Q1. You havejust discovered that you can upload your objects to Amazon S3 using MuItipart Upload API. You start to test it out but are unsure of the benefits that it would provide. Which of the following is not a benefit of using multipart uploads?

A. You can begin an upload before you know the final object size.

B. Quick recovery from any network issues.

C. Pause and resume object uploads.

D. It's more secure than normal upload.

Answer: D

Explanation:

MuItipart upload in Amazon S3 allows you to upload a single object as a set of parts. Each part is a contiguous portion ofthe object's data. You can upload these object parts independently and in any order.

If transmission of any part fails, you can re-transmit that part without affecting other parts. After all parts of your object are uploaded, Amazon S3 assembles these parts and creates the object. In general, when

your object size reaches 100 MB, you should consider using multipart uploads instead of uploading the object in a single operation.

Using multipart upload provides the following advantages:

Improved throughput—You can upload parts in parallel to improve throughput.

Quick recovery from any network issues—SmaIIer part size minimizes the impact of restarting a failed upload due to a network error.

Pause and resume object upIoads—You can upload object parts over time. Once you initiate a multipart upload there is no expiry; you must explicitly complete or abort the multipart upload.

Begin an upload before you know the final object size—You can upload an object as you are creating it. Reference: http://docs.aws.amazon.com/AmazonS3/latest/dev/uploadobjusingmpu.htmI

Q2. An edge location refers to which Amazon Web Service?

A. An edge location is refered to the network configured within a Zone or Region

B. An edge location is an AWS Region

C. An edge location is the location of the data center used for Amazon CIoudFront.

D. An edge location is a Zone within an AWS Region

Answer: C

Explanation:

Amazon CIoudFront is a content distribution network. A content delivery network or content distribution network (CDN) is a large distributed system of sewers deployed in multiple data centers across the world. The location of the data center used for CDN is called edge location.

Amazon CIoudFront can cache static content at each edge location. This means that your popular static content (e.g., your site’s logo, navigational images, cascading style sheets, JavaScript code, etc.) will be available at a nearby edge location for the browsers to download with low latency and improved performance for viewers. Caching popular static content with Amazon CIoudFront also helps you offload requests for such files from your origin sever — CIoudFront serves the cached copy when available and only makes a request to your origin server if the edge location receMng the browser’s request does not have a copy of the file.

Q3. Your company has been storing a lot of data in Amazon Glacier and has asked for an inventory of what is in there exactly. So you have decided that you need to download a vault inventory. Which of the following statements is incorrect in relation to Vault Operations in Amazon Glacier?

A. You can use Amazon Simple Notification Service (Amazon SNS) notifications to notify you when the job completes.

B. A vault inventory refers to the list of archives in a vault.

C. You can use Amazon Simple Queue Service (Amazon SQS) notifications to notify you when the job completes.

D. Downloading a vault inventory is an asynchronous operation.

Answer: C

Explanation:

Amazon Glacier supports various vault operations.

A vault inventory refers to the list of archives in a vault. For each archive in the list, the inventory provides archive information such as archive ID, creation date, and size. Amazon Glacier updates the vault inventory approximately once a day, starting on the day the first archive is uploaded to the vault. A vault inventory must exist for you to be able to download it.

Downloading a vault inventory is an asynchronous operation. You must first initiate a job to download the inventory. After receMng the job request, Amazon Glacier prepares your inventory for download. After the job completes, you can download the inventory data.

Given the asynchronous nature of the job, you can use Amazon Simple Notification Service (Amazon SNS) notifications to notify you when the job completes. You can specify an Amazon SNS topic for each indMdual job request or configure your vault to send a notification when specific vault events occur. Amazon Glacier prepares an inventory for each vault periodically, every 24 hours. If there have been no archive additions or deletions to the vault since the last inventory, the inventory date is not updated. When you initiate a job for a vault inventory, Amazon Glacier returns the last inventory it generated, which is a point-in-time snapshot and not real-time data. You might not find it useful to retrieve vault inventory for each archive upload. However, suppose you maintain a database on the client-side associating metadata about the archives you upload to Amazon Glacier. Then, you might find the vault inventory useful to reconcile information in your database with the actual vault inventory.

Q4. Your startup wants to implement an order fulfillment process for selling a personalized gadget that needs an average of 3-4 days to produce with some orders taking up to 6 months you expect 10 orders per day on your first day. 1000 orders per day after 6 months and 10,000 orders after 12 months.

Orders coming in are checked for consistency men dispatched to your manufacturing plant for production quality control packaging shipment and payment processing If the product does not meet the quality standards at any stage of the process employees may force the process to repeat a step Customers are notified via email about order status and any critical issues with their orders such as payment failure.

Your case architecture includes AWS Elastic Beanstalk for your website with an RDS MySQL instance for customer data and orders.

How can you implement the order fulfillment process while making sure that the emails are delivered reliably?

A. Add a business process management application to your Elastic Beanstalk app servers and re-use the ROS database for tracking order status use one of the Elastic Beanstalk instances to send emails to customers.

B. Use SWF with an Auto Scaling group of actMty workers and a decider instance in another Auto Scaling group with min/max=I Use the decider instance to send emails to customers.

C. Use SWF with an Auto Scaling group of actMty workers and a decider instance in another Auto Scaling group with min/max=I use SES to send emails to customers.

D. Use an SOS queue to manage all process tasks Use an Auto Scaling group of EC2 Instances that poll the tasks and execute them. Use SES to send emails to customers.

Answer: C

Q5. A user is currently building a website which will require a large number of instances in six months, when a demonstration of the new site will be given upon launch.

Which of the below mentioned options allows the user to procure the resources beforehand so that they need not worry about infrastructure availability during the demonstration?

A. Procure all the instances as reserved instances beforehand.

B. Launch all the instances as part of the cluster group to ensure resource availability.

C. Pre-warm all the instances one month prior to ensure resource availability.

D. Ask AWS now to procure the dedicated instances in 6 months.

Answer: A

Explanation:

Amazon Web Services has massive hardware resources at its data centers, but they are finite. The best way for users to maximize their access to these resources is by reserving a portion of the computing capacity that they require. This can be done through reserved instances. With reserved instances, the user literally reserves the computing capacity in the Amazon Web Services cloud.

Q8. You've been brought in as solutions architect to assist an enterprise customer with their migration of an e-commerce platform to Amazon Virtual Private Cloud (VPC) The previous architect has already deployed a 3-tier VPC, The configuration is as follows:

VPC: vpc-2f8bc447 IGW: igw-2d8bc445 NACL: ad-208bc448

5ubnets and Route Tables: Web sewers: subnet-258bc44d

Application servers: subnet-248bc44c Database sewers: subnet-9189c6f9 Route Tables:

rrb-218bc449 rtb-238bc44b Associations:

subnet-258bc44d : rtb-218bc449 subnet-248bc44c : rtb-238bc44b subnet-9189c6f9 : rtb-238bc44b
