A subnet of 255.255.248.0 can be represented by what CIDR notation?

A subnet mask of 255.255.248.0 is equivalent to a CIDR notation of /21. To determine the CIDR notation for a given subnet mask, count the number of consecutive 1 bits in the subnet mask. In this case, the subnet mask has 21 consecutive 1 bits, so the corresponding CIDR notation is /21. CIDR notation is commonly used in IP networking to specify the size of a subnet or network, and is expressed as a number of bits in the subnet mask. For example, a /24 CIDR notation indicates a subnet mask of 255.255.255.0, while a /16 CIDR notation indicates a subnet mask of 255.255.0.0.

What does the VLAN Trunk Protocol (VTP) do?

VLAN Trunk Protocol (VTP) is a Cisco proprietary protocol that allows switches to exchange VLAN information with each other. VTP is used to manage VLAN configurations in a switched network environment by maintaining a consistent database of VLAN information among all switches in the network. When VTP is enabled, switches can dynamically add, delete, and rename VLANs and propagate these changes to other switches in the network. VTP operates by designating one switch in the network as the VTP server, which is responsible for managing the VLAN database. The other switches in the network can be configured as VTP clients, which receive VLAN information from the server and synchronize their VLAN databases accordingly. VTP also supports the use of VTP transparent mode, in which a switch does not participate in VTP updates but can still forward VLAN traffic. One important thing to note is that VTP only works within a single administrative domain, meaning that it is limited to switches that are directly connected to each other. If switches are connected through a router or a Layer 3 boundary, VTP updates will not be propagated beyond that boundary.

When using RFID, what is an ARPT (Active Reader Passive Tag)?

ARPT (Active Reader Passive Tag) is an RFID system architecture in which an active RFID reader sends a radio signal to passive RFID tags. The passive tags are not powered and do not transmit any signals unless they receive a signal from the active reader. When the active reader sends a signal to the passive tag, the tag responds by modulating the signal and reflecting it back to the reader. The reader then reads the modulated signal and extracts the information encoded in the tag. In this architecture, the reader is active and the tags are passive.

An evil twin attack is a type of wireless network attack where an attacker creates a fake wireless access point (AP) that looks like a legitimate AP. The attacker can use this fake AP to intercept and manipulate network traffic, steal user credentials or sensitive information, or launch other attacks such as phishing or malware distribution.
