Mastering CCNA: Essential Tips and Sample Questions
Permalink   


Welcome to Computer Network Assignment Help, your go-to resource for mastering CCNA and excelling in your network administration studies. In this post, we delve into two master-level CCNA questions, each followed by a comprehensive solution prepared by our Professional CCNA Assignment Help. Whether you're studying for an exam or seeking to deepen your understanding, our solutions are designed to help you succeed.

Question 1: Subnetting Scenario

You have been assigned the network address 192.168.10.0/24 and need to create 6 subnets with equal numbers of hosts. Calculate the subnet mask and provide the network addresses for each subnet.

Solution:

To subnet the network address 192.168.10.0/24 into 6 subnets, follow these steps:

  1. Determine the required subnet bits:
  • We need 6 subnets, which requires 3 subnet bits (2^3 = 8 subnets, more than enough).
  1. Calculate the new subnet mask:
  • Original subnet mask is /24 (255.255.255.0).
  • Adding 3 subnet bits gives us a subnet mask of /27 (255.255.255.224).
  1. Find the subnet addresses:
  • Increment for each subnet: 32 (because 256 / 8 = 32).
  • Subnet addresses:
    • Subnet 1: 192.168.10.0/27
    • Subnet 2: 192.168.10.32/27
    • Subnet 3: 192.168.10.64/27
    • Subnet 4: 192.168.10.96/27
    • Subnet 5: 192.168.10.128/27
    • Subnet 6: 192.168.10.160/27

Question 2: OSPF Configuration

Configure OSPF routing protocol on a Cisco router using the following network addresses:

  • 192.168.1.0/24
  • 192.168.2.0/24
  • 192.168.3.0/24

Ensure proper OSPF area assignment and enable OSPF on all interfaces.

Solution:

To configure OSPF on a Cisco router with these network addresses:

  1. Access Router CLI and Enter Global Configuration Mode:

Router> enable Router# configure terminal Router(config)# router ospf 1

  1. Assign OSPF area and network addresses:

Router(config-router)# network 192.168.1.0 0.0.0.255 area 0 Router(config-router)# network 192.168.2.0 0.0.0.255 area 0 Router(config-router)# network 192.168.3.0 0.0.0.255 area 0

  1. Verify OSPF configuration:

Router(config-router)# end Router# show ip ospf neighbor

By following these steps, OSPF will be properly configured on your Cisco router with the specified network addresses.

We hope these solutions have clarified the concepts of subnetting and OSPF configuration. For more assistance with CCNA assignments or to access our sample assignments, visit Computer Network Assignment Help. Our expert team is dedicated to your success!
