If a certificate authority trustpoint is not configured when enabling HTTPS and the remote HTTPS
server requires client authentication, connections to the secure HTTP client will fail. Which
command must be enabled for correct operation?

A.
ip http client secure-ciphersuite 3des-ede-cbc-sha

B.
ip https max-connections 10

C.
ip http timeout-policy idle 30 life_120 requests 100

D.
ip http client secure-trustpoint trustpoint-name

Explanation:
IP http client secure-trustpoint
To specify the remote certificate authority (CA) trustpoint that should be used if certification is
needed for the secure HTTP client, use the ip http client secure-trustpoint command in global
configuration mode. To remove a client trustpoint from the configuration, use the no form of this
command.
IP http client secure-trustpoint trustpoint-name
