Study Notes
Network Fundamentals
- A converged network uses one common infrastructure to carry voice, data, and video signals.
OSPF Protocol
- Hello packets are used by a router to discover neighbor routers and establish neighbor adjacency.
- In a single-area OSPF network, all routers are configured to belong to the same area.
Private IP Addresses and NAT
- Three advantages of using private IP addresses and NAT are:
- Conserves IPv4 addresses
- Improves network security by hiding internal IPv4 addresses
- Reduces the need for readdressing when changing ISPs
Cloud Computing
- Three benefits of cloud computing are:
- On-demand self-service for access to computing resources
- Rapid elasticity to quickly scale resources up or down
- Measured service to only pay for used resources
