NEW QUESTION # 18
You have a Deployment running a database application with a stateful application using a StatefulSet. How can you scale the database to handle increased read traffic without impacting the write performance for the stateful application?
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
1. Use a Read Replica:
- Create a read replica of the database that replicates data from the primary database.
- Use the read replica for read-only operations to distribute the read load.
2. Configure the StatefulSet:
- Configure the StatefulSet to access the read replica for read-only operations.
- Use a separate Service for the read replica and configure the StatefulSet to access it.
3. Implement a Load Balancer:
- Use a Load Balancer to direct read traffic to the read replica and write traffic to the primary database.
- Configure the Load Balancer to use a specific port for read requests and another port for write requests.
4. Monitor Performance:
- Monitor the performance of both the primary database and the read replica.
- Ensure that the read replica is adequately handling the read load without impacting the write performance on the primary database.
5. Scale Read Replicas:
- If necessary, scale the number of read replicas to handle increased read traffic.
- Add more read replicas as needed and adjust the Load Balancer configuration to distribute the traffic evenly.

* Add an init container to hungry-bear (which has been defined in spec file
/opt/KUCC00108/pod-spec-KUCC00108.yaml)
* The init container should create an empty file named/workdir/calm.txt
* If /workdir/calm.txt is not detected, the pod should exit
Answer:
Explanation:
* Once the spec file has been updated with the init container definition, the pod should be created See the solution below.

NEW QUESTION # 22
Describe the difference between 'ReadWriteOnce' and access modes for PersistentVolumeClaims. In what scenarios would you choose each?
Answer:
Explanation:
See the solution below with Step by Step Explanation.
Explanation:
Solution (Step by Step) :
ReadWriteOnce:
- Description: This mode allows only one pod to mount the volume at a time.
- Scenarios: Ideal for applications requiring exclusive access to the storage, such as databases where data integrity is crucial. Examples include:
- Single-instance databases (e.g., MySQL, PostgreSQL)
- Applications that modify files concurrently and need to ensure consistency.
ReadWriteMany:
- Description: This mode allows multiple pods to mount the volume simultaneously.
- Scenarios: Suitable for applications that need shared access to data, such as shared storage for applications, I configuration files, or log files. Examples include:
- Shared file systems (e.g., NFS, GlusterFS)
- Applications where multiple pods need to access the same data simultaneously.
