Answer:
D) crypto key generate rsa
Step-by-step explanation:
In cryptography, the RSA refers to Rivest–Shamir–Adleman. This is an algorithm used for encrypting and decrypting messages in computers thereby ensuring secured transmission of data. In order to generate an RSA key pair, you will use the command crypto key generate rsa while in the global configuration mode. This command has the following syntax:
crypto key generate rsa [general-keys| usage-keys| signature| encryption] [labelkey-label] [exportable] [modulus modulus-size] [storage name of device:][redundancy][on name of device:],
with each parameter having its description
