R3 is the key server in a GETVPN VRF-Aware implementation. the group members for the site a register with key server via interface address 10.1.20. 3/24 in the management VRF "mgmt". The GROUP ID for the site a is 100 to retrieve group policy and keys from the key server.

The traffic to be encrypted by the site a group members is between 192.186.4.0/24 and 192.186.5.0/24. The preshared key used by the group members to authenticate with the key server is "cisco”. It has bee reported that group members cannot perform encryption for the traffic defined in the group policy of site a.

Which two possible issues are true? (Choose two)
A . The registration interface is not part of management VRF "mgmt”
B . incorrect encryption traffic defined in the group policy
C . incorrect encryption in ISAKMP policy
D . incorrect password in the keyring configuration
E . The GDOI group has an incorrect local server address
F . incorrect security-association time in the IPsec profile


Answer: AB
