CLF-C02 Exam Dumps - AWS Certified Cloud Practitioner

 The correct answer is D because cost allocation tags are a way to track the infrastructure costs for each of the projects separately. Cost allocation tags are key-value pairs that can be attached to AWS resources, such as EC2 instances, and used to categorize and group them for billing purposes. The other options are incorrect because they do not meet the requirements of the question. Use a different EC2 instance type for each project does not help to track the costs for each project, and may impact the performance and compatibility of the applications. Publish project-specific custom Amazon CloudWatch metrics for each application does not help to track the costs for each project, and may incur additional charges for using CloudWatch. Deploy EC2 instances for each project in a separate AWS account does help to track the costs for each project, but it impacts the existing infrastructure and incurs additional charges for using multiple accounts.

 AWS Outposts is a fully managed service that extends AWS infrastructure, AWS services, APIs, and tools to virtually any datacenter, co-location space, or on-premises facility for a truly consistent hybrid experience. AWS Outposts enables you to run AWS services in your on-premises data center1.

The security best practices that should be followed are A and E.

A. Grant the developer access to only the AWS resources needed to perform the job. This is an example of the principle of least privilege, which means giving the minimum permissions necessary to achieve a task. This reduces the risk of unauthorized access, data leakage, or accidental damage to AWS resources.You canuse AWS Identity and Access Management (IAM) to create users, groups, roles, and policies that grant fine-grained access to AWS resources12.

E. Ensure the account password policy requires a minimum length. This is a basic security measure that helps prevent brute-force attacks or guessing of passwords. A longer password is harder to crack than a shorter one.You can use IAM to configure apassword policy that enforces a minimum password length, as well as other requirements such as complexity, expiration, and history34.

B. Share the AWS account root user credentials with the developer. This is a bad practice that should be avoided. The root user has full access to all AWS resources and services, and can perform sensitive actions such as changing billing information, closing the account, or deleting all resources. Sharing the root user credentials exposes your account to potential compromise or misuse.You should never share your root user credentials with anyone, and use them only for account administration tasks5.

C. Add the developer to the administrator’s group in IAM. This is also a bad practice that should be avoided. The administrator’s group has full access to all AWS resources and services, which is more than what a developer needs to perform their job. Adding the developer to the administrator’s group violates the principle of least privilege and increases the risk of unauthorized access, data leakage, or accidental damage to AWS resources.You should create a custom group for the developer that grants only the necessary permissions for their role12.

D. Configure a password policy that ensures the developer’s password cannot be changed. This is another bad practice that should be avoided. Preventing the developer from changing their password reduces their ability to protect their credentials and comply with security policies. For example, if the developer’s password is compromised, they cannot change it to prevent further unauthorized access. Or if the company requires periodic password rotation, they cannot update their password to meet this requirement.You should allow the developer to change their password as needed, and enforce a password policy that sets reasonable rules for password management34.

Amazon ElastiCache is a fully managed in-memory data store service that is compatible with open source engines such as Redis and Memcached1. It provides fast and scalable performance for applications that require high throughput and low latency1. Amazon DynamoDB is a fully managed NoSQL database service that provides consistent and single-digit millisecond latency at any scale2. Amazon EBS is a block storage service that provides persistent and durable storage volumes for Amazon EC2 instances3. Amazon Redshift is a fully managed data warehouse service that allows users to run complex analytic queries using SQL4.

The AWS shared responsibility model describes how AWS and the customer share responsibility for security and compliance of the AWS environment. AWS is responsible for the security of the cloud, which includes the physical security of AWS facilities, the infrastructure, hardware, software, and networking that run AWS services. The customer is responsible for security in the cloud, which includes the configuration of security groups, the encryption of customer data on AWS, the management of AWS Lambda infrastructure, and the management of network throughput of each AWS Region. One of the customer responsibilities is to ensure that Amazon EBS volumes are backed up.

 The correct answers are B and E because AWS Online Tech Talks and AWS Classroom Training are options that AWS makes available for customers who want to learn about security in the cloud in an instructor-led setting. AWS Online Tech Talks are live, online presentations that cover a broad range of topics at varying technical levels. AWS Online Tech Talks are delivered by AWS experts and feature live Q&A sessions with the audience. AWS Classroom Training are in-person or virtual courses that are led by accredited AWS instructors. AWS Classroom Training offer hands-on labs, exercises, and best practices to help customers gain confidence and skills on AWS. The other options are incorrect because they are not options that AWS makes available for customers who want to learn about security in the cloud in an instructor-led setting. AWS Trusted Advisor is an AWS service that provides real-time guidance to help customers follow AWS best practices for security, performance, cost optimization, and fault tolerance. AWS Blog is an AWS resource that provides news, announcements, and insights from AWS experts and customers. AWS Forums are AWS resources that enable customers to interact with other AWS users and get feedback and support. Reference: AWS Online Tech Talks, AWS Classroom Training

Security groups are the AWS service or feature that can be used to apply security rules to specific Amazon EC2 instances. Security groups are virtual firewalls that control the inbound and outbound traffic for one or more instances. Customers can create security groups and add rules that reflect the role of the instance that is associated with the security group. For example, a web server instance needs security group rules that allow inbound HTTP and HTTPS access, while a database instance needs rules that allow access for the type of database12. Security groups are stateful, meaning that the responses to allowed inbound traffic are alsoallowed, regardless of the outbound rules1. Customers can assign multiple security groups to an instance, and the rules from each security group are effectively aggregated to create one set of rules1.

Network ACLs are another AWS service or feature that can be used to control the traffic for a subnet. Network ACLs are stateless, meaning that they do not track the traffic that they allow. Therefore, customers must add rules for both inbound and outbound traffic3. Network ACLs are applied at the subnet level, not at the instance level.

AWS Trusted Advisor is an AWS service that provides best practice recommendations for security, performance, cost optimization, and fault tolerance. AWS Trusted Advisor does not apply security rules to specific Amazon EC2 instances, but it can help customers identify security gaps and improve their security posture4.

AWS WAF is an AWS service that helps protect web applications from common web exploits, such as SQL injection, cross-site scripting, and bot attacks. AWS WAF does not apply security rules to specific Amazon EC2 instances, but it can be integrated with other AWS services, such as Amazon CloudFront, Amazon API Gateway, and Application Load Balancer.

Amazon RDS is the AWS service that will meet the requirements of migrating a relational database server to the AWS Cloud and minimizing administrative overhead of database maintenance tasks. Amazon RDS is a fully managed relational database service that handles routine database tasks, such as provisioning, patching, backup, recovery, failure detection, and repair. Amazon RDS supports several database engines, such as MySQL, PostgreSQL, Oracle, SQL Server, and Amazon Aurora5.
