CCNA Security Chapter 6 - 2014

1. 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.
2. With IP voice systems on data networks, which two types of attacks target VoIP specifically? (Choose two.)
		CoWPAtty
		Kismet
	>>	SPIT
		virus
	>>	vishing
3. 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.
4. 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
5. 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.
6. Which three are SAN transport technologies? (Choose three.)
	>>	Fibre Channel
		SATA
	>>	iSCSI
		IP PBX
	>>	FCIP
		IDE
7. 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.
8. Which software tool can a hacker use to flood the MAC address table of a switch?
	>>	macof
		Cisco CCP
		kiwi syslog server
		protocol analyzer
9. 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
10. 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
		switchport port-security maximum 2
	>>	switchport port-security mac-address sticky
		switchport port-security mac-address mac-address
11.What is an example of a trusted path in an operating system?
		digital certificate
		digital signature
		hash message authentication
	>>	Ctrl-Alt-Delete key sequence
12. 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.
13. Which Cisco IronPort appliance would an organization install to manage and monitor security policy settings and audit information?
		C-Series
	>>	M-Series
		S-Series
		SenderBase-Series
14. Which Cisco IronPort appliance would an organization install to protect against malware?
		C-Series
		M-Series
	>>	S-Series
		SenderBase-Series
15. 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
16. 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
	>>	posture assessment
		quarantining of noncompliant systems
		remediation of noncompliant systems
17. Which command is used to configure the PVLAN Edge feature?
		switchport block
		switchport nonnegotiate
	>>	switchport protected
		switchport port-security violation protect
18. 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.
19. 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.
20. 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.
