Which of these statements best describes the major difference between an IPv4-compatible tunnel and a 6to4 tunnel?

Which information is carried in an OSPFv3 intra-area-prefix LSA?

Which IPv6 address would you ping to determine if OSPFv3 is able to send and receive unicast packets across a link?

What does a unicast prefix-based IPv6 multicast address start with?

How does an IPv6 router deal with a packet that is larger than the outgoing interface MTU?

Which of the following is true about the MPLS header and its EXP field size?

A network is composed of several VRFs. It is required that VRF users VRF_A and VRF_B be able to route to and from VRF_C, which hosts shared services.
However, traffic must not be allowed to flow between VRF_A and VRF_B. How can this be accomplished?

A request arrived on your MPLS-vpn-bgp group. Due to a security breach, your customer is experiencing DoS attacks coming from specific subnets (200.0.10.0/24,
200.0.12.0/24). You have checked all MPLS-EBGP routes being advertised to BHK from other VPN sites and found four subnets listed: 200.0.10.0/24,
200.0.11.0/24, 200.0.12.0/24, 200.0.13.0/24. You immediately apply an outbound ACL filter using the appropriate MPLS-EBGP tool: access-list 1 deny 200.0.10.0
255.255.254.0 access-list 1 permit any What happens when you apply this ACL on the MPLSEBGP connection to BHK?

Multi Protocol Label Switching (MPLS) is a data-carrying mechanism that belongs to the family of packet-switched networks. For an MPLS label, if the stack bit is set to1, which option is true?

For which routes does LDP advertise a label binding?
