The access list should not contain more than three (3) statements and should be applied to the Cisco Highway1 router. The routers have been previously configured with the following specifications.
- The router are named Cisco Highway1, Cisco Highway2 and Cisco Highway3.
- RIP is the routing Protocol.
- Clocking is provided on the Serial 0 Interfaces.
- The password on each router is "Cisco Highway".

QUESTION 325 A Cisco Highway trainee is curios about ISL and 802.1q Frame Tagging, and asks you what is the purpose of these. What should you tell the Cisco Highway trainee?
A. They Provide Best Path Determination.
B. They Allow the Exchange of filtering tables.
C. They Specify different Implementations of the Spanning-Traa Protocol.
D. They Provide Interswitch VLAN Communication. Answer: D Explanation: A trunk link is the other type of Layer 2 port supported on Cisco switches. When a trunk port is configured, it begins marking frames as they exit the port to indicate which VLAN each frame is associated with. The trunk port can also read the markings, called tags, as they enter the trunk port. This enables the switch to send a frame only to the ports for the given VLAN associated with the incoming frame. The main purpose of trunking is to carry traffic between switches and maintain the VLAN information. Unlike an access link, the trunk link does not belong to a single VLAN but instead can carry traffic from several VLANs over a point-to-point link between two devices that understand the protocol. Because a trunk is typically a point-to-point connection between two switches, it is very efficient and highly recommended that it runs in full-duplex mode. Figure 3-6 shows trunk Links between switches carrying traffic for multiple VLANS. Two forms of trunking are used for Cisco switches on Ethernet networks: An IEEE industry standard called IEEE 802.1Q. This is a frame-tagging mechanism that adds a VLAN identifier to the frame by inserting a tag at Layer 2. Another form of trunking on Cisco switches is called Inter-Switch Link (ISL), which is a Cisco proprietary trunking mechanism. ISL uses a frame encapsulation method that adds a header to identify the VLAN.
