Selected Answer: BE
Answer: BE For a traversal zone to establish a connection between Expressway-C and Expressway-E, the authentication credentials used by the two systems must match. This typically involves configuring the authentication method and credentials for both zones to ensure they are correctly aligned and can successfully authenticate each other. The error message “user not found” suggests that Expressway-E is trying to authenticate a user or credentials that are not present in its local database. The engineer should ensure that the correct user (or credentials) exist in Expressway-E's local database for the authentication to succeed.
