A. The TTL field from the IP packet is copied into the TTL field of the MPLS label header at the ingress
edge LSR.
B. TTL propagation cannot be disabled in an MPLS domain.

4. Two routers configured to run BGP have been connected to a firewall, one on the inside interface and
one on the outside interface. BGP has been configured so the two routers should peer, including the
correct BGP session endpoint addresses and the correct BGP session hop-count limit (EBGP multihop).
What is a good first test to see if BGP will work across the firewall?
A. Attempt to TELNET from the router connected to the inside of the firewall to the router connected to the
outside of the firewall. If telnet works, BGP will work, since telnet and BGP both use TCP to transport
data.
B. Ping from the router connected to the inside interface of the firewall to the router connected to the
outside interface of the firewall. If you can ping between them, BGP should work, since BGP uses IP to
transport packets.
C. There is no way to make BGP work across a firewall without special configuration, so there is no
simple test that will show you if BGP will work or not, other than trying to start the peering session.
D. There is no way to make BGP work across a firewall.
Answer: A
