Your company has an on-premises multi-tier PHP web application, which recently experienced downtime due to a large burst In web traffic due to a company announcement Over the coming days, you are expecting similar announcements to drive similar unpredictable bursts, and are looking to find ways to quickly improve your infrastructures ability to handle unexpected increases in traffic.
The application currently consists of 2 tiers a web tier which consists of a load balancer and several Linux Apache web servers as well as a database tier which hosts a Linux server hosting a MySQL database. Which scenario below will provide full site functionality, while helping to improve the ability of your application in the short timeframe required?

1. A. Failover environment: Create an S3 bucket and configure it for website hostin
2. B. Migrate your DNS to Route53 using zone file import, and leverage Route53 DNS failover to failover to the S3 hosted website.
3. C. Hybrid environment: Create an AMI, which can be used to launch web sewers in EC2. Create an Auto Scaling group, which uses the AMI to scale the web tier based on incoming traffi
4. D. Leverage Elastic Load Balancing to balance traffic between on-premises web servers and those hosted In AWS.
5. E. Offload traffic from on-premises environment: Setup a CIoudFront distribution, and configure CIoudFront to cache objects from a custom origi
6. F. Choose to customize your object cache behavior, and select a TTL that objects should exist in cache.
7. G. Migrate to AWS: Use VM Import/Export to quickly convert an on-premises web server to an AM
8. H. Create an Auto Scaling group, which uses the imported AMI to scale the web tier based on incoming traffi
9. I. Create an RDS read replica and setup replication between the RDS instance and on-premises MySQL server to migrate the database.

Correct Answer: C

You are setting up some EBS volumes for a customer who has requested a setup which includes a RAID (redundant array of inexpensive disks). AWS has some recommendations for RAID setups. Which RAID setup is not recommended for Amazon EBS?

1. A. RAID 1 only
2. B. RAID 5 only
3. C. RAID 5 and RAID 6
4. D. RAID 0 only

Correct Answer: C
With Amazon EBS, you can use any of the standard RAID configurations that you can use with a traditional bare metal server, as long as that particular RAID configuration is supported by the operating
system for your instance. This is because all RAID is accomplished at the software level. For greater I/O performance than you can achieve with a single volume, RAID 0 can stripe multiple volumes together; for on-instance redundancy, RAID 1 can mirror two volumes together.
RAID 5 and RAID 6 are not recommended for Amazon EBS because the parity write operations of these RAID modes consume some of the IOPS available to your volumes.

In Amazon EIastiCache, which of the following statements is correct?

1. A. When you launch an EIastiCache cluster into an Amazon VPC private subnet, every cache node is assigned a public IP address within that subnet.
2. B. You cannot use EIastiCache in a VPC that is configured for dedicated instance tenancy.
3. C. If your AWS account supports only the EC2-VPC platform, E|astiCache will never launch your cluster in a VPC.
4. D. EIastiCache is not fully integrated with Amazon Virtual Private Cloud (VPC).

Correct Answer: B
The VPC must allow non-dedicated EC2 instances. You cannot use EIastiCache in a VPC that is configured for dedicated instance tenancy.

Your customer is willing to consolidate their log streams (access logs application logs security logs etc.) in one single system. Once consolidated, the customer wants to analyze these logs in real time based on heuristics. From time to time, the customer needs to validate heuristics, which requires going back to data samples extracted from the last 12 hours?
What is the best approach to meet your customer’s requirements?

1. A. Send all the log events to Amazon SQS, setup an Auto Scaling group of EC2 sewers to consume the logs and apply the heuristics.
2. B. Send all the log events to Amazon Kinesis, develop a client process to apply heuristics on the logs
3. C. Configure Amazon CIoudTraiI to receive custom logs, use EMR to apply heuristics the logs
4. D. Setup an Auto Scaling group of EC2 syslogd servers, store the logs on S3, use EMR to apply heuristics on the logs

Correct Answer: B
