What is the default configuration of the PVLAN Edge feature on a Cisco switch?
All active ports are defined as protected.
All ports are defined as protected.
No ports are defined as protected.
EtherChannel groups are defined as protected ports.
Under which circumstance is it safe to connect to an open wireless network?

The device has been updated with the latest virus protection software.
The connection is followed by a VPN connection to a trusted network.
The user does not plan on accessing the corporate network when attached to the open wireless network.

CCNA Security Chapter 6 V1.2
How does a switch interface that uses sticky port security handle MAC addresses?
They are configured dynamically and are saved in the running configuration.
They are configured dynamically and are not saved in the running configuration.
They are configured manually and are not saved in the running configuration.
The addresses are configured manually and are saved in the running configuration.
Refer to the exhibit. The Fa0/2 interface on switch S1 has been configured with the switchport port-security mac-address 0023.189d.6456 command and a workstation has been connected. What could be the reason that the Fa0/2 interface is shutdown?
The connection between S1 and PC1 is via a crossover cable.
The Fa0/24 interface of S1 is configured with the same MAC address as the Fa0/2 interface.
S1 has been configured with a switchport port-security aging command.
The MAC address of PC1 that connects to the Fa0/2 interface is not the configured MAC address.
Which action best describes a MAC address spoofing attack?
bombarding a switch with fake source MAC addresses
flooding the LAN with excessive traffic
forcing the election of a rogue root bridge
altering the MAC address of an attacking host to match that of a legitimate host
Which mitigation technique can help prevent MAC table overflow attacks?
Which type of frame is spoofed in STP manipulation attacks?
Which attack allows the attacker to see all frames on a broadcast network by causing a switch to flood all incoming traffic?
MAC table overflow
802.1q double tagging
Where is the port security configuration most effective in a multi-layer switched network environment?
on core layer switches
on perimeter layer switches
on access layer switches
on distribution layer switches
What happens when the MAC address notification feature is enabled on a switch?
A port violation occurs when a MAC address outside of the range of allowed addresses transmits traffic over a secure port.
An STP multicast notification packet is forwarded to all switches any time a change in the network topology is detected.
An SNMP trap is sent to the network management system whenever a new MAC address is added to or an old address is deleted from the forwarding tables.
An SDEE alert is generated, and the switch resets the interface when an invalid MAC address is detected.
Which statement describes a MAC address table overflow attack?
Frames flood the LAN, creating excessive traffic and degrading network performance.
A software tool floods a switch with frames containing randomly generated source and destination MAC and IP addresses
An attacker alters the MAC address in a frame to match the address of a target host.
The attacking host broadcasts STP configuration and topology change BPDUs to force spanning-tree recalculations.
If a switch is configured with the storm-control command and the action shutdown and action trap parameters, which two actions does the switch take when a storm occurs on a port? (Choose two.)
An SNMP log message is sent.
he port is placed in a blocking state.

The port is disabled.
When configuring a switch port for port security, what is the default violation mode?
Refer to the exhibit. Which two statements are correct regarding the configuration on switch S1? (Choose two.)

Port Fa0/6 storm control for multicasts and broadcasts will be activated if traffic exceeds 2,000,000 packets per second.
Port Fa0/6 storm control for multicasts will be activated if traffic exceeds 2,000,000 packets per second.
Port Fa0/5 storm control for broadcasts and multicasts will be activated if traffic exceeds 80.1 percent of 2,000,000 packets per second.
Port Fa0/5 storm control for broadcasts will be activated if traffic exceeds 80.1 percent of the total bandwidth.
