The Solaris Network Administration exam is the last exam netadmins must take to gain the Sun Certified Network Administrator credential -- and with the Solaris 8 upgrade, many netadmins must take the exam to renew their certifications. This authoritative guide is the first book to cover the Sun Certified Network Administrator for Solaris 8 exam. Written by the technical lead for the Sun Microsystems team that wrote the Solaris 8 Network Certification exam, it focuses on the most challenging aspects of network and TCP/IP administration -- and offers all the review questions, tips, and resources netadmins need to successfully prepare for the exam. The book presents modular coverage of sixteen networking-related topics in depth, building from basic to more complex topics. Long-time Sun trainer and support professional Ricky Bushnell simplifies difficult topics like DNS, sub-netting, routing, and IPv6 though clear, easy-to-follow examples -- highlighting the key points you need to review to pass the exam. The book contains extensive review questions and self-test exam questions, and is supported with additional questions and updates on the more

Complete coverage of the exam objectives--by the technical lead for the certification exam development team! The only exam prep book endorsed by Sun Educational Services, this study guide focuses on the basic knowledge and skills network administrators need to solve real-world problems. Network expert Rick Bushnell presents a comprehensive review of the essential concepts covered in the Network Administrator exam. He assumes you have a working knowledge of Solaris 7 or 8, but that you need to supplement your understanding of Solaris Network Administration, TCP/IP, and related protocols. Each of the official exam objectives is reviewed to provide an understanding of the underlying technologies and to enhance your knowledge of network administration and TCP/IP. The fundamental approach is to reinforce your understanding of key network administration skills and then test your understanding with review questions that will prepare you for the real exam. Key topics covered include: Network Models Ethernet InterfaceARP and RARP The IP ProtocolRouting over TCP/IPThe Transport Layer Protocols (TCP/UDP)The Client/Server ModelDHCPManaging Networks Domain Name Service (DNS)The Network Time Protocol This indispensable guide covers the network protocol stack from top to bottom. You won't find a more authoritative, useful resource anywhere. Endorsed as a study guide for the Sun Certified Network Administrator for Solaris 8 Operating Environment by Sun Educational more
