The modern NMS system has been configured with IP address 172.14.15.1, and the snmp- server view iso included command has already been added to the template.
Which two commands should the team add to the configuration template to enable SNMPv3 on network devices? (Choose two.)
A. snmp-server user Cisco group v3 auth md5 Cisco123 authpriv aes 192 Cisco1234
B. snmp-server group v3 authnopriv ro
C. snmp-server user Cisco group v3 auth sha Cisco123 priv aes 256 Cisco1234
D. snmp-server user Cisco group v3 auth she-aes Cisco123 authnopriv aes 128 Cisco1234
E. snmp-server group v3 priv read view -

C. R1 can failover to any peer.
D. R1 can failover only to a peer that is configured for LDF SSO/NSF. -
Question 328:

A. implement OSPF to maintain the link-state database during failover.
B. implement VRFs ana specify the forwarding instances that must remain active during failover.
C. implement an L2VPN with the failover peer to share state Information between the active and standby devices.
D. implement Cisco Express Forwarding to provide forwarding during failover -
Question 329:

A. DHCP
B. RPC
C. NETCONF
D. TFTP -
