A network administrator is adding two new hosts to SwitchA. Which three values could be used for the configuration of these hosts? (Choose three.)

A. host A IP address: 192.168.1.79
B. host A IP address: 192.168.1.64
C. host A default gateway: 192.168.1.78
D. host B IP address: 192.168.1.128
E. host B default gateway: 192.168.1.129
F. host B IP address: 192.168.1.190

Answer : A, C, F

Explanation:

Refer to the exhibit. Host A connected to Port 6 and Host B connected to Port 9. Also Port 6 and Port 9 associated with VLAN10 AND VLAN 20 respectively.
In router Rtr1, the sub-interface fa0/0.10 and fa0/0.20 ‘s IP address will be used for Default Gateway for Host A and Host B.

First take the IP address of fa0/0.10 – 192.168.1.78 /27 (255.255.255.224)
Its IP range will be 192.168.1.65 – 192.168.1.94
Network Address – 192.168.1.64, Broadcast Address – 192.168.1.95

Second take the IP address of fa0/0.20 – 192.168.1.130 /26 (255.255.255.192)
Its IP range will be 192.168.1.129 – 192.168.1.190
Network Address – 192.168.1.128, 192.168.1.191


Now the Answers:

A. host A IP address: 192.168.1.79 – The IP address 192.168.1.79 is in the IP range of VLAN10. So this IP address can be assigned to Host A.

B. host A IP address: 192.168.1.64 – The IP address 192.168.1.64 is the network address. So incorrect choice.

C. host A default gateway: 192.168.1.78 – The IP address of Rtr1’s fa0/0.10 = 192168.1.78. So the IP address 192.168.1.78 must be default gateway for Host B.

D. host B IP address: 192.168.1.128 – The IP address 192.168.1.128 is the network address. So incorrect choice.

E. host B default gateway: 192.168.1.129 - The IP address of Rtr1’s fa0/0.10 = 192168.1.190. So the IP address 192.168.1.190 must be default gateway for Host B. Not 192.168.1.129.

F. host B IP address: 192.168.1.190 - The IP address 192.168.1.190 is in the IP range of VLAN20. So this IP address can be assigned to Host A.

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...

Access Control List (ACL) Simlet

An administrator is trying to ping and telnet from Switch to Router with the results shown below: For this question we only need to use the show running-config command to answer all the questions below: Router>enable Router#show running-config   Question 1 Which will fix the issue and allow ONLY ping to work while keeping telnet disabled? A. Correctly assign an IP address to interface fa0/1 B. Change the ip access-group command on fa0/0 from “in” to “out” C. Remove access-group 106 in from interface fa0/0 and add access-group 115 in. D. Remove access-group 102 out from interface s0/0/0 and add access-group 114 in E. Remove access-group 106 in from interface fa0/0 and add access-group 104 in Answer : E Explanation: The question was not about FTP so skip line #1 and line #2. The line #3 denies telnet traffic and line #4 permits icmp-echo traffic. L...

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...
