How does a distributed cache enhance the scalability of a web application?
- Decreases Cache Hit Rate
- Improves Session Management
- Increases Network Latency
- Reduces Database Load
A distributed cache reduces the load on the database by storing frequently accessed data, reducing the need to query the database, and thereby enhancing the scalability of a web application.
What is a potential downside of using round-robin load balancing in a heterogeneous server environment?
- Improved Resource Utilization
- Increased Latency
- Limited Fault Tolerance
- Uneven Distribution of Load
A potential downside of round-robin load balancing in a heterogeneous server environment is the uneven distribution of load, as servers may have different capacities or capabilities, leading to suboptimal performance.
How can containerization aid in scaling web applications?
- Enhanced Portability
- Improved Isolation
- Increased Hardware Utilization
- Reduced Microservices
Containerization aids in scaling web applications by providing enhanced portability, allowing applications to run consistently across different environments, facilitating easier scaling and deployment.
Load balancing is critical in a _________ architecture to distribute traffic evenly across servers.
- client-server
- microservices
- monolithic
- peer-to-peer
Load balancing is critical in a monolithic architecture to distribute traffic evenly across servers.
_________ scaling involves adding more resources to the existing servers.
- Diagonal
- Horizontal
- Parallel
- Vertical
Horizontal scaling involves adding more resources to the existing servers.
A _________ balancer distributes network or application traffic across a number of servers.
- Firewall
- Load
- Proxy
- Router
A Load balancer distributes network or application traffic across a number of servers.
In cloud environments, _________ scaling refers to the automated process of adding or removing resources as needed.
- Elastic
- Horizontal
- Static
- Vertical
In cloud environments, Horizontal scaling refers to the automated process of adding or removing resources as needed, also known as scaling out or in.
_________ is a strategy where new instances of the application are launched in different geographic locations to handle traffic.
- Caching
- Geographic Redundancy
- Replication
- Sharding
Geographic Redundancy is a strategy where new instances of the application are launched in different geographic locations to handle traffic and improve availability.
A web application experiences uneven load distribution despite using a load balancer. What could be the reason?
- Database Bottleneck
- Improper Load Balancer Configuration
- Inefficient Frontend Code
- Network Latency
Uneven load distribution may occur due to improper load balancer configuration, where it fails to distribute incoming requests evenly among the server instances.
A company is deciding between horizontal and vertical scaling. What factors should they consider in their decision?
- Cost, Scalability, and Maintenance
- Current Server Hardware Limitations
- Flexibility and Ease of Management
- Performance and Resource Utilization
The decision between horizontal and vertical scaling should consider factors such as cost, scalability needs, maintenance complexity, performance, resource utilization, flexibility, and ease of management.
