LWAPP
Light Weight Access Point Protocol is the name of a protocol that can control multiple Wi-Fi wireless access points at once.
DAI
Dynamic ARP Inspection
eDisocovery
eDiscovery is the term that refers to the process of evidence collection through digital forensics.
VLAN pooling
VLAN poolingis a feature that enables you to group multiple wireless controllerVLANsto form aVLAN pool. Configure aVLAN poolto load-balance sessions evenly across multipleVLANs
VLAN pooling provides a method by which administrators can deploy pools of multiple VLANs from which clients are assigned, thereby automatically segmenting large groups of clients into smaller subgroups, even when connected to the same SSID.
Notice of Legal Hold
A legal hold is a process that an organization uses to preserve all forms of relevant information when litigation is reasonably anticipated. If a legal hold notice has been given to the backup service, they will not destroy the old backup tapes until the hold is lifted.
______________________
A samplelitigation hold notice(also known as alegal hold noticeor document preservationnotice) from in-house counsel of a company facinglitigation, a government investigation, or an audit to employees about their obligation to preserve, and prevent the deletion or destruction of, relevant information and records.
LWAPP
LWAPP is a standard single point that allows quick and efficient management of multiple wireless devices at a time.
ATM cells
In the data link layer (layer 2) of the OSI model, the basic unit of transfer is called a frame. In an ATM network, these frames are called cells and are of a fixed (53 octets or bytes) length that allows for faster switching of the cells across the network.
At which of the following OSI layer does QoS operate?
Quality of Service (QoS) occurs at both Layer 2 and Layer 3 of the OSI Model.
A company is having a new T1 line installed. Which of the following does this connection MOST likely terminate to?
The telecom company usually terminates the circuits at the Main Distribution Facility (MDF).
Tim is a network administrator who is setting up three additional switches in his test lab. While configuring the switches, he is verifying the connectivity but finds that when he pings one of the switches using its IP address, he receives “Destination Unreachable”. What kind of issue is this?
Misconfigured Split Horizon
Explanation
Split horizon is a method of preventing a routing loop in a network. If it is misconfigured, the switches would be unable to communicate with each other. None of the other answers provided would prevent communication between the switches.
