Question :

Which consistency model does the AWS US West (Oregon) Region support for the PUTS operation of objects?


1. Eventual
2. Concurrent
3. Access Mostly Uused Products by 50000+ Subscribers
4. Full


Correct Answer : Get Lastest Questions and Answer :

Explanation: AWS supports various regions to upload objects. The AWS Oregon (US West) region offers read after write consistency for PUTS and eventual consistency
for the overwrite PUTS and DELETE operation. With read after write consistency, if the user creates an object unlike eventual consistency it will be visible
immediately without any delays. It is useful for making a distributed system with less latency. With an eventual consistency model the user will have high
durability. However, with read-after-write the user will have less latency and immediate availability.

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

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.

load per Region.
