Q

You use the Amazon CloudWatch as primary monitoring system for web app. After a recent software deploy, your users are getting intermittent 500 internal server error when using web app.

You want to create the CloudWatch alarm and notify on-call engineer for when this occurs. How can you accomplish this using AWS services?

A

Create CloudWatch logs to define metrics of 500 internal error, and create alarm using SNS to notify on-call engineers of error

Q

You are designing a multi-platform web app for AWS. The app will run on EC2 instances and will be accessed from PC’s, tablets, and smart phones. Supported platforms are Windows, MacOS, iOS, and Android. The Sticky Sessions and SSL cert are separate setups required for different platform types.

Which describes the most cost effective and performance efficient architecture setup? Two things.. A. S.

A

Assign EC2 instances running components of web app to multiple ELB’s. One ELB change for each platform type.

Set session to sticky.

ELB = Elastic Load Balancing

Q

You’re migrating a legacy client-server app for AWS. The app responds to specific DNS visible domain (e.g. www.example.com) and server 2-tier architecture, with multiple applications for the servers and database. Remote clients use TCP to connect to the app of servers.The application servers need to know the IP address of clients to function properly and are currently getting that info from TCP socket. A Multi-AZ MySQL instance will be used for database. During the migration, you change app code but you have to file a change request.

How would you implement the architecture on AWS in order to maximize on scaling and availability?

2 Steps mainly… FCR IPP - E TL & PP 2AZ

A
  1. File a change request to implement Proxy Protocol support in the app.
  2. Use ELB with TCP Listener and a Proxy Protocol enabled to distribute the load on 2 app servers in different AZ’s

Bonus: What is the difference between 2 tier and 3-tier architecture?
A two-tier DB architecture either buries the application logic within the server database, on the client (inside the UI), or both of them. A three-tier DB architecture buries the process or application logic in the middle-tier. Thus, it acts as a separate entity from the Client/ User Interface and the data Interface.

Q

Your app currently leverages AWS auto-scaling to grow and shrink as a load increases/decreases, and has been performing well. Your market team expects a steady ramp up in traffic to follow an upcoming campaign resulting in 20x growth in traffic over 4 weeks. Your forecast for approximate number of EC2 instances needed to meet peak demand is 175.

What should you do to avoid potential service disruptions during the ramp up in traffic?

A

Check service limits in the Trusted Advisor and adjust as necessary

Then the forecast count remains within the limits.

Q

You have web app running on 6 EC2 instances, consuming 45% of resources on each instance. You are using the auto-scaling to make sure that 6 instances are running at all times. The number of request this app processes is consistent and does not experience spikes. The app is critical to the business and you want high availability at all times. You want the load to be distributed evenly between all instances. You also want to use the same AMI for all instances.

What architecture choice should you make? Couple things to mention here…

A

Deploy 3 EC2 instances to one AZ and 3 more in another AZ.

Use ELB - aka Amazon Elastic Load Balancer.

Q

You are designing an app that has protected health info. Security and compliance requirements on the app mandate all protected health info use encryption at rest and in the transit mode. The app uses a 3-tier architecture, where data should flow through the load balancers and is stored on EBS volumes for processing. The results are stored in S3 using an AWS SDK.

What satisfies the security requirements?
Hint=T.S.O.

A
  • TCP load balancers
  • SSL termination on AWS to create EC2 instances
  • OS-level disk encryption on EBS volumes
    *-
  • The S3 with server-side encrytion and SSL termination on load balancers
  • SSL listener on the Amazon to create EC2 instances
  • EBS encryption on the EBS volumes containing PHI and S3 with a server-side encryption.

Q

A Startup deploys it’s photo-sharing site in a VPC. An elastic load balancer distributes web traffic across 2 subnets. Then the load balancer set to stickiness is configured to use AWS-generated session cookie with TTL of 5 min. The web server to change auto-scaling group is configured as min-size=4, max-size=4. The Startup is preparing for a public launch by running the load-testing software installed on single EC2 instance - that’s running in us-west-2a. After 60 min of load-testing, the web server logs shows attached screenshot:

Which recommendations can be helpful to ensure load-testing HTTP requests are evenly distributed across 4 web servers?

A

Result is to reconfigure the load-testing software to re-resolve the DNS for each web request

Q

To serve webtraffic for a popular product, the CFO and IT Director have purchased 10 m1.large heavy utilization Reserved Instances evenly spread across 2 AZ’s. Route53 is used to deliver traffic on ELB. After several months, product grows even more popular and need to add capacity. As a result, comapny purchases 2 c3.2xlarge medium utization instances. You register the 2 new c3 instances with ELB and quickly find that the ML of large instances at 100% capacity and the c3.2xlarge instances have significant capacity unused.

Which option is most cost effective and uses EC2 capacity most effectively?

A

Use a separate ELB for each instance type

Distribute load to ELB’s with Route53 weighted round-robin

Q

AWS customer is deploying a web app that is composed of front-end running EC2 confidential data and stored on S3. The customer Security policy is that all accessing operations to this sensitive data must authenticate and authorize by centralized access management system, and operated by separate Security team. In addition, the web application team owns and admins the EC2 web-front instance and prohibited from ahving any ability to access data that circumvents this centralized access management system.

What are configuration that will support these requirements?

A

Have web app provisioned as trusted to users STS tokens, entitling download of approved data directly from S3.

Q

Enterprise customer is starting their migration to the cloud. Their main reason is agility and want to make their internal Microsoft AD available to the many apps running on AWS. This is so internal users only have to remember one set of creds and as a central point users take control for the leavers and joiners.

How could they make their AD secure and highly available with minimal on-premise infrastructure changes, most cost and time efficient way?

A

By using a VPC, they could create extention to their data canter and make use of resilient hardware IPSEC tunnels. They could then have 2 domains considered to controller instances that are joined to existing domain and reside within the different subnets in different AZ’s.
