Module 13 Flashcards
Which two types of ICMP messages
are common to both ICMPv4 and
ICMPv6? (Choose two.)
* Destination or Service
Unreachable
* Hostname resolution
* IP configuration
* Source Unreachable
* Time exceeded
- Destination or Service
Unreachable - Time exceeded
Which type of ICMPv6 message would
a host send to acquire an IPv6
configuration when booting up?
* Neighbor Advertisement (NA)
message
* Neighbor Solicitation (NS)
message
* Router Advertisement (RA)
message
* Router Solicitation (RS) message
- Router Solicitation (RS) message
What is a function of the tracert
command that differs from the ping
command when they are used on a
workstation?
* The tracert command reaches the
destination faster.
* The tracert command shows the
information of routers in the path.
* The tracert command sends one
ICMP message to each hop in the
path.
* The tracert command is used to
test the connectivity between two
devices.
- The tracert command shows the
information of routers in the path.
Which ICMP message is used by the
traceroute utility during the process of
finding the path between two end
hosts?
* redirect
* ping
* time exceeded
* destination unreachable
- time exceeded
Which two things can be determined
by using the ping command? (Choose
two.)
* the number of routers between the
source and destination device
* the IP address of the router nearest
the destination device
* the average time it takes a packet
to reach the destination and for
the response to return to the
source
* the destination device is reachable
through the network
* the average time it takes each
router in the path between source
and destination to respond
- the average time it takes a packet
to reach the destination and for
the response to return to the
source - the destination device is reachable
through the network
Which statement describes a
characteristic of the traceroute utility?
* It sends four Echo Request
messages.
* It utilizes the ICMP Source Quench
messages.
* It is primarily used to test
connectivity between two hosts.
* It identifies the routers in the path
from a source host to a destination
host.
- It identifies the routers in the path
from a source host to a destination
host.
. Which utility uses the Internet Control
Messaging Protocol (ICMP)?
* RIP
* DNS
* ping
* NTP
- ping
. A network administrator can
successfully ping the server at
www.cisco.com, but cannot ping the
company web server located at an ISP
in another city. Which tool or
command would help identify the
specific router where the packet was
lost or delayed?
* ipconfig
* netstat
* telnet
* traceroute
- traceroute
Which protocol is used by IPv4 and
IPv6 to provide error messaging?
* ICMP
* NDP
* ARP
* DHCP
- ICMP
.What message is sent by a host to
check the uniqueness of an IPv6
address before using that address?
* neighbor solicitation
* ARP request
* echo request
* router solicitation
- neighbor solicitation
A technician is troubleshooting a
network where it is suspected that a
defective node in the network path is
causing packets to be dropped. The
technician only has the IP address of
the end point device and does not
have any details of the intermediate
devices. What command can the
technician use to identify the faulty
node?
* tracert
* ping
* ipconfig /flushdns
* ipconfig /displaydns
- tracert
A user who is unable to connect to the
file server contacts the help desk. The
helpdesk technician asks the user to
ping the IP address of the default
gateway that is configured on the
workstation. What is the purpose for
this ping command?
* to obtain a dynamic IP address
from the server
* to request that gateway forward
the connection request to the file
server
* to test that the host has the
capability to reach hosts on other
networks
* to resolve the domain name of the
file server to its IP address
- to test that the host has the
capability to reach hosts on other
networks
A user calls to report that a PC cannot
access the internet. The network
technician asks the user to issue the
command ping 127.0.0.1 in a
command prompt window. The user
reports that the result is four positive
replies. What conclusion can be
drawn based on this connectivity test?
* The PC can access the network.
The problem exists beyond the
local network.
* The IP address obtained from the
DHCP server is correct.
* The PC can access the Internet.
However, the web browser may not
work.
* The TCP/IP implementation is
functional.
- The TCP/IP implementation is
functional.
Which command can be used to test
connectivity between two devices
using echo request and echo reply
messages?
* netstat
* traceroute
* ICMP
* ping
- ping
What field content is used by ICMPv6
to determine that a packet has
expired?
* TTL field
* CRC field
* Hop Limit field
* Time Exceeded field
- Hop Limit field
