Question

b) Proxy Server Configuration
c) DNS Resolution Problems
d) MAC Address Filtering

Answer 1

The inability for office2 and itadmin to access the internet while another computer can could be due to network firewall issues, proxy server configuration errors, DNS resolution problems, or MAC address filtering.

Step-by-step explanation:

When troubleshooting network connectivity issues where one computer can access the internet but others cannot, evaluating certain configurations and settings is crucial. The possibilities listed, such as network firewall issues, proxy server configuration, DNS resolution problems, and MAC address filtering, each can affect connectivity in different ways.

• Network firewall issues may prevent specific devices from reaching the internet if policies are set to block their traffic.
• Proxy server configuration is typically used to manage internet access and filtering; incorrect settings could restrict access for certain users or machines.
• DNS resolution problems can occur if a device is unable to resolve domain names into IP addresses, which is essential for accessing websites.
• MAC address filtering is used for network security, allowing only approved devices onto the network; any device not on the whitelist will be unable to connect.

Determining the root of the issue requires a systematic approach to checking each of these aspects in the context of the network's configuration.
