Which Types of Information Does Cisco Expressway Back Up?

DE.

Cisco Expressway is a solution that provides secure remote access for external users to Cisco Collaboration infrastructure, including voice, video, and messaging services. It acts as an edge gateway that bridges the gap between the internal and external networks, and ensures secure communication between them.

Regarding the backup of Cisco Expressway, the solution provides backup and restore procedures to ensure that critical data is not lost in case of a failure or disaster. The backup process creates a snapshot of the current configuration and data, which can be used to restore the system to its previous state.

In this context, the types of information that Cisco Expressway backs up are as follows:

1. Security certificates: Cisco Expressway uses security certificates to ensure secure communication between internal and external networks. These certificates are used to encrypt and decrypt data, and to authenticate users and devices. Backing up security certificates ensures that they can be restored in case of a failure or loss, and that secure communication can be maintained.

2. Log files: Cisco Expressway generates log files that contain information about the system's operation, events, and errors. These log files are important for troubleshooting and auditing purposes, and can be used to identify and diagnose issues with the system. Backing up log files ensures that they can be accessed and analyzed in case of a failure or problem.

Therefore, the correct answers to the question are B. log files, and E. security certificates. Cisco Expressway does not back up call records, IP addresses, or current call states as they are dynamic and change frequently during operation.
