Which of the following is a design pattern?
- a)Factory (correct answer)
- b)List
- c)Queue
- d)All of these
Answer and explanation
Correct answer: (a) Factory
A design pattern is a reusable, named solution to a recurring design problem in a given context. Factory is a creational pattern: client code asks a factory (a method or object) for an object, and the factory decides which concrete class to create, so the client depends only on an interface and not on the concrete class. Other well-known patterns are Singleton and Builder (creational), Adapter and Facade (structural), and Observer and Strategy (behavioural).
Why the other options are wrong
- (b) List: a data structure (an ordered collection of elements), not a design pattern.
- (c) Queue: a data structure that holds elements for processing, usually first-in-first-out; it is not a design pattern.
- (d) All of these: List and Queue are not design patterns, so not all of the options are correct.
Tip: Patterns describe how to design (Factory, Singleton, Observer); List, Queue, Stack and Tree are data structures that store data.

Which is the standard protocol for network management features?
- a)SNMP (correct answer)
- b)SNA
- c)FTP
- d)SMTP
Answer and explanation
Correct answer: (a) SNMP
SNMP (Simple Network Management Protocol) is the standard Internet protocol for network management. A network management station (the manager) sends Get and Set requests to an agent running on each managed device, such as a router, switch, server or printer, to read or change values stored in the device's MIB (Management Information Base). Agents also send unsolicited trap messages to report events. SNMP runs over UDP: requests go to port 161 and traps to port 162.
Why the other options are wrong
- (b) SNA: Systems Network Architecture is IBM's proprietary networking architecture for mainframe-centred networks, not the standard Internet network-management protocol.
- (c) FTP: File Transfer Protocol moves files between hosts; it cannot query or configure device status.
- (d) SMTP: Simple Mail Transfer Protocol relays e-mail between mail servers.
Tip: Monitoring or managing network devices = SNMP (manager, agent, MIB; UDP 161/162).
