HW has a Frame Relay network with two sites (a headquarters site and a remote site) connected by a single PVC. RIP version 2 is running in the network. A new remote site is added and HW has ordered a second PVC between this site and the headquarters site. All Frame Relay interface IP addresses are in a single subnet. The customer configured Frame Relay DLCI mappings and can successfully ping from the new remote to the headquarters site as well as to the other remote site. However, the new router does not have a route in its route table to the other remote site's LAN, and cannot ping the LAN interface or any hosts on that LAN. What is most likely causing the problem?

The headquarters site router has split-horizon enabled on the frame-relay interface

Triggered updates should be configured on the headquarters router, to directly forward routing updates between the two remote sites

The headquarters site router has split-horizon enabled on the frame-relay interface

Neighbor statements are not configured on the two remote sites, pointing to all other sites

The frame-relay IP to DLCI mappings are incorrectly configured

RIP cannot propagate routing updates over a partial mesh frame-relay configuration, so another routing protocol should be selected

Which of the following statements are NOT true regarding the TCP sliding window protocol? (Multiple Choice)

The initial window offer is advertised by the sender

The receiver is required to acknowledge the data packets transmitted by the sender

The sender need not transmit a full window's worth of data

The initial window offer is advertised by the sender

If the retransmission timer expires without the sender receiving an ACK message, the receiver retransmits the packet to the sender.

It allows the transmission of multiple frames before waiting for an acknowledgment

The receiver is required to acknowledge the data packets transmitted by the sender

The sender need not transmit a full window's worth of data

Which of following statements is true about IS-IS LDP synchronization?

LDP synchronization can be enabled globally

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?

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

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, other than trying to start the peering session.

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

There is no way to make BGP work across a firewall

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.
