Q1. Refer to the exhibit.

The network switches for two companies have been connected and manually configured for the required VLANs, but users in company A are not able to access network resources in company B when DTP is enabled. Which action resolves this problem?

A. Delete vlan.dat and ensure that the switch with lowest MAC address is the VTP server.

B. Disable DTP and document the VTP domain mismatch.

C. Manually force trunking with switchport mode trunk on both switches.

D. Enable the company B switch with the vtp mode server command.

Q3. CORRECT TEXTScenario:

You work for SWITCH.com. They have just added a new switch (SwitchB) to the existing network as shown in the topology diagram.

RouterA is currently configured correctly and is providing the routing function for devices on SwitchA and SwitchB. SwitchA is currently configured correctly, but will need to be modified to support the addition of SwitchB. SwitchB has a minimal configuration. You have been tasked with competing the needed configuring of SwitchA and SwitchB. SwitchA and SwitchB use Cisco as the enable password.

Configuration Requirements for SwitchA

The VTP and STP configuration modes on SwitchA should not be modified.

u2022 SwitchA needs to be the root switch for vlans 11, 12, 13, 21, 22 and 23. All other vlans should be left are their default values.

Configuration Requirements for SwitchB

u2022 Vlan 21

u2711 Name: Marketing

u2711 will support two servers attached to fa0/9 and fa0/10

u2022 Vlan 22

u2711 Name: Sales

u2711 will support two servers attached to fa0/13 and fa0/14

u2022 Vlan 23

o Name: Engineering

o will support two servers attached to fa0/15 and fa0/16

u2022 Access ports that connect to server should transition immediately to forwarding state upon detecting the connection of a device.

u2022 SwitchB VTP mode needs to be the same as SwitchA.

u2022 SwitchB must operate in the same spanning tree mode as SwitchA

u2022 No routing is to be configured on SwitchB

u2022 Only the SVI vlan 1 is to be configured and it is to use address 192.168.1.11/24

Inter-switch Connectivity Configuration Requirements

u2022 For operational and security reasons trunking should be unconditional and Vlans 1, 21, 22 and 23 should tagged when traversing the trunk link.

u2022 The two trunks between SwitchA and SwitchB need to be configured in a mode that allows for the maximum use of their bandwidth for all vlans. This mode should be done with a non-proprietary protocol, with SwitchA controlling activation.

u2022 Propagation of unnecessary broadcasts should be limited using manual pruning on this trunk link.

Q4. The command storm-control broadcast level 75 65 is configured under the switch port connected to the corporate mail server. In which three ways does this command impact the traffic? (Choose three.)

A. SNMP traps are sent by default when broadcast traffic reaches 65% of the lower-level threshold.

B. The switchport is disabled when unicast traffic reaches 75% of the total interface bandwidth.

C. The switch resumes forwarding broadcasts when they are below 65% of bandwidth.

D. Only broadcast traffic is limited by this particular storm control configuration.

E. Multicast traffic is dropped at 65% and broadcast traffic is dropped at 75% of the total interface bandwidth.

F. The switch drops broadcasts when they reach 75% of bandwidth.

Q9. Which statement is correct about 802.1Q trunking?

A. Both switches must be in the same VTP domain.

B. The encapsulation type of both ends of the trunk does not have to match.

C. The native VLAN on both ends of the trunk must be VLAN 1.

D. 802.1Q trunking can only be configured on a Layer 2 port.

E. In 802.1Q trunking, all VLAN packets are tagged on the trunk link, except the native VLAN.

Q10. Which statement about using native VLANs to carry untagged frames is true?

A. Cisco Discovery Protocol version 2 carries native VLAN information, but version 1 does not.

B. Cisco Discovery Protocol version 1 carries native VLAN information, but version 2 does not.

C. Cisco Discovery Protocol version 1 and version 2 carry native VLAN information.

D. Cisco Discovery Protocol version 3 carries native VLAN information, but versions 1 and 2 do not.

A. Normal UDLD operations that prevent traffic loops.

B. UDLD port is configured in aggressive mode.

C. UDLD is enabled globally.

D. UDLD timers are inconsistent.
