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
