Homework Help: Questions and Answers: What is the first thing you should do after installing all relevant cabling and hardware in your new building?

A. Convert your PC from DHCP to a static IP address.
B. Run a speed test to ensure the advertised speeds are met.
C. Test all network sharing and printing functionality.
D. Change the default passwords on new network devices.

Answer:

First, let’s understand the question: It’s about to determine the best practices for network security and configuration after setting up hardware and cabling.  

Given Options: Step by Step Answering

a) Convert your PC from DHCP to a static IP address.

• This is typically done for specific devices like servers or printers that need fixed IP addresses for stability. However, this step is more about network configuration and isn’t the first thing that should be done across all devices.

b) Run a speed test to ensure the advertised speeds are met.

• While checking network performance is important, this comes later, after ensuring the network is secure and functioning correctly.

c) Test all network sharing and printing functionality.

• Before testing functionalities like sharing or printing, the first concern should be security. If devices are not secure, testing functionality could expose the network to risks.

d) Change the default passwords on new network devices.

• This is a critical step in securing your network. Default passwords on network devices (like routers and switches) are well-known and often targeted by attackers. Changing these immediately after installation helps secure the network before proceeding with other configurations or tests.
• This is the best practice and should be the first thing you do after installation.

Final Answer

Based on the above analysis, the correct answer is:

d) Change the default passwords on new network devices.

This is the most crucial first step because it immediately improves the security of your new network. It prevents potential unauthorized access that could occur if someone were to connect to your network and find devices with default credentials. Only after securing your devices should, you proceed with other tasks like configuring IP addresses, testing speeds, and setting up network functionality.
