• Question 865:

  An administrator is trying to ping and telnet from SwitchC to RouterC with the results shown below.

  

  Click the console connected to RouterC and issue the appropriate commands to answer the questions.

  

  

  What would be the effect of issuing the command ip access-group 114 in to the fa0/0 interface?

  A. Attempts to telnet to the router would fail.
  B. It would allow all traffic from the 10.4.4.0 network.
  C. IP traffic would be passed through the interface but TCP and UDP traffic would not.
  D. Routing protocol updates for the 10.4.4.0 network would not be accepted from the fa0/0 interface.
  B. It would allow all traffic from the 10.4.4.0 network.

  ---

  From the output of access-list 114: access-list 114 permit ip 10.4.4.0 0.0.0.255 any we can easily understand that this access list allows all traffic (ip) from 10.4.4.0/24 network

• Question 866:

  Refer to the exhibit.

  

  What statement is true of the configuration for this network?

  A. The configuration that is shown provides inadequate outside address space for translation of the number of inside addresses that are supported.
  B. Because of the addressing on interface FastEthernet0/1, the Serial0/0 interface address will not support the NAT configuration as shown.
  C. The number 1 referred to in the ip nat inside source command references access-list number 1.
  D. ExternalRouter must be configured with static routes to networks 172.16.1.0/24 and 172.16.2.0/24.
  C. The number 1 referred to in the ip nat inside source command references access-list number 1.

  ---

  The "list 1 refers to the access-list number 1.

• Question 867:

  C. Router(config)# router eigrp 100 Router(config-router)# network 192.168.10.0 Router(config-router)# network 192.168.20.0
  D. Switch1(config)# vlan database Switch1(config-vlan)# vtp domain XYZ Switch1(config-vlan)# vtp server
  E. Switch1(config)# interface fastethernet 0/1 Switch1(config-if)# switchport mode trunk
  F. Switch1(config)# interface vlan 1 Switch1(config-if)# ip default-gateway 192.168.1.1

  The router will need to use subinterfaces, where each subinterface is assigned a VLAN and IP address for each VLAN. On the switch, the connection to the router need to be configured as a trunk using the switchport mode trunk command and it will need a default gateway for VLAN 1.

• Question 870:

  Which two link protocols are used to carry multiple VLANs over a single link? (Choose two.)

  A. VTP
  B. 802.1q
  C. IGP
  D. ISL
  E. 802.3u
  B. 802.1q
  D. ISL

  Cisco switches can use two different encapsulation types for trunks, the industry standard 802.1q or the Cisco proprietary ISL. Generally, most network engineers prefer to use 802.1q since it is standards based and will interoperate with other vendors.
