1. What are link aggregation and multipath bonding? How are they similar? How are they different?
2. Describe the “building block” approach to high availability networks. If you can’t build a network from scratch this way, how can high availability be fit into an existing network?
3. Describe what VRRP or CARP do for a network.
4. What are the problems that can be encountered when attempting to back up a high-availability database? What kinds of solutions exist?
5. What does a enterprise directory server do? Why are they important for the configuration and management of services?
Explanation / Answer
In order to increase throughput beyond what a single connection could sustain and to provide redundancy in case one of the links should fail various multiple network connections are combined in parallel.This is called as link aggregation.examples of aggregation at layer1 (physical layer) include power line. and wireless.Multipath bonding allows a host to be redundantly connected to the network by two independent paths.There are other bonding methods,but as you want high availiablity ip multipathing is your best bet.Unlike the floating virtual IP method of multipathing redundancy,bonding interfaces with new virtual interface.unlike redhat to configure bonding we need to associate two physical interfaces with virtual bonded interface bond within the standard network configuration files.The difference between linkaggregation and mutipath bonding is given as follows:
The similarity between Link aggregation also called as trunking and multipath bonding is that they are similar in functions improve network performance and availability.
