The book contains several testimonials like the one below:
Successfully cleared the AWS Solutions Architect Associate SAA-C03 with a score of 824, surpassing my expectations. The exam presented a mix of question difficulties, with prominent topics being Kinesis, Lakeformation, Big Data tools, and S3. Given the declining cybersecurity job market in Europe post-2021, I’m contemplating a transition to cloud engineering.
For preparation, I leveraged Stephane Mareek’s course, Tutorial dojo’s practice tests, and flashcards. My manager also shared his AWS skill builder account. Post evaluation, I found Mareek’s practice tests to be outdated and more challenging than required, with his course delving too deeply into some areas. In contrast, Tutorial dojo’s materials were simpler. My scores ranged from 65% on Mareek’s tests to 75-80% on Tutorial dojo, with a 740 on the official AWS practice test. Sharing this for those on a similar journey.
Sample Question and Detailed Answer You’ll Find in this eBook:
A microservice application is being hosted in the ap-southeast-1 and ap-northeast-1 regions. The ap-southeast-1 region accounts for 80% of traffic, with the rest from ap-northeast-1. As part of the company’s business continuity plan, all traffic must be rerouted to the other region if one of the regions’ servers fails.
Which solution can comply with the requirement?
- A. Set up an 80/20 weighted routing in the application load balancer and enable health checks.
- B. Set up an 80/20 weighted routing in the network load balancer and enable health checks.
- C. Set up an 80/20 weighted routing policy in AWS Route 53 and enable health checks.
- D. Set up a failover routing policy in AWS Route 53 and enable health checks.
Correct Answer: C. Establish an 80/20 weighted routing policy in AWS Route 53 and incorporate health checks.
The correct solution for this scenario is to use AWS Route 53’s weighted routing policy with health checks. This setup allows the distribution of traffic across multiple AWS regions based on assigned weights (in this case, 80% to ap-southeast-1 and 20% to ap-northeast-1) and automatically reroutes traffic if one region becomes unavailable due to server failure.
Option C is correct because AWS Route 53’s weighted routing policy allows you to assign weights to resource record sets (RRS) which correspond to different AWS regions. When combined with health checks, Route 53 can monitor the health of the application in each region. If a region becomes unhealthy, Route 53 will reroute traffic to the healthy region based on the configured weights.
Option A and B are incorrect because application and network load balancers operate at the regional level, not the global level. Therefore, they cannot reroute traffic between regions.
Option D, while involving Route 53, suggests a failover routing policy, which is not suitable for distributing traffic with a specific percentage split across regions. Failover routing is typically used for active-passive failover, not for load distribution, which doesn’t align with the requirement to handle traffic in an 80/20 proportion.
The weighted routing policy of AWS Route 53, with appropriate health checks, satisfies the business requirement by distributing traffic in the specified ratio and ensuring business continuity by redirecting traffic in the event of a regional failure.
