A client is using SLAAC to obtain an IPv6 address for its interface. After an
address has been generated and applied to the interface, what must the client
do before it can begin to use this IPv6 address?
It must send an ICMPv6 Router Solicitation message to determine what default
gateway it should use.
,It must send a DHCPv6 INFORMATION-REQUEST message to request the
address of the DNS server.
It must send a DHCPv6 REQUEST message to the DHCPv6 server to request
permission to use this address.
It must send an ICMPv6 Neighbor Solicitation message to ensure that the
address is not already in use on the network. - ANSWER It must send an ICMPv6
Neighbor Solicitation message to ensure that the address is not already in use
on the network.
What mechanism is used by a router to prevent a received IPv4 packet from
traveling endlessly on a network?
A.It checks the value of the TTL field and if it is 100, it discards the packet and
sends a Destination Unreachable message to the source host.
B.It increments the value of the TTL field by 1 and if the result is 100, it discards
the packet and sends a Parameter Problem message to the source host.
C.It checks the value of the TTL field and if it is 0, it discards the packet and
sends a Destination Unreachable message to the source host.
D.It decrements the value of the TTL field by 1 and if the result is 0, it discards
the packet and sends a Time Exceeded message to the source host. - ANSWER
D.It decrements the value of the TTL field by 1 and if the result is 0, it discards
the packet and sends a Time Exceeded message to the source host.

F.extensive cabling - ANSWER B.security
C.interference
D.coverage area
A network administrator notices that some newly installed Ethernet cabling is
carrying corrupt and distorted data signals. The new cabling was installed in the
ceiling close to fluorescent lights and electrical equipment. Which two factors
may interfere with the copper cabling and result in signal distortion and data
corruption? (Choose two.)
A.EMI
B.signal attenuation
C.crosstalk
D.RFI
E.extended length of cabling - ANSWER A.EMI
D.RFI
, Data is being sent from a source PC to a destination server. Which three
statements correctly describe the function of TCP or UDP in this situation?
(Choose three.)
A.TCP is the preferred protocol when a function requires lower network
overhead.
B.The source port field identifies the running application or service that will
handle data returning to the PC.
C.The TCP source port number identifies the sending host on the network.
D.UDP segments are encapsulated within IP packets for transport across the
network.
E.The UDP destination port number identifies the application or service on the
server which will handle the data.
F.The TCP process running on the PC randomly selects the destination port
when establishing a session with the server - ANSWER B.The source port field
identifies the running application or service that will handle data returning to the
PC.
A group of Windows PCs in a new subnet has been added to an Ethernet
network. When testing the connectivity, a technician finds that these PCs can
access local network resources but not the Internet resources. To troubleshoot
the problem, the technician wants to initially confirm the IP address and DNS

three Windows CLI commands and utilities will provide the necessary
information? (Choose three.)
A.netsh interface ipv6 show neighbor
B.arp -a
C.tracert
D.ping
E.ipconfig
F.nslookup
G.telnet - ANSWER D.ping
