Question 7: On Cisco routers, there are two mutually exclusive types of RSA key pairs: special-usage keys
and general-purpose
keys. When you generate RSA key pairs, you are prompted to select either special-usage keys or
general-purpose
keys. Which set of statements is true?
A. If you generate special-usage keys, two pairs of RSA keys are generated. One pair is used with any
IKE policy that
specifies RSA signatures as the authentication method. The other pair is used with any IKE policy that
specifies RSA
encrypted keys as the authentication method.
B. If you generate a named key pair, only one pair of RSA keys is generated. This pair is used with IKE
policies that
specify either RSA signatures or RSA encrypted keys. Therefore, a general-purpose key pair might be
used more
frequently than a special-usage key pair.
C. If you generate general-purpose keys, you must also specify the usage-key keyword or the general-
key keyword.
Named key pairs allow you to have multiple RSA key pairs, enabling the Cisco IOS Software to
maintain a different key
pair for each identity certificate.
D. special-usage key pair is default in Cisco IOS
