   A security team wants to reduce the attack surface of their Spark cluster by ensuring that client machines do not have direct access to the cluster's internal ports. They plan to use Spark Connect. Which additional configuration is required to achieve this?

   • ASet the Spark UI to read-only mode.
   • BConfigure the Spark Connect server to listen only on the internal network and use a reverse proxy or load balancer to expose the endpoint securely.
   • CUse a firewall to block all inbound traffic to the cluster.
   • DEnable TLS encryption on the Spark Connect channel.

   A team is considering using Spark Connect to replace their current architecture where each user runs a local Spark session. They are concerned about the loss of local debugging capabilities. What is the best way to address this concern?

   • AUse Spark Connect in local mode for development and remote mode for production.
   • BAbandon Spark Connect and continue using local Spark sessions.
   • CKeep the local Spark sessions for debugging and use Spark Connect only for production.
   • DUse a remote debugger that attaches to the Spark Connect server.

   A platform team is designing a multi-tenant environment where multiple teams submit Spark jobs to a shared cluster. They need to isolate client environments so that one team's dependency upgrades do not affect another team's ability to submit jobs. Which feature of Spark Connect directly addresses this requirement?

   • AEach client gets a dedicated Spark driver on the server.
   • BThe client and server can be upgraded independently because the client communicates via a stable protocol.
   • CThe server automatically recompiles client code to match its own Spark version.
   • DThe client sends the full application JAR to the server for execution.
