Cisco 200-105 Online Questions & Answers

• Question 31:

  Which result occurs when you configure the switchport mode dynamic auto command on the switch ports at both ends of a trunk link?

  A. The trunk forms immediately because both switch ports are configured for permanent trunking mode
  B. Either switch port can initiate the trunk
  C. Both switch ports actively form the trunk
  D. The trunk fails to form because both switch ports fail to initiate trunking
  D. The trunk fails to form because both switch ports fail to initiate trunking

• Question 32:

  Which troubleshooting tool can you use to replicate traffic within a single switch for analysis?

  A. RSPAN
  B. EEM
  C. local SPAN
  D. ERSPAN
  C. local SPAN

• Question 33:

  Refer to the exhibit. Which two statements are true about the loopback address that is configured on RouterB? (Choose two.)

  

  A. It ensures that data will be forwarded by RouterB.
  B. It provides stability for the OSPF process on RouterB.
  C. It specifies that the router ID for RouterB should be 10.0.0.1.
  D. It decreases the metric for routes that are advertised from RouterB.
  E. It indicates that RouterB should be elected the DR for the LAN.
  B. It provides stability for the OSPF process on RouterB.
  C. It specifies that the router ID for RouterB should be 10.0.0.1.

  A loopback interface never comes down even if the link is broken so it provides stability for the OSPF process (for example we use that loopback interface as the router-id) -B is correct.

  The router-ID is chosen in the order below:

  The highest IP address assigned to a loopback (logical) interface. If a loopback interface is not defined, the highest IP address of all active router's physical interfaces will be chosen. The loopback interface will be chosen as the router ID of

  RouterB-C is correct.

• Question 34:

  Refer to the exhibit.

  What three actions will the switch take when a frame with an unknown source MAC address arrives at the interface? (Choose three.)

  

  A. Send an SNMP trap.
  B. Send a syslog message.
  C. Increment the Security Violation counter.
  D. Forward the traffic.
  E. Write the MAC address to the startup-config.
  F. Shut down the port.
  A. Send an SNMP trap.
  B. Send a syslog message.
  C. Increment the Security Violation counter.

  Switchport Security Concepts and Configuration

  The second piece of switchport port-security that must be understood is a security violation including what it is what causes it and what the different violation modes that exist. A switchport violation occurs in one of two situations:

  When the maximum number of secure MAC addresses has been reached (by default, the maximum number of secure MAC addresses per switchport is limited to 1).

  An address learned or configured on one secure interface is seen on another secure interface in the same VLAN.

  The action that the device takes when one of these violations occurs can be configured:

  Protect--This mode permits traffic from known MAC addresses to continue to be forwarded while dropping traffic from unknown MAC addresses when over the allowed MAC address limit. When configured with this mode, no notification action

  is taken when traffic is dropped.

  Restrict--This mode permits traffic from known MAC addresses to continue to be forwarded while dropping traffic from unknown MAC addresses when over the allowed MAC address limit. When configured with this mode, a syslog message is

  logged, a Simple Network Management Protocol (SNMP) trap is sent, and a violation counter is incremented when traffic is dropped. Shutdown--This mode is the default violation mode; when in this mode, the switch will automatically force

  the switchport into an error disabled (err-disable) state when a violation occurs. While in this state, the switchport forwards no traffic. The switchport can be brought out of this error disabled state by issuing the errdisable recovery cause CLI

  command or by disabling and re-enabling the switchport. Shutdown VLAN--This mode mimics the behavior of the shutdown mode but limits the error disabled state the specific violating VLAN.

• Question 36:

  Refer to the exhibit. What is the cause of the Syslog output messages?

  

  A. The EIGRP neighbor on Fa0/1 went down due to a failed link.
  B. The EIGRP neighbor connected to Fa0/1 is participating in a different EIGRP process, causing the adjacency to go down.
  C. A shut command was executed on interface Fa0/1, causing the EIGRP adjacency to go down.
  D. Interface Fa0/1 has become error disabled, causing the EIGRP adjacency to go down.
  C. A shut command was executed on interface Fa0/1, causing the EIGRP adjacency to go down.
