A new network administrator has been asked to enter a banner message
on a Cisco device. What is the fastest way a network administrator could
test whether the banner is properly configured? - Precise Answer
✔✔Exit privileged EXEC mode and press Enter.
What happens when the transport input ssh command is entered on the
switch vty lines? - Precise Answer ✔✔Communication between the
switch and remote users is encrypted.
What is the subnet ID associated with the IPv6 address
2001:DA48:FC5:A4:3D1B::1/64? - Precise Answer
✔✔2001:DA48:FC5:A4::/64
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? - Precise
Answer ✔✔It must send an ICMPv6 Neighbor Solicitation message to
ensure that the address is not already in use on the network.
Which range of link-local addresses can be assigned to an IPv6-enabled
interface? - Precise Answer ✔✔FE80::/10
What mechanism is used by a router to prevent a received IPv4 packet
from traveling endlessly on a network? - Precise Answer ✔✔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.
A network administrator is designing the layout of a new wireless
network. Which three areas of concern should be accounted for when
building a wireless network? (Choose three.) - Precise Answer
✔✔security
interference
coverage area
Refer to the exhibit. What is wrong with the displayed termination? -
Precise Answer ✔✔The untwisted length of each wire is too long.
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.) - Precise
Answer ✔✔EMI
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.) - Precise Answer ✔✔The source port field
identifies the running application or service that will handle data
returning to the PC.
, UDP segments are encapsulated within IP packets for transport across
the network.
The UDP destination port number identifies the application or service on
the server which will handle the data.
Match the application protocols to the correct transport protocols. -
Precise Answer ✔✔TCP:
FTP
HTTP
SMTP
UDP:
DHCP
TFTP
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 configurations on the PCs, and also verify connectivity
to the local router. Which three Windows CLI commands and utilities
will provide the necessary information? (Choose three.) - Precise
Answer ✔✔ping
ipconfig
