Cisco 300-410 Online Questions & Answers

• Question 241:

  Refer to the exhibit.

  

  A network administrator must block ping from user 3 to the App Server only. An inbound standard access list is applied to R1 interface G0/0 to block ping. The network administrator was notified that user 3 cannot even ping user 9 anymore. Where must the access list be applied in the outgoing direction to resolve the issue?

  A. R2 interface G1/0
  B. R2 interface G0/0
  C. SW1 interface G1/10
  D. SW1 interface G2/21
  C. SW1 interface G1/10

• Question 242:

  What does the passive-interface command do when implement with RIP? (Choose two.)

  A. Allows an interface to receive routing update traffic
  B. Prevents an interface from sending routing update traffic
  C. Prevents an interface from sending any normal data traffic
  D. Allows an interface to receive normal data traffic
  E. Disables a router interface
  F. Places a router interface in standby mode
  A. Allows an interface to receive routing update traffic
  B. Prevents an interface from sending routing update traffic

  ---

  The effect of the passive-interface command is dependent on the routing protocol running on the interface. For EIGRP, the router will not only stop sending routing updates, but also hellos, which means that it will not form a neighbor relationship with another EIGRP router on that interface. This is also the case with OSPF and IS-IS. With RIP, however, the router will continue to send hellos even as it stops sending routing updates, and it will still receive routing updates. An example of using the passive-interface command is below. The command is issued from the router configuration mode.

  Router(config-router)# passive-interface ethernet 0/0

  The passive-interface command will even overrule a configuration that includes a distribute list that allows the advertisement of a network through the interface. Examine the partial output of the show run command taken from a router running EIGRP below: router6#show run ! router eigrp 100 network 10.16.18.0 0.0.255.255

  network 10.16.19.0 0.0.255.255

  passive-interface serial 0/0

  distribute-list 50 out serial 0/0

  !

  Access-list 50 permit 10.16.8.0 0.0.255.255

  In this case, although the distribute list allows the advertisement of the 10.16.8.0 network, the passive- interface command applied to the Serial 0/0 interface will disallow all outgoing and incoming updates.

  The passive-interface command does not affect the transmission or reception of normal data traffic, only routing updates.

  The passive-interface command does not disable the router interface. The shutdown command is used to disable a router interface.

  The passive-interface command does not place the router in standby mode.

• Question 243:

  Consider the following commands:

  RouterA(config)# router ospf 10 RouterA(config-router)# redistribute eigrp 20 metric 30 What does the value of 30 represent?

  A. It identifies the seed metric associated with OSPF routes that are redistributed into EIGRP.
  B. It identifies the seed metric associated with EIGRP routes that are redistributed into OSPF.
  C. It identifies the amount that the existing EIGRP metric will increment as it is redistributed into OSPF.
  D. It specifies that routes that contain metrics of less than 30 will be redistributed from OSPF into EIGRP.
  B. It identifies the seed metric associated with EIGRP routes that are redistributed into OSPF.

  ---

  The value 30 represents the seed metric for routes that are redistributed from EIGRP into OSPF.

  When configuring the OSPF process, the redistribute command is used to identify the source protocol, its AS or process ID, and several other optional parameters, such as metric. The default seed metric for all routing protocols except BGP is

  20. When redistributing BGP, the default seed metric is 1.

  It does not identify the seed metric associated with OSPF routes that are redistributed into EIGRP. The command is redistributing EIGRP into OSPF, not OSPF into EIGRP.

  It does not identify the amount that the existing EIGRP metric will increment as it is redistributed into OSPF. A seed metric value is an absolute value not incremental.

  It does not specify that routes that contain metrics of less than 30 will be redistributed from OSPF into EIGRP. It not used to filter routes.

• Question 244:

  A network engineer needs to verify IP SLA operations on an interface that shows on indication of excessive traffic. Which command should the engineer use to complete this action?

  A. show frequency
  B. show track
  C. show reachability
  D. show threshold
  B. show track

• Question 245:

  Which configuration on the hub router meets this requirement?

  A. interface Tunnel0 tunnel mode gre multipoint
  B. interface Tunnel0 tunnel mode dvmrp
  C. interface Tunnel0 tunnel mode ipsec ipv4
  D. interface Tunnel0 tunnel mode ip
  A. interface Tunnel0 tunnel mode gre multipoint

• Question 246:

  Refer to the exhibit. An engineer is trying to generate a summary route in OSPF for network 10.0.0.0/8, but the summary route does not show up in the routing table. Why is the summary route missing?

  

  A. The summary-address command is used only for summarizing prefixes between areas.
  B. The summary route is visible only in the OSPF database, not in the routing table.
  C. There is no route for a subnet inside 10.0.0.0/8, so the summary route is not generated.
  D. The summary route is not visible on this router, but it is visible on other OSPF routers in the same area.
  C. There is no route for a subnet inside 10.0.0.0/8, so the summary route is not generated.

  ---

  The summary-address is only used to create aggregate addresses for OSPF at an autonomous system boundary.

  It means this command should only be used on the ASBR when you are trying to summarize externally redistributed routes from another protocol domain or you have a NSSA area. But a requirement to create a summarized route is:

  The ASBR compares the summary route's range of addresses with all routes redistributed into OSPF on that ASBR to find any subordinate subnets (subnets that sit inside the summary route range). If at least one subordinate subnet exists, the ASBR advertises the summary route.

• Question 247:

  The network administrator configured the router for Control Plane Policing to limit OSPF traffic to be policed to 1 Mbps. Any traffic that exceeds this limit must also be allowed at this point for traffic analysis. The router configuration is:

  access-list 100 permit ospf any any ! class-map CM-OSPF match access-group 100 ! policy-map PM-COPP class CM-OSPF police 1000000 conform-action transmit ! control-plane service-policy output PM-COPP

  The Control Plane Policing failed to monitor and police OSPF traffic. Which configuration resolves this issue?

  A. policy-map PM-COPP class CM-OSPF no police 1000000 conform-action transmit police 1000000 conform-action transmit exceed-action transmit ! control-plane no service-policy output PM-COPP
  B. policy-map PM-COPP class CM-OSPF no police 1000000 conform-action transmit police 1000000 conform-action transmit exceed-action transmit
  C. control-plane no service-policy output PM-COPP service-policy input PM-COPP
  D. no access-list 100 access-list 100 deny ospf any any access-list 100 permit ip any any ! policy-map PM-COPP class CM-OSPF no police 1000000 conform-action transmit police 1000000 conform-action transmit exceed-action drop ! control-plane no service-policy output PM-COPP service-policy input PM-COPP
  C. control-plane no service-policy output PM-COPP service-policy input PM-COPP

• Question 248:

  Refer to the exhibit. An engineer cannot copy the IOS.bin file from the FTP server to the switch.

  

  Which action resolves the issue?

  A. Allow file permissions to download the file from the FTP server.
  B. Add the IOS.bin file, which does not exist on FTP server.
  C. Make memory space on the switch flash or USB drive to download the file.
  D. Use the copy flash:/ ftp://[email protected]/IOS.bin command.
  B. Add the IOS.bin file, which does not exist on FTP server.

• Question 249:

  Refer to the exhibit.

  

  

  

  An engineer troubleshoots a connectivity problem that is impacting the communication from the users at segment 172.16.3.16 /28 to the server farm at 192.168.5.16/

  28. Which configuration resolves the issue on router R1?

  A. router rip redistribute ospf 1 metric 16
  B. router ospf 1 redistribute rip metric 14
  C. router rip redistribute ospf 1 metric 14
  D. router ospf 1 redistribute rip metric 16
  C. router rip redistribute ospf 1 metric 14

• Question 250:

  Refer to the exhibit.

  

  The remote server is failing to receive the NetFlow data. Which action resolves the issue?

  A. Modify the flow transport command transport udp 2055 to move under flow monitor profile.
  B. Modify the interface command to ip flow monitor FLOW-MONITOR-1 input.
  C. Modify the udp port under flow exporter profile to ip transport udp 4739.
  D. Modify the flow record command record v4_r1 to move under flow exporter profile.
  B. Modify the interface command to ip flow monitor FLOW-MONITOR-1 input.

  ---

  From the exhibit we see there are two flow monitors: the first one "FLOW-MONITOR-1" has been configured correctly but the second one "v4_r1" was left empty andinterface E0/0.1 is using it. So the remote server does not receive any NetFlow data.
