• Question 15:

  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?

  A. The new switches are using RSTP instead of legacy IEEE 802.1D STP.
  B. IEEE 802.1D STP and PortFast have been configured by default on all newly implemented Cisco Catalyst switches.
  C. The administrator has defined the switch as the root in the STP domain.
  D. The port roles have been adjusted based on the interface bandwidth and timers of the new Cisco Catalyst switches.
  A. The new switches are using RSTP instead of legacy IEEE 802.1D STP.

• Question 16:

  Ferris Plastics, Inc. is a medium sized company, with an enterprise network (access, distribution and core switches) that provides LAN connectivity from user PCs to corporate servers. The distribution switches are configured to use HSRP to provide a high availability solution.

  DSW1 -primary device for VLAN 101 VLAN 102 and VLAN 105

  DSW2 - primary device for VLAN 103 and VLAN 104

  A failure of GigabitEthemet1/0/1 on primary device should cause the primary device to release its status as the primary device, unless GigabitEthernet1/0/1 on backup device has also failed.

  Troubleshooting has identified several issues. Currently all interfaces are up. Using the running configurations and show commands, you have been asked to investigate and respond to the following question.

  

  What is the priority value of the VLAN 105 HSRP group on DSW2?

  A. 50
  B. 100
  C. 150
  D. 200
  B. 100

• Question 17:

  You have been asked to install and configure a new switch in a customer network. Use the console access to the existing and new switches to configure and verify correct device configuration.

  

  Examine the VTP configuration. You are required to configure private VLANs for a new server deployment connecting to the SW4 switch. Which of the following configuration steps will allow creating private VLANs?

  A. Disable VTP pruning on SW1 only
  B. Disable VTP pruning on SW2 only
  C. Disable VTP pruning on SW4 only
  D. Disable VTP pruning on SW2, SW4 and New_Switch
  E. Disable VTP pruning on New_Switch and SW4 only.
  C. Disable VTP pruning on SW4 only

• Question 18:

  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?

  A. The routers are connected via a Layer 2 switch.
  B. IP routing is disabled on neighboring devices.
  C. Cisco Express Forwarding is enabled locally.
  D. Cisco Discovery Protocol advertisements are inconsistent between the local and remote devices.
  A. The routers are connected via a Layer 2 switch.

• Question 19:

  Which statement describes one major issue that VTP can cause in an enterprise network when a new switch is introduced in the network in VTP mode server?

  A. It can cause network access ports to go into err-disabled state.
  B. It can cause a network-wide VLAN configuration change if the revision number on the new switch is higher.
  C. It can cause a network-wide VLAN configuration change if the revision number on the new switch is lower.
  D. It can cause routing loops.
  B. It can cause a network-wide VLAN configuration change if the revision number on the new switch is higher.

• Question 20:

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