2. You just installed a new router (RTR07) in a field office. As part of the initial setup, you want to configure a description for the eighth gigabit Ethernet interface. Which of the following would set the description to WAN to Main Office?

• RTR07(config)#int gi0/8 RTR07(config)#int description WAN to Main Office
• RTR07(config)#int gi0/8 RTR07(config)#description WAN to Main Office
• RTR07(config)#int gi0/8 set description WAN to Main Office
• RTR07>int gi0/8 RTR07>description WAN to Main Office

3. How does configuring banners add to the security of your router?

• Banners identify allowed traffic by protocol or source or destination address, allowing you to control which devices or applications have access.
• Banners encrypt passwords, making them impossible to recognize and difficult to crack.
• Banners obscure the intended use of the device, making it harder for attackers to perform reconnaissance attacks.
• Banners turn on password checking, allowing only those with the correct password to gain access to the router.
• Banners provide a notice of intent, informing users that access is controlled or that activity may be logged.

4. The administrator of a corporate network is receiving complaints from internal users that they cannot access the internet. The administrator displays the routing table of the local router using the show ip route command.

What should the administrator do on the local router to provide internal users access to the internet?

• Disable RIP and enable IGRP as the routing protocol
• Obtain a routable address for use on the internet
• Configure a default route using ip route 0.0.0.0 0.0.0.0 131.108.2.2
• Disable RIP and use a Link-State Routing Protocol

5. You are setting up a wireless hotspot in a local coffee shop. For best results, you want to disperse the radio signals evenly throughout the coffee shop.
