Question 1
Single choice

After configuring new data VLANs 1020 through 1030 on the VTP server, a network engineer notices that none of the VTP clients are receiving the updates.

What is the problem?

A.

The VTP server must be reloaded.

B.

The VTP version number must be set to version 3.

C.

After each update to the VTP server, it takes up to 4 hours propagate.

D.

VTP must be stopped and restarted on the server.

E.

Another switch in the domain has a higher revision number than the server.

Question 2
Single choice

A network engineer tries to configure storm control on an EtherChannel bundle.

What is the result of the configuration?

A.

The storm control settings will appear on the EtherChannel, but not on the associated physical ports.

B.

The configuration will be rejected because storm control is not supported for EtherChannel.

C.

The storm control configuration will be accepted, but will only be present on the physical interfaces.

D.

The settings will be applied to the EtherChannel bundle and all associated physical interfaces.

Question 3
Single choice

A network engineer configured a fault-tolerance link on Gigabit Ethernet links G0/1, G0/2, G0/3, and G0/4 between two switches using Ethernet port-channel.

Which action allows interface G0/1 to always actively forward traffic in the port-channel?

A.

Configure G0/1 as half duplex and G0/2 as full duplex.

B.

Configure LACP port-priority on G0/1 to 1.

C.

Configure LACP port-priority on G0/1 to 65535.

D.

LACP traffic goes through G0/4 because it is the highest interface ID.

Question 4
Single choice

In a Cisco switch, what is the default period of time after which a MAC address ages out and is discarded?

A.

100 seconds

B.

180 seconds

C.

300 seconds

D.

600 seconds

Question 5
Single choice

What is the size of the VLAN field inside an 802.1q frame?

A.

8-bit

B.

12-bit

C.

16-bit

D.

32-bit

Question 6
Single choice

By default, what is the state of port security on a switch?

A.

disabled

B.

on

C.

off

D.

learning

Question 7
Single choice

Refer to the exhibit.

Users of PC-1 experience slow connection when a webpage is requested from the server. To increase bandwidth, the network engineer configured an EtherChannel on interfaces Fa1/0 and Fa0/1 of the server farm switch, as shown here:

Server_Switch#sh etherchannel load-balance

EtherChannel Load-Balancing Operational State (src-mac):

Non-IP: Source MAC address

IPv4: Source MAC address

IPv6: Source IP address

Server_Switch#

However, traffic is still slow.

Which action can the engineer take to resolve this issue?

A.

Disable EtherChannel load balancing.

B.

Upgrade the switch IOS to IP services image.

C.

Change the load-balance method to dst-mac.

D.

Contact Cisco TAC to report a bug on the switch.

Question 8
Multiple choice

The network monitoring application alerts a network engineer of a client PC that is acting as a rogue DHCP server.

Which two commands help trace this PC when the MAC address is known? (Choose two.)

A.

switch# show mac address-table

B.

switch# show port-security

C.

switch# show ip verify source

D.

switch# show ip arp inspection

E.

switch# show mac address-table address <mac address>

Question 9
Single choice

Which statement describes what happens when a port configured with root guard receives a superior BPDU?

A.

The port goes into errdisabled state and stops forwarding traffic.

B.

The port goes into BPDU-inconsistent state and stops forwarding traffic.

C.

The port goes into loop-inconsistent state and stops forwarding traffic.

D.

The port goes into root-inconsistent state and stops forwarding traffic.

Question 10
Single choice

What effect does the mac address-table aging-time 180 command have on the MAC address-table?

A.

This is how long a dynamic MAC address will remain in the CAM table.

B.

The MAC address-table will be flushed every 3 minutes.

C.

The default timeout period will be 360 seconds.

D.

ARP requests will be processed less frequently by the switch.

E.

The MAC address-table will hold addresses 180 seconds longer than the default of 10 minutes.
