#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 function of the Hypertext Transfer Protocol (HTTP) in web communication?
Retrieving and displaying web pages
ExplanationHTTP facilitates the transfer of web content between servers and clients.
#13
In networking, what is the purpose of Quality of Service (QoS)?
Prioritizing and managing network traffic
ExplanationQoS ensures certain network traffic receives priority to optimize performance.
#14
What is the purpose of the Simple Network Management Protocol (SNMP) in networking?
Monitoring and managing network devices
ExplanationSNMP enables centralized monitoring and management of network devices.
#15
Which layer of the OSI model is responsible for logical addressing and routing?
Network layer
ExplanationThe network layer handles logical addressing and routing of data packets.
#16
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.
#17
Which protocol is commonly used for secure communication over the Internet?
SSH
ExplanationSecure Shell (SSH) provides encrypted communication for secure access.
#18
Which protocol is responsible for assigning IP addresses dynamically to devices in a network?
DHCP
ExplanationDynamic Host Configuration Protocol (DHCP) assigns IP addresses automatically.
#19
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.
#20
Which protocol is commonly used for remote terminal access and control?
Telnet
ExplanationTelnet provides remote access to devices for terminal-based communication.
#21
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.
#22
Which protocol is commonly used for sending emails?
SMTP
ExplanationSimple Mail Transfer Protocol (SMTP) is used for sending emails.
#23
What is the role of a firewall in network security?
Detecting and blocking unauthorized access
ExplanationFirewalls monitor and control incoming and outgoing network traffic.
#24
What is the purpose of the File Transfer Protocol (FTP) in networking?
Transmitting files between devices
ExplanationFTP facilitates the transfer of files over a network.
#25
In networking, what does the acronym VLAN stand for?
Virtual Local Area Network
ExplanationVLAN segregates network devices into virtual networks for better organization.
