The printed paper will come out creased.

Which characteristics of a cable modem distinguish it from other modems?

They are always on. They use cable TV lines.

Which characteristics of a switch can be advantageous to network deployment?

They improve network performance by regulating the flow of traffic. They increase network performance by reducing collisions.

Virtual Network Interface Card (NIC)

An entity that is created in software that allows a Virtual Machine (VM) to access the Ethernet network. It is configured just like its physical counterpart with an IP address, default gateway but exists entirely within the software. It is bridged with a physical NIC which places its frames on the wired network with a MAC address that is unique to the virtual NIC.

You want to perform passive reconnaissance in your organization and test out the security controls. You want to perform a passive DNS assessment and want to know the details of the organization's DNS servers. Which method would help you achieve your goal?

Execute a WHOIS query. WHOIS is a passive method where the target is not involved and the information is retrieved without connecting with the target. When you run a WHOIS query, the target domain is not interacted with. If the domain information is publicly available, then you will be able to retrieve the information including the DNS server names.
