SAM QUIZ

Which of the following best describes the purpose of the network protocols?

• To provide physical connections between devices

• To ensure standardized communication between devices

• To enhance the speed of data transmission

• To encrypt data for security purposes

When subnetting a network, which of the following is NOT a reason to create subnets?

• To improve network performance

• To isolate network segments for security

• To simplify IP address management

• To increase the number of available IP addresses

Which of the following scenarios would require a network administrator to troubleshoot a connectivity

issue?

  resources

• All users can access the internet without issues

• A new device is added to the network without any configuration

• Class A

• Class B

• Class C

• Class D

Which of the following statements about CIDR (Classless Inter-Domain Routing) is true?

• It allows for more efficient use of IP addresses

• It is limited to Class A, B, and C networks only

• It requires a fixed subnet mask

• It is primarily used for IPv6 addressing

In a scenario where a device cannot connect to a network, which of the following services would you first check to ensure it has a valid IP address?

• DNS

• DHCP

• WINS

• SMB

If a network administrator is tasked with improving file sharing efficiency across different operating systems, which protocol would be most appropriate to implement?

• NFS

• FTP

• HTTP

• SMB

How does the use of DHCP enhance network security compared to static IP addressing?

• It makes it easier to track device locations

• It reduces the risk of IP address conflicts

• It prevents unauthorized access to the network

• It allows for easier implementation of firewalls

When troubleshooting a network file sharing issue, which of the following steps should be prioritized?

• Verify user permissions and access rights

• Change the network cable

• Reboot the DHCP server

In a hybrid network environment, how can DNS and DHCP work together to optimize network performance?

• By allowing DHCP to assign static IP addresses

• By enabling DNS to cache DHCP lease information

• By ensuring that DNS records are updated automatically with

  DHCP

• By allowing WINS to manage DNS queries
