• Question 162:

  A. The two workstations continue to communication without a default gateway configured.
  B. the command is unsupported on a trunk where VLANs have already been pruned manually.
  C. The running configuration displays switch port trunk allowed vlan 1-5 for Fa0/2.
  D. the two workstation stop communicating because they are on VLAN 5. Which is not allowed on the trunk.
  D. the two workstation stop communicating because they are on VLAN 5. Which is not allowed on the trunk.

• Question 163:

  Which AAA authorization method uses a vendor-neutral directory information protocol?

  A. LDAP
  B. RADIUS
  C. TACACS+
  D. Kerberos
  A. LDAP

• Question 164:

• Question 166:

  What is the maximum number of VLANs that can be assigned to an access switchport without a voice VLAN?

  B. 1
  C. 2
  D. 1024
  B. 1

  ---

  A standard (non-voice VLAN port) access switch port can belong to only a single VLAN. If more than one VLAN is needed, the port should be configured as a trunk port.

• Question 167:

  If you enable etherchannel guard misconfig on all trunk ports and after switch reboot found that 1 port in trunk is in err-disable state. What would be the cause?

  A. Due to EtherChannel misconfiguration this happened.
  B. http://certbus.com
  C. http://certbus.com
  D. http://certbus.com
  A. Due to EtherChannel misconfiguration this happened.

• Question 168:

  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.

  ---

  Since the number of existing VLANs differ on the switches (9 on A and 42 on B) we know that there is a problem with VTP or the trunking interfaces. The VTP domain names do match and they are both VTP servers so there are no issues there. The only viable solution is that there is a DTP issues and so you must instead manually configure the trunk ports between these two switches so that the VLAN information can be sent to each switch.

• Question 169:

  Your customer has asked you to come in and verify the operation of routers R1 and R2 which are configured to use HSRP. They have questions about how these two devices will perform in the event of a device failure.

  

  Refer to the configuration. For which configured VLAN are untagged frames sent over trunk between SW1 and SW2?

  A. VLAN1
  B. VLAN 99
  C. VLAN 999
  D. VLAN 40
  E. VLAN 50
  F. VLAN 200
  G. VLAN 300
  B. VLAN 99

  ---

  The native VLAN is used for untagged frames sent along a trunk. By issuing the "show interface trunk" command on SW1 and SW2 we see the native VLAN is 99.

  

• Question 170:

  Which command maximizes system resources for ACLs?

  A. sdm prefer default
  B. sdm prefer routing
  C. sdm prefer access
  D. sdm prefer vlan
  C. sdm prefer access
