CCENT Practice Certification Exam # 1 - CCNA Exploration: Accessing the WAN (Version 4.0)

14. Refer to the exhibit. Switch1 has only the following commands added to a default Cisco 2960 configuration:
enable secret cisco
line vty 0 4
password Kn0ckkn-cK
login
interface vlan 1
ip address 10.0.1.8 255.255.255.0
no shutdown
Assume that routing between networks is functioning properly and that Switch2 has been properly configured for remote access. What would the result be if the telnet 10.0.2.2 command is issued from Switch1 privileged mode?

	The following prompt would appear: User Access Verification Password:
	Switch2 would return a destination unreachable message to Switch1.
	Router1 would return a destination unreachable message to Switch1.
	The packet would be dropped.

15. What caused the following error message to appear?
01:11:12: %PM-4-ERR_DISABLE: psecure-violation error detected on Fa0/8, putting Fa0/8 in err-disable state
01:11:12: %PORT_SECURITY-2-PSECURE_VIOLATION: Security violation occurred, caused by MAC address 0011.a0d4.12a0 on port FastEthernet0/8.
01:11:13: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/8, changed state to down
01:11:14: %LINK-3-UPDOWN: Interface FastEthernet0/8, changed state to down

	Another switch was connected to this switch port with the wrong cable.
	An unauthorized user tried to telnet to the switch through switch port Fa0/8.
	NAT was enabled on a router, and a private IP address arrived on switch port Fa0/8.
	A host with an invalid IP address was connected to a switch port that was previously unused.
	Port security was enabled on the switch port, and an unauthorized connection was made on switch port Fa0/8.

16. When configuring a switch to use SSH for virtual terminal connections, what is the purpose of the crypto key generate rsa command?

	show SSH connected hosts
	disconnect SSH connected hosts
	create a public and private key pair
	show active SSH ports on the switch
	access the SSH database configuration

17. Which three statements are true about full-duplex operation on an Ethernet network? (Choose three.)

	There are no collisions in full-duplex mode.
	A dedicated switch port is required for each node.
	Hub ports are preconfigured for full-duplex mode.
	The host network card must detect the availability of the media before transmitting.
	The host network card and the switch port must both be in full-duplex mode.

18. Refer to the exhibit. If all the switches have a default configuration, how many broadcast domains are in the network?

	1
	2
	3
	4
	5
	14

19.

20. Refer to the exhibit. The devices have been configured with static IP addresses as shown. All hosts can communicate with each other but none of the hosts can communicate with the server. What is the cause of this problem?

	The IP address that is assigned to the server is in an incorrect subnet.
	The IP address that is assigned to the server is a broadcast address.
	The IP address that is assigned to the server is a network address.
	The switch to which the server is connected has not been assigned an IP address.
	The RouterB LAN interface is incorrectly addressed in the RouterA LAN subnet.

21. A network host has the IP address 10.250.206.55/20. How many more network devices can be added to this same subnetwork?

	253
	509
	1021
	2045
	4093

22. Which type of Network Address Translation allows a host on a public network consistent access to a specified private inside host?

	port-based NAT
	static NAT
	dynamic NAT
	NAT overload
