Broadcast address

Question 22: Which encryption method uses a pair of keys: one public and one private?

Symmetric-key encryption

Hash-based encryption

Asymmetric-key encryption

Stream cipher encryption

Question 23: What does a RAID system provide in terms of data management?

Faster network speeds

Dynamic IP addressing

Data redundancy and fault tolerance

Encryption of sensitive data

Question 24: What is a major difference between IPv4 and IPv6 addressing?

IPv4 addresses are longer than IPv6 addresses

IPv6 uses a 128-bit address, while IPv4 uses a 32-bit address

IPv4 can support more devices than IPv6

IPv6 addresses are encrypted, while IPv4 addresses are not

Question 25: What is the purpose of NAT (Network Address Translation)?

To resolve domain names to IP addresses

To allow devices with private IP addresses to communicate with public networks

To encrypt data for secure transmission

To filter network traffic based on predefined security rules

Question 26: What does APIPA (Automatic Private IP Addressing) do in the absence of a DHCP server?

It assigns a public IP address to devices on the network

It assigns a private IP address from a reserved range

It encrypts data for secure communication

It maps domain names to IP addresses

Question 27: What is the primary purpose of a router in a network?

To assign dynamic IP addresses

To filter data packets based on security rules

To route data packets between different networks

To amplify network signals

Question 28: What type of backup method copies all data regardless of changes?

Differential backup

Full backup

Incremental backup

Mirror backup

Question 29: What is an example of a physical layer device in the OSI model?

Router

Switch

Hub

Firewall

Question 30: What does a VLAN (Virtual Local Area Network) allow you to do?

Encrypt network traffic between devices

Segment a network into logical parts without physical separation

Automatically assign IP addresses

Amplify weak signals in a network

Question 31: Which protocol is responsible for email retrieval from a server?

SMTP

HTTP

FTP

IMAP

Question 32: Which security protocol is designed to make a wireless network as secure as a wired one?

WEP

WPA2

SSL

HTTPS

Question 33: What is the purpose of a patch panel in a network?

To terminate and manage network cables

To encrypt network traffic

To amplify network signals

To assign dynamic IP addresses

Question 34: What type of cable is RG-58, and what is it commonly used for?

Shielded cable used for electrical wiring

Question 35: Which type of wireless network allows two devices to communicate directly without an access point?

Infrastructure mode

Ad hoc mode

WPA2

CSMA/CA

Question 36: What is the purpose of a backup system in network management?

To encrypt data for secure transmission

To provide fault tolerance and data recovery in case of system failure

To assign dynamic IP addresses

To filter network traffic

Question 37: What does DNSSEC provide for DNS queries?

Encryption of DNS requests

Digital signatures to ensure the authenticity of DNS responses

Dynamic IP address assignment

Resolution of domain names to IP addresses

Question 38: What type of cable is used in a bus topology?

Twisted-pair

Coaxial cable

Fiber-optic cable

USB cable

Question 39: What is a key advantage of fiber-optic cables over copper cables in networking?

Lower cost

Resistance to electromagnetic interference

Simplicity of installation

Better support for legacy systems

Question 40: What is the purpose of an encryption protocol in network security?

To assign dynamic IP addresses

To ensure that data is only accessible to authorized users

To map domain names to IP addresses

To amplify weak signals in a network
