Q1. How mpls ping works
Ans. 
MPLS ping is a tool used to test connectivity between two MPLS-enabled devices by sending ICMP echo requests.
• MPLS ping works by encapsulating ICMP echo requests within MPLS packets.

• It uses the MPLS label stack to route the packets through the network.

• The receiving device responds with an ICMP echo reply, allowing the sender to verify connectivity.

• MPLS ping is commonly used for troubleshooting MPLS networks and verifyin

Q4. How does SSL pinning works?
Ans. 
SSL pinning is a security technique that ensures a client only communicates with a server using a pre-defined public key.
• SSL pinning involves hardcoding the server's public key in the client's code or configuration.

• During the SSL handshake, the client checks if the server's public key matches the pinned key.

• If the keys match, the connection is established; otherwise, it is rejected.

• Pinning prevents man-in-the-middle at

Q6. Where to save encription key?
Ans. 
Encryption keys should be securely stored in a separate key management system.
• Encryption keys should not be stored alongside the encrypted data.

• Use a dedicated key management system (KMS) to store and manage encryption keys.

• Implement strong access controls and authentication mechanisms for the KMS.

• Consider using hardware security modules (HSMs) for added security.

• Regularly rotate encryption keys to minimize the impact
