  NetFlow facilitates solutions to many common problems encountered by IT professionals.

  +

  Analyze new applications and their network impact

  Identify new application network loads such as VoIP or remote site additions.

  +

  Reduction in peak WAN traffic

  Use NetFlow statistics to measure WAN traffic improvement from application-policy changes;

  understand who is utilizing the network and the network top talkers.

  +

  Troubleshooting and understanding network pain points

  Diagnose slow network performance, bandwidth hogs and bandwidth utilization quickly with command line interface or reporting tools.

  +

  Detection of unauthorized WAN traffic

  Avoid costly upgrades by identifying the applications causing congestion.

  +

  Security and anomaly detection

  NetFlow can be used for anomaly detection and worm diagnosis along with applications such as Cisco CS-Mars.

  +

  Validation of QoS parameters

  Confirm that appropriate bandwidth has been allocated to each Class of Service (CoS) and that no CoS is over-or under-subscribed.

  A. The router becomes the active router only when the current active router fails
  B. The router fails to become the active router under any circumstances
  C. The router immediately becomes the active router because it has the highest configured IP address
  D. The router becomes the active router only when another router triggers renegotiation of the active router
  A. The router becomes the active router only when the current active router fails

  ---

  A standby router with equal priority but a higher IP address will not preempt the active router Reference: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipapp_fhrp/configuration/15-sy/fhp-15-sy-book/fhp-hsrp.pdf

• Question 629:

  CORRECT TEXT Lab - Access List Simulation A network associate is adding security to the configuration of the Corp1 router. The user on host C should be able to use a web browser to access financial information from the Finance Web Server. No other hosts from the LAN nor the Core

  should be able to use a web browser to access this server. Since there are multiple resources for the corporation at this location including other resources on the Finance Web Server, all other traffic should be allowed.

  The task is to create and apply a numbered access-list with no more than three statements that will allow ONLY host C web access to the Finance Web Server. No other hosts will have web access to the Finance Web Server. All other traffic

  is permitted. Access to the router CLI can be gained by clicking on the appropriate host.

  All passwords have been temporarily set to "cisco".

  The Core connection uses an IP address of 198.18.196.65

  The computers in the Hosts LAN have been assigned addresses of 192.168.33.1 ?92.168.33.254

  Host A 192.168.33.1

  Host B 192.168.33.2

  Host C 192.168.33.3

  Host D 192.168.33.4

  The servers in the Server LAN have been assigned addresses of 172.22.242.17 ?172.22.242.30

  The Finance Web Server is assigned an IP address of 172.22.242.23.

  The Public Web Server is assigned an IP address of 172.22.242.17

  

  Correct Answer. Check the answer below
  Check the answer below

  Corp1#configure terminal

  Our access-list needs to allow host C ?192.168.33.3 to the Finance Web Server 172.22.242.23 via web (port 80) Corp1(config)#access-list 100 permit tcp host 192.168.33.3 host 172.22.242.23 eq 80 Deny other hosts access to the Finance Web Server via web Corp1(config)#access-list 100 deny tcp any host 172.22.242.23 eq 80 All other traffic is permitted

  Corp1(config)#access-list 100 permit ip any any

  Apply this access-list to Fa0/1 interface (outbound direction)

  Corp1(config)#interface fa0/1Corp1(config-if)#ip access-group 100 out

  Select the console on Corp1 router

  Configuring ACLCorp1>enableCorp1#configure terminal

  Comment: To permit only Host C (192. 168. 33. 3){source addr} to access finance server address (172.22.242. 23){destination addr} on port number 80 (web) Corp1(config)# access-list 100 permit tcp host 192.168.33.3 host 172.22.242.23 eq 80 Comment: To deny any source to access finance server address (172. 22. 242. 23) {destination addr} on port number 80 (web)

  Corp1(config)# access-list 100 deny tcp any host 172.22.242.23 eq 80

  Comment: To permit ip protocol from any source to access any destination because of the implicit deny any any statement at the end of ACL. Corp1(config)# access-list 100 permit ip any any Applying the ACL on the Interface Comment: Check show ip interface brief command to identify the interface type and number by checking the IP address configured.

  Corp1(config)#interface fa 0/1

  If the ip address configured already is incorrect as well as the subnet mask. this should be corrected in order ACL to work type this commands at interface mode :

  no ip address 192. x. x. x 255. x. x. x (removes incorrect configured ip address and subnet mask) Configure Correct IP Address and subnet mask :

  ip address 172. 22. 242. 30 255. 255. 255. 240 ( range of address specified going to server is given as 172.22. 242. 17 172. 22. 242. 30 )

  Comment: Place the ACL to check for packets going outside the interface towards the finance web server.

  Corp1(config-if)#ip access-group 100 outCorp1(config-if)#end

  Important: To save your running config to startup before exit.

  Corp1#copy running-config startup-config

  Verifying the Configuration :

  Step1: Show ip interface brief command identifies the interface on which to apply access list . Step2: Click on each host A, B, C and D . Host opens a web browser page , Select address box of the web browser and type the ip address of finance

  web server(172. 22. 242. 23) to test whether it permits /deny access to the finance web Server.
