   A security team wants to enforce that only service A can call service B, and all communication must be encrypted. They are using a service mesh. Which configuration should they apply?

   • AUse Kubernetes NetworkPolicies to restrict ingress to service B and rely on the application to use HTTPS.
   • BConfigure a ServiceEntry for service B and set the traffic policy to allow all traffic.
   • CDefine an AuthorizationPolicy that allows traffic from service A to service B, and enable mTLS in the mesh.
   • DEnable automatic sidecar injection and set the destination rule to use plain HTTP.

   A company has a small microservices environment and is considering a service mesh. They are concerned about the operational overhead. What is a reasonable approach?

   • AUse a service mesh only for security and ignore traffic management features.
   • BAvoid service mesh entirely because it is always too complex for small environments.
   • CStart with a lightweight service mesh or a service mesh that offers a simplified mode, and evaluate the benefits versus the overhead.
   • DAdopt a full-featured service mesh immediately to get all features from the start.
