2). Cisco Routing: "ip default-network" vs. Default Static Routes By : Chris Bryant, CCIE #12933
One point of confusion for some CCNA and CCNP candidates is the difference between configuring a static default route and using the Cisco routing command ip default-network. At first glance, they appear to do the same thing. Both configure a destination to which packets should be routed if there is no more specific route in the routing table. The.

4). Cisco CCNA Exam Tutorial: Configuring Standard Access Lists By : Chris Bryant, CCIE #12933
Access Control Lists (ACLs) allow a router to permit or deny packets based on a variety of criteria. The ACL is configured in global mode, but is applied at the interface level. An ACL does not take effect until it is expressly applied to an interface with the ip access-group command. Packets can be filtered as they enter or exit an interface. If a packet enters or exits an interface with an ACL applied, the packet is compared against the criteria of the ACL.

14). Cisco CCNA Certification: How And Why Switches Trunk By : Chris Bryant, CCIE #12933
Your CCNA studies are going to include quite a bit of information about switches, and for good reason. if you don't understand basic switching theory, you can't configure and troubleshoot Cisco switches, either on the CCNA exam or in the real world. That goes double for trunking! Trunking is simply enabling two or more switches to communicate and send frames to each other for transmission to remote hosts.
