  A. On the interface configuration mode; (config-if)# ip dhcp snooping trust
  B. On the global configuration mode; (config)# ip dhcp snooping information option allow-untrusted
  C. On the interface configuration mode; (config-if)# ip dhcp snooping information option allow-untrusted
  D. On the interface configuration mode; (config-if)# ip dhcp snooping granted
  E. On the global configuration mode; (config)# ip dhcp snooping information option enable-untrusted
  F. On the interface configuration mode; (config-if)# ip dhcp snooping information option enable-untrusted
  A. On the interface configuration mode; (config-if)# ip dhcp snooping trust
  B. On the global configuration mode; (config)# ip dhcp snooping information option allow-untrusted
  C. On the interface configuration mode; (config-if)# ip dhcp snooping information option allow-untrusted

• Question 312:

  Which two protocols can be automatically negotiated between switches for trunking? (Choose two.)

  A. PPP
  B. DTP
  C. ISL
  D. HDLC
  E. DLCI
  F. DOT1Q
  C. ISL
  F. DOT1Q

  ---

  Switches such as the Catalyst 3550 that are capable of either 802.1Q or ISL trunking encapsulation, the switchport trunk encapsulation [dot1q | isl | negotiate] interface command must be used prior to the switchport mode trunk command.

• Question 313:

  Drag and Drop

  Select and Place:

  

  

• Question 314:

  A network engineer has just deployed a non-Cisco device in the network and wants to get information about it from a connected device. Cisco Discovery Protocol is not supported, so the open standard protocol must be configured. Which

  protocol does the network engineer configure on both devices to accomplish this?

  A. IRDP
  B. LLDP
  C. NDP
  D. LLTD
  B. LLDP

  ---

  The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol in the Internet Protocol Suite used by network devices for advertising their identity, capabilities, and neighbors on an IEEE 802 local area network, principally wired Ethernet. LLDP performs functions similar to several proprietary protocols, such as the Cisco Discovery Protocol (CDP). Reference: http://en.wikipedia.org/wiki/ Link_Layer_Discovery_Protocol

  spanning-tree backbonefast

  The question was something like what does the configuration do?

  A. It used extended VLAN
  B. It used to protect Root switch
  C. It enables the switch to set dynamic extended System IDs.
  C. It enables the switch to set dynamic extended System IDs.

• Question 316:

  Where should the Root Guard be implemented in the network topology that Cisco recommends? (Choose two.)

  A. All non-root ports of the Access Switches.
  B. Downstream links from Distribution to Access Switches
  C. Access Switches to uplink ports to Distribution Switches
  D. On Layer 3 Switches.
  A. All non-root ports of the Access Switches.
  B. Downstream links from Distribution to Access Switches

• Question 317:

  Which two commands verify the DHCP snooping configuration on a device? (Choose two.)

  A. show ip dhcp pool
  B. show ip dhcp relay
  C. show ip dhcp snooping
  D. show running-config | include snooping
  E. clear ip dhcp snooping binding
  C. show ip dhcp snooping
  D. show running-config | include snooping

• Question 318:

  A question about non-default native VLAN vs trunk with two choices. (Choose two.) (We want non default native VLAN vs trunk something like that...)

  A. encapsulation dot1q 99 native
  B. switchport access vlan 1
  C. switchport mode trunk
  D. switchport access vlan 99
  A. encapsulation dot1q 99 native
  C. switchport mode trunk

  B. dynamic trunk port
  C. dynamic access port
  D. http://certbus.com
  A. static trunk port

• Question 320:

  Refer to the exhibit.

  

  What is the effect of the given configuration?

  A. It enables the switch to become the spanning-tree root bridge.
  B. It enables the reduced MAC address feature.
  C. It enables spanning-tree to create dynamic system IDs.
  D. It enables extended VLANs.
  C. It enables spanning-tree to create dynamic system IDs.
