CCNA Practice Certification Exam # 2- CCNA Exploration: Accessing the WAN (Version 4.0)

1. Refer to the exhibit. The exhibit shows simplified protocol data units from different OSI model layers. Which three statements are true about the PDUs and the encapsulation

process? (Choose three.)

PDU #1 is a frame.

PDU #2 is an application layer PDU

PDU #3 is a segment.

PDU #4 is a transport layer PDU.

The order in which these PDUs are created during the encapsulation process is 3, 4, 1, 2.

The order in which these PDUs are created during the encapsulation process is 2, 1, 4, 3.

2. Which three application layer protocols use TCP? (Choose three.)

SMTP

FTP

SNMP

HTTP

TFTP

DHCP

3. Which two application layer protocols use the UDP protocol? (Choose two.)

Telnet

SNMP

SMTP

SQL

TFTP

4. What are two functions that occur at the Internet layer of the TCP/IP model? (Choose two.)

establishment of logical connections between source and destination hosts

end-to-end flow control

determination of best paths through the network

definition of the procedures used to interface with the network hardware

packet switching

Layer 5 and Layer 6 OSI model functions

5. Refer to the exhibit. All ports on switch A are in the sales VLAN and all ports on switch B are in the accounting VLAN. How many broadcast domains and how many collision

domains exist in the exhibited network? (Choose two.)

3 collision domains

3 broadcast domains

5 broadcast domains

9 collision domains

10 collision domains

13 collision domains

6. A high-end Catalyst switch that supports both ISL and 802.1Q is to be connected by a link that will carry all VLAN traffic to a Catalyst 2960 LAN switch. What two commands

are required to configure an interface on the high-end Catalyst switch to carry traffic from all VLANs to the Catalyst 2960 switch? (Choose two.)

Switch(config-if)# vlan all

Switch(config-if)# switchport access vlan 30

Switch(config-if)# switchport access vlan all

Switch(config-if)# switchport mode trunk

Switch(config-if)# switchport trunk encapsulation dot1q

Switch(config-if)# switchport trunk encapsulation isl

7. Refer to the exhibit. Based on the exhibited configuration and output, what would be the result of this command:

Sw1# telnet 192.168.1.10
