Hi guys, SNMP v3 question please

drek47

You have implemented SNMP v3 in your network. You find after making the configuration changes that technicians in the RESTRICTED group cannot access the MIB. You execute the show run command and receive the following output that relates to SNMP:

output omitted

snmp-server group NORMAL v3 priv read NORMAL write NORMAL
snmp-server group RESTRICTED v3 priv read RESTRICTED access 99
snmp-server group TRAP v3 priv

!!
snmp-server user NORMAL NORMAL v3 auth sha CISCO priv des56 CISCO
snmp-server user RESTRICTED RESTRICTED v3 auth sha CISCO priv des56 CISCO
snmp-server user TRAP TRAP v3 auth sha CISCO priv des56 CISCO

snmp-server enable traps snmp linkup linkdown
snmp-server host 155.1.146.100 traps version 3 priv TRAP

What is preventing the RESTRICTED group from viewing the MIB?

[color=rgb(0, 0, 0) !important]

A The presence of the keyword auth in the command creating the RESTRICTED user.

B The presence of the keyword priv in the command creating the RESTRICTED group.

C A mismatch between the authentication mechanism and the encryption type in the command creating the RESTRICTED user.

D The absence of an access list defining the stations that can used by the RESTRICTED group.
