Q2: Your switched network is using Inter-Switch Link (ISL) as VLAN trunking protocol. Which following must be a part of ISL header field?

A. Source Port Number
B. VLAN-ID
C. Destination port number
D. Destination network number

Ans: B
Explanation:
Inter-Switch Link (ISL) is one of the VLAN trunking protocols used for switched VLAN networks. It uses frame tagging to identify the VLAN. ISL encapsulates the original Ethernet frame, and a VLAN-ID is inserted into the ISL header.

TCP/IP and the OSI Reference Model

As illustrated in Figure 1.2, the TCP/IP model consists of four layers, each of which can have several sublayers. These layers correlate roughly to layers in the OSI reference model and define similar functions. Some of the TCP/IP layers correspond directly with layers in the OSI reference model while other span several OSI layers. The four TCP/IP layers are:

CCNA WAN Questions

Here you will find answers to WAN Questions

Question 1:

The command frame-relay map ip 10.121.16.8 102 broadcast was entered on the router. Which of the following statements is true concerning this command?

A: This command should be executed from the global configuration mode.

B: The IP address 10.121.16.8 is the local router port used to forward data.

C: 102 is the remote DLCI that will receive the information.

D: This command is required for all Frame Relay configurations.

E: The broadcast option allows packets, such as RIP updates, to be forwarded across the PVC.

Correct Answers: E

Explanation:
The command frame-relay map ip 10.121.16.8 102 broadcast means to mapping the distal IP 10.121.16.8 102 to the local DLCI 102. When the "broadcast" keyword is included, it turns Frame Relay network as a broadcast network, which can forward broadcasts

Question 2:

Refer to the exhibit. Which statement describes DLCI 17?

A: DLCI 17 describes the ISDN circuit between R2 and R3.

B: DLCI 17 describes a PVC on R2. It cannot be used on R3 or R1.

C: DLCI 17 is the Layer 2 address used by R2 to describe a PVC to R3.

D: DLCI 17 describes the dial-up circuit from R2 and R3 to the service provider.

Correct Answers: C

Explanation:

DLCI stands for Data Link Connection Identifier. DLCI values are used on Frame Relay interfaces to distinguish between different virtual circuits. DLCIs have local significance because the identifier references the point between the local router and the local Frame Relay switch to which the DLCI is connected.

CCNA Drag and Drop Questions

Question 1:

A dental firm is redesigning the network that connects its three locations. The administrator gave the networking team 192.168.164.0 to use for addressing the entire netwok. After subnetting the address, the team is ready to assign the addresses. The administrator plans to configure ip subnet-zero and use RIP v2 as the routing protocol. As a member of the networking team, you must address the network and at the same time conserver unused addresses for future growth. With those goals in mind, drag the host addresses on the left to the correct router interface. Once of the routers is partially configured. Move your mouse over a router to view its configuration. Not all of the host addresses on the left are necessary.

Answer:

Explanation:

In short, we should start calculating from the biggest network (with 16 hosts) to the smallest one using the formula 2ⁿ - 2 (n is the number of bits we need to borrow).Therefore:
16 hosts < 2⁵ - 2 (we need to borrow 5 bits -> /27)
11 hosts < 2⁴ - 2 (borrow 4 bits -> /28)
5 hosts < 2³ - 2 (borrow 3 bits -> /29)
From the available ip addresses, we see that each of them has only one suitable solution (they are 192.168.164.149/27,192.168.164.166/28 and 192.168.164.178/29)

The smallest network is the Floss S0/0 which only requires 2 hosts = 2² - 2 (need to borrow 2 bits ->/30). There are 2 suitable answers: 192.168.164.189/30 and 192.168.164.188/30 but notice that 192.168.164.188/30 is the network address so we can not use it (because 188 = 4 * 47) -> we have to choose 192.168.164.189 as the correct solution.
In fact, it is not the formal way to solve a VLSM question so I recommend you to review your CCNA book if you haven't grasped it well yet.

CCNA Troubleshooting Questions 1

Question 1:

Refer to the exhibit. The network administrator is in a campus building distant from Building B. WANRouter is hosting a newly installed WAN link on interface S0/0. The new link is not functioning and the administrator needs to determine if the correct cable has been attached to the S0/0 interface. How can the administrator accurately verify the correct cable type on S0/0 in the most efficient manner?

A. Telnet to WANRouter and execute the command show interfaces S0/0
B. Telnet to WANRouter and execute the command show processes S0/0
C. Telnet to WANRouter and execute the command show running-configuration
D. Telnet to WANRouter and execute the command show controller S0/0
E. Physically examine the cable between WANRouter S0/0 and the DCE.
F. Establish a console session on WANRouter and execute the command show interfaces S0/0

Answer: D

Explanation:

The show controller command displays the information about the physical interface itself and the type of serial cable plugged into a serial port. In this case, it should be a DTE cable that plugs into a type of data service unit (DSU).
For your understanding, below is the output of this command:

From the output, we notice that serial 0/0 has a DTE cable and would get its clocking from the DSU.

CCNA 2 - Final Exam: A

• The packet will match the 192.168.0.0 network and be forwarded out Serial 0/0.
• The packet will most closely match the 192.168.0.8 subnet and be forwarded out Serial 0/1.
2. Which three statements are true of holddown timers? (Choose three.)
• used by link state routing protocols to prevent routing loops
• prevent update messages from reinstating a route that may have gone bad
• allow routers to still forward packets to destination networks that are in holddown
• limit the number of hops a packet can traverse through the network before it is discarded
• prevent a router advertising a network through the same interface from which the network was learned
• permit lower metric updates received from any neighboring router to reinstate the route to a possibly down Network
3. What command would the network administrator apply to a router that is running OSPF to advertise the entire range of addresses included in 172.16.0.0/19 in area 0?
