Port security is a feature that can be enabled on network switches for the purpose of enhancing network security by controlling which devices are allowed to connect to specific switch ports.

When port security is used on a switch which violation mode will cause an snmp trap to be sent and traffic to be dropped when the number of secure MAC address for a port is reached?
Port security is used on a switch and the number of secure MAC addresses for a port is reached, the violation mode that will typically cause an SNMP trap to be sent and traffic to be dropped is the "Shutdown" or "Protect" violation mode.
What switch port modes will allow a switch to successfully form a trunking link if the neighboring switch port is in dynamic desirable mode?
since the first desire of desirable mode is to trunk,so the switch port mode will be trunking since the first desire of desirable mode is to trunk,so the switch port mode will be trunking
What type of module a switch use it to modify the media type supported by a switch port?
SFP
What does the term port density represent for an Ethernet switch?

Which two statements describe the operation of an access layer ethernet switch choose two?
The source MAC address within a frame is used by the switch to associate a port with that MAC address. Frames are directed by the switch from one port to another based on the destination MAC address within the frame.
When port security is enabled a switch port uses the default violation mode of until specifically configured to use a different violation mode?
Yes, By default port security is disabled on a Cisco switch. If it is enabled the default violation mode is shutdown with a maximum MAC address count of 1. Even if port-security is enabled it will not place a port into the shutdown state until either MAC address sticky or a static MAC address is configured on the port.
What is the valid reason for a switch to deny port access to new devices when port security is enabled?
The denied MAC address are statically configured on the port
What is 'err-disabled' error. it is frequently blocking the port of your cisco switch?
This is caused by port security being enabled and having the violation setting set to shutdown. This is triggered when you have two many MAC addresses listed for the port of if a BPDU is sent to that port, depending on how port security is configured.
Is there a way to configure a cisco switch in order to avoid this kind of attack?
Yes, there should be, but it would vary depending on the security features of the switch port - google "switchport port-security" for examples. Once this is set, the switch won't forward packets to addresses outside of the specified range.
What step must be completed before port security can be enabled on an interface?
The violation mode must be configured.
RSTP is enabled in a switched network that is active and converged Which switch port type assumes a discarding state on non-root switches?
alternate port
What address does a switch use for implementing port security?
source mac address
Which address does a switch use for implementing port security?
The source MAC address
What is a valid reason for a switch to deny port access to new devices when port security is?
The denied MAC address are statically configured on the port
How would you disable a typical serial port on a motherboard?
The port can be enabled or disabled through the CMOS setup.
Which Cisco switch feature is used to limit the number of valid MAC addresses that a switch associates with a switchport?
port security
How much would a 4 port switch cost?
4 port switches can be purchased on Amazon for as little as £5.36. You can pay up to £195.86 if you wish for more advanced features and greater security.
