Which of the following is a primary component of information systems architecture responsible for storing and managing data?
Database Management System
Central Processing Unit
Operating System
Network Switch
A Database Management System is specifically designed to store, retrieve, and manage data. The CPU processes instructions, the operating system manages hardware resources, and a network switch directs network traffic.
Which hardware component is the main processor handling instructions and computations?
Central Processing Unit (CPU)
Random Access Memory (RAM)
Hard Drive
Firewall Appliance
The CPU is the primary processor that executes instructions and performs computations. RAM is volatile memory storage, a hard drive stores data long-term, and a firewall appliance manages network security.
Which type of software controls and allocates hardware resources on a computer?
Operating System
Spreadsheet Application
Network Switch Firmware
Antivirus Scanner
An operating system manages and allocates hardware resources, such as CPU and memory. A spreadsheet application is end-user software, switch firmware handles network device operations, and antivirus software scans for malware.
Which network device directs data packets between different networks based on IP addresses?
Router
Network Switch
Modem
Hub
A router examines IP addresses to forward data packets between networks. A switch directs packets within a network segment, a modem connects to an ISP, and a hub broadcasts to all ports.
Which phase of the system development life cycle focuses on gathering user needs and requirements?
Requirements Analysis
System Design
Implementation
Testing
Requirements Analysis is the phase where user needs and system requirements are collected and documented. Design translates requirements into specifications, implementation builds the system, and testing verifies functionality.
What is the primary goal of data normalization in relational database design?
Reduce data redundancy
Improve network latency
Increase system complexity
Boost transaction throughput
Normalization organizes data into tables to minimize redundancy and avoid update anomalies. While it can affect throughput or complexity, reducing redundancy is its main objective.
Which security measure ensures that data remains confidential during transmission over a network?
Encryption
Firewall
Load Balancing
Backup
Encryption encodes data so that only authorized parties can read it, ensuring confidentiality. Firewalls control access, load balancers distribute traffic, and backups store copies of data.
In the OSI model, which layer is responsible for logical addressing and routing of packets?
Network Layer
Transport Layer
Data Link Layer
Presentation Layer
The Network layer handles logical addressing (e.g., IP addresses) and routes packets across networks. The Transport layer manages end-to-end connections, the Data Link layer handles local frames, and the Presentation layer formats data.
Which database feature supports the ACID property of consistency by ensuring transactions leave the database in a valid state?
Commit and rollback mechanisms
Data replication
Query caching
Transparent encryption
Commit and rollback ensure that transactions fully complete or fully revert, maintaining consistency. Replication and caching address availability and performance, while encryption secures data.
Which software development methodology emphasizes iterative development and frequent stakeholder feedback?
Agile
Waterfall
V-Model
Spiral
Agile methodology uses short iterations with continuous feedback to adapt to change. Waterfall is sequential, V-Model is a verification-focused waterfall variant, and Spiral centers on risk analysis.
What is the primary function of a network firewall within an organizational system?
Filter incoming and outgoing traffic
Store backup data
Balance network load
Encrypt data at rest
A firewall filters and controls network traffic based on security rules to protect systems. Backup devices store data, load balancers distribute traffic, and encryption secures stored data.
In a relational database, what uniquely identifies each record in a table?
Primary Key
Foreign Key
Index
View
A primary key is a unique identifier for records in a table, ensuring each row is distinct. A foreign key links tables, an index speeds up queries, and a view is a virtual table.
Which component of information systems architecture is primarily responsible for user interactions and presentation of information?
User Interface
Middleware
Data Warehouse
DNS Server
The user interface layer handles user interactions and displays information. Middleware connects components, data warehouses store aggregated data, and DNS servers resolve domain names.
Which transport protocol provides connection-oriented, reliable data delivery?
TCP
UDP
IP
HTTP
TCP establishes a connection and ensures reliable, ordered delivery of packets. UDP is connectionless, IP handles routing, and HTTP is an application-layer protocol over TCP.
During which phase of the system development life cycle are deployed systems monitored and issues resolved post-launch?
Maintenance
Implementation
Testing
Deployment
Maintenance involves monitoring, updating, and fixing issues in a live system. Implementation builds the system, testing verifies it, and deployment releases it to users.
Which type of database is best suited for handling large volumes of unstructured data with a flexible schema?
NoSQL document database
Relational database
In-memory database
Hierarchical database
NoSQL document databases support flexible, schema-less data models for unstructured data and scale horizontally. Relational databases require fixed schemas, in-memory databases focus on speed, and hierarchical databases use tree structures.
In a multi-tier system architecture, which tier is responsible for processing business logic and rules?
Application tier
Presentation tier
Data tier
Network tier
The application tier (or business logic tier) implements rules and processes data between presentation and data tiers. Presentation tier handles UI, data tier manages storage, and network tier concerns connectivity.
A company needs both user authentication and non-repudiation for critical transactions. Which security mechanism best provides both?
Digital signatures
Password authentication
SSL/TLS encryption
CAPTCHA verification
Digital signatures verify identity and ensure messages cannot be denied later, offering both authentication and non-repudiation. Passwords authenticate but lack non-repudiation, TLS encrypts data but doesn't prevent denial, and CAPTCHAs are for bot prevention.
When designing a disaster recovery strategy, which replication method minimizes potential data loss by synchronously updating both primary and secondary sites?
Synchronous replication
Asynchronous replication
Cold-site backup
Tape archival
Synchronous replication writes data to both primary and secondary sites simultaneously, ensuring minimal data loss. Asynchronous replication can lag, cold-sites require manual recovery, and tape archives are not real-time.
Which UML diagram is most appropriate for modeling the states and transitions of a system component under various conditions?
State Machine Diagram
Class Diagram
Use Case Diagram
Sequence Diagram
State Machine Diagrams model the states of a component and transitions triggered by events. Class diagrams show structure, use case diagrams depict interactions, and sequence diagrams illustrate message flows.
