Amazon AWS Certified Solutions Architect - Associate Sample Questions (Q841-Q846):

NEW QUESTION # 841
To meet security requirements, a company needs to encrypt all of its application data in transit while communicating with an Amazon RDS MySQL DB instance. A recent security audit revealed that encryption at rest is enabled using AWS Key Management Service (AWS KMS), but data in transit is not enabled.
What should a solutions architect do to satisfy the security requirements?

A. Enable 1AM database authentication on the database.
B. Provide self-signed certificates. Use the certificates in all connections to the RDS instance.
C. Take a snapshot of the RDS instance. Restore the snapshot to a new instance with encryption enabled.
D. Download AWS-provided root certificates. Provide the certificates in all connections to the RDS instance.

Answer: D

Explanation:
To satisfy the security requirements, the solutions architect should download AWS-provided root certificates and provide the certificates in all connections to the RDS instance. This will enable SSL/TLS encryption for data in transit between the application and the RDS instance. SSL/TLS encryption provides a layer of security by encrypting data that moves between the client and the server. Amazon RDS creates an SSL certificate and installs the certificate on the DB instance when the instance is provisioned. The application can use the AWS-provided root certificates to verify the identity of the DB instance and establish a secure connection1.
The other options are not correct because they do not enable encryption for data in transit or are not relevant for the use case. Enabling IAM database authentication on the database is not correct because this option only provides a method of authentication, not encryption. IAM database authentication allows users to use AWS Identity and Access Management (IAM) users and roles to access a database, instead of using a database user name and password2. Providing self-signed certificates is not correct because this option is not secure or reliable. Self-signed certificates are certificates that are signed by the same entity that issued them, instead of by a trusted certificate authority (CA). Self-signed certificates can be easily forged or compromised, and are not recognized by most browsers and applications3. Taking a snapshot of the RDS instance and restoring it to a new instance with encryption enabled is not correct because this option only enables encryption at rest, not encryption in transit. Encryption at rest protects data that is stored on disk, but does not protect data that is moving between the client and the server4.

NEW QUESTION # 842
A company uses Amazon EC2 instances to host its internal systems. As part of a deployment operation, an administrator tries to use the AWS CLI to terminate an EC2 instance. However, the administrator receives a
403 (Access Denied) error message.
The administrator is using an IAM role that has the following IAM policy attached:

What is the cause of the unsuccessful request?

A. The request to terminate the EC2 instance does not originate from the CIDR blocks 192.0.2.0/24 or
203.0 113.0/24
B. The EC2 instance has a resource-based policy with a Deny statement.
C. The principal has not been specified in the policy statement
D. The "Action" field does not grant the actions that are required to terminate the EC2 instance.

Answer: A

NEW QUESTION # 843
A company has a serverless web application that is comprised of AWS Lambda functions. The application experiences spikes in traffic that cause increased latency because of cold starts. The company wants to improve the application's ability to handle traffic spikes and to minimize latency. The solution must optimize costs during periods when traffic is low.

A. Create a recurring schedule in Amazon EventBridge Scheduler. Use the schedule to invoke the Lambda functions periodically to warm the functions.
B. Configure provisioned concurrency for the Lambda functions. Set a fixed concurrency level to handle the maximum expected traffic.
C. Configure provisioned concurrency for the Lambda functions. Use AWS Application Auto Scaling to adjust the provisioned concurrency.
D. Launch Amazon EC2 instances in an Auto Scaling group. Add a scheduled scaling policy to launch additional EC2 instances during peak traffic periods.

Answer: C

Explanation:
Key Requirements:
Handle traffic spikes efficiently and reduce latency caused by cold starts.
Optimize costs during low traffic periods.
Analysis of Options:
Option A:
Provisioned Concurrency:Reduces cold start latency by pre-warming Lambda environments for the required number of concurrent executions.
AWS Application Auto Scaling:Automatically adjusts provisioned concurrency based on demand, ensuring cost optimization by scaling down during low traffic.
Correct Approach:Provides a balance between performance during traffic spikes and cost optimization during idle periods.
Option B:
Using EC2 instances with Auto Scaling introduces unnecessary complexity for a serverless architecture. It requires additional management and does not address the issue of cold starts for Lambda.
Incorrect Approach:Contradicts the serverless design philosophy and increases operational overhead.
Option C:
Setting a fixed concurrency level ensures performance during spikes but does not optimize costs during low traffic. This approach would maintain provisioned instances unnecessarily.
Incorrect Approach:Lacks cost optimization.
Option D:
Using EventBridge Scheduler for periodic invocations may reduce cold starts but does not dynamically scale based on traffic demand. It also leads to unnecessary invocations during idle times.
Incorrect Approach:Suboptimal for high traffic fluctuations and cost control.

NEW QUESTION # 844
An image-hosting company stores its objects in Amazon S3 buckets. The company wants to avoid accidental exposure of the objects in the S3 buckets to the public. All S3 objects in the entire AWS account need to remain private Which solution will meal these requirements?

A. Use AWS Trusted Advisor to find publicly accessible S3 Dockets Configure email notifications In Trusted Advisor when a change is detected manually change the S3 bucket policy if it allows public access
B. Use AWS Resource Access Manager to find publicly accessible S3 buckets Use Amazon Simple Notification Service (Amazon SNS) to invoke an AWS Lambda function when a change it detected. Deploy a Lambda function that programmatically remediates the change.
C. Use Amazon GuardDuty to monitor S3 bucket policies Create an automatic remediation action rule that uses an AWS Lambda function to remediate any change that makes the objects public
D. Use the S3 Block Public Access feature on the account level. Use AWS Organizations to create a service control policy (SCP) that prevents IAM users from changing the setting Apply tie SCP to tie account

Answer: D

Explanation:
The S3 Block Public Access feature allows you to restrict public access to S3 buckets and objects within the account. You can enable this feature at the account level to prevent any S3 bucket from being made public, regardless of the bucket policy settings. AWS Organizations can be used to apply a Service Control Policy (SCP) to the account to prevent IAM users from changing this setting, ensuring that all S3 objects remain private. This is a straightforward and effective solution that requires minimal operational overhead.

NEW QUESTION # 845
A Solutions Architect identified a series of DDoS attacks while monitoring the VPC. The Architect needs to fortify the current cloud infrastructure to protect the data of the clients.
Which of the following is the most suitable solution to mitigate these kinds of attacks?

A. Set up a web application firewall using AWS WAF to filter, monitor, and block HTTP traffic.
B. Using the AWS Firewall Manager, set up a security layer that will prevent SYN floods, UDP reflection attacks, and other DDoS attacks.
C. Use AWS Shield Advanced to detect and mitigate DDoS attacks.
D. A combination of Security Groups and Network Access Control Lists to only allow authorized traffic to access your VPC.

Answer: C

Explanation:
For higher levels of protection against attacks targeting your applications running on Amazon Elastic Compute Cloud (EC2), Elastic Load Balancing(ELB), Amazon CloudFront, and Amazon Route 53 resources, you can subscribe to AWS Shield Advanced. In addition to the network and transport layer protections that come with Standard, AWS Shield Advanced provides additional detection and mitigation against large and sophisticated DDoS attacks, near real-time visibility into attacks, and integration with AWS WAF, a web application firewall.

AWS Shield Advanced also gives you 24x7 access to the AWS DDoS Response Team (DRT) and protection against DDoS related spikes in your Amazon Elastic Compute Cloud (EC2), Elastic Load Balancing(ELB), Amazon CloudFront, and Amazon Route 53 charges.
Hence, the correct answer is: Use AWS Shield Advanced to detect and mitigate DDoS attacks.
The option that says: Using the AWS Firewall Manager, set up a security layer that will prevent SYN floods, UDP reflection attacks and other DDoS attacks is incorrect because AWS Firewall Manager is mainly used to simplify your AWS WAF administration and maintenance tasks across multiple accounts and resources. It does not protect your VPC against DDoS attacks.
The option that says: Set up a web application firewall using AWS WAF to filter, monitor, and block HTTP traffic is incorrect. Even though AWS WAF can help you block common attack patterns to your VPC such as SQL injection or cross-site scripting, this is still not enough to withstand DDoS attacks. It is better to use AWS Shield in this scenario.
The option that says: A combination of Security Groups and Network Access Control Lists to only allow authorized traffic to access your VPC is incorrect. Although using a combination of Security Groups and NACLs are valid to provide security to your VPC, this is not enough to mitigate a DDoS attack. You should use AWS Shield for better security protection. References:
