Cisco discovery drs ent module 3 - v.4 in english.

  1. 1. Cisco Discovery - DRSEnt Module 3 - V.4 in english.Q.1 Refer to the exhibit. What two statements can be concluded from the information that is shown inthe exhibit? (Choose two.) All ports that are listed in the exhibit are access ports. ARP requests from Host1 will be forwarded to Host2. Attaching Host1 to port 3 will automatically allow communication between both hosts. The default gateway for each host must be changed to to allow communicationbetween both hosts. A router connected to the switch is needed to forward traffic between the hosts.Q.2 A router is configured to connect to a trunked uplink as shown in the exhibit. A packet is received onthe FastEthernet 0/1 physical interface from VLAN 10. The packet destination address is will the router do with this packet? The router will forward the packet out interface FastEthernet 0/1.1 tagged for VLAN 10. The router will forward the packet out interface FastEthernet 0/1.2 tagged for VLAN 60. The router will forward the packet out interface FastEthernet 0/1.3 tagged for VLAN 60. The router will forward the packet out interface FastEthernet 0/1.3 tagged for VLAN 120. The router will not process the packet since the source and destination are on the same subnet. The router will drop the packet since no network that includes the source address is attached to therouter.Q.3 The information contained in a BPDU is used for which two purposes? (Choose two.) to prevent loops by sharing bridging tables between connected switches to set the duplex mode of a redundant link to determine the shortest path to the root bridge to determine which ports will forward frames as part of the spanning tree
  2. 2. to activate looped paths throughout the networkQ.4 A router has two serial interfaces and two Fast Ethernet interfaces. This router must be connectedto a WAN link and to a switch that supports four VLANs. How can this be accomplished in the mostefficient and cost-effective manner to support inter-VLAN routing between the four VLANs? Connect a smaller router to the serial interface to handle the inter-VLAN traffic. Add two additional Fast Ethernet interfaces to the router to allow one VLAN per interface. Connect a trunked uplink from the switch to one Fast Ethernet interface on the router and createlogical subinterfaces for each VLAN. Use serial-to-Fast Ethernet transceivers to connect two of the VLANs to the serial ports on therouter. Support the other two VLANs directly to the available FastEthernet ports.Q.5 When are MAC addresses removed from the CAM table? at regular 30 second intervals when a broadcast packet is received when the IP Address of a host is changed after they have been idle for a certain period of timeQ.6 Refer to the exhibit. Switch1 is not participating in the VTP management process with the otherswitches. Which two are possible reasons for this? (Choose two.) Switch2 is in transparent mode. Switch1 is in client mode. Switch1 is using VTP version 1 and Switch2 is using VTP version 2. Switch2 is in server mode. Switch1 is in a different management domain. Switch1 has no VLANs.
  3. 3. Q.7 Which three must be used when a router interface is configured for VLAN trunking? (Choose three.) one subinterface per VLAN one physical interface for each subinterface one IP network or subnetwork for each subinterface one trunked link per VLAN a management domain for each subinterface a compatible trunking protocol encapsulation for each subinterfaceQ.8 Refer to the exhibit. The switches are connected with trunks within the same VTP managementdomain. Each switch is labeled with its VTP mode. A new VLAN is added to Switch3. This VLAN does notshow up on the other switches. What is the reason for this? VLANs cannot be created on transparent mode switches. Server mode switches neither listen to nor forward VTP messages from transparent mode switches. VLANs created on transparent mode switches are not included in VTP advertisements. There are no ports assigned to the new VLAN on the other switches. Transparent mode switches do not forward VTP advertisements.Q.9 Which two criteria are used by STP to select a root bridge? (Choose two.) memory size bridge priority switching speed number of ports base MAC address switch locationQ.10 Which three steps should be taken before moving a Catalyst switch to a new VTP managementdomain? (Choose three.)
  4. 4. Reboot the switch. Reset the VTP counters to allow the switch to synchronize with the other switches in the domain. Download the VTP database from the VTP server in the new domain. Configure the VTP server in the domain to recognize the BID of the new switch. Select the correct VTP mode and version. Configure the switch with the name of the new management domain.Q.11 Which two items will prevent broadcasts from being sent throughout the network? (Choose two.) bridges routers switches VLANs hubsQ.12 Which two characteristics describe a port in the STP blocking state? (Choose two.) provides port security displays a steady green light learns MAC addresses as BPDUs are processed discards data frames received from the attached segment receives BPDUs and directs them to the system moduleQ.13 What is the first step in the process of convergence in a spanning tree topology? election of the root bridge determination of the designated port for each segment blocking of the non-designated ports
  5. 5. selection of the designated trunk port activation of the root port for each segmentQ.14 In which STP state does a switch port transmit user data and learn MAC addresses? blocking learning disabling listening forwardingQ.15 What is the purpose of VTP? maintaining consistency in VLAN configuration across the network routing frames from one VLAN to another routing the frames along the best path between switches tagging user data frames with VLAN membership information distributing BPDUs to maintain loop-free switched pathsQ.16 Which statement best describes adaptive cut-through switching? The switch initially forwards all traffic using cut-through switching and then changes to store-and-forward switching if errors exceed a threshold value. The switch initially forwards all traffic using cut-through switching and then changes to fast-forwardswitching if errors exceed a threshold value. The switch initially forwards all traffic using cut-through switching and then temporarily disables theport if errors exceed a threshold value. The switch initially forwards all traffic using store-and-forward switching and then changes to cut-through switching if errors exceed a threshold value.
  6. 6. Q.17 Using STP, how long does it take for a switch port to go from the blocking state to the forwardingstate? 2 seconds 15 seconds 20 seconds 50 secondsQ.18 Refer to the exhibit. The switches are interconnected by trunked links and are configured for VTPas shown. A new VLAN is added to Switch1. Which three actions will occur? (Choose three.) Switch1 will not add the VLAN to its database and will pass the update to Switch 2. Switch2 will add the VLAN to its database and pass the update to Switch3. Switch3 will pass the VTP update to Switch4. Switch3 will add the VLAN to its database. Switch4 will add the VLAN to its database. Switch4 will not receive the update.Q.19 Which Catalyst feature causes a switch port to enter the spanning-tree forwarding stateimmediately? backbonefast uplinkfast portfast rapid spanning treeQ.20 Refer to the exhibit. Which set of commands would be used on the router to providecommunication between the two hosts connected to the switch? Router(config)# interface vlan 2 Router(config-if)# ip address
