• Question 242:

  Which two components are used to identify a neighbor in a BGP configuration? (Choose two.)

  A. autonomous system number
  B. version number
  C. router ID
  D. subnet mask
  E. IP address
  A. autonomous system number
  E. IP address

  Use the show ip bgp neighbors (registered customers only) command to display information about the TCP and Border Gateway Protocol (BGP) connections and verify if the BGP peer is established. The output of the show ip bgp neighbors command below shows the BGP state as 'Established', which indicates that the BGP peer relationship has been established successfully. R1-AGS# show ip bgp neighbors | include BGP BGP neighbor is 10.10.10.2, remote AS 400, internal link BGP version 4, remote router ID 2.2.2.2 BGP state = Established, up for 00:04:20 BGP table version 1, neighbor version 1 R1-AGS# The show ip bgp neighbors command has been used above with the modifier | include BGP. This makes the output more readable by filtering the the command output and displaying the relevant parts only. In addition, the show ip bgp summary (registered customers only) command can also be used to display the status of all BGP connections, as shown below. R1-AGS(9)# show ip bgp summary BGP router identifier 10.1.1.2, local AS number 400 BGP table version is 1, main routing table version 1

• Question 243:

  Which statement about switch access ports is true?

  A. They drop packets with 802.1Q tags.
  B. A VLAN must be assigned to an access port before it is created.
  C. They can receive traffic from more than one VLAN with no voice support
  D. By default, they carry traffic for VLAN 10.
  A. They drop packets with 802.1Q tags.

  ---

  "If an access port receives a packet with an 802.1Q tag in the header other than the access VLAN value, that port drops the packet without learning its MAC source address."

• Question 244:

  Which two circumstances can cause collision domain issues on VLAN domain? (Choose two.)

  A. duplex mismatches on Ethernet segments in the same VLAN
  B. multiple errors on switchport interfaces
  C. congestion on the switch inband path
  D. a failing NIC in an end device
  E. an overloaded shared segment
  A. duplex mismatches on Ethernet segments in the same VLAN
  C. congestion on the switch inband path

  Collision Domains A collision domain is an area of a single LAN where end stations contend for access to the network because all end stations are connected to a shared physical medium. If two connected devices transmit onto the media at the same time, a collision occurs. When a collision occurs, a JAM signal is sent on the network, indicating that a collision has occurred and that devices should ignore any fragmented data associated with the collision. Both sending devices back off sending their data for a random amount and then try again if the medium is free for transmission. Therefore, collisions effectively delay transmission of data, lowering the effective throughput available to a device. The more devices that are attached to a collision domain, the greater the chances of collisions; this results in lower bandwidth and performance for each device attached to the collision domain. Bridges and switches terminate the physical signal path of a collision domain, allowing you to segment separate collision domains, breaking them up into multiple smaller pieces to provide more bandwidth per user within the new collision domains formed.

  B. R2 and R3
  C. R3 and S2
  D. R1 and R3
  E. R1, S1, S2, and R3
  C. R3 and S2

  D. Messages are stored external to the device
  E. The size of the log file is dependenet on the resources of the device
  B. Messages are stored in the internal memory of device
  C. Messages can be erased when device reboots
