IBM SWE 4.7 - Production Deployment Components

What are the common components required for deployment in a production environment?

• Web server, application server, database, load balancer, monitoring tools, security measures.

• Virtual machine, file server, DNS server

• Backup server, email server, proxy server

• Content delivery network, caching server, firewall

What is the primary purpose of a firewall in a production environment?

• To enhance network speed and performance.

• To provide a backup for data storage.

• To monitor employee internet usage.

• To protect the network from unauthorized access and threats.

How does a load balancer function in a web tier?

• A load balancer functions by redirecting all traffic to a single server.

• A load balancer is used to increase the size of a single server.

• A load balancer functions by distributing incoming traffic across multiple servers to optimize resource use, enhance performance, and ensure reliability.

• A load balancer only stores data for future requests.

What distinguishes a web server from an application server?

• A web server and an application server are the same and serve identical functions.

• A web server serves static content, while an application server provides business logic and dynamic content.

• A web server is used for database management, while an application server handles file storage.

• A web server processes business logic, while an application server serves static content.

What is the role of the presentation tier in an n-tier architecture?

• The presentation tier manages the user interface and user interactions in an n-tier architecture.

• The presentation tier processes business logic and application rules.

• The presentation tier is responsible for server-side operations and data processing.

• The presentation tier handles database management and data storage.

How does a proxy server differ from an application load balancer?

• A proxy server forwards requests and responses, whereas an application load balancer distributes traffic among servers.

• A proxy server encrypts data, whereas an application load balancer does not.

• A proxy server caches content, while an application load balancer monitors server health.

• A proxy server balances traffic, while an application load balancer forwards requests.

Why is it important to have multiple web servers behind a load balancer?

• It simplifies the network architecture by eliminating redundancy.

• It reduces server costs by using a single server.

• It allows for easier maintenance by having all traffic on one server.

• It ensures high availability, redundancy, and improved performance.

What security benefits does a firewall provide in a production setup?

• Firewalls eliminate the need for antivirus software.

• Firewalls are used to speed up network traffic.

• Firewalls provide protection against unauthorized access, malware, and network attacks, ensuring secure communication in a production setup.

• Firewalls only block spam emails.

Can you explain the concept of n-tier architecture?

• N-tier architecture eliminates the need for a database layer.

• N-tier architecture is a single-layer model for small applications.

• N-tier architecture is a model that divides an application into multiple layers, such as presentation, application, and data layers, to enhance scalability and maintainability.

• N-tier architecture only applies to web applications and not desktop software.

What types of servers are typically found in a production environment?

• Web servers, application servers, database servers, file servers, proxy servers

• mail servers

• DNS servers

• game servers
