How does an Edge support Disaster Recovery?

• A. By recording all calls for a month
• B. By using a snapshot for operations continuity
• C. By providing telephony services only
• D. By ensuring all calls are routed via SIP

Answer: (B)

The Edge supports Disaster Recovery by utilizing a snapshot for operational continuity. This functionality allows the system to maintain an up-to-date image of its configuration and state, enabling rapid recovery in the event of a failure or disaster. Snapshots are important because they ensure that critical data and configurations are not lost, which can be essential for restoring services quickly and minimizing downtime.

In the context of a Disaster Recovery plan, using a snapshot ensures that all necessary information is available to bring the system back to its operational state as it was before the disruption. This capability is crucial for maintaining business continuity and providing a seamless experience for users.

Other options, while potentially relevant in different contexts, do not provide the same level of support for Disaster Recovery. Recording calls may be useful for compliance and quality assurance but does not assist in restoring operations after disruption. Telephony services being provided alone does not equate to a robust disaster recovery strategy, as it lacks the critical mechanisms required for operational recovery. Lastly, routing calls via SIP is essential for maintaining communication, but it does not inherently include any disaster recovery features, such as the snapshot capability that ensures data resilience and operational continuity.
