Advanced Network Tech Flashcards
(29 cards)
What is the main function of a router?
To forward packets to the best path toward their destination based on routing tables.
Name three ways a routing table can be populated.
Directly connected routes, Static routes, Dynamic routes.
What are two examples of dynamic routing protocols?
RIP, OSPF.
What are the three IPv4 address conservation techniques?
Private addresses, CIDR, VLSM.
What are the three methods for IPv4 and IPv6 coexistence?
Dual Stack, Tunneling, Translation (NAT64).
What is the major advantage of IPv6 over IPv4?
Much larger address space (2^128 addresses).
What notation is used to shorten IPv6 addresses?
Omitting leading zeros and using ‘::’ to compress consecutive zeros.
What does CIDR notation represent?
It specifies how many bits are used for the network portion of an IP address.
What is the main goal of segmentation in networking?
Boost performance and security by dividing a network into smaller collision domains.
What defines a collision domain?
Where data packets can collide and interfere with each other on the network.
Which device isolates collision domains?
Switches and routers.
What defines a broadcast domain?
All devices that receive broadcast frames at Layer 2.
What device breaks up broadcast domains?
Routers.
What are the three types of switching methods?
Circuit switching, Packet switching, Cell switching.
What technology uses cells instead of packets?
ATM (Asynchronous Transfer Mode).
Name an advantage of packet switching over circuit switching.
More efficient use of network resources and better scalability.
What is the speed range of Frame Relay?
56 kbps to 1.544 Mbps.
What is the 5-4-3 Rule in Ethernet?
5 segments, 4 repeaters, and only 3 populated with devices.
What is a MAC address composed of?
Organizationally Unique Identifier (OUI) and Device ID.
What is the purpose of Auto-MDIX?
Automatically detects cable type (straight-through or crossover) and configures accordingly.
What cabling standard is used for LANs?
Ethernet IEEE 802.3.
What is the difference between singlemode and multimode fiber?
Singlemode uses a laser and longer distances; Multimode uses LEDs and shorter distances.
What is a VPN used for?
Creating secure, encrypted tunnels over public networks.
What is the Demarcation Point?
The physical point where the customer’s network ends and the provider’s begins.
