Cisco 200-101 Online Questions & Answers

• Question 11:

  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

• Question 12:

  Refer to the exhibit.

  

  What is the meaning of the term dynamic as displayed in the output of the show frame-relay map command shown?

  A. The Serial0/0 interface is passing traffic.
  B. The DLCI 100 was dynamically allocated by the router
  C. The Serial0/0 interface acquired the IP address of 172.16.3.1 from a DHCP server
  D. The DLCI 100 will be dynamically changed as required to adapt to changes in the Frame Relay cloud
  E. The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned through Inverse ARP
  E. The mapping between DLCI 100 and the end station IP address 172.16.3.1 was learned through Inverse ARP

  ---

  The term dynamic indicates that the DLCI number and the remote router IP address 172.16.3.1 are learned via the Inverse ARP process. Inverse ARP is a technique by which dynamic mappings are constructed in a network, allowing a device such as a router to locate the logical network address and associate it with a permanent virtual circuit (PVC).

• Question 13:

  Refer to the exhibit.

  

  Host A pings interface S0/0 on router 3, what is the TTL value for that ping?

  A. 253
  B. 252 C. 255
  D. 254
  A. 253

  ---

  From the CCNA ICND2 Exam book: "Routers decrement the TTL by 1 every time they forward a packet; if a router decrements the TTL to 0, it throws away the packet. This prevents packets from rotating forever." I want to make it clear that

  before the router forwards a packet, the TTL is still remain the same. For example in the topology above, pings to S0/1 and S0/0 of Router 2 have the same TTL.

  The picture below shows TTL values for each interface of each router and for Host B. Notice that Host A initializes ICMP packet with a TTL of 255:

  

• Question 14:

  Refer to the exhibit.

  

  From R1, a network administrator is able to ping the serial interface of R2 but, unable to ping any of the subnets attached to RouterB. Based on the partial outputs in the exhibit, what could be the problem?

  A. EIGRP does not support VLSM.
  B. The EIGRP network statements are incorrectly configured.
  C. The IP addressing on the serial interface of RouterA is incorrect.
  D. The routing protocol has summarized on the classful boundary.
  E. EIGRP has been configured with an invalid autonomous system number.
  D. The routing protocol has summarized on the classful boundary.

  CCNA - EIGRP Common Question Reference: http://www.orbitco-ccna-pastquestions.com/CCNA---EIGRP-Common-Question.php

  If you look carefully at the R2 ip route, you will discover that the R2 does not learn any network from R1; this is because the routing protocol used here (EIGRP) performs auto summary when advertising routes to peers across a network. So in this case the address 172.17.0.0/26 is a summarized address. If the router was configured with no auto summary command, R2 LAN addresses would have been advertised and reached.

• Question 15:

  The following configuration is applied to a Layer 2 Switch:

  interface fastethernet 0/4 switchport mode access switchport port-security switchport port-security mac-address 0000.1111.1111 switchport port-security maximum 2 swithcport port-security

  What is the result of the above configuration being applied to the switch?

  A. A host with a mac address of 0000.1111.1111 and up to two other hosts can connect to FastEthernet 0/4 simultaneously
  B. A host with a mac address of 0000.1111.1111 and one other host can connect to Fast Ethernet 0/4 simultaneously
  C. Violating addresses are dropped and no record of the violation is kept
  D. The switch can send an SNMP message to the network management station
  E. The port is effectively shutdown
  B. A host with a mac address of 0000.1111.1111 and one other host can connect to Fast Ethernet 0/4 simultaneously
  D. The switch can send an SNMP message to the network management station

• Question 16:

  The internetwork infrastructure of company XYZ consists of a single OSPF area as shown in the graphic. There is concern that a lack of router resources is impeding internetwork performance. As part of examining the router resources, the OSPF DRs need to be known. All the router OSPF priorities are at the default and the router IDs are shown with each router.

  

  Which routers are likely to have been elected as DR? (Choose two.)

  A. Corp-1
  B. Corp-2
  C. Corp-3
  D. Corp-4
  E. Branch-1
  F. Branch-2
  D. Corp-4
  F. Branch-2

  ---

  There are 2 segments on the topology above which are separated by Corp-3 router. Each segment will have a DR so we have 2 DRs.

  To select which router will become DR they will compare their router-IDs. The router with highest (best) router-ID will become DR. The router-ID is chosen in the order below:

  The highest IP address assigned to a loopback (logical) interface.

  If a loopback interface is not defined, the highest IP address of all active router's physical interfaces will be chosen.

  In this question, the IP addresses of loopback interfaces are not mentioned so we will consider IP addresses of all active router's physical interfaces. Router Corp- 4 (10.1.40.40) and Branch-2 (10.2.20.20) have highest "active" IP addresses so they will become DRs.

• Question 17:

  

  

  If required, what password should be configured on the DeepSouth router in the branch office to allow a connection to be established with the MidEast router?

  A. No password is required.
  B. Enable
  C. Secret
  D. Telnet
  E. Console
  B. Enable

  In the diagram, DeepSouth is connected to Dubai's S1/2 interface and is configured as follows: Interface Serial1/2 IP address 192.168.0.5 255.255.255.252 Encapsulalation PPP ; Encapsulation for this interface is PPP Check out the following Cisco Link: http://www.cisco.com/en/US/tech/tk713/tk507/technologies_configuration_example09186a0080 094333.shtml#configuringausernamedifferentfromtheroutersname Here is a snipit of an example: Network Diagram If Router 1 initiates a call to Router 2, Router 2 would challenge Router 1, but Router 1 would not challenge Router 2. This occurs because the ppp authentication chap callin command is configured on Router 1. This is an example of a

  unidirectional authentication.

  In this setup, the ppp chap hostname alias-r1 command is configured on Router 1. Router 1 uses "alias-r1" as its hostname for CHAP authentication instead of "r1." The Router 2 dialer map name should match Router 1's ppp chap hostname;

  otherwise, two B channels are established, one for each direction.

  

• Question 18:

  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

  http://www.cisco.com/en/US/tech/tk365/technologies_white_paper09186a0080094e9e.shtml#t6

  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 19:

  Refer to the exhibit.

  

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

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  B. Option B

  ---

  http://networklessons.com/eigrp/eigrp-neighbor-and-topology-table-explained/

  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 20:

  What are three values that must be the same within a sequence of packets for Netflow to consider them a network flow? (Choose three.)

  A. source IP address
  B. source MAC address
  C. egress interface
  D. ingress interface
  E. destination IP address
  F. IP next-hop
  A. source IP address
  D. ingress interface
  E. destination IP address
