The databases maintain consistency by replicating changes to each other as and when they occur. The site uses using Elastic Load Balancing and Auto Scaling. The site itself is in a two-tier configuration with web servers in the front end and database servers at the back end. You work for a cosmetic company which has their production website on AWS. Your EC2 instances will be able to communicate over this port as soon as the relevant Time To Live (TTL) expires. Open the port on the existing security group. Your EC2 instances will be able to communicate over this port immediately.ĭ. Your EC2 instances will be able to communicate over this port immediately.Ĭ. Open the port on the existing network Access Control List. Your EC2 instances will be able to communicate on this port after a reboot.ī. What steps should you take to do this, and how quickly will the change occur?Ī. This application has been rolled out to production and you need to open this port globally to the internet. Your company has created a new custom application which connects to mobile devices using a custom port. All EC2 instances are in the same security group. Inside the public subnet is a fleet of EC2 instances which are the result of an autoscaling group. The VPC contains 3 subnets, 1 of which is public and the other 2 are private. Your company runs their production environment on AWS and has a custom VPC. You are a solutions architect working for a large oil and gas company. Create a read replica of the existing EC2 instance and then take your snapshots from the read replica and not the live EC2 instance. Take a snap of only the two new volumes.ĭ. Add two additional volumes to the existing RAID 0 volume and mirror these volumes creating a RAID 10. Once the snapshots are complete, start the EC2 instance and ensure that all relevant volumes are remounted.Ĭ. Stop the EC2 instance and take a snapshot of each EC2 instance independently.

Take a snapshot of each volume independently, while the EC2 instance is running.ī. You decide to take a snapshot of all three volumes every 24 hours. Your application is only used during office hours, so you can afford to have some down time in the middle of the night if required. Your company recently had an outage and lost some key data and have since decided that they will need to run nightly back ups.

The results are then stored on a custom MySQL database which is hosted on an EC2 instance which has 3 volumes, the root/boot volume, and then 2 additional volumes which are striped in to a RAID 1. You are a solutions architect working for a company that specializes in ingesting large data feeds (using Kinesis) and then analyzing these feeds using Elastic Map Reduce (EMR).

In order to build the key namespace correctly, you must understand the total amount of storage needs for each S3 bucket. You must know the size of the individual objects being written to S3, in order to properly design the key namespace.ĭ. You must find out the total number of requests per second at peak usage.Ĭ. You must know how many customers the company has today, because this is critical in understanding what their customer base will be in two years.ī. What other information must you gather from this customer in order to determine whether S3 is the right option?Ī. Due to the nature of their business, they are expecting sudden and large increases in traffic to and from S3, and need to ensure that it can handle the performance needs of their application. The company is lean on funding, and wants to minimize operational costs, however, they have an aggressive marketing plan, and expect to double their current installation base every six months. A startup company hired you to help them build a mobile application, that will ultimately store billions of images and videos in S3.
