at no additional cost. Note:
The member account bills are for informational purpose only. The management account might reallocate the additional volume discounts, Reserved Instance, or
Savings Plans discounts that your account receives.
If you have access to the management account, you can see a combined view of the AWS charges that the member accounts incur. You also can get a cost report
for each member account.
AWS and AISPL accounts can't be consolidated together. If your contact address is in India, you can use AWS Organizations to consolidate AISPL accounts within
your organization.
Important
When a member account leaves an organization, the member account can no longer access Cost Explorer data that was generated when the account was in the
organization. The data isn't deleted, and the management account in the organization can still access the data. If the member account rejoins the organization, the
member account can access the data again.

Which AWS service or feature will meet these requirements?
Answer: D
Explanation:
AWS Key Management Service (AWS KMS) makes it easy for you to create and manage cryptographic keys and control their use across a wide range of AWS
services and in your applications. AWS KMS is a secure and resilient service that uses hardware security modules that have been validated under FIPS 140-2, or
are in the process of being validated, to protect your keys. AWS KMS is integrated with AWS CloudTrail to provide you with logs of all key usage to help meet your
regulatory and compliance needs.

posture across all of your AWS accounts.
Answer: A
Answer: C
Explanation:
https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html
Where possible, we recommend relying on temporary credentials instead of creating long-term credentials such as access keys. However, for scenarios in which
you need IAM users with programmatic access and long-term credentials, we recommend that you rotate access keys. Regularly rotating long-term credentials
helps you familiarize yourself with the process. This is useful in case you are ever in a situation where you must rotate credentials, such as when an employee
leaves your company. We recommend that you use IAM access last used information to rotate and remove access keys safely.

Answer: D
Explanation:
Reliability Scale horizontally to increase aggregate workload availability: Replace one large resource with multiple small resources to reduce the impact of a single
failure on the overall workload. Distribute requests across multiple, smaller resources to ensure that they don’t share a common point of failure. Stop guessing
capacity: A common cause of failure in on-premises workloads is resource saturation, when the demands placed on a workload exceed the capacity of that
workload (this is often the objective of denial of service attacks).
