Implementing Microsoft Internet Security and Acceleration (ISA) Server 2004

Candidates for this exam operate in medium to very large networked computing environments that use Microsoft Windows 2000 Server and Microsoft Windows Server 2003 operating systems. Candidates have a basic understanding of Active Directory, DNS, DHCP, WINS, Certificate Services, RADIUS, Routing and Remote Access, FTP, HTTP, HTTPS, TCP/IP, IMAP, POP3, RDP, SMTP, and SSL. They have a minimum of one year’s experience implementing and administering networks and operating systems in environments that have the following characteristics:

Between 50 and 10,000+ supported users.
Multiple physical locations.
Outbound access for typical client services and applications, such as Web access, e-mail, Telnet, FTP, VPN, desktop management, Instant Messaging, and access control policies.
Hosting of network services, such as internal and external Web hosting, messaging, Instant Messaging, RDP, and firewall.
Connectivity requirements that include connecting individual offices and users at remote locations to the corporate network and connecting networks to the Internet.
Using ISA Server firewall and/or caching services in a production environment.

Dynamips / Dynagen

Introduction

Dynamips is a Cisco router emulator written by Christophe Fillot. It emulates 1700, 2600, 3600, 3700, and 7200 hardware platforms, and runs standard IOS images. In Chris’ own words:

This kind of emulator would be useful to:

· Be used as a training platform, with software used in real world. It would allow people to become more familiar with Cisco devices, Cisco being the world leader in networking technologies ;

· Test and experiment features of Cisco IOS ;

· Check quickly configurations to be deployed later on real routers.

Of course, this emulator cannot replace a real router, it is simply a complementary tool to real labs for administrators of Cisco networks or people wanting to pass their CCNA/CCNP/CCIE exams.

Although Dynamips provides a simple virtual switch, it does not emulate Catalyst switches (although it does emulate the NM-16ESW).

Dynagen is a text-based front end for Dynamips, which uses the “Hypervisor” mode for communication with Dynamips. Dynagen simplifies building and working with virtual networks:

* Uses a simple, easy to understand configuration file for specifying virtual router hardware configurations
* Simple syntax for interconnecting routers, bridges, frame-relay and ATM, and Ethernet switches. No need to deal with NetIOs
* Can work in a client / server mode, with Dynagen running on your workstation communicating with Dynamips running on a back-end server. Dynagen can also control multiple Dynamips servers simultaneously for distributing large virtual networks across several machines. Or you can run Dynamips and Dyngen on the same system
* Provides a management CLI for listing devices, starting, stopping, reloading, suspending, resuming, and connecting to the consoles of virtual routers.

Dynagen is written in Python, and is therefore compatible with any platform for which there is a Python interpreter (which is to say, many). The design is modular, with a separate OOP API for interfacing with Dynamips. Other Python applications could be written that use this API for programmatically provisioning virtual networks, or to provide other front-ends. For example, a team is working on GNS-3; a GUI front-end using this library.

Managing and Maintaining a Windows Server 2003 Environment (70-290)

The Microsoft Certified Systems Administrator (MCSA) on Windows Server 2003 credential is intended for IT professionals who work in the typically complex computing environment of medium to large companies. An MCSA candidate should have 6 to 12 months of experience administering client and network operating systems in environments that have the following characteristics:

250 to 5,000 or more users
Three or more physical locations
Three or more domain controllers
Network services and resources such as messaging, database, file and print, proxy server, firewall, Internet, intranet, remote access, and client computer management
Connectivity requirements such as connecting branch offices and individual users in remote locations to the corporate network and connecting corporate networks to the Internet
