CNA Practice Certification Exam # 1 - CCNA Exploration: Accessing the WAN
(Version 4.0)
1. What are three examples of TCP/IP application layer protocols? (Choose three.)
a terminal emulation protocol that supports remote console connections
with various network devices
a protocol created by IBM that makes it easier for mainframes to connect to remote
offices
a protocol responsible for transporting electronic mail on TCP/IP networks
and the Internet
a protocol that controls the rate at which data is sent to another computer
a protocol that exchanges network management information between a
network device and a management console
a protocol that conducts a test of the path through which a packet travels from
source to destination
2. 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.
3. What are two characteristics of TCP? (Choose two.)
data transport reliability
best path determination
establishing, maintaining, and terminating virtual circuits
encapsulation of packets in a data frame with source and destination MAC
addresses
best-effort datagram delivery
4. Refer to the exhibit. What type of Layer 2 encapsulation will be used for connection D
on the basis of this configuration on a newly installed router:
,RtrA(config)# interface serial0/0/0
RtrA(config-if)# ip address 128.107.0.2 255.255.255.252
RtrA(config-if)# no shutdown
Ethernet
Frame Relay
HDLC
PPP
5. Which three factors contribute to congestion on an Ethernet LAN? (Choose three.)
improper placement of enterprise level servers
addition of hosts to a physical segment
replacement of hubs with workgroup switches
increasing use of bandwidth intensive network applications
creation of new collision domains without first adding network hosts
migration to full-duplex Ethernet within the LAN
6. A Catalyst switch must be in which VTP mode in order to delete or add VLANs to a
management domain?
client
server
domain
transparent
designated
7. What creates a loop-free path through a switch network?
hold-down timers
poison reverse
Spanning Tree Protocol
Time to Live
Split Horizon Protocol
Routing Information Protocol
, 8. Refer to the exhibit. All ports on switch fl-1 are in the Production VLAN and all ports
on switch fl-2 are in the Development VLAN. How many broadcast domains and how
many collision domains are in the network? (Choose two.)
one broadcast domain
three broadcast domains
three collision domains
five broadcast domains
nine collision domains
ten collision domains
9. Refer to the exhibit. VLAN10 and VLAN20 have been created on SW_1 and SW_2
and switch ports have been assigned to the appropriate VLAN. Workstations in VLAN
10 can ping workstations in VLAN 10 that connect to either switch, but workstations in
VLAN 20 cannot ping workstations in VLAN 20 on the opposite switch. Based on the
output, what is most likely the problem?
FA 0/1 on SW_1 needs to be assigned to VLAN 20.
FA 0/1 on SW_2 needs to be assigned to VLAN 20.
VTP is not working properly between SW_1 and SW_2.
Interfaces FA0/1 on SW_1 and SW_2 need to be configured as trunk ports.
Interfaces FA0/3 on both switches need to be configured as access ports.
10. Refer to the exhibit. What can be concluded from the output that is shown?
The management VLAN is VLAN 99.
The only VLAN that can be applied to switch ports is VLAN 99.
The only VLANs that can be applied to switch ports are VLANs 1 and 99.
The switch will only be able to forward frames for hosts on the 10.99.0.0 network.
11. Refer to the exhibit and the following error message from the SwA switch.
