  A. Interface ID number
  B. reliability of each local interface
  C. local OSPF area
  D. number of interfaces in the area
  E. transmit and receive rates of each local interface

• Question 283:

  Which two statements about using the CHAP authentication mechanism in a PPP link are true? (Choose two.)

  A. CHAP uses a two-way handshake.
  B. CHAP uses a three-way handshake.
  C. CHAP authentication periodically occurs after link establishment.
  D. CHAP authentication passwords are sent in plaintext.
  E. CHAP authentication is performed only upon link establishment.
  F. CHAP has no protection from playback attacks.
  B. CHAP uses a three-way handshake.
  C. CHAP authentication periodically occurs after link establishment.

  CHAP is an authentication scheme used by Point to Point Protocol (PPP) servers to validate the identity of remote clients. CHAP periodically verifies the identity of the client by using a three-way handshake. This happens at the time of establishing the initial link (LCP), and may happen again at any time afterwards. The verification is based on a shared secret (such as the client user's password).

• Question 284:

  Which item represents the standard IP ACL?

  A. access-list 110 permit ip any any
  B. access-list 50 deny 192.168.1.1 0.0.0.255
  C. access list 101 deny tcp any host 192.168.1.1
  D. access-list 2500 deny tcp any host 192.168.1.1 eq 22
  B. access-list 50 deny 192.168.1.1 0.0.0.255

  ---

  The standard access lists are ranged from 1 to 99 and from 1300 to 1999 so only access list 50 is a standard access list.

• Question 285:

  Refer to the exhibit.

  

  How should the FastEthernet0/1 ports on the switches that are shown in the exhibit be configured to allow connectivity between all devices?

  A. The ports only need to be connected by a crossover cable.
  B. SwitchX(config)# interface fastethernet 0/1 SwitchX(config-if)# switchport mode trunk
  C. SwitchX(config)# interface fastethernet 0/1 SwitchX(config-if)# switchport mode access SwitchX(config-if)# switchport access vlan 1
  D. SwitchX(config)# interface fastethernet 0/1 SwitchX(config-if)# switchport mode trunk SwitchX(config-if)# switchport trunk vlan 1 SwitchX(config-if)# switchport trunk vlan 10 SwitchX(config-if)# switchport trunk vlan 20
  B. SwitchX(config)# interface fastethernet 0/1 SwitchX(config-if)# switchport mode trunk

  ---

  IN order for multiple VLANs to cross switches, the connection between the switches must be a trunk. The "switchport mode trunk" command is all that is needed, the individual VLANs should not be listed over that trunk interface.

• Question 286:

  B. a greater number in hsrp group field
  B. a greater number in hsrp group field

• Question 287:

  A. the highest MAC address
  B. the lowest MAC address
  C. the highest port priority
  D. the lowest system ID
  E. the lowest switch priority
  B. the lowest MAC address
  E. the lowest switch priority

• Question 288:

  Refer to exhibit. What Administrative distance has route to 192.168.10.1 ?

  

  A. 1
  B. 90
  C. 110

  A. They use ICMPv6 type 134.
  B. The advertised prefix length must be 64 bits.
  C. The advertised prefix length must be 48 bits.
  D. They are sourced from the configured IPv6 interface address.
  E. Their destination is always the link-local address of the neighboring node.
  A. They use ICMPv6 type 134.
  B. The advertised prefix length must be 64 bits.

• Question 290:

  Which command can you enter to determine whether serial interface 0/2/0 has been configured using HDLC encapsulation?

  A. router#show platform
  B. router#show interfaces Serial 0/2/0
  C. router#show ip interface s0/2/0
  D. router#\show ip interface brief
  B. router#show interfaces Serial 0/2/0
