  Explanation: A source port, also called a monitored port, is a switched or routed port that you monitor for network traffic analysis. In a single local SPAN session or RSPAN source session, you can monitor source port traffic, such as received

  (Rx), transmitted (Tx), or bidirectional (both). The switch supports any number of source ports (up to the maximum number of available ports on the switch) and any number of source VLANs.

  A source port has these characteristics:

  It can be any port type, such as EtherChannel, Fast Ethernet, Gigabit Ethernet, and so forth.

  It can be monitored in multiple SPAN sessions.

  It cannot be a destination port.

  Each source port can be configured with a direction (ingress, egress, or both) to monitor. For EtherChannel sources, the monitored direction applies to all physical ports in the group. Source ports can be in the same or different VLANs. For

  VLAN SPAN sources, all active ports in the source VLAN are included as source ports.

• Question 574:

• Question 575:

  Refer to the exhibit.

  

  What is the effect of the configuration that is shown?

  A. It configures SSH globally for all logins.
  B. It tells the router or switch to try to establish an SSh connection first and if that fails to use Telnet.
  C. It configures the virtual terminal lines with the password 030752180500.
  D. It configures a Cisco network device to use the SSH protocol on incoming communications via the virtual terminal ports.
  E. It allows seven failed login attempts before the VTY lines are temporarily shutdown.
  D. It configures a Cisco network device to use the SSH protocol on incoming communications via the virtual terminal ports.

  Secure Shell (SSH) is a protocol which provides a secure remote access connection to network devices. Communication between the client and server is encrypted in both SSH version 1 and SSH version 2. If you want to prevent non-SSH connections, add the "transport input ssh" command under the lines to limit the router to SSH connections only.

  Straight (non-SSH) Telnets are refused.

• Question 577:

  After you enable routing on a switch, which two tasks must you perform to configure inter-VLAN routing on an SVI interface? (Choose two)

  A. Configure a routing protocol to route the traffic
  B. Configure the ip default-gateway command on the switch
  C. Configure an ACL to route only the necessary traffic
  D. Configure an IP address on each VLAN interface.
  E. Ensure that the target VLANs are present in the switch database
  C. Configure an ACL to route only the necessary traffic
  E. Ensure that the target VLANs are present in the switch database

• Question 578:

  Refer to the exhibit.

  

  At the end of an RSTP election process, which access layer switch port will assume the discarding role?

  A. Switch3, port fa0/1
  B. Switch3, port fa0/12
  C. Switch4, port fa0/11
  D. Switch4, port fa0/2
  E. Switch3, port Gi0/1
  F. Switch3, port Gi0/2
  C. Switch4, port fa0/11

  ---

  In this question, we only care about the Access Layer switches (Switch3 and 4). Switch 3 has a lower bridge ID than Switch 4 (because the MAC of Switch3 is smaller than that of Switch4) so both ports of Switch3 will be in forwarding state. The alternative port will surely belong to Switch4.

  Switch4 will need to block one of its ports to avoid a bridging loop between the two switches. But how does Switch4 select its blocked port? Well, the answer is based on the BPDUs it receives from Switch3. A BPDU is superior to another if it has:

  1.

  A lower Root Bridge ID

  2.

  A lower path cost to the Root

  3.

  A lower Sending Bridge ID

  4.

  A lower Sending Port ID

  These four parameters are examined in order. In this specific case, all the BPDUs sent by Switch3 have the same Root Bridge ID, the same path cost to the Root and the same Sending Bridge ID. The only parameter left to select the best one is the Sending Port ID (Port ID = port priority + port index). In this case the port priorities are equal because they use the default value, so Switch4 will compare port index values, which are unique to each port on the switch, and because Fa0/12 is inferior to Fa0/1, Switch4 will select the port connected with Fa0/1 (of Switch3) as its root port and block the other port -> Port fa0/11 of Switch4 will be blocked (discarding role).

• Question 579:

  

  Refer to the exhibit. Which command would you use to configure a static route on Router1 to network 192.168.202.0/24 with a nondefault administrative distance?

  A. router1(config)#ip route 192.168.202.0 255.255.255.0 192.168.201.2 1
  B. router1(config)#ip route 192.168.202.0 255.255.255.0 192.168.201.2 5
  C. router1(config)#ip route 1 192.168.201.1 255.255.255.0 192.168.201.2
  D. router1(config)#ip route 5 192.168.202.0 255.255.255.0 192.168.201.2
  B. router1(config)#ip route 192.168.202.0 255.255.255.0 192.168.201.2 5
