B. the switch type. Reference: http://www. No configuration must be added. the switch stack accepts the configuration. 4 5 8 9 10 13 Correct Answer: D Section: Layer 2 Technologies Explanation Explanation/Reference: Explanation: Up to 9 Cisco Catalyst switches can be stacked together to build single logical StackWise switch since Cisco IOS XE Release 3. The interface associated with the provisioned switch does not appear in the display of the specific feature. F. When you configure the interfaces associated with a provisioned switch (for example. Which configuration must be added to the new switch before it can be added to the switch stack? A. stack ID IP address VLAN information VTP information Correct Answer: A Section: Layer 2 Technologies Explanation Explanation/Reference: Explanation: Switch Stack Offline Configuration You can use the offline configuration feature to provision (to supply a configuration to) a new switch before it joins the switch stack. E. and the no shutdown interface configuration command does not return it to active service. You can configure in advance the stack member number. D. The switch that is added to the switch stack and that receives this configuration is called the provisioned switch .3.300-115 QUESTION 1 What is the maximum number of switches that can be stacked using Cisco StackWise? A.switches/qa_c67722110. B. Prior to Cisco IOS XE Release3. You manually create the provisioned configuration through the switch stack-member-number provision type global configuration command. The provisioned configuration is automatically created when a switch is added to a switch stack and when no provisioned configuration exists.

A break in any one of the cables will result in the stack bandwidth being reduced to half of its full capacity. Cisco StackWise Technology Resilient Cabling . 0 25 50 75 100 Correct Answer: C Section: Layer 2 Technologies Explanation Explanation/Reference: Explanation: Physical Sequential Linkage The switches are physically connected sequentially.

Which set of configurations will result in all ports on both switches successfully bundling into an EtherChannel?

A monitor session on the distribution switch with a physical interface as the source and the remote SPAN VLAN as the destination . An interface in the auto mode cannot form an EtherChannel with another interface that is also in the auto mode because neither interface starts PAgP negotiation. but does not start LACP packet negotiation. A network engineer wants to analyze all incoming and outgoing packets for an interface that is connected to an access switch. An interface in the on mode that is added to a port channel is forced to have the same characteristics as the already existing on mode interfaces in the channel. For example: ·An interface in the desirable mode can form an EtherChannel with another interface that is in the desirable or auto mode. Reference: http://www.html QUESTION 5 Refer to the exhibit. desirable Places an interface into an active negotiating state. for Layer 2 EtherChannels. With the on mode. passive Places an interface into a passive negotiating state. in which the interface responds to LACP packets that it receives. on Forces the interface into an EtherChannel without PAgP or LACP. in which the interface starts negotiations with other interfaces by sending PAgP packets.active Places an interface into an active negotiating state. auto Places an interface into a passive negotiating state.1_13_ea1/ configuration/guide/3550scg/swethchl. Interfaces can form an EtherChannel when they are in different PAgP modes as long as the modes are compatible. This setting minimizes the transmission of LACP packets. Which three items must be configured to mirror traffic to a packet sniffer that is connected to the distribution switch? (Choose three. This setting minimizes the transmission of PAgP packets. Both the auto and desirable PAgP modes allow interfaces to negotiate with partner interfaces to determine if they can form an EtherChannel based on criteria such as interface speed and.ation.com/c/en/us/td/docs/switches/lan/catalyst3550/software/release/12.) A. a usable EtherChannel exists only when an interface group in the on mode is connected to another interface group in the on mode. ·An interface in the auto mode can form an EtherChannel with another interface in the desirable mode. in which the interface responds to PAgP packets it receives but does not start PAgP packet negoti. trunking state and VLAN numbers.cisco. in which the interface starts negotiations with other interfaces by sending LACP packets.

The traffic for each RSPAN session is carried over a user-specified RSPAN VLAN that is dedicated for that RSPAN session in all participating switches. A remote SPAN VLAN on the distribution and access layer switch C. and destination ports on different switches (or different switch stacks). RSPAN supports source ports.2_55_se/ configuration/guide/3750xscg/swspan.B. A monitor session on the distribution switch with a physical interface as the source and a physical interface as the destination Correct Answer: BCD Section: Layer 2 Technologies Explanation Explanation/Reference: Explanation: You can analyze network traffic passing through ports or VLANs by using SPAN or RSPAN to send a copy of the traffic to another port on the switch or on another switch that has been connected to a network analyzer or other monitoring or security device. SPAN copies (or mirrors) traffic received or sent (or both) on source ports or source VLANs to a destination port for analysis.com/c/en/us/td/docs/switches/lan/catalyst3750x_3560x/software/release/12. A monitor session on the access switch with a physical interface source and the remote SPAN VLAN as the destination D. Each RSPAN source switch must have either ports or VLANs as RSPAN sources. The destination is always a physical port Reference: http://www. A monitor session on the access switch with a remote SPAN VLAN source and the physical interface as the destination F. The RSPAN traffic from the source ports or VLANs is copied into the RSPAN VLAN and forwarded over trunk ports carrying the RSPAN VLAN to a destination session monitoring the RSPAN VLAN.html . enabling remote monitoring of multiple switches across your network.
