Networking and IP Addressing Quiz

A company is assigned the network 192.168.50.0/24. The network administrator needs to create 8 equal subnets. What will be the new subnet mask and the number of usable hosts per subnet?

• /26, 62 hosts

• /27, 30 hosts

• /28, 14 hosts

• /29, 6 hosts

You are given the IP address 172.16.10.130/25. Which of the following is the correct network ID and broadcast address?

• Network: 172.16.10.128, Broadcast: 172.16.10.255

• Network: 172.16.10.0, Broadcast: 172.16.10.127

• Network: 172.16.10.128, Broadcast: 172.16.10.191

• Network: 172.16.10.0, Broadcast: 172.16.10.255

Which of the following best describes the primary purpose of a VLAN?

• To encrypt data between two devices

• To logically separate networks without additional physical switches

• To increase wireless bandwidth

• To replace the need for routing protocols

Which of the following characteristics belong to UDP? (Select TWO)

• Connectionless communication

• Reliable delivery with acknowledgments

• Low overhead and faster performance

• Three-way handshake before data transfer

Arrange the following DHCP steps in the correct order: DHCP Offer, DHCP Ack, DHCP Discover, DHCP Request

• 3 → 1 → 4 → 2

• 1 → 3 → 2 → 4

• 3 → 4 → 1 → 2

• 2 → 3 → 1 → 4

Which of the following scenarios would be the best use of a DHCP reservation?

• Assigning IP addresses to mobile phones that change networks often

• Ensuring a network printer always receives the same IP address

• Preventing a group of addresses from being used by DHCP

• Allowing devices to self-assign IPs when no DHCP is available

A technician notices a workstation has an IP address of 169.254.100.5. What does this most likely indicate?

• The device is using SLAAC for IPv6 addressing

• The device is configured with a static IP

• The device could not contact a DHCP server

• The device has duplicate IP detection enabled

Which of the following statements are true about SLAAC? (Select TWO)

• It requires a DHCPv6 server to function

• It generates IPv6 addresses using EUI-64

• It supports Duplicate Address Detection (DAD)

• It provides DNS server information automatically

Which of the following are advantages of using DHCPv6 compared to SLAAC?

• Centralized control of address assignments

• Simpler configuration with no need for servers

• Ability to assign additional configuration such as DNS

• Works only with IPv4 networks

A user reports they cannot access the internet. You run ipconfig and see the workstation has an IP address of 169.254.55.22 with no default gateway listed. What is the most likely issue?

• The DNS server is unreachable

• The DHCP server did not assign an IP address

• The workstation has a duplicate IP conflict

• The NIC is disabled
