of 22. What service is the client requesting?
-SSH
-TFTP
-DHCP
-DNS - ✔✔SSH
Refer to the exhibit. What does the value of the window size specify?
window size: 9017
-the amount of data that can be sent at one time
-the amount of data that can be sent before an acknowledgment is required
-the total number of bits received during this TCP session
-a random number that is used in establishing a connection with the 3-way
handshake - ✔✔The amount of data that can be sent before an acknowledgment
is required
To which TCP port group does the port 414 belong?
-well-known
-private or dynamic
-public
-registered - ✔✔well-known
,Refer to the exhibit. An administrator is trying to configure the switch but
receives the error message that is displayed in the exhibit. What is the problem?
Switch> config t
% Invalid input
-The entire command, configure terminal, must be used.
-The administrator is already in global configuration mode.
-The administrator must first enter privileged EXEC mode before issuing the
command.
-The administrator must connect via the console port to access global
configuration mode. - ✔✔The administrator must first enter privileged EXEC
mode before issuing the command.
What is a user trying to determine when issuing a ping 10.1.1.1 command on a
PC?
-if the TCP/IP stack is functioning on the PC without putting traffic on the wire
-if there is connectivity with the destination device
-the path that traffic will take to reach the destination
-what type of device is at the destination - ✔✔if there is connectivity with the
destination device
What is a characteristic of a switch virtual interface (SVI)?
-An SVI is created in software and requires a configured IP address and a subnet
mask in order to provide remote access to the switch.
-Although it is a virtual interface, it needs to have physical hardware on the device
associated with it.
-SVIs do not require the no shutdown command to become enabled.
, -SVIs come preconfigured on Cisco switches. - ✔✔An SVI is created in software
and requires a configured IP address and a subnet mask in order to provide
remote access to the switch.
ClI - ✔✔Users interact with the operating system by typing commands
GUI - ✔✔enables the user to interact with the operating system by pointing and
clicking
Kernel - ✔✔The part of the OS that interacts directly with the device hardware
Shell - ✔✔the part of the operating system that interfaces with applications and
the user
What happens when a switch receives a frame and the calculated CRC value is
different than the value that is in the FCS field?
-The switch notifies the source of the bad frame.
-The switch places the new CRC value in the FCS field and forwards the frame.
-The switch drops the frame.
-The switch floods the frame to all ports except the port through which the frame
arrived to notify the hosts of the error. - ✔✔The switch drops the frame
Two network engineers are discussing the methods used to forward frames
through a switch. What is an important concept related to the cut-through
method of switching?
-The fragment-free switching offers the lowest level of latency.
