Question : You have been asked to create VPC for your company. The VPC must support both Internet-facing web applications (ie they need to be publicly
accessible) and internal
private applications (i.e. they are not publicly accessible and can be accessed only over VPN). Both the internet-facing and private applications must be
able to leverage at least
three Availability Zones for high availability. At a minimum, how many subnets must you create within your VPC to achieve this?

1. 2
2. 3
3. Access Mostly Uused Products by 50000+ Subscribers
4. 6

Explanation:

Question : You have a VPC that is built in a single region and it currently makes use of availability zones. In this VPC you have deployed a very
important two-tier web application.
Your web application uses using Elastic Load Balancing and Auto Scaling. The application depends on synchronous replication (which requires a very low
latency connectivity) to the
database. The application needs to remain fully available even if one application Availability Zone goes down, and Auto Scaling cannot launch new instances
in the remaining
Availability Zones. How can the current architecture be enhanced to ensure this?

1. Deploy your web application into three AZ's. Set your Auto Scaling policy minimum to handle 50 percent peak load per zone.
2. Deploy your web application in two regions using a round robin DNS and set your Auto Scaling minimums set for 100 percent peak load per region.

4. Deploy your web application in to two regions using Weighted Round Robin DNS. Set your Auto Scaling policy minimums set for 50 percent peak
load per Region.

Explanation: In this scenario if you lost an availability zone, you would still have 2 other Availability Zones available each that is configured to handle 50%
peak load per zone. 50% + 50% = 100%.

Option 3 : In this scenario if you lost an availability zone, you would still have 2 other Availability Zones available each that is configured to handle
only 33% peak load per zone. 33% + 33% = 66% peak load, so your application would fall over if your load exceeded 66%.
