  F. The switch drops broadcasts when they reach 75% of bandwidth.
  C. The switch resumes forwarding broadcasts when they are below 65% of bandwidth.
  D. Only broadcast traffic is limited by this particular storm control configuration.
  F. The switch drops broadcasts when they reach 75% of bandwidth.

  storm-control {broad- Configure broadcast, multicast, or unicast storm control. By de- cast | multicast | uni- fault, storm control is disabled.

  cast} level {level [lev-

  The keywords have these meanings:

  el-low] | pps pps [pps-low]}

  For level, specify the rising threshold level for broadcast, multicast, or unicast traffic as a percentage (up to two decimal places) of the bandwidth. The port blocks traffic when the rising threshold is reached. The range is 0.00 to 100.00.

  (Optional) For level-low, specify the falling threshold level as a percentage (up to two decimal places) of the bandwidth. This value must be less than or equal to the rising suppression value. The port forwards traffic when traffic drops below

  this level. If you do not configure a falling suppression level, it is set to the rising suppression level. The range is 0.00 to 100.00.

  In this case, the broadcast keyword was used so only broadcast traffic is limited. Reference: http:// www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3550/ software/release/12- 2_25_see/configuration/ guide/3550SCG/swtrafc.html

• Question 424:

  Which two statements about the monitored traffic in a SPAN session are true? (Choose two.)

  A. You cannot configure two separate SPAN or RSPAN source sessions with separate or overlapping sets of SPAN source ports and VLANs
  B. By default, all monitored packets are captured without the IEEE 802.1Q tag
  C. Egress SPAN monitors packets sent by the source interface before any QoS modifcations
  D. Sources can be ports or VLANs or any combination in the same session
  E. By default, all monitored packets include the IEEE 802.1Q tag that they had on the source port
  F. Ingress SPAN monitors packets received by the source interface before any QoS modifications
  C. Egress SPAN monitors packets sent by the source interface before any QoS modifcations
  D. Sources can be ports or VLANs or any combination in the same session

• Question 425:

  Question about what does MST do? (Question looks incomplete)

  A. disable RSTP and uses bpdu type 4
  B. enable RSTP and uses bpdu type 4
  C. disable RSTP and uses bpdu type 2
  D. enable RSTP and uses bpdu type 2
  D. enable RSTP and uses bpdu type 2

• Question 426:

  A question about how SPAN will react to EtherChannel?

  A. Source port will be monitored.
  B. Destination port will be excluded while the monitor session is active.
  C. http://certbus.com
  D. http://certbus.com
  A. Source port will be monitored.

• Question 427:

  What percentage of bandwidth is reduced when a stack cable is broken?

  B. 25
  C. 50
  D. 75
  E. 100
  C. 50

  ---

  Physical Sequential Linkage The switches are physically connected sequentially, as shown in Figure 3. A break in any one of the cables will result in the stack bandwidth being reduced to half of its full capacity. Subsecond timing mechanisms detect traffic problems and immediately institute failover. This mechanism restores dual path flow when the timing mechanisms detect renewed activity on the cable. Figure 3. Cisco StackWise Technology Resilient Cabling

• Question 428:

  Which virtual MAC address does HSRP group 37 use with default configuration?

  A. C0.00:00:255:00:00
  B. 00:00:0c:07:ac:25
  C. C0:00:00:37:00:00
  D. 00:00:00c:07:ac:37
  B. 00:00:0c:07:ac:25

• Question 429:

  Refer to the exhibit.

  

  When a network administrator is attempting an SSH connection to the device, in which order does the device check the login credentials?

  A. RADIUS server, local username, line password
  B. RADIUS server, line password, local username
  C. Line password, local username, RADIUS server
  D. Line password, RADIUS server, local username
  A. RADIUS server, local username, line password

  ---

  SSH sessions use the vty lines, where the configured authentication method is named "default." The AAA default login preference is stated in order from first to last, so here the "aaa authentication login default group radius local line" means to use RADIUS first, then if that fails use the local user database. Finally, if that fails use the line password.

• Question 430:

  What is the default HSRP priority?

  A. 50
  B. 100
  C. 120
  D. 1024
  B. 100

  ---

  standby [group-num- Set a priority value used in choosing the active router. The ber] priority priority range is 1 to 255; the default priority is 100. The highest [preempt [delay delay]] number represents the highest priority.

  (Optional) group-number--The group number to which

  the command applies.

  (Optional)

  preempt--Select so that when the local router has a higher priority than the active router, it assumes control as the active router.

  (Optional)

  delay--Set to cause the local router to post- pone taking over the active role for the shown number of sec- onds. The range is 0 to 36000 (1 hour); the default is 0 (no de- lay before taking over). Use the no form of the command to restore the

  default values.
