What is the purpose of port 197?

  1. Simple Network Paging Protocol

  2. Directory Location Service

  3. Gateway Access Control Protocol

  4. IKE Internet Key Exchange

The correct answer is: Directory Location Service

The purpose of port 197 is indeed associated with the Directory Location Service, which plays a critical role in managing and facilitating directory services in various network environments. This service is vital for helping systems locate directories and obtain necessary information about network resources, which can enhance overall network efficiency and resource accessibility. In particular, the Directory Location Service utilizes port 197 to receive and process requests, allowing clients to query directory information effectively. This aids in scenarios where directory services are used for accessing user data or other network resources, making it an essential part of network management. Understanding the role of specific ports in communication protocols reinforces the significance of network configuration for security analysts and IT professionals, as it aids in identifying traffic patterns and potential vulnerabilities.
