it´s B

R1(config-if)#ipv6 traffic-filter ? WORD Access-list name R1(config-if)#ipv6 traffic-filter

i concur, its B

Answer is B

the answer corret is B: Line vty: acces-class line interface: traffic-filter https://www.cisco.com/c/en/us/td/docs/ios/ipv6/command/reference/ipv6_book/ipv6_05.html#wp2274594

Im going with C, hence its denied and permitted the telnet traffics, so this ACl must be applied under the VTY lines, so for VTY line we must use Applying an IPv6 ACL to the Virtual Terminal Line SUMMARY STEPS 1. enable 2. configure terminal 3. line [aux| console| tty| vty] line-number[ending-line-number] 4. ipv6 access-class ipv6-access-list-name {in| out} https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_data_acl/configuration/xe-16/sec-data-acl-xe-16-book/ip6-acls-xe.html

B, because is talking about incesary traffic for the interface. Access Class is for apply Line vty ACL.

B is right https://community.cisco.com/t5/network-security/ipv6-access-class-vs-ipv6-traffic-filter/td-p/1510357#:~:text=The%20%27ipv6%20access-class%27%20command%20is%20used%20to%20filter,%28i.e.%20management%20traffic%29.%20Command%20reference%20%28with%20example%29%3A%20http%3A%2F%2Fwww.cisco.com%2Fen%2FUS%2Fdocs%2Fios%2Fipv6%2Fcommand%2Freference%2Fipv6_05.html%23wp2274594
