Network Implementation Flashcards
Net+ N10-009
Subnetting
Dividing a network into smaller subnetworks to improve management and security.
Crosstalk
Effect caused by the unintentional and undesired transmission of a signal from one cable to another
What is VLSM (Variable Length Subnet Masking)?
Allows subnets of varying sizes within the same network.
Jitter
Time delay between when a signal is transmitted and when it’s received over a network connection
NetFlow
Collects IP traffic information and monitoring network flow.
What is trunking?
Technique used to carry multiple VLANs over a single network link using VLAN tagging.
What does STP (Spanning Tree Protocol) do?
Prevents network loops by creating a loop-free logical topology.
What is link aggregation?
Combines multiple physical network connections into one logical connection to increase bandwidth and provide redundancy.
What is port forwarding?
Directs external network traffic to a specific internal IP address and port.
What is IPSec (Internet Protocol Security) used for?
Secures IP communications through encryption and authentication.
What do WPA (Wi-Fi Protected Access) and WPA2 provide?
Provide security protocols to protect wireless networks from unauthorized access.
What is 802.1X used for?
Provides port-based network access control for securing network access.
What does ARP stand for and what does it do?
Address Resolution Protocol maps an IP address to a MAC address on a local network.
What is a DHCP lease?
Is the duration for which an IP address is assigned to a device before it must be renewed.
What is a DHCP scope?
Range of IP addresses that a DHCP server can assign to clients on a network.
What is VLAN tagging?
Adds a tag to Ethernet frames to identify which VLAN the frame belongs to
What is a VPN tunnel?
A secure, encrypted connection established between a client and a VPN server over a public network.
What is PAT in networking?
Maps multiple private IP addresses to a single public IP address with different port numbers.
What does MPLS stand for and what is its use?
Multiprotocol Label Switching is used to efficiently route data through a network based on labels rather than IP addresses.
What does RADIUS stand for and what is its function?
Remote Authentication Dial-In User Service is used for centralized authentication, authorization, and accounting for network access.
What is throughput?
Rate at which data is successfully transmitted over a network, measured in bits per second.
What does MTU stand for and what does it specify?
Maximum Transmission Unit specifies the largest size of a packet that can be transmitted over a network.
What does BGP stand for and what is its role?
Border Gateway Protocol is used to exchange routing information between different autonomous systems on the internet.
What is network latency?
Latency is the delay before a transfer of data begins following an instruction for its transfer.
