Chapter 1: Internetworking Flashcards
What is an Internetwork?
When routers connect two or more networks together and use logical addressing (IP or IPv6).
How do switches segment a network?
Switches create separate collision domains but a single broadcast domain.
How do routers segment a network?
Routers provide a separate broadcast domain for each interface.
What OSI layer provides a user interface?
The Application Layer
Which OSI Layer presents data, and handles processing such as encryption?
The Presentation Layer
Which OSI layer keeps different applications’ data separate?
The Session Layer
Which OSI layer provides reliable or unreliable delivery. Performs error correction before retransmit?
The Transport Layer
Which OSI Layer provides logical addressing which routers use for path determination?
The Network Layer
Which OSI Layer combines packets into bytes and bytes into frames.
Provides access to media using MAC address. Performs error detection not correction?
The Data Link Layer
Which OSI layer moves bits between devices. Specifies voltage, wire speed, and pin-out cables?
The Physical Layer
Which OSI layer has File, print, message, database, and application services?
The Application Layer
Data encryption, compression, and translation services is performed on which OSI layer?
The Presentation Layer
Dialog control - simplex, half duplex, and full duplex is handled by which OSI Layer?
The Session Layer
End-to-end connection, segments and reassembles data into a data stream by which OSI layer?
The Transport Layer
Routing is the function of which OSI layer?
The Network Layer
Framing is the function of which OSI layer?
The Data Link Layer
Physical topology is the function of which OSI layer?
The Physical Layer
Which OSI Layer establishes sessions and tears down virtual circuits?
The Transport Layer
Which OSI Layer maintains Flow control?
The Transport Layer
What are the characteristics of connection oriented service?
A virtual circuit
Sequencing
Acknowledgements
Flow control
What are the three types of flow control?
Buffering, windowing, and congestion avoidance
What is a routed protocol?
Protocols used to support data traffic. i.e IP and IPv6
What are routing protocols?
Protocols that send update packets. i.e RIP, RIPv2, EIGRP, and OSPF
Will routers forward broadcast or multicast packets?
No
Can routers provide Layer 2 bridging functions?
Yes
Can routers simultaneously route through the same interface?
Yes
Do Layer 3 devices provide connections between virtual LANS?
Yes
Can routers provide quality of service (QOS) for specific types of network traffic?
Yes
Which OSI layer provides the physical transmission of data and handles error notification, network topology, and flow control?
The Data Link Layer
Is Layer 2 switching considered hardware based?
Yes
Which layer machine uses filter tables?
Layer 2 (switches and bridges)
Hubs are at what Layer?
Layer 1
Switches and bridges are at what Layer?
Layer 2
Routers are at what Layer?
Layer 3
