2. Increased latency
3. Filtering of collision fragments only
4. None of the above

142. Which action will allow telnet traffic from a user’s PC to a router using TCP/IP?

1. Connect the PC’s COM port to the router’s console port using a straight-through cable
2. Connect the PC’s COM port to the router’s Ethernet port using a straight-through cable
3. Connect the PC’s COM port to the router’s console port using a crossover cable
4. Connect the PC’s Ethernet port to the router’s Ethernet port using a crossover cable

143. What is the source port size in a TCP header

2. 16 bit
3. 8 bit

144. The corporate head office has a teleconferencing system that uses VOIP (voice over IP) technology. This system uses UDP as the transport for the data transmissions. If these UDP datagrams arrive at their destination out of sequence, what will happen?

1. UDP will pass the information in the datagrams up to the next OSI layer in the order that they arrive.
2. UDP will send an ICMP Information Request to the source host.
3. UDP will use the sequence numbers in the datagram headers to reassemble the data in the correct order.
4. UDP will drop the datagrams.

145. Split horizon has been enabled within the routed network. Which one of the following statements best explains the split horizon rule?

1. Once a route is received on an interface
2. advertise that route as unreachable back out the same interface.Only routers can split boundaries (horizons) between networks in separate AS numbers.
3. Information about a route should never be sent back in the direction from which the original update came.
4. Each AS must keep routing tables converged to prevent dead routes from being advertised across boundaries.

146. You need to determine the proper security settings on a new WLAN-capable office. Which encryption type would WPA2 use in this office?

1. AES-CCMP
2. TKIP/MIC
3. PSK
4. PPK via IV

147. You have just configured a static default route on router PC1 . What is the purpose of a default route?

1. It is a route used when a packet is destined for a remote network that is not listed in the routing table
2. It is a route to be used when the routing protocol fails.
3. It is a route manually configured for a specific remote network for which a routing protocol is not configured
4. It is a route configured by an ISP that sends traffic into a corporate network

148. Which router console commands shown below are used to manage telnet sessions to other routers?

2. D# disconnect 3
3. D# kill connection 1
4. D# exit session 2
