Information Technology FAQs
How do I design a secure network architecture diagram for an IT assignment?
Incorporate core components such as firewalls, VLAN segregation, DMZ zones, intrusion detection systems (IDS), and redundant core routers following defense-in-depth principles.
What is the difference between symmetric and asymmetric cryptography?
Symmetric encryption uses a single shared secret key for both encryption and decryption. Asymmetric encryption uses a public/private key pair for secure key exchange and digital signatures.
How do I write a comprehensive IT disaster recovery and business continuity plan?
Define Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO), establish backup strategies, outline failover procedures, and schedule periodic disaster recovery testing.
What are the core phases of the Systems Development Life Cycle (SDLC)?
The SDLC phases include Planning, Requirement Analysis, System Design, Implementation/Coding, Testing, Deployment, and Ongoing Maintenance.
How do I normalize a relational database to Third Normal Form (3NF)?
Eliminate repeating groups (1NF), remove partial functional dependencies (2NF), and remove transitive dependencies where non-key attributes depend on other non-key attributes (3NF).
What is cloud computing service models (IaaS, PaaS, SaaS) comparison?
IaaS provides raw infrastructure (servers/storage), PaaS provides a managed development environment, and SaaS delivers complete software applications via the web.
How do I troubleshoot common TCP/IP networking issues?
Use diagnostic commands like ping, traceroute, netstat, nslookup, and Wireshark packet capture to isolate routing errors, DNS failures, or packet loss.
What is IT service management (ITSM) and the ITIL framework?
ITSM aligns IT services with business needs using ITIL best practices covering incident management, problem management, change enablement, and service desk operations.
How do I write an information security policy document?
Outline acceptable use guidelines, password complexity rules, access control mechanisms, data classification standards, and incident reporting protocols.
Can I get help writing Python scripts or Linux shell automation scripts?
Yes. Support is available for scripting file backups, automating system administration tasks, parsing log files, and managing permissions.
