#1
Which of the following is a transport layer protocol?
TCP
ExplanationTransmission Control Protocol for reliable data delivery.
#2
What does the acronym TCP/IP stand for in networking?
Transmission Control Protocol/Internet Protocol
ExplanationTCP/IP is the fundamental protocol suite for internet communication.
#3
Which of the following is a characteristic of the Border Gateway Protocol (BGP)?
Routing protocol for the Internet
ExplanationBGP manages routing between different autonomous systems on the internet.
#4
Which of the following is a key feature of the Transmission Control Protocol (TCP)?
Flow control and error-checking
ExplanationTCP ensures reliable data delivery through flow control and error-checking mechanisms.
#5
Which of the following is a protocol commonly used for secure communication over the web?
HTTPS
ExplanationHTTPS encrypts data transmitted over the web to ensure security.
#6
What is the primary function of the Internet Protocol (IP) in networking?
Addressing and routing data packets
ExplanationIP handles addressing and routing for data transmission.
#7
Which of the following is a characteristic of User Datagram Protocol (UDP)?
Connectionless
ExplanationUDP is connectionless, offering low-latency but less reliability.
#8
In networking, what is the purpose of the Domain Name System (DNS)?
Resolving domain names to IP addresses
ExplanationDNS translates human-readable domain names into IP addresses.
#9
What is the key difference between a hub and a switch in networking?
Switches broadcast data to all connected devices, while hubs selectively transmit data.
ExplanationSwitches intelligently route data to intended recipients, unlike hubs.
#10
What is the purpose of a MAC address in networking?
Identifying a device in a local network
ExplanationMAC address uniquely identifies devices on a local network.
#11
What does NAT stand for in networking?
Network Address Translation
ExplanationNAT translates private IP addresses to public IP addresses.
#12
What is the role of a subnet mask in networking?
Identifying the network portion of an IP address
ExplanationSubnet mask helps in dividing IP addresses into network and host portions.
#13
Which protocol is commonly used for secure communication over the Internet?
SSH
ExplanationSecure Shell (SSH) provides encrypted communication for secure access.
#14
Which protocol is responsible for assigning IP addresses dynamically to devices in a network?
DHCP
ExplanationDynamic Host Configuration Protocol (DHCP) assigns IP addresses automatically.
#15
What is the purpose of the OSI model in networking?
To standardize network protocols and communication
ExplanationOSI model offers a standard framework for understanding network communication.
#16
Which protocol is commonly used for remote terminal access and control?
Telnet
ExplanationTelnet provides remote access to devices for terminal-based communication.
#17
What is the primary purpose of the Address Resolution Protocol (ARP) in networking?
Converting MAC addresses to IP addresses
ExplanationARP resolves IP addresses to MAC addresses on a local network.
