Which statement is true about the use of dead peer detection (DPD) within an IPsec environment?

. DPD and Cisco IOS keepalives are sent together.

. DPDs are sent at regular intervals.

. DPDs are sent when no traffic is flowing.

. DPDs are sent by default only when the IKE policy is initiated.

. The hash algorithm used will be MD5.

. The lifetime will be unlimited.

. Pre-share authentication will be used.

. 3DES encryption will be used.

Which two modes can be selected after launching the Create a Site-to-Site VPN option using the SDM? (Choose two.)

Refer to the exhibit. Which task would specify additional security by authenticating the user of a remote VPN device?
