Get ready to excel in your AWS Solutions Architect certification with this comprehensive collection of questions and answers. Covering critical topics like cloud architecture design, AWS services, security best practices, and cost optimization, these Q&A sessions will help you gain a deep understanding of AWS concepts and prepare effectively for the exam. Whether you are a beginner or an experienced professional, these answers provide clear explanations and practical examples to solidify your AWS knowledge and boost your confidence.

Test your Skills

1.You are running a news website in the eu-west-1 region that updates every 15 minutes. The website has a world-wide audience it uses an Auto Scaling group behind an Elastic Load Balancer and an Amazon RDS database Static content resides on Amazon S3, and is distributed through Amazon CloudFront. Your Auto Scaling group is set to trigger a scale up event at 60% CPU utilization, you use an Amazon RDS extra large DB instance with 10.000 Provisioned IOPS its CPU utilization is around 80%. While freeable memory is in the 2 GB range.


Web analytics reports show that the average load time of your web pages is around 1 5 to 2 seconds, but your SEO consultant wants to bring down the average load time to under 0.5 seconds.

How would you improve page load times for your users? (Choose 3 answers)

 
A. Lower the scale up trigger of your Auto Scaling group to 30% so it scales more aggressively.
 
B. Add an Amazon ElastiCache caching layer to your application for storing sessions and frequent DB queries
 
C. Configure Amazon CloudFront dynamic content support to enable caching of re-usable content from your site
 
D. Switch Amazon RDS database to the high memory extra large Instance type
 
E. Set up a second installation in another region, and use the Amazon Route 53 latency-based routing feature to select the right region.
 
 

2. You require the ability to analyze a customer’s clickstream data on a website so they can do behavioral analysis. Your customer needs to know what sequence of pages and ads their customer clicked on. This data will be used in real time to modify the page layouts as customers click through the site to increase stickiness and advertising click-through. Which option meets the requirements for captioning and analyzing this data?

A. Log clicks in weblogs by URL store to Amazon S3, and then analyze with Elastic MapReduce
 
B. Push web clicks by session to Amazon Kinesis and analyze behavior using Kinesis workers
 
C. Write click events directly to Amazon Redshift and then analyze with SQL
 
D. Publish web clicks by session to an Amazon SQS queue men periodically drain these events to Amazon RDS and analyze with sol
 
 

3. Refer to the architecture diagram above of a batch processing solution using Simple Queue Service (SOS) to set up a message queue between EC2 instances which are used as batch processors Cloud Watch monitors the number of Job requests (queued messages) and an Auto Scaling group adds or deletes batch servers automatically based on parameters set in Cloud Watch alarms. You can use this architecture to implement which of
the following features in a cost effective and efficient manner?

A. Reduce the overall lime for executing jobs through parallel processing by allowing a busy EC2 instance that receives a message to pass it to the next instance in a daisy-chain setup.
 
B. Implement fault tolerance against EC2 instance failure since messages would remain in SQS and worn can continue with recovery of EC2 instances implement fault tolerance against SQS failure by backing up messages to S3.
 
C. Implement message passing between EC2 instances within a batch by exchanging messages through SOS.
 
D.Coordinate number of EC2 instances with number of job requests automatically thus Improving cost effectiveness.
 
E. Handle high priority jobs before lower priority jobs by assigning a priority metadata field to SQS messages.
 
 

4. You are designing an intrusion detection prevention (IDS/IPS) solution for a customer web application in a single VPC. You are considering the options for implementing IOS IPS protection for traffic coming from the Internet.

Which of the following options would you consider? (Choose 2 answers)

A. Implement IDS/IPS agents on each Instance running In VPC
 
B. Configure an instance in each subnet to switch its network interface card to promiscuous mode and analyze network traffic.
 
C. Implement Elastic Load Balancing with SSL listeners In front of the web applications
 
D. Implement a reverse proxy layer in front of web servers and configure IDS/IPS agents on each reverse proxy server.
 

5. You are designing a multi-platform web application for AWS The application will run on EC2 instances and will be accessed from PCs. tablets and smart phones Supported accessing platforms are Windows. MACOS. IOS and Android Separate sticky session andSSL certificate setups are required for different platform types which of the following describes the most cost effective and performance efficient architecture setup?

A. Setup a hybrid architecture to handle session state and SSL certificates on-prem and separate EC2 Instance groups running web applications for different platform types running in a VPC.
 
B. Set up one ELB for all platforms to distribute load among multiple instance under it Each EC2 instance implements ail functionality for a particular platform.
 
C. Set up two ELBs The first ELB handles SSL certificates for all platforms and the second ELB handles session stickiness for all platforms for each ELB run separate EC2 instance groups to handle the web application for each platform.
 
D. Assign multiple ELBS to an EC2 instance or group of EC2 instances running the common components of the web application, one ELB for each platform type Session stickiness and SSL termination are done at the ELBs.
