SUN CERTIFIED NETWORK ADMINISTRATOR FOR SOLARIS 9 OPERATING ENVIRONMENT OBJECTIVES

CONFIGURE THE NETWORK INTERFACE LAYER:

• Describe the advantages of using a layered network model and describe the functions of the network interface, internet, transport, and application layers of the TCP/IP model.
• Describe basic peer to peer communication and related TCP/IP protocols.
• Describe the features and functions of LAN components, including network topologies, media, and network devices.
• Describe Ethernet concepts and statistics, including the major Ethernet elements and the CSMA/CD access method.
• Describe the components of an Ethernet frame.
• Explain how to use snoop, netstat, and ndd on an Ethernet interface.
• Describe the function and management of the ARP and RARP.

CONFIGURE THE NETWORK (INTERNET AND TRANSPORT LAYERS):

• Describe the purpose, features, and functionality of internet layer protocols, IP datagram, IP address types, subnetting and VLSM, and interface configuration files as used in an IP configuration.
• Explain how to configure and unconfigure logical interfaces in IP.
• Explain the purpose, benefits, and limitations of multipathing, and explain how to configure multipathing using configuration files and command-line.
• Describe the purpose and limitations of trunking, and explain how the four supported trunking policies impact how trunking is implemented.
• Explain the purpose and usage of routing types (direct and indirect), routing schemes (static and dynamic), and routing protocol types (autonomous systems, interior routing protocols, and exterior routing protocols).
• Given a routing table example, describe table entries, identify the routing table search order, and associate a network name to a network number.
• Explain how to configure static and dynamic routing, and the configuration of routing at boot time.
• Describe the operation of CIDR.
• Given a routing scenario problem, troubleshoot the router configuration and/or network names and select a resolution.
• Identify purpose, features, and functionalities for different types of unicast, multicast, and anycast addressing, and autoconfiguration as they relate to IPv6 addressing.
• Explain how to configure Ipv6 on a router and non router, and troubleshoot configuration and interface problems.
• Explain how to configure IPv6 over IPv4 tunnels and IPv6 multipathing.
• Distinguish among protocol characteristics of the transport layer, and explain the fundamentals of TCP and UDP.

CONFIGURE AND MANAGE NETWORK APPLICATIONS (APPLICATION LAYER):

• Explain the purpose of DNS in a network environment.
• Explain how to configure a primary and secondary DNS server and a DNS client.
• Given DNS server output for a problem scenario, identify strategies to resolve the problem.
• Describe the purpose and features of DHCP client and server functions.
• Describe how to configure a DHCP server and use associated utilities.
• Given DHCP debug output, deduce deduce resolution strategies.
• Explain how to configure and manage a DHCP client to request either a dynamic host name or use its own host name.
• Explain how to configure a DHCP server to support jumpstart clients.
• Describe the purpose, features, and functions of NTP, and define NTP terms.
• Explain how to configure an NTP server and an NTP client.
• Explain how to view logs and use snoop to troubleshoot an NTP problem.
