Routing Operations & Processes

These flashcards cover key terms and concepts related to routing operations and processes in computer networks.

Router

A network device that forwards data packets between computer networks.

Routing Table

A database in a router that stores information about the routes to various network destinations.

Gateway

A network point that acts as an entrance to another network, often used in routing.

Routing Protocol

A set of rules that determine how data packets are forwarded and routed between devices in a network.

Longest Match Algorithm

The method used to select the most specific entry in a routing table that corresponds to the destination address.

Distance Vector

A routing protocol type that determines the best path based on the least number of hops to the destination.

Link State

A routing protocol that uses comprehensive information about the state of links to determine the best path.

Static Route

A manually configured path in a routing table that does not change automatically.

Dynamic Route

A path learned through routing protocols that can be updated as the network topology changes.

Default Route
\n

A path used when the router does not have an explicit route to the destination network.

Decapsulation

The process by which a router removes the header from a data packet to read its destination address.

Encapsulation

The wrapping of data in a protocol header before transmission.

NVRAM

Non-volatile Random Access Memory, used to store the router's startup configuration.

Routing Process

The procedure through which routers determine the best path for forwarding packets.

Physical Connectivity

The physical aspects of a router, including ports and I/O interfaces, that define communication methods.

Logical Connectivity

The configuration of a router that defines how it connects with other devices logically, using routing tables.

RIP

Routing Information Protocol, a type of distance vector routing protocol.

OSPF

Open Shortest Path First, a link-state routing protocol that bases routing decisions on various metrics.

EIGRP

Enhanced Interior Gateway Routing Protocol, a Cisco proprietary routing protocol that combines aspects of distance vector and link-state protocols.

MAC Address

A hardware address that uniquely identifies each device on a network.

Subnetting

Dividing a network into smaller, manageable sub-networks to improve efficiency and security.

Frames

Data packets used in Layer 2 (Data Link layer) of the OSI model for communication.

True or False: A router's primary function is to forward data packets between different computer networks.

True

True or False: A Routing Table stores information about the physical MAC addresses of devices on the local segment.

False (It stores routes to network destinations.)

True or False: The Longest Match Algorithm is used to find the least specific entry in a routing table.

False (It finds the most specific entry.)

True or False: Distance Vector protocols determine the best path based on the highest number of hops.

False (They use the least number of hops.)

True or False: Static routes automatically update when network topology changes.

False (They are manually configured and do not change automatically.)

True or False: A Default Route is used when a router has a specific, explicit route to the destination network.

False (It is used when no explicit route exists.)

True or False: Decapsulation is the process of adding a header to a data packet before transmission.

False (That is encapsulation; decapsulation is removing headers.)

True or False: NVRAM stores the router's running configuration.

False (It stores the startup configuration.)

True or False: Physical Connectivity describes how a router connects logically using routing tables.

False (That describes Logical Connectivity.)

True or False: RIP is a link-state routing protocol.

False (RIP is a distance vector routing protocol.)

True or False: OSPF is a Cisco proprietary routing protocol.

False (OSPF is an open standard protocol.)

True or False: EIGRP combines aspects of distance vector and link-state protocols.

True

True or False: A MAC address is a software address assigned to a device by the operating system.

False (A MAC address is a hardware address.)

True or False: Subnetting divides a single network into larger, less manageable segments.

False (It divides a network into smaller, more manageable sub-networks.)

True or False: Frames are data packets used at Layer 3 (Network layer) of the OSI model.

False (Frames are used at Layer 2, the Data Link Layer.)
