Which of the following technologies can be used to improve the MPLS BGP VPN reliability?

As shown in the figure, the routers load balances the traffic between Branch network 1 and Branch network 2. In this case, URPF in loose mode must be configured on a physical interface to defend against attacks using spoofed source IP addresses.

Which of the following statements regarding the process in which the source DR registers with the RP on a PIM-SM network is true?

On a BGP/MPLS Ipv4 VPN, OSPF, LDP, and static routes are configured. Which of the following protocols must be enabled with GR to achieve NSF on PEs?

Which of the following statements regarding the processing of BPDUs in 802.1w and 802.1D is true?

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?

On the network shown in the figure below, SW1, SW2 and SW3 are deployed. SW1 is the root bridge, link congestion occurs between SW1 and SW2, and SW2 cannot receive configuration BPDUs sent by the root bridge. Given this information, which of the following spanning tree protection mechanisms needs to be configured to prevent problems caused by link congestion?

Which types of prefixes will a router running BGP most likely advertise to an IBGP peer, assuming it is not configured as a route reflector?

Which of the following statements regarding BGP attributes is true?

Why does RSTP achieve faster convergence than STP?
