Cisco 200-120 Online Practice Questions and Exam Preparation

Cisco 200-120 Online Questions & Answers

• Question 101:

  Which command is used to enable CHAP authentication, with PAP as the fallback method, on a serial interface?

  A. Router(config-if)# ppp authentication chap fallback ppp
  B. Router(config-if)# ppp authentication chap pap
  C. Router(config-if)# authentication ppp chap fallback ppp
  D. Router(config-if)# authentication ppp chap pap
  B. Router(config-if)# ppp authentication chap pap

  ---

  This command tells the router first to use CHAP and then go to PAP if CHAP isn't available.

• Question 102:

  Which two tasks does the Dynamic Host Configuration Protocol perform? (Choose two.)

  A. Set the IP gateway to be used by the network.
  B. Perform host discovery used DHCPDISCOVER message.
  C. Configure IP address parameters from DHCP server to a host.
  D. Provide an easy management of layer 3 devices.
  E. Monitor IP performance using the DHCP server.
  F. Assign and renew IP address from the default pool.
  C. Configure IP address parameters from DHCP server to a host.
  F. Assign and renew IP address from the default pool.

  ---

  The Dynamic Host Configuration Protocol (DHCP) is a network protocol used to configure devices that are connected to a network (known as hosts) so they can communicate on that network using the Internet Protocol (IP). It involves clients and a server operating in a client-server model. DHCP servers assigns IP addresses from a pool of addresses and also assigns other parameters such as DNS and default gateways to hosts.

• Question 103:

  A router has learned three possible routes that could be used to reach a destination network. One route is from EIGRP and has a composite metric of 20514560. Another route is from OSPF with a metric of 782. The last is from RIPv2 and has a metric of 4. Which route or routes will the router install in the routing table?

  A. the OSPF route
  B. the EIGRP route
  C. the RIPv2 route
  D. all three routes
  E. the OSPF and RIPv2 routes
  B. the EIGRP route

  ---

  When one route is advertised by more than one routing protocol, the router will choose to use the routing protocol which has lowest Administrative Distance. The Administrative Distances of popular routing protocols are listed below:

  

• Question 104:

  Which characteristics are representatives of a link-state routing protocol? (Choose three.)

  A. provides common view of entire topology
  B. exchanges routing tables with neighbors
  C. calculates shortest path
  D. utilizes event-triggered updates
  E. utilizes frequent periodic updates
  A. provides common view of entire topology
  C. calculates shortest path
  D. utilizes event-triggered updates

  ---

  Each of routers running link-state routing protocol learns paths to all the destinations in its "area" so we can say although it is a bit unclear. Link-state routing protocols generate routing updates only (not the whole routing table) when a change

  occurs in the network topology so Link-state routing protocol like OSPF uses Dijkstra algorithm to calculate the shortest path ->.

  Unlike Distance vector routing protocol (which utilizes frequent periodic updates), link-state routing protocol utilizes event-triggered updates (only sends update when a change occurs) ->.

• Question 105:

  What parameter can be different on ports within an EtherChannel?

  A. speed
  B. DTP negotiation settings
  C. trunk encapsulation
  D. duplex
  B. DTP negotiation settings

  ---

  For an etherchannel to come up, the speed, duplex and the trunk encapsulation must be the same on each end.

• Question 106:

  What is the default Syslog facility level?

  A. local4
  B. local5
  C. local6
  D. local7
  D. local7

  ---

  By default, Cisco IOS devices, CatOS switches, and VPN 3000 Concentrators use facility local7 while Cisco PIX Firewalls use local4 to send syslog messages. Moreover, most Cisco devices provide options to change the facility level from their default value.

• Question 107:

  Refer to the exhibit.

  

  An administrator pings the default gateway at 10.10.10.1 and sees the output as shown. At which OSI layer is the problem?

  A. data link layer
  B. application layer
  C. access layer
  D. session layer
  E. network layer
  E. network layer

  ---

  The command ping uses ICMP protocol, which is a network layer protocol used to propagate control message between host and router. The command ping is often used to verify the network connectivity, so it works at the network layer.

• Question 108:

  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

  ---

  Flow monitors are the Flexible NetFlow component that is applied to interfaces to perform network traffic monitoring. Flow monitors consist of a record and a cache. You add the record to the flow monitor after you create the flow monitor. The

  flow monitor cache is automatically created at the time the flow monitor is applied to the first interface. Flow data is collected from the network traffic during the monitoring process based on the key and nonkey fields in the record, which is

  configured for the flow monitor and stored in the flow monitor cache.

  For example, the following example creates a flow monitor named FLOW-MONITOR-1 and enters Flexible NetFlow flow monitor configuration mode:

  Router(config)# flow monitor FLOW-MONITOR-1

  Router(config-flow-monitor)#

• Question 109:

  What are three broadband wireless technologies? (Choose three.)

  A. WiMax
  B. satellite Internet
  C. municipal Wi-Fi
  D. site-to-site VPN
  E. DSLAM
  F. CMTS
  A. WiMax
  B. satellite Internet
  C. municipal Wi-Fi

• Question 110:

  Which item represents the standard IP ACL?

  A. access-list 110 permit ip any any
  B. access-list 50 deny 192.168.1.1 0.0.0.255
  C. access list 101 deny tcp any host 192.168.1.1
  D. access-list 2500 deny tcp any host 192.168.1.1 eq 22
  B. access-list 50 deny 192.168.1.1 0.0.0.255

  ---

  The standard access lists are ranged from 1 to 99 and from 1300 to 1999 so only access list 50 is a standard access list.
