3Refer to the exhibit. After the listed commands are entered into router R1 and switch S1, PC1 and PC2 cannot ping each other. Thenetwork administrator enters the show interfaces trunk command and gets the results that are shown. What is the likely problem?The router has not been configured with a routing protocol.The trunk is established, but no VLANs have been configured to use it.The trunk has not been established because the switch port has not been configured for trunking.The switch, the router, or both must be configured with the dynamic desirable option for the Dynamic Trunking Protocol toestablish a trunk.4 Which statement is true about open authentication when it is enabled on an access point?requires no authenticationuses a 64-bit encryption algorithmrequires the use of an authentication serverrequires a mutually agreed upon password5 What happens when the crypto key zeroize rsa command is entered on a switch configured with the transport input ssh command onthe vty lines?A new RSA key pair is created.The switch defaults to allowing Telnet connections only.
