Configure IP addresses, subnet masks, and gateway addresses on routers and hosts
Configuring the IP address and subnet mask on a Cisco router is done with one easy command. Read the rest of this entry »
Now we are in the meat of it. Part one of the objectives tended toward theoretical information. Now we are into the objectives that uses verbs like implement, configure, and customize. This is going to be a long one, so get comfortable.
Configure routing protocols given user requirements
The principle job of a router is to take in a packet, figure out where to send it next to get it closer to its destination, and send it out the appropriate interface. To do this, a router is configured with or builds a routing table containing network addresses and how to route to those networks (either by IP address or router interface). The majority of this objective, and a good part of the CCNA exam, is related to configuring a router to dynamically build the routing table.

Access lists provide a powerful mechanism for restricting what network traffic can flow through a router and can be used for other purposes like identifying interesting traffic for dial on demand routing, prioritizing traffic for quality of service, and network address translation.
Develop an access list to meet user specifications
Implementing access lists comes down the road in objective 2.10. For now, it is only important to understand the types of access lists, their uses, and their overall design.

Internetworking involves the connection of two or more networks. Wide Area Networking (WAN) handles these connections.
Design a simple internetwork using Cisco technology
Select an appropriate routing protocol based on user requirements
David Davis has a concise review of selecting routing protocols describing their strengths and weaknesses, their ideal topologies, and a brief description of how they work.
The CCNA exam is likely to wear you out working on IP addressing and subnetting questions. Be prepared for them by understanding this topic thoroughly. Work lots of various examples to hone your skills and your speed. The faster you can get these done (correctly), the more time you’ll have for things that are more challenging.
Design an IP addressing scheme to meet design requirements
Local Area Network (LAN) technology these days is mostly wired Ethernet and wireless technologies. For the purposes of the CCNA exam, Ethernet knowledge should be all that is needed.

Woop! We’ve completed our first certification exam guide, the Sun Certified System Administrator for the Solaris 10 OS part I exam, 310-200. We hope this is the first of many guides and that it helps in your preparation for the exam. Please leave feedback and comments on the site in general and the coverage of the exam objectives in particular. If you find a resource on a topic that you feel does a better job of explaining an objective, please let us know and we’ll check it out and incorporate it into the guide if it is appropriate.
Enjoy your journey and good luck on your exam!
Restore data from a UFS snapshot and delete the UFS snapshot.
This is a misleading objective in some ways, although it makes an important point. A UFS snapshot is simply a temporary copy of a filesystem, a snapshot in time of a live filesystem. Read the rest of this entry »
Traditional UFS backup tools (like ufsdump) cannot do their job effectively with a busy, mounted, multiuser filesystem. The fssnap utility provides the capability to create a temporary copy (UFS snapshot) of an active, mounted filesystem which can then be backed up using ufsdump or other tools.
Backup a mounted file system by creating a UFS snapshot and performing a backup of the snapshot file.
