1) A two-tier web application is launched by your CloudFormation template. There is a failure of process when you try creating a development stack in us-west-1. What is the possible issue? 

A) IAM roles referenced in the template are invalid in us-west-1

B) AMIs referenced in the template are unavailable in us-west-1

C) There cannot be the same Name tag for 2 ELB Classic Load Balancers

D) Launching of CloudFormation templates can only be done in one region. 

Answer: B – AMIs are stored in a region and it is not possible to access them in other regions. It is necessary to copy the AMI for using it in another region. IAM roles remain valid across the account.  

2) Your application needs to write to an SQS queue. The corporate security policies require encryption of AWS credential, with a minimum rotation of once every week. How to provide secure credentials for allowing the application to write to the queue?

A) By Encrypting the access key in the source code of the application

B) By enabling fetching of the access key by the application at run time from an Amazon S3 bucket

C) By Launching the Amazon EC2 instance of the application with an IAM role

D) By enrolling the instance in Active Directory domain and using AD authentication. 

Answer: C – IAM roles are automatically rotated since they are based on temporary security tokens. It is not possible to rotate the keys in the source code. If you don’t have the credentials for an S3 bucket, retrieving credentials from it is impossible. Access to AWS resources won’t be granted by Active Directory authorization.  

3) Temporarily inconsistent results could be returned by which of the following operations?

A) To get an object from Amazon S3 after its initial creation

B) Selection of a row from an Amazon RDS database after its insertion

C) Selection of a row from an Amazon RDS database after its deletion

D) To get an object from Amazon S3 after its deletion

Answer: D – There is an eventual consistency in S3 for overwriting DELETES and PUTS 

4) A web application reads an item from a DynamoDB table, alters an attribute and writes it back to the table. It needs to be ensured that simultaneous change from one process is not overwritten by another process. How is concurrency ensured?

A) Use of a conditional write for implementing optimistic concurrency

B) Use of a conditional write for implementing pessimistic concurrency

C) Locking of the item upon reading for implementing optimistic concurrency

D) Locking of the item upon reading for implementing pessimistic concurrency

Answer: A – Optimistic concurrency ensure the value has not changed by checking it upon save. Pessimistic concurrency locks the row or item in the data for preventing it from changing. Item locking is not supported by DynamoDB and optimistic concurrency can be perfectly implemented through conditional writes.  

5) One Amazon VPC has a three-tier web application (web, app and data). The app and web tiers are in separate subnets and span 2 Availability Zones, sitting behind ELB Classic Load Balancers. In the database subnets is the data tier that is a Multi-AZ Amazon RDS MySQL database instance. There is a timeout error received on calling the database tier from the app tier instances. What could be the cause of this?

A) The MySQL database rights are not provided to the IAM role that is associated with the app tier instances

B) Traffic on port 3306 from app instances is not allowed by the security group for Amazon RDS instance

C) There is no public IP address for the Amazon RDS database instance

D) The Amazon VPC does not have a defined route between the database tier and the app tier. 

Answer B – All network traffic is blocked by default by the security groups. So, a timeout error can result if proper configuration of a group is not done. My SQL Security is not controlled by IAM. In an Amazon VPC, each subnet has routes to every other subnet. Public IP addresses are not required for internal traffic within Amazon VPC.

Designed by experts, practice tests help by simulating the real exam scenario. The questions are made according to the official documentation for exam syllabus. When you take multiple practice tests, you will find unique questions in each of them. No repetition means you have more questions to improve your knowledge on. 

The AWS Developer Certification practice tests are mainly provided so that candidates can improve their exam preparation and self-evaluate their present situation, thus helping them gain more confidence. These tests are extremely useful for mental preparation for taking the exam. If your practice AWS mock tests several times before your certification exam, you will be better prepared for the actual exam. 

Hence, practice tests are essentially a studying and personal assessment tool. It is recommended to take these tests in the last week of your study to assess how well you have prepared. Make sure you have enough time after taking the practice tests to work on your weak areas or even reschedule the examination without penalty. 

The process of buying a token for the official AWS practice exam is the same as scheduling the real exams. Firstly, you have to visit AWS Training and then click on the “Schedule an Exam” option. Thereafter, you will have to keep on clicking the relevant links until you reach the Testing Supplier system, where you can purchase a token. 

The purchased token will remain active on your account until you choose to start the practice exam. The countdown for the time limit doesn’t start when the token is bought. It starts counting down only when you begin your practice exam. 

It is worth noting that the official AWS practice exams cannot be retaken free of cost. In fact, each time you, or anyone else for that matter, take the practice exam you have already taken, the question will always remain the same. 

The exam readiness training prepares you for the exam by covering the topic areas of the exam and mapping them to AWS development. It also identifies the specific areas you need to study. You can go through the sample exam questions based on different topic areas. You will learn concepts in a way that helps you eliminate the wrong responses. 

The exam readiness course is delivered through a mix of sample exam questions and digital training, with an overall duration of 1.5 hours. The main concepts covered include: 

• Exam structure and overview 
• Content domains and breakdown of questions 
• Concepts and topics within content domains 
• Question structure and techniques for interpretation 
• Sample exam questions 

The training contains six e-learning modules, each with the following duration: 

AWS is a vast platform requiring extensive knowledge of cloud management and application deployment. There are more than 100 services of AWS, with new ones being added on a regular basis. Each service is unique on its own with its GUI and CLI command set. To master any AWS service, you need to understand the basics first. 

As far as difficulty of the exam is concerned, it is always going to be subjective. What can be said for sure that the difficulty of an exam is higher if it is higher on the AWS certification hierarchy. The Cloud Practitioner can be the easiest, the professional level exams being the most challenging and Associate level exams can be said to be somewhere in between in terms of difficulty level. 

When preparing for Associate exams like this, you should look to use every resource possible. You need to spend a considerable amount of time with your preparation and have a proper study plan. 

The Developer exam questions can be quite specific, and the answers aren’t necessarily straightforward. The testing objective is extremely broad, so you should never rely on one study material. Don’t expect the exam to be a breeze; you will have to put in hours of preparation.   

You can take the AWS exams via the PSI or Pearson VUE network of testing centers. You are required to provide two forms of personal identification at the examination for identification. A primary identification form has to be a current and valid driver’s license and passport issued by the government. A second primary Id can also serve as a secondary identification form, which can also include ATM or debit cards. 

AWS exams have strict security procedures with personal items, food and drink prohibited in the testing area. Any wearable device may also be inspected. The security procedures and admission requirements are outlined in full in the first step when you schedule the exam.

The following AWS certifications are suited for developers: 

• AWS Certified Developer – Associate: This certification is made for software developers with a minimum 1-year experience in designing and maintaining applications on AWS platform. Candidates are required to have a good knowledge of at least one high level programming language. 
• AWS Certified DevOps Engineer: This certification covers static systems as well as systems that change over time. It also has in-depth coverage of design, maintenance and provisioning of distributed systems and applications on AWS platforms and general application life cycle. This certification is great for progressing from associate-level certifications to Solutions Architect Professional level certification. 

The information on AWS services has been updated in Developing on AWS course and it now includes more hands-on lab time, allowing learners to make a complete solution that covers most services in the course. 

The Exam Readiness- AWS certified Developer - Associate course is now aligned with the latest exam version released in June 2019. 

If you are starting with no prior knowledge of AWS, you need to get a bit of experience with the fundamentals of the services. This is done because the Developer exam is not for testing out your knowledge of all the products and services offered by AWS, it’s for demonstrating that you have the skill of using them together. So, a good place for you, a Java Developer, to start in AWS will be the AWS Technical Essentials course. You need a high-level of the services provided by the AWS. Next step is to just dive into the use cases to see how you can stand out while developing apps on the AWS platform. For this, you need to know how to loosely couple applications. All the above-mentioned topics are covered in the Developers learning path of AWS. 

A front-end developer usually doesn’t directly interface with AWS the way DevOps team members do. Yet, frontend developers aren’t necessarily completely oblivious to AWS. AWS is very much a part of their daily operations. 

Lack of familiarity with the AWS platform can potentially limit the effectiveness of a developer. Learning about AWS helps the frontend developers communicate with the backend developers on their team. 

Taking the AWS certification exam provides an idea about how AWS works and how different parts of the system fit together. Working knowledge of AWS can turn any frontend developer into a more effective developer. 

• Get more done with the tools you are familiar with: As a .NET developer, you will be provided with all the tools and integrations you would expect from AWS. Hence, there is a short learning curve for .NET developers to make use of the most innovative cloud 
• Managed support for full Windows stack: There is support for anything you might require for building and running Windows applications like Active Directory, Windows File Server and Microsoft SQL Server. 
• Use the latest cloud technologies for maximum innovation: AWS provides native support for .NET over numerous modern tools and services, like the AWS cloud Development Kit and AWS Lambda.
