The interviewer will want to know if you have the technical skills and knowledge to handle this type of work. Data quality is an important part of data engineering, so it’s important to show that you understand how to handle these issues. To answer this question, explain the steps you take when dealing with missing values or outliers in your data. These steps might include identifying and investigating the source of the issue, determining what action needs to be taken (e.g., deleting, imputing, or transforming the data), and implementing a solution. This question is designed to test your technical knowledge and experience in setting up data visualizations and analytics dashboards with popular data visualization tools such as QuickSight or Tableau.
- Vm.swappiness is a tunable bit parameter that controls how much the part supports swap over RAM.
- This ensures seamless integration and communication between on-premises and cloud environments, enabling workloads to be distributed effectively across both platforms.
- In terms of compliance, I ensure adherence to regulatory standards by using AWS Artifact for on-demand access to AWS’ compliance reports and aligning our practices with well-architected framework recommendations.
- So, there will not be any increased workload on the RDS MySQL instance, hence resolving the contention issue.
- Security groups – serve as a firewall for EC2 instances, allowing you to regulate inbound and outgoing traffic at the instance level.
I’m also adept at setting up different routing policies like Simple, Failover, Geolocation, Latency, Multivalue answer, and Weighted. Monitoring is crucial; CloudWatch and CloudTrail help track health and performance while detecting anomalies. For database migrations, I’ve leveraged AWS Schema Conversion Tool (SCT) to convert the source database schema to a format compatible with the target AWS service. To ensure high availability, we used Multi-AZ deployments of RDS, EC2 Auto Scaling, and Elastic Load Balancer. Post-implementation, it’s crucial to continuously monitor the system to ensure the changes have improved performance and adjust if necessary.
In CloudFront what happens when content is NOT present at an Edge location and a request is made to it?
This question is all about assessing your adaptability and problem-solving skills. As a DevOps engineer, you’re likely to face situations where technologies change or become obsolete, and how you adapt to these changes can significantly impact the efficiency and effectiveness of operations. The interviewer wants to see if you can keep calm under pressure, create a plan, and execute it to ensure a smooth transition.
Now since all the cores are on the processor the temperature should be kept at an optimal state so that all the cores can perform at the highest performance. Once the AMI is created, aws cloud engineer The administrator will need the 12-digit account number of the #2 AWS account. We can use the Internet routable IP address, which is a public IP address of your NAT device.

For example, creating and using subnets can help reduce congestion by making sure that the traffic destined for a subnet stays in that subnet. This helps in efficiently routing the to the network, which reduces the network’s load. After pushing the Docker image to ECR, we proceed with creating an ECS task definition that references the image stored in ECR. The task definition specifies the required resources, https://remotemode.net/ such as CPU and memory, along with any environment variables or configurations needed for the container to run properly. Create public and private subnets by specifying their respective CIDR blocks, ensuring they fall within the VPC’s CIDR block range. Remember, these questions provide a starting point but be prepared for variations and follow-up questions that dive deeper into your expertise.
- The T2 Instances are intended to give the ability to burst to a higher performance whenever the workload demands it and also provide a moderate baseline performance to the CPU.
- You can use a CI to ascertain what your AWS resource looks like at any given point in time.
- We can achieve this by defining tags on the test and production instances and then adding a condition to the IAM policy that allows access to specific tags.
- By systematically addressing these factors and continuously monitoring performance, you can identify and resolve performance issues with EC2 instances, ensuring optimal performance for your applications in AWS.
- Our interview questions and answers do not represent any organization, school, or company on our site.
- This ensures high availability and minimizes the impact of failures or outages in one zone on your overall application performance.
- Using services like S3 lifecycle policies or Glacier for long-term storage can help manage costs.
