Cisco IP Services & Configuration Competency (Intermediate Level)

Topics covered

• configure and verify the working of NTP, describe the need and use of NTP for synchronization of network devices, and describe how logging is important for networks
• configure Dynamic NAT (NAT Pooling) and Port Address Translation and verify the working configuration
• configure OSPFv2, describe unusual configuration details, set a router-id, and use commands to verify OSPF is operational
• configure VRRP and GLBP and use priority and preempt commands in HSRP
• describe DNS, configure a Cisco router to work as a DNS server, and describe how DHCP is required by clients using DNS
• describe dynamic routing protocol concepts such as types, metrics, and administrative distance, as well as how routers learn routes
• describe FHRPs and why you would use them and configure HSRP
• describe FTP and TFTP in the context of device management and use them to back up the IOS image
• describe how any action on a Cisco device is logged, how and where logs are stored and displayed on the router, and how to understand the log messages
• describe how DHCP manages and distributes IP information configured on it to clients, how the process occurs (DORA), and how to configure the DHCP server and a DHCP relay
• describe IP forwarding, the process of how frames move through multiple routers to the destination, and how routers build routing tables for that action to occur
• describe the basics of how OSPF works, the conditions of becoming OSPF neighbors, and what OSPF builds within the router to populate the routing table
• describe the need for QoS, terminology commonly used in configuring QoS, and what per-hop behaviors do
• describe the use of IPv4 static default and network routes, configure routers to use the routes, and describe why certain routing decisions are made
• describe the use of IPv6 static default and network routes, configure routers to use the routes, and describe why certain routing decisions are made
• describe the use of NAT with IPv4, configure static NAT, describe how static NAT works, and recognize the drawbacks of using static NAT
• describe what SNMP does, how to configure it, and the different versions
• describe why it's important to enable remote access using SSH instead of Telnet, elements required to ensure that remote access to devices is secured, and how to verify that the secured access works
• implement additional types of IPv4 static routing, configure host routes and floating static routes, and describe the importance of and how to test routes
• implement additional types of IPv6 static routing, configure host routes and floating static routes, and describe the importance of and how to test routes
