Based on the output from RouterA, what are two possible reasons for the failure?

Refer to the exhibit.

322


Hosts in network 192.168.2.0 are unable to reach hosts in network 192.168.3.0.
Based on the output from RouterA, what are two possible reasons for the failure?(Choose two)

A. The cable that is connected to S0/0 on RouterA is faulty.
B. Interface S0/0 on RouterB is administratively down.
C. Interface S0/0 on RouterA is configured with an incorrect subnet mask.
D. The IP address that is configured on S0/0 of RouterB is not in the correct subnet.
E. Interface S0/0 on RouterA is not receiving a clock signal from the CSU/DSU.
F. The encapsulation that is configured on S0/0 of RouterB does not match the encapsulation that is configured on S0/0 of RouterA.

Answer : E, F

E: If no clock rate found on DCE end or no keepalive message received , then the Protocol Status changed to down.
F: Also if RouterA Serial0/0 and RouterB Serial S0/0 configured with two different protocols (Example: HDLC, PPP), then Protocol status will be changed to down.

Incorrect Choices

A, B: If cable is faulty or RouterB S0/0 is administratively down, then Status of RouterA S0/0 also in down.
C, D: If incorrect IP address and Subnet mask configured, the protocol status or physical status never on down state.

Cisco Packet Tracer Multi User Connection

Multiuser communication allows multiple point-to-point (peer) connections between multiple instances of Packet Tracer. By allowing communication between Packet Tracer instances, a new door has been opened to a fun, interactive, social, collaborative, and competitive learning environment. Instructors will now be able to create a variety of activities for students to learn in groups that will facilitate greater social interaction between students. Students will benefit from this environment by working together to solve problems and share ideas. Both students and teachers should take full advantage that Multiuser will offer in their learning environment. Technical Information Communicates between instances using PTMP. PTMP is TCP based. By default, uses TCP port 38000, is customizable, and each new instances on the same PC will use the next available port. On by default. UPnP will attempt to establish port forwarding to facilitate home networks. All network co...

Host A pings interface S0/0 on router 3. What is the TTL value for that ping?

Refer to the exhibit. Host A pings interface S0/0 on router 3. What is the TTL value for that ping? A. 252 B. 253 C. 254 D. 255 Answer : B Explanation: The TTL or Time-To-Live gives you an indication of the number of routers between the source and destination. The TTL is used to prevent an IP packet from looping inside an IP network and causing a network meltdown. The initial TTL packet value for an IP packet is 255 and then it is decremented by 1 each time it encounters a router. When this value reaches 0, the packet is discarded by a router. The TTL value is contained in each IP packet including ICMP packets. The TTL value given by the ping command is in fact the TTL value of an echo_response packet. By default, Windows will decrease the TTL by 128 and Ubuntu Linux by 192. The above the exact topology of this questions. I used 10.0.0.1 for Host A’s IP address and 12.0.0.2 for R3 S0/0’s IP address. All router has been config...
