Cloud & Network Security MCQs

Computer Networks

• A computer network is a collection of interconnected devices that can communicate and share resources with one another.

Types of Networks

• PAN (Personal Area Network): Smallest network type, usually confined to a few meters, designed for personal devices.
• LAN (Local Area Network): Limited to a small geographic area, such as a single building or campus, allowing for high-speed connections.
• MAN (Metropolitan Area Network): Spans a city or a large campus, larger than a LAN but smaller than a WAN.
• WAN (Wide Area Network): Covers a broad area, often a country or continent, connecting multiple LANs.

Network Topologies

• Bus Topology: All devices connected to a single central cable (the bus), leading to easier installation but potential drawbacks with cable failures.
• Star Topology: All devices connect to a central hub or switch, offering better fault tolerance but higher dependency on the central device.
• Mesh Topology: Each device is connected to every other device, providing high redundancy but requiring more cabling.

OSI Model

• A framework used to understand and implement network communications in seven layers: Application, Presentation, Session, Transport, Network, Data Link, and Physical.

IP Addresses

• A unique numerical label assigned to each device on a network, used for identification and communication within networks.

Subnet Mask

• A subnet mask is crucial for defining which portion of an IP address represents the network and which part represents the host.

Types of IP Addresses

• Two main types of IP addresses:
  • Static IP Address: Fixed address that does not change.
  • Dynamic IP Address: Assigned by a DHCP server and may change over time.

Email Protocol

• SMTP (Simple Mail Transfer Protocol): Protocol specifically used for sending emails, differentiating it from file transfer (FTP), domain name services (DNS), or web page transfers (HTTP).

Router Functions

• A router connects different networks, directing data packets between them, establishing paths to enable communication across diverse networks.

Wireless Connectivity

• Access Point: A device that provides wireless network connectivity, allowing devices to connect to a wired network.

Mesh Topology Truth Value

• In a mesh topology, it is true that every device connects to every other device, offering minimal downtime and robust communication.
