CCNP Switch Exam Questions with Correct Answers |New Update 100% Verified By Experts
What is the maximum number of switches that can be stacked using Cisco StackWise? 9
A network engineer wants to add a new switch to an existing switch stack. Which configuration
must be added to the new switch before it can be added to the switch stack? No
configuration must be added.
What percentage of bandwidth is reduced when a stack cable is broken? 50%
Question 4
Which set of configurations will result in all ports on both switches successfully bundling into an
EtherChannel? Switch1
channel-group 1 mode desirable
switch2
channel-group 1 mode auto
Question 5
How can the traffic that is mirrored out the GigabitEthernet0/48 port be limited to only traffic
that is received or transmitted in VLAN 10 on the GigabitEthernet0/1 port? Apply the
monitor session filter globally to allow only traffic from VLAN 10.
Question 6
A network engineer wants to analyze all incoming and outgoing packets for an interface that is
connected to an access switch. Which three items must be configured to mirror traffic to a
packet sniffer that is connected to the distribution switch? (Choose three.) B. A remote
SPAN VLAN on the distribution and access layer switch
C. A monitor session on the access switch with a physical interface source and the remote SPAN
VLAN as the destination
D. A monitor session on the distribution switch with a remote SPAN VLAN as the source and
physical interface as the destination
,After an EtherChannel is configured between two Cisco switches, interface port channel 1 is in
the down/down state. Switch A is configured with channel-group 1 mode active, while Switch B
is configured with channel-group 1 mode desirable. Why is the EtherChannel bundle not
working? The switches are using mismatched EtherChannel negotiation modes.
An EtherChannel bundle has been established between a Cisco switch and a corporate web
server. The network administrator noticed that only one of the EtherChannel links is being
utilized to reach the web server. What should be done on the Cisco switch to allow for better
EtherChannel utilization to the corporate web server? Adjust the EtherChannel load-
balancing method based on source IP addresses.
Interface FastEthernet0/1 is configured as a trunk interface that allows all VLANs. This
command is configured globally:
monitor session 2 filter vlan 1 - 8, 39, 52
What is the result of the implemented command? Traffic from VLANs 1 to 8, 39, and 52 is
replicated to the SPAN destination port.
A network engineer notices inconsistent Cisco Discovery Protocol neighbors according to the
diagram that is provided. The engineer notices only a single neighbor that uses Cisco Discovery
Protocol, but it has several routing neighbor relationships. What would cause the output to
show only the single neighbor? The routers are connected via a Layer 2 switch.
After the implementation of several different types of switches from different vendors, a
network engineer notices that directly connected devices that use Cisco Discovery Protocol are
not visible. Which vendor-neutral protocol could be used to resolve this issue? Link Layer
Discovery Protocol
Several new switches have been added to the existing network as VTP clients. All of the new
switches have been configured with the same VTP domain, password, and version. However,
VLANs are not passing from the VTP server (existing network) to the VTP clients. What must be
done to fix this? Ensure that all switch interconnects are configured as trunks to allow VTP
information to be transferred.
, After implementing VTP, the extended VLANs are not being propagated to other VTP switches.
What should be configured for extended VLANs? Enable VTP version 3, which supports
extended VLAN propagation.
Question 14.
Switch A, B, and C are trunked together and have been properly configured for VTP. Switch C
receives VLAN information from the VTP server Switch A, but Switch B does not receive any
VLAN information. What is the most probable cause of this behavior? Switch B is configured
in transparent mode.
Question 15
Switch A, B, and C are trunked together and have been properly configured for VTP. Switch B
has all VLANs, but Switch C is not receiving traffic from certain VLANs. What would cause this
issue? VTP pruning is configured globally on all switches and it removed VLANs from the
trunk interface that is connected to Switch C.
After the recent upgrade of the switching infrastructure, the network engineer notices that the
port roles that were once "blocking" are now defined as "alternate" and "backup." What is the
reason for this change? The new switches are using RSTP instead of legacy IEEE 802.1D STP.
An administrator recently configured all ports for rapid transition using PortFast. After testing,
it has been determined that several ports are not transitioning as they should. What is the
reason for this? STP is unable to achieve rapid transition for trunk links.
Which technique automatically limits VLAN traffic to only the switches that require it? VTP
pruning
What effect does the mac address-table aging-time 180 command have on the MAC address-
table? This is how long a dynamic MAC address will remain in the CAM table.
