Which layer in a three-tier software platform architecture is responsible for presenting data to the user?
Business logic layer
Presentation layer
Data layer
Network layer
The presentation layer handles the user interface and displays data to users. The business logic layer processes data, and the data layer stores it.
Which of the following components is primarily responsible for distributing network traffic across multiple servers to ensure reliability and availability?
DNS server
Load balancer
Database server
Firewall
A load balancer distributes incoming traffic across servers to improve availability and reliability. Firewalls filter traffic but do not distribute load.
In a layered software platform architecture, which component is tasked with persistent storage of application data?
API gateway
Data layer
Web server
Application server
The data layer contains databases or storage services for persistent data. Application and web servers handle logic and client requests.
What term describes the software that enables communication and data management for distributed applications by connecting different components?
Firmware
Middleware
Operating system
Kernel
Middleware sits between applications to facilitate communication and data exchange. Firmware is low-level device software and the kernel manages hardware.
Which security component is designed to monitor and control incoming and outgoing network traffic based on predetermined security rules?
Firewall
Load balancer
Compiler
Router
A firewall enforces security policies by filtering network traffic. Routers direct packets, and load balancers distribute traffic without enforcing security rules.
Which method is commonly used for integrating applications using HTTP-based communication in modern platforms?
Local file system
SFTP transfers
REST API
Manual file exchange
REST APIs use standard HTTP methods for integrating applications. SFTP and manual exchanges are file-based and not as dynamic.
Which integration pattern employs a broker to facilitate asynchronous message-based communication between services?
Batch processing
Publish - subscribe
Point-to-point synchronous
Remote procedure call
The publish - subscribe pattern uses a message broker to decouple producers and consumers asynchronously. RPC is synchronous and point-to-point.
Why is API versioning considered a best practice in platform integration?
To replace logging mechanisms
To encrypt data in transit
To maintain backward compatibility for clients
To improve network bandwidth
API versioning allows older clients to continue using a stable interface while newer versions evolve. It does not directly impact bandwidth or encryption.
What does horizontal scaling of a platform involve?
Refactoring code for performance
Adding more instances of servers to distribute load
Increasing database cache size
Upgrading server CPU and memory
Horizontal scaling adds more server instances to handle increased load. Upgrading hardware is vertical scaling, and code refactoring or caching are optimizations.
Which benefit is primarily achieved by implementing a caching mechanism in a platform?
Direct database schema migration
Automatic resource provisioning
Reduced data retrieval latency
Enforcement of security policies
Caching stores frequently accessed data close to the application, minimizing latency. It does not handle security enforcement or resource provisioning.
Which practice helps prevent SQL injection attacks in a software platform?
Using parameterized queries or prepared statements
Disabling input validation
Storing credentials in plain text
Exposing database internals via API
Parameterized queries separate code from data, preventing malicious injections. Disabling validation or exposing internals increases risk.
What is the primary purpose of TLS (Transport Layer Security) in platforms?
Managing user identities
Balancing server loads
Encrypting data at rest
Securing data in transit by encryption
TLS encrypts network communications to protect data in transit. It does not handle load balancing, at-rest encryption, or identity management.
Which protocol is widely used for delegated authorization, allowing third-party applications to access user resources with consent?
SMTP
FTP
OAuth 2.0
SNMP
OAuth 2.0 issues tokens for secure, delegated access to user resources. FTP transfers files, SMTP sends email, and SNMP handles network management.
What approach allows infrastructure resources to be managed and provisioned through code, improving repeatability in platform management?
Manual server configuration
Single-node deployment
Waterfall methodology
Infrastructure as Code
Infrastructure as Code uses declarative templates or scripts to automate resource provisioning. Manual methods lack repeatability and are error prone.
Which monitoring metric is most directly used to evaluate how much processing capacity a server is using?
User session count
Disk I/O latency
Network packet loss rate
CPU utilization percentage
CPU utilization shows the percentage of processing power in use. Disk I/O latency measures storage performance, and packet loss relates to network quality.
Which resilience pattern should be implemented to prevent cascading failures in microservices by halting requests to an unresponsive service?
Retries with exponential backoff
Bulkhead isolation
Load balancing
Circuit breaker pattern
The circuit breaker pattern stops requests to a failing service to prevent overload and cascading failures. Bulkheads isolate resources but do not stop calls.
In the CAP theorem for distributed data stores, which two guarantees does the "CP" category prioritize?
Performance and Scalability
Consistency and Partition tolerance
Availability and Partition tolerance
Consistency and Availability
The CP category ensures data consistency and partition tolerance at the expense of availability. It cannot guarantee all three simultaneously.
To anticipate usage spikes and adjust resources before they occur, which auto-scaling strategy should a platform employ?
Rolling updates
Predictive auto-scaling based on forecasted metrics
Reactive scaling on threshold breach
Manual scaling triggered by admins
Predictive auto-scaling uses historical and forecasted data to provision resources proactively. Reactive scaling acts only after thresholds are exceeded.
Which deployment strategy involves running two identical production environments and switching traffic to the new one to minimize downtime?
A/B testing
Canary release
Blue - green deployment
Rolling update
Blue - green deployment keeps two live environments and shifts traffic instantly to the new one. Canary releases gradually roll out to a small subset.
In a multi-tenant platform requiring strong data isolation, what is a suitable architectural approach to separate tenant data?
Store all data in memory
Use a single database user for all tenants
Separate database schema per tenant
Single shared schema with no tenant IDs
Using separate schemas per tenant isolates data logically while sharing infrastructure. A shared schema without tenant identifiers risks data leakage.
