Which task can an IAM user perform without AWS account root user credentials?
IAM Users and Billing Permissions:
IAM users with appropriate permissions can access and view the AWS Billing console.
The root user is required only for certain account-level tasks, such as changing support plans or closing accounts.
Why Other Options Are Incorrect:
A . Change to a different AWS Support plan: Requires root user credentials.
B . Close an AWS account: Requires root user credentials.
D . Activate access to the AWS Billing console: Requires root user credentials.
A company notices suspicious network activity against an application that is running on a fleet of Amazon EC2 instances. The suspicious activity is coming from a single IP address.
Which AWS service should the company use to block access from this IP address?
AWS WAF Overview:
AWS Web Application Firewall (WAF) allows users to create rules to block or allow traffic based on IP addresses, request patterns, and other conditions.
It is ideal for blocking traffic from a specific IP address.
Why AWS WAF Meets the Requirement:
The company can create a WAF rule to block traffic from the malicious IP address.
WAF integrates with services like Amazon CloudFront, Application Load Balancer, and API Gateway.
Why Other Options Are Incorrect:
A . AWS Shield: Protects against DDoS attacks but does not allow custom IP blocking.
B . AWS Config: Monitors resource configurations but does not block IPs.
C . Amazon GuardDuty: Detects threats but does not block traffic directly.
A company purchased Amazon EC2 Standard Reserved Instances (Rls) for a workload in the AWS Cloud. The company needs to move part of the workload to an instance family that does not match the instance family of these Standard RIs.
How can the company take advantage of the Standard RIs that it no longer needs?
The Amazon EC2 Reserved Instance Marketplace allows customers to sell unused Standard Reserved Instances to other AWS users. This enables companies to recoup some of the costs if they no longer need certain RIs. Standard RIs cannot be converted to Savings Plans, and AWS Support does not facilitate the resale of RIs directly.
A company needs to store infrequently used data for data archives and long-term backups.
Which AWS service or storage class will meet these requirements MOST cost-effectively?
Amazon S3 Glacier Flexible Retrieval is optimized for storing infrequently accessed data at a very low cost, making it suitable for data archiving and long-term backups. It provides flexible retrieval options for archived data. Other services like FSx for Lustre, EBS, and EFS are more suited for frequently accessed data and higher-performance use cases, not archival storage.
A company is releasing a business-critical application. Before the release, the company needs strategic planning assistance from AWS. During the release, the company needs AWS infrastructure event management and real-time support.
What should the company do to meet these requirement?
AWS Enterprise Support provides strategic planning assistance, infrastructure event management, and real-time support, which are necessary for business-critical applications. Trusted Advisor and APN do not offer direct strategic support, and while AWS Professional Services can assist with complex solutions, Enterprise Support specifically includes ongoing operational support and event management.
