Which solution improves web response time by deploying multiple web servers and DNS servers?
- distributed databases
- load balancing
Explanation: Maintaining availability is the primary concern for companies working with big data. Some solutions to improve the availability include the following:
- Load Balancing – deploying multiple web servers and DNS servers to respond to requests simultaneously
- Distributed Databases – improving database access speed and demands
- Memcaching – offloading demand on database servers by keeping frequently requested data available in memory for fast access
- Sharding – partitioning a large relational database across multiple servers to improve search speed
