- Maven is used for building Java applications.
- Declarative Pipeline Syntax is not the only way to write a Jenkins file.
- Scripted Pipeline is a more recent feature in Jenkins.
- You can trigger a Jenkins job only if the previous job is successful via the Trigger only if the build is stable option.
- Changing the pipeline script from SCM will allow you to tell Jenkins the URL of a specific GitLab code repository.
- Con expressions can be used to automate Jenkins jobs that are manually triggered.
- example: using a time condition to trigger a job at 6:00 AM every day.
AWS
- Rebooting an EBS-backed EC2 instance does not mean it will be running on a new host computer.
- To better view data on a CloudWatch graph, you can select the Y axis that plots CPU utilization data.
- Stopping and then restarting an EBS-backed instance does not disassociate the Elastic IP from the instance.
- Cost Allocation Tags and AWS billing reports can be used to find the cost distribution for different types of EC2 instances deployed in a region.
- The default maintenance window will be utilized if a user has not specified the maintenance window for an RDS instance.
- Auto Scaling does not perform the action of rebooting instances.
- Deleting a VPC with a running NAT instance will not be allowed.
- If a CloudFormation stack fails during the process of creating resources, it will rollback all created services.
- ELB will intercept the request to add the cookie details if sticky session is enabled.
- You do not need AWS login ID to login to the console to create an AMI from an instance store backed AMI.
- you will need an SSH key, an instance ID and a user's credentials to login to the instance to create a new AMI.
- When an EBS-backed EC2 instance is stopped and the EBS volumes are detached, the alarms on the EBS volume will show the status of Insufficient Data.
- Deleting a subnet with a running instance will not be allowed.
- Taking a snapshot from standby Replica will not help reduce latency caused by the Multi AZ feature in a small RDS MySQL DB.
- 10.0.0.255 cannot be the correct IP address assigned to an instance in a public or private subnet within a VPC with CIDR 10.0.0.0/24.
- 64 unicode characters is the maximum length of a tag key.
- Maximum value of a tag value length is 256 unicode characters.
- An IAM role attached to the organization's authentication service is the best solution for providing access to various AWS services for a large organization.
- Defining launch permissions is not a step performed while creating an AMI from an instance store backed AMI.
- ELB connection draining helps stop sending new requests traffic to an instance while continuing in-flight requests.
- s3:DeleteObject permissions in an S3 policy are equivalent to WRITE ACL Permission on a bucket.
- Using CLI, you can schedule autoscaling group only up to 30 days in advance.
- Auto Scaling will through an error if two conflicting schedules (daily and monthly) are set up.
- DiskReadBytes will always display a 0 value in CloudWatch monitoring on an EBS backed EC2 instance.
- You can define tags on the Development and production servers and add a condition to the IAM Policy for improved security in a VPC with production and development instances.
Azure
- To restrict MFA to only connections to the Exchange Online mailbox, you need to configure Azure MFA for the specific service principal used to connect to Exchange Online.
