CCNA RS 200 125 Exam blueprint
1.OSI
2.TCP three-way handshake four times wave
3.IP VLSM division CIDR subnet summary
4. Device Management Router Password Cracking Switch Password Cracking IOS Refilling (Routers and Switches)
5. Switch Technology How the Switch Works (MAC Learning and Forwarding)
VLAN technology (logically isolating multiple broadcast domains in a Layer 2 network)
Trunk (dot1q commonly used and ISL) dot1q encapsulation all vlan id isl only standard vlan 1-1005
Vlan configuration of VTP synchronous switch server client transparent mode pruning (vtp pruing)
Port-security whitelist If the mac address is changed, the penalty mechanism is triggered. The port is shut down.
Prevent mac flood attacks (continuously change your own source MAC address) (switch mac address entries continue to learn errors, you need to flood when you go to the correct address)
EtherChannel (etherchannel) provides redundant load balancing (working simultaneously) guarantees high availability
Pagp (Cisco protocol max. 8) lacp (16 simultaneous work 8 8 as backup) two protocols
STP spanning tree to solve some problems caused by redundant loopback
6. Routing function
Static route manual configuration Declare which network segment to go to which interface
RIP routing protocol (the first dynamic protocol) Periodic 30s forwarding routing table Learning each other's network segments that are not self-connected
Maximum 16 hops (16 hops unreachable) Small network Compare the distance with hops If the hops are the same, load balancing
EIGRP Interior Gateway Protocol VLSM CIDR has a neighbor relationship. Check if the neighbor has a problem. 120
Neighbor table - routing update (put in the topology table dual algorithm to calculate the best path and then put it into its own routing table)
Followed by incremental update / trigger update
OSPF Link State Routing Protocol SPF Algorithm Calculates the COST value to calculate
Hello neighbor relationship to pass DB message first Confirm master and slavery
LSR requests LSU
Routing updates are not entries that are passed with LSA
Multi-regional division 0-65535 Region 0 is the backbone in the middle (similar to Lotus)
Single area does not use area 0
7.ACL
Distinguish between IN and OUT
Standard source IP address match 1-99 1300-1999
Expansion source IP port number protocol to match 100-199 2000-2699
8.NAT
Internal - public network ip
Static (one-to-one server) external network can access internal server Dynamic and pat do not support external to internal
Dynamic address pool
PAT multiple internal IP mapping to a public network A public network has more than 60,000 port numbers
It is about ccna rs blueprint above. If you want to pass ccna exam that had better to review ccna rs 200 125 dumps. It will help you pass exam quickly that take ccnp rs eaxm.
