MAC filtering is a method used to control access to a network by allowing only devices with specific MAC addresses to connect. This directly prevents unauthorized devices from gaining network access. Although MAC addresses can be spoofed, this method is a straightforward way to prevent unauthorized access at the network level. Anti-malware, translation gateways, and VPNs do not specifically prevent unauthorized access to the internal network in the manner described by the question.
Terrible question but A, mac filtering is the only thing that makes sense, nothing else prevents network access.
Will the VPN prevent me from connecting my laptop to a network cable? The answer is A
Mac addresses can be spoofed, that is not safe.
A VPN creates a secure and encrypted connection over a public network (such as the internet) and allows authorized users to access the internal network securely. By using strong encryption and authentication mechanisms, a VPN ensures that only authenticated and authorized users can establish a connection to the internal network, while also protecting the data transmitted over the network.
the question is asking how to PREVENT access to an internal network, not what is a secure way to access it. To PREVENT access you MAC filter, to securely access it you need VPN!!! answer is A!!!
I will go with D. Question states "prevent unauthorized access to the internal network" so preventing connections from any other place but the internal network what can be achieved by a VPN. NAC is for securing the internal network so to me, it does not apply.
I went with D as MAC addresses can be spoofed or flooded thus making VPN a more secure option.
The question just wants to know how to stop people from accessing the Internal Network and VPN won't do that.
MAC addresses can be spoofed, option A is not valid. Anti-malware protects against malware but doesn't provide any sort of authentication, option B is invalid. Translation gateway is used by NAT to share the same Public IP address, it has nothing to do with access control. VPN encrypts data making it unreadable if spoofed plus provides various authentication methods including a username and password, radius server, digital certificates, active directory, and MFA.
I will go with MAC Filter.
VPN only
The answer D.VPN
VPN is the answer
VPN would be correct
MAC filtering is a method used to control access to a network based on the MAC addresses of devices. While it can be a useful additional layer of security, it is not typically considered the best solution for preventing unauthorized access to an internal network. I would go with VPN
A VPN creates a secure, encrypted tunnel between the user’s device and the network. This can effectively prevent unauthorized access to the internal network.
It would need to specify remote access. VPN's cannot be used locally
