This post is about answer for CCNA Security Chapter 6 Test. The questions displayed in this post are based on CCNAS v1.1. All the answers has been confirmed to be 100% correct. With this solution, hopefully it will be a good reference for all of us.
As a recommended practice for Layer 2 security, how should VLAN 1 be treated?
All access ports should be assigned to VLAN 1.
All trunk ports should be assigned to VLAN 1.
VLAN 1 should be used for management traffic.
VLAN 1 should not be used.
With IP voice systems on data networks, which two types of attacks target VoIP specifically? (Choose two.)
Which option best describes a MAC address spoofing attack?
An attacker gains access to another host and masquerades as the rightful user of that device.
An attacker alters the MAC address of his host to match another known MAC address of a target host.
An attacker alters the MAC address of the switch to gain access to the network device from a rogue host device.
An attacker floods the MAC address table of a switch so that the switch can no longer filter network access based on MAC addresses.
Which attack relies on the default automatic trunking configuration on most Cisco switches?
LAN storm attack
VLAN hopping attack
STP manipulation attack
MAC address spoofing attack
Which two measures are recommended to mitigate VLAN hopping attacks? (Choose two.)
Use a dedicated native VLAN for all trunk ports.
Place all unused ports in a separate guest VLAN.
Disable trunk negotiation on all ports connecting to workstations.
Enable DTP on all trunk ports.
Ensure that the native VLAN is used for management traffic.
Which three are SAN transport technologies? (Choose three.)
Refer to the exhibit. What action will the switch take when the maximum number of secure MAC addresses has reached the allowed limit on the Fa0/2 port?
Packets with unknown source addresses are dropped, but notification of the dropped packets is sent.
The VLAN that Fa0/2 is on is set to error-disabled and all traffic on the VLAN is stopped.
The interface immediately becomes error-disabled and the port LED is turned off.
Packets with unknown source addresses are dropped without notification.
Which software tool can a hacker use to flood the MAC address table of a switch?
kiwi syslog server
Which two methods are used to mitigate VLAN attacks? (Choose two.)
enabling port security on all trunk ports
using a dummy VLAN for the native VLAN
implementing BPDU guard on all access ports
disabling DTP autonegotiation on all trunk ports
using ISL instead of 802.1q encapsulation on all trunk interfaces
Which three switch security commands are required to enable port security on a port so that it will dynamically learn a single MAC address and disable the port if a host with any other MAC address is connected? (Choose three.)
switchport mode access
switchport mode trunk
switchport port-security maximum 2
switchport port-security mac-address sticky
switchport port-security mac-address mac-address
What is an example of a trusted path in an operating system?
hash message authentication
Ctrl-Alt-Delete key sequence
Why are traditional network security perimeters not suitable for the latest consumer-based network endpoint devices?
These devices are not managed by the corporate IT department.
These devices are more varied in type and are portable.
These devices connect to the corporate network through public wireless networks.
These devices pose no risk to security as they are not directly connected to the corporate network.
Which Cisco IronPort appliance would an organization install to manage and monitor security policy settings and audit information?
Which Cisco IronPort appliance would an organization install to protect against malware?
What is the goal of the Cisco NAC framework and the Cisco NAC appliance?
to ensure that only hosts that are authenticated and have had their security posture examined and approved are permitted onto the network
to monitor data from the company to the ISP in order to build a real-time database of current spam threats from both internal and external sources
to provide anti-malware scanning at the network perimeter for both authenticated and non-authenticated devices
to provide protection against a wide variety of web-based threats, including adware, phishing attacks, Trojan horses, and worms
When the Cisco NAC appliance evaluates an incoming connection from a remote device against the defined network policies, what feature is being used?
authentication and authorization
quarantining of noncompliant systems
remediation of noncompliant systems
Which command is used to configure the PVLAN Edge feature?
switchport port-security violation protect
Which statement is true about a characteristic of the PVLAN Edge feature on a Cisco switch?
All data traffic that passes between protected ports must be forwarded through a Layer 2 device.
All data traffic that passes between protected ports must be forwarded through a Layer 3 device.
Only broadcast traffic is forwarded between protected ports.
Only unicast traffic is forwarded between protected ports.
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 connection utilizes the 802.11n standard.
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.
