CCNA1 Chapter 6 Exam - Online Assessment

1. Question

Which characteristic of the network layer in the OSI model allows carrying packets for multiple types of communications among many hosts?

the de-encapsulation of headers from lower layers
the selection of paths for and direct packets toward the destination
the ability to operate without regard to the data that is carried in each packet
the ability to manage the data transport between processes running on hosts

2. Question

What are two characteristics of IP? (Choose two.)

does not require a dedicated end-to-end connection
operates independently of the network media
retransmits packets if errors occur
re-assembles out of order packets into the correct order at the receiver end
guarantees delivery of packets

3. Question

When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary?

Connectionless acknowledgements are used to request retransmission.
Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host.
Network layer IP protocols manage the communication sessions if connection-oriented transport services are not available.
The best-effort delivery process guarantees that all packets that are sent are received.

4. Question

Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?

Time-to-Live
Sequence Number
Acknowledgment Number
Differentiated Services

5. Question

What IPv4 header field identifies the upper layer protocol carried in the packet?

Protocol
Identification
Version
Differentiated Services

6. Question

What is one advantage that the IPv6 simplified header offers over IPv4?

smaller-sized header
little requirement for processing checksums
smaller-sized source and destination IP addresses
efficient packet handling

7. Question

Refer to the exhibit.Which route from the PC1 routing table will be used to reach PC2?

CCNA1 v6.0 Chapter 6 Exam 002

8. Question

Refer to the exhibit. R1 receives a packet destined for the IP address 192.168.2.10. Out which interface will R1 forward the packet?

CCNA1 v6.0 Chapter 6 Exam 001

FastEthernet0/0
FastEthernet0/1
Serial0/0/0
Serial0/0/1

9. Question

What type of route is indicated by the code C in an IPv4 routing table on a Cisco router?

static route
default route
directly connected route
dynamic route that is learned through EIGRP

10. Question

What routing table entry has a next hop address associated with a destination network?

directly-connected routes
local routes
remote routes
C and L source routes

11. Question

Which statement describes a hardware feature of a Cisco 1941 router that has the default hardware configuration?

It does not have an AUX port.
It has three FastEthernet interfaces for LAN access.
It has two types of ports that can be used to access the console.
It does not require a CPU because it relies on Compact Flash to run the IOS.

12. Question

Following default settings, what is the next step in the router boot sequence after the IOS loads from flash?

Perform the POST routine.
Locate and load the startup-config file from NVRAM.
Load the bootstrap program from ROM.
Load the running-config file from RAM.

13. Question

What are two types of router interfaces? (Choose two.)

SVI
LAN
DHCP
Telnet
WAN

14. Question

Which two pieces of information are in the RAM of a Cisco router during normal operation? (Choose two.)

Cisco IOS
backup IOS file
IP routing table
basic diagnostic software
startup configuration file

15. Question

A router boots and enters setup mode. What is the reason for this?

The IOS image is corrupt.
Cisco IOS is missing from flash memory.
The configuration file is missing from NVRAM.
The POST process has detected hardware failure.

16. Question

What is the purpose of the startup configuration file on a Cisco router?

to facilitate the basic operation of the hardware components of a device
to contain the commands that are used to initially configure a router on startup
to contain the configuration commands that the router IOS is currently using
to provide a limited backup version of the IOS, in case the router cannot load the full featured IOS

17. Question

Which three commands are used to set up secure access to a router through a connection to the console interface? (Choose three.)

interface fastethernet 0/0
line vty 0 4
line console 0
enable secret cisco
login
password cisco

18. Question

Which characteristic describes an IPv6 enhancement over IPv4?

IPv6 addresses are based on 128-bit flat addressing as opposed to IPv4 which is based on 32-bit hierarchical addressing.
The IPv6 header is simpler than the IPv4 header is, which improves packet handling.
Both IPv4 and IPv6 support authentication, but only IPv6 supports privacy capabilities.
The IPv6 address space is four times bigger than the IPv4 address space.

19. Question

Open the PT Activity. The enable password on all devices is cisco.
Perform the tasks in the activity instructions and then answer the question.

For what reason is the failure occurring?

PC1 has an incorrect default gateway configured.
SW1 does not have a default gateway configured.
The IP address of SW1 is configured in a wrong subnet.
PC2 has an incorrect default gateway configured.

20. Question

Match the command with the device mode at which the command is entered. (Not all options are used.)
