Which of the following elements should be tested when deploying cloud based services? (Select two.)

Bandwidth testing is critical to ensure that the cloud service can handle the expected data transfer rates to and from users and other services without bottlenecks.

Caching effectiveness should be tested to verify that frequently accessed data is being stored and delivered efficiently, reducing latency and load on origin servers.

Application performance testing measures how well the application responds under various loads, ensuring it meets service level agreements (SLAs) and provides a satisfactory user experience.

Virtual routers are infrastructure components that are typically configured and validated as part of the cloud provider's network services or infrastructure-as-code deployment, rather than a direct element tested for application performance after deployment.

Jumbo frames are a network configuration feature that may be relevant to underlying infrastructure but are not a primary application-level element typically tested for general cloud service deployment performance.
