Which transport layer protocol is used to form LDP sessions?

1. A. UDP
2. B. SCTP
3. C. TCP
4. D. RDP

Correct Answer: C
LDP multicasts hello messages to a well-known UDP port (646) in order to discover neighbors. Once the discovery is accomplished, a TCP connection (port 646) is established and the LDP session begins. LDP keepalives ensure the health of the session. Thanks to the LDP session, LDP messages create the label mappings required for a FEC. Withdraw messages are used when FECs need to be torn down.

Which Ipv6 first-hop security feature helps to minimize denial of service attacks?

1. A. IPv6 Router Advertisement Guard
2. B. IPv6 Destination Guard
3. C. DHCPv6 Guard
4. D. IPv6 MAC address filtering

Correct Answer: B
The Destination Guard feature helps in minimizing denial-of-service (DoS) attacks. It performs address resolutions only for those addresses that are active on the link,and requires the FHS binding table to be populated with the help of the IPv6 snooping feature.The feature enables the filtering of IPv6 traffic based on the destinationaddress, and blocks the NDP resolution for destination addresses that are not found in the binding table. By default, the policy drops traffic coming for an unknowndestination.
