1. Define Load Balancing and Fault Tolerance.

Expert Solution

Answer:

Load balancing:

Load balancing is the process of distributing network traffic across multiple servers. This ensures no single server bears too much demand. By spreading the work evenly, load balancing improves application responsiveness. It also increases availability of applications and websites for users. Modern applications cannot run without load balancers. Over time, software load balancers have added additional capabilities including security and application.

Fault tolerance:

Fault Tolerance simply means a system’s ability to continue operating uninterrupted despite the failure of one or more of its components. This is true whether it is a computer system, a cloud cluster, a network, or something else. In other words, fault tolerance refers to how an operating system (OS) responds to and allows for software or hardware malfunctions and failures.

An OS’s ability to recover and tolerate faults without failing can be handled by hardware, software, or a combined solution leveraging load balancers(see more below). Some computer systems use multiple duplicate fault tolerant systems to handle faults gracefully. This is called a fault tolerant network.

The CAP theorem says a database cannot have all three of these features: partition (fault tolerance) and consistency and availability. We know that both MongoDB database system and Cassandra database system provide fault tolerance (partition). So how do they handle consistency and availability in their different ways? How does the MongoDB database system handle both consistency and availability in spite of what is stated by the CAP theorem? How does the Cassandra database system handle both consistency and availability in...

No-fault liability or no-fault insurance means: A. If the employee admits it is the fault of the employee for falling down at work, they receive a larger benefit from worker's compensation. B. None are correct. C. If an employer admit it is not the fault of the employer, they receive reduced rates. D. There are larger legal fees because no one admits they were wrong.
