• Question 604:

  Refer to the exhibit. The ABC Company has the internetwork in the exhibit. The administrator would like to reduce the size of the routing table on the Central router. Which partial routing table entry in the Central router represents a route summary that represents the LANs in Phoenix but no additional subnets?

  

  A. 10.0.0.0/22 is subnetted, 1 subnets D 10.0.0.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
  B. 10.0.0.0/28 is subnetted, 1 subnets D 10.2.0.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
  C. 10.0.0.0/30 is subnetted, 1 subnets D 10.2.2.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
  D. 10.0.0.0/22 is subnetted, 1 subnets D 10.4.0.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
  E. 10.0.0.0/28 is subnetted, 1 subnets D 10.4.4.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
  F. 10.0.0.0/30 is subnetted, 1 subnets D 10.4.4.4 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1
  D. 10.0.0.0/22 is subnetted, 1 subnets D 10.4.0.0 [90/20514560] via 10.2.0.2, 6w0d, Serial0/1

  ---

  All the above networks can be summarized to 10.0.0.0 network but the question requires to "represent the LANs in Phoenix but no additional subnets" so we must summarize to 10.4.0.0 network. The Phoenix router has 4 subnets so we need to "move left" 2 bits of "/24-> /22 is the best choice -D is correct.

• Question 605:

  Which QoS feature can change the value of the IPv4 Type of Service and the IPv6 Traffic Class header fields?

  A. shaping
  B. marking
  C. prioritization
  D. policing
  B. marking

• Question 606:

  Which parameter or parameters are used to calculate OSPF cost in Cisco routers?

  A. Bandwidth
  B. Bandwidth and Delay
  C. Bandwidth, Delay, and MTU
  D. Bandwidth, MTU, Reliability, Delay, and Load
  A. Bandwidth

  ---

  OSPF Cost The cost (also called metric) of an interface in OSPF is an indication of the overhead required to send packets across a certain interface. The cost of an interface is inversely proportional to the bandwidth of that interface. A higher bandwidth indicates a lower cost. There is more overhead (higher cost) and time delays involved in crossing a 56k serial line than crossing a 10M Ethernet line. The formula used to calculate the cost is:

  Cost= 10000 0000/bandwidth in bps

  For example, it will cost 10 EXP8/10 EXP7 = 10 to cross a 10M Ethernet line and will cost 10 EXP8/1544000 =64 to cross a T1 line. By default, the cost of an interface is calculated based on the bandwidth; you can force the cost of an interface with the ip ospf cost interface sub configuration mode command.

• Question 607:

  What Netflow component can be applied to an interface to track IPv4 traffic?

  A. flow monitor
  B. flow record
  C. flow sampler
  D. flow exporter
  A. flow monitor

  ---

  A flow monitor is essentially a NetFlow cache. The Flow Monitor has two major components the Flow Record and the Flow Exporter. The flow monitor can track both ingress and egress information. The flow record contains what information being tracked by NetFlow (i.e. IP address, ports, protocol...). The Flow exporter describes the NetFlow export. Flow monitors may be used to track IPv4 traffic, IPv6 traffic, multicast or unicast, MPLS, bridged traffic. Multiple Flow monitors can be created and attached to a specific physical or logical interface. Flow monitors can also include packet sampling information if sampling is required.

• Question 608:

  Scenario

  Refer to the topology. Your company has connected the routers R1, R2, and R3 with serial links. R2 and R3 are connected to the switches SW1 and SW2, respectively. SW1 and SW2 are also connected to the routers R4 and R5.

  The EIGRP routing protocol is configured.

  You are required to troubleshoot and resolve the EIGRP issues between the various routers. Use the appropriate show commands to troubleshoot the issues.

  Instructions

  Enter the IOS commands on the device to verify the network operations and to find the answers for the multiple-choice questions.

  THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION.

  Click the device to gain access to the console of the device. No console or enable passwords are required.

  To access the multiple-choice questions, click the numbered boxes on the left of the top panel.

  There are four multiple-choice questions with this task. Be sure to answer all four questions before clicking the Next button.

  

  

  

  Router R6 does not form an EIGRP neighbor relationship correctly with router R1. What is the cause for this misconfiguration?

  A. The values mismatch.
  B. The AS does not match.
  C. The network command is missing.
  D. The passive-interface command is enabled.
  C. The network command is missing.

  ---

  The link from R1 to R6 is shown below:

  

  As you can see, they are both using e0/0. The IP addresses are in the 192.168.16.0 network:

  

  

  But when we look at the EIGRP configuration, the "network 192.168.16.0" command is missing on R6.

  

  

• Question 609:

  Which three effects of using local SPAN are true? (Choose three.)

  A. It doubles the load on the forwarding engine.
  B. It prevents SPAN destinations from using port security.
  C. It doubles internal switch traffic.
  D. It reduces the supervisor engine workload by half.
  E. it reduces the load on the switch fabric.
  A. It doubles the load on the forwarding engine.
  B. It prevents SPAN destinations from using port security.
  C. It doubles internal switch traffic.

  ---

  To avoid disrupting traffic, do not oversubscribe any of these points in your SPAN topology. Some oversubscription and performance considerations are: SPAN doubles traffic internally SPAN adds to the traffic being processed by the switch fabric SPAN doubles forwarding engine load

  Because SPAN destination ports drop ingress traffic, these features are incompatible with SPAN destination ports: Private VLANs IEEE 802.1X port-based authentication Port security
