• Question 312:

  What command visualizes the general NetFlow data on the command line?

  A. show ip flow export
  B. show ip flow top-talkers
  C. show ip cache flow
  D. show mls sampling
  E. show mls netflow ip
  C. show ip cache flow

  ---

  The following is an example of how to visualize the NetFlow data using the CLI. There are three methods to visualize the data depending on the version of Cisco IOS Software. The traditional show command for NetFlow is "show ip cache flow" also available are two forms of top talker commands. One of the top talkers' commands uses a static configuration to view top talkers in the network and another command called dynamic top talkers allows real-time sorting and aggregation of NetFlow data. Also shown is a show MLS command to view the hardware cache on the Cisco Catalyst 6500 Series Switch. The following is the original NetFlow show command used for many years in Cisco IOS Software. Information provided includes packet size distribution; basic statistics about number of flows and export timer setting, a view of the protocol distribution statistics and the NetFlow cache.

• Question 313:

  Refer to the exhibit.

  Given the output from the show ip eigrp topology command, which router is the feasible successor?

  

  B. C. D.
  B. C. D.

  ---

  To be the feasible successor, the Advertised Distance (AD) of that route must be less than the Feasible Distance (FD) of the successor. From the output of the "show ip eigrp topology 10.0.0.5 255.255.255.255 we learn that the FD of the

  successor is 41152000.

  Now we will mention about the answers, in the "Composite metric is (.../...)" statement the first parameter is the FD while the second parameter is the AD of that route. So we need to find out which route has the second parameter (AD) less

  than 41152000 -> only answer B satisfies this requirement with an AD of 128256.

• Question 314:

  What are three benefits of implementing VLANs? (Choose three.)

  A. A higher level of network security can be reached by separating sensitive data traffic from other network traffic.
  B. A more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure.
  C. A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.
  D. Broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size
  E. Broadcast storms can be mitigated by decreasing the number of broadcast domains, thus increasing their size.
  F. VLANs make it easier for IT staff to configure new logical groups, because the VLANs all belong to the same broadcast domain.
  G. Port-based VLANs increase switch-port use efficiency, thanks to 802.1Q trunks.

  Understanding VLAN Trunk Protocol (VTP)

  Introduction

  VLAN Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN

  everywhere. VTP is a Cisco-proprietary protocol that is available on most of the Cisco Catalyst series products.

• Question 319:

  Which of the following is needed to be enable back the role of active in HSRP?

  A. prempt
  B. priority
  C. cost
  D. failover
  A. prempt

• Question 320:

  Refer to the exhibit.

  If the router Cisco returns the given output and has not had its router ID set manually, what value will OSPF use as its router ID?

  

  A. 192.168.1.1
  B. 172.16.1.1
  C. 1.1.1.1
  D. 2.2.2.2
  D. 2.2.2.2

  ---

  If a router-id is not configured manually in the OSPF routing process the router will automatically configure a router-id determined from the highest IP address of a logical interface (loopback interface) or the highest IP address of an active interface. If more than one loopback interfaces are configured, the router will compare the IP addresses of each of the interfaces and choose the highest IP address from the loopbacks.
