_________________ is a cisco proprietary protocol that gathers information about neighboring (attached) Cisco devices on local and wide area network segments.
cisco discovery protocol
The ______ timer defines how often a device transmits packets
cdp
The ____________ command shows information about neighboring cisco devices
What command does so in more detail?
show cdp nighbors
show cdp neighbors detail
_____________ is a Layer 2 MikroTik proprietary protoco9l that is used within a system running RouterOS to gather information on devices that are directly connected to the interface
MNDP
(Mikrotok Neighbor Discovery Protocol)
____________ are Layer 2 devices used to define collision domains with independent bandwidth on each port.
Switches
What are the three functions of a switch?
Learining addresses (making mac tables)
forwarding and filtering packets based on mac table
Network Loop avoidance by using STP
Switches use _____________ to automatically monitor links between all bridges (switches) in a network to prevent network loops
What kind of data does it use to communicate with?
Spanning Tree Protocol
BPDUs (Bridge Protocol Data Units)
Which of the five stp port states is this?
____________ does not forward, accept network traffic, or learn and MAC addresses. Port recieves (but does not send) BPDUs.
Blocking
Which of the five stp port states is this?
_____________ Sends and receives BPDUs, but does not learn MAC addresses, or forward/
process traffic. Calculating a loop-free topology occurs when ______________
Listening
Which of the five stp port states is this?
__________ Learns MAC addresses and populates the MAT to prevent flooding, but does
not forward traffic.
learning
Which of the five stp port states is this?
____________ Processes and forwards traffic, while actively learning MAC addresses from
incoming traffic; considered normal switch operation.
Forwarding
Which of the five stp port states is this?
____________ Administratively shutdown; does not participate in STP or forward frames.
Disabled
_________________ is based on the 802.1w standard, developed to make STP
convergence quicker. _______ works by using Hello messages.
RSTP
Which of the three rstp port states is this?
___________ No user data is sent over the port. This is comparable to the blocking,
listening, and disabled states of the original 802.1d STP specification.
Discarding
Which of the three rstp port states is this?
_____________ MAT population.
Learning
Which of the three rstp port states is this?
____________ Processes and forwards traffic, while actively learning MAC addresses from
incoming traffic; considered normal switch operation.
Forwarding
______________ was developed as a means to speed
up the transition process. __________ forces switch ports to immediately enter the forwarding
state, bypassing the STP listening and learning states.
PortFast
Portfast should only be used on ports that have a single host connected T/F?
T
How can I tell through an interface if a router is modular or not?
if there is an ethernet0/1 then that router is modular if its just ethernet1 it non-modular
A ____________ is a virtual interface that uses a parent physical interface
sub-interface
A ____________ is a virtual interface used to encapsulate data within a separate protocol
tunnel
A __________ virtual interface configured on a router, is used for maintenance/management functions.
Loopback
The _____ interface provides an alternative method of filtering traffic
null
_______________ method by which an interface is configured without a dedicated IP address.
IP unnumbered
