- 1 *
- 3
- 2c
10. A network administrator has received complaints about slow network performance on one segment of a Layer 2 switched network. To determine what types of traffic are on the segment, the administrator decides to configure SPAN to allow the installation of a packet sniffer. Which two items must be configured to allow SPAN to function? (Choose two.)
- the port that connects to the packet sniffer *
- the threshold value of monitored traffic
- the dot1q encapsulation on the monitored port
- a monitored port or VLAN *
- the sampling rate of the monitored port or VLAN
11. In the configuring of RSPAN, what is true of the RSPAN VLAN?
- The RSPAN VLAN can be used for remote management of network switches.
- The RSPAN VLAN must be the same on both the source and destination switch.*
- The RSPAN VLAN can be used to carry secure traffic between switches.
- The RSPAN VLAN must be the same as the native VLAN.
12. Refer to the exhibit. The RSPAN configuration for each switch is shown. The network administrator has configured RSPAN to allow the monitoring of traffic to a corporate server. Unfortunately, the administrator is unable to sniff any traffic from the link. Why is the administrator unable to sniff traffic?
- The session numbers on the two switches do not match.
- The remote interface on SW1 should be identified as fa0/3.
- VLAN 100 has not been properly configured as an RSPAN VLAN.*
- The source and destination interfaces are reversed on SW2.
- Only VLAN 1 can be used as the RSPAN VLAN.
13. What can cause a memory leak on a router?
- incorrect configuration registry code
- buffer overflow
- an IOS bug *
- too many remote users logged into the router
14. Refer to the exhibit. A network administrator is configuring NetFlow on the HQ router and enters the commands that are shown. What is the significance of the number “9991” in the commands that are entered?
- This is the value the network administrator has assigned to identify the monitored flow.
- This is the flow number that NetFlow will export to the destination IP.
- This is the UDP port that will be used to export information to the destination IP.*
- This is the number of seconds for which the identified flow should be monitored before exporting information to the destination IP.
- This is the maximum number of flows that will be monitored by this instance of NetFlow.
15. Refer to the exhibit. What tool was used to generate the output that is displayed?
- SNMP
- SPAN
- syslog
- RSPAN
- NetFlow *
16. Refer to the exhibit. The administrative assistant using the user PC complains that retrieving email has been slow for the past 30 minutes. The network administrator using the administrative PC sees the same results. In an effort to identify the exact problem area, the network administrator accesses the IT services server to retrieve performance data from the SQL server about the mail server. Which device in this scenario is considered an SNMP NMS?
- IT services server *
- administrative PC
- mail server
- user PC
- SQL server
17. A network administrator has noticed an unusual amount of traffic being received on a switch port that is connected to a college classroom computer. Which tool would the administrator use from the NOC to take a closer look at the type of traffic that is being sent to the PC?
