CCNA1 Chapter 6 Exam & Answer

Soal Beserta jawaban Latihan CCNA 1
CHAPTER 6
STMIK Nusa Mandiri Jakarta



1. Which characteristic of the network layer in the OSI model allows carrying packets for multiple types of communications among many hosts?
the ability to manage the data transport between processes running on hosts
the de-encapsulation of headers from lower layers
the ability to operate without regard to the data that is carried in each packet
the selection of paths for and direct packets toward the destination



2. Which three commands are used to set up secure access to a router through a connection to the console interface? (Choose three.)
enable secret cisco
interface fastethernet 0/0
login
line console 0
password cisco
line vty 0 4



3. For what reason is the failure occurring?​
The IP address of SW1 is configured in a wrong subnet.​
PC1 has an incorrect default gateway configured.
SW1 does not have a default gateway configured.
PC2 has an incorrect default gateway configured.



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



5. Which two pieces of information are in the RAM of a Cisco router during normal operation? (Choose two.)
startup configuration file
Cisco IOS
basic diagnostic software
backup IOS file
IP routing table



6. Which statement describes a hardware feature of a Cisco 1941 router that has the default hardware configuration?
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.
It has three FastEthernet interfaces for LAN access.
It does not have an AUX port.



7. What are two characteristics of IP? (Choose two.)
does not require a dedicated end-to-end connection
retransmits packets if errors occur
operates independently of the network media
re-assembles out of order packets into the correct order at the receiver end
guarantees delivery of packets



8. What routing table entry has a next hop address associated with a destination network?
directly-connected routes
C and L source routes
local routes
remote routes



9. What IPv4 header field identifies the upper layer protocol carried in the packet?
Version
Protocol
Identification
Differentiated Services



10.
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?
FastEthernet0/0
Serial0/0/0
Serial0/0/1
FastEthernet0/1



11. What type of route is indicated by the code C in an IPv4 routing table on a Cisco router?
directly connected route
static route
default route
dynamic route that is learned through EIGRP



12. When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary?
Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host.
The best-effort delivery process guarantees that all packets that are sent are received.
Network layer IP protocols manage the communication sessions if connection-oriented transport services are not available.
Connectionless acknowledgements are used to request retransmission.



13. What is the purpose of the startup configuration file on a Cisco router?
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
to contain the commands that are used to initially configure a router on startup
to facilitate the basic operation of the hardware components of a device



14. Option 5: enable. Press spacebar to enter matching mode. 
Match the command with the device mode at which the command is entered. (Not all options are used.)


R1(config)#
service password-encryption
R1>
enable
R1(config-router)#

R1#
copy running-config startup-config
R1(config-line)#
login
R1(config-if)#
ip address 192.168.4.4 255.255.255.0




15. A router boots and enters setup mode. What is the reason for this?
The POST process has detected hardware failure.
The IOS image is corrupt.
Cisco IOS is missing from flash memory.
The configuration file is missing from NVRAM.




16. Following default settings, what is the next step in the router boot sequence after the IOS loads from flash?
Load the running-config file from RAM.
Locate and load the startup-config file from NVRAM.
Load the bootstrap program from ROM.
Perform the POST routine.



17. Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?
Differentiated Services
Sequence Number
Acknowledgment Number
Time-to-Live



18. What is one advantage that the IPv6 simplified header offers over IPv4?
efficient packet handling
little requirement for processing checksums
smaller-sized source and destination IP addresses
smaller-sized header



19.
Refer to the exhibit.Which route from the PC1 routing table will be used to reach PC2?





20. What are two types of router interfaces? (Choose two.)
DHCP
SVI
Telnet
WAN
LAN
