Cisco 200-125 Online Questions & Answers

• Question 151:

  Which switching method checks for CRC errors?

  A. store-and-forward
  B. cut-through
  C. fragment-free
  D. Layer 3
  A. store-and-forward

  ---

  In cut-through switching, the switch copies into its memory only the destination MAC address (first six bytes of the frame) of the frame. After processing these first six bytes, the switch had enough information to make a forwarding decision

  and move the frame to the appropriate switchport. This switching method is faster than store-and-forward switching method.

  In store-and-forward switching, the switch copies each complete Ethernet frame into the switch memory and computes a Cyclic Redundancy Check (CRC) for errors. If a CRC error is found, the Ethernet frame is dropped. If no CRC error is

  found then that frame is forwarded.

• Question 152:

  Users on the 172.17.22.0 network cannot reach the server located on the 172.31.5.0 network. The network administrator connected to router Coffee via the console port, issued the show ip route command, and was able to ping the server.

  

  Based on the output of the show ip route command and the topology shown in the graphic, what is the cause of the failure?

  A. The network has not fully converged.
  B. IP routing is not enabled.
  C. A static route is configured incorrectly.
  D. The FastEthernet interface on Coffee is disabled.
  E. The neighbor relationship table is not correctly updated.
  F. The routing table on Coffee has not updated.
  D. The FastEthernet interface on Coffee is disabled.

  ---

  The default route or the static route was configured with incorrect next-hop ip address 172.19.22.2. The correct IP address will be 172.18.22.2 to reach server located on 172.31.5.0 network. IP route 0.0.0.0 0.0.0.0 172.18.22.2

• Question 153:

  Which protocol is the Cisco proprietary implementation of FHRP?

  A. HSRP
  B. VRRP
  C. GLBP
  D. CARP
  A. HSRP

• Question 154:

  Which two passwords must be supplied in order to connect by Telnet to a properly secured Cisco switch and make changes to the device configuration? (Choose two.)

  A. tty password
  B. enable secret password
  C. vty password
  D. aux password
  E. console password
  F. username password
  B. enable secret password
  C. vty password

  ---

  Telnet presents a potential security risk, so Telnet uses vty for connecting a remote Cisco switch. For access security, the vty password and enable password must be configured.

• Question 155:

  

  Why did Branch1 router lose WAN connectivity with R1 router?

  A. The IP address is misconfigured on PPP multilink interface on the Branch1 router.
  B. The PPP multilink group is misconfigured on the anch1 serial interfaces.
  C. The PPP multilink group is misconfigured on the R1 serial interfaces.
  D. The Branch1 serial interfaces are placed in a shutdown condition.
  A. The IP address is misconfigured on PPP multilink interface on the Branch1 router.

  ---

  Explanation: This question clearly stated there is a WAN connectivity issue between R1 and Branch1 so we should check both of them with the "show ip interface brief" command. On R1:

  

  On Branch1:

  

  We can see that although the Multilink1 interfaces are in "up/up" state but they are not in the same subnet. According to the IP address scheme shown on the topology we can deduce the Multilink interface on Branch1 has been misconfigured, it should be 192.168.14.2 instead.

• Question 156:

  Which command can you enter to block HTTPS traffic from the whole class A private network range to a host?

  A. R1(config)#access-list 105 deny tcp 10.1.0.0 0.0.255.255 40.0.0.2 0.0.0.0 eq 443
  B. R1(config)#access-list 105 deny tcp 10.1.0.0 0.0.255.255 40.0.0.2 0.0.0.0 eq 53
  C. R1(config)#access-list 105 deny tcp 10.0.0.0 0.255.255.255 40.0.0.2 0.0.0.0 eq 53
  D. R1(config)#access-list 105 deny tcp 10.0.0.0 0.255.255.255 40.0.0.2 0.0.0.0 eq 443
  D. R1(config)#access-list 105 deny tcp 10.0.0.0 0.255.255.255 40.0.0.2 0.0.0.0 eq 443

• Question 157:

  which command can you enter to verify that a router is synced with a configured time source ?

  A. Show ntp associations
  B. show ntp authenticate
  C. ntp server time
  D. ntp authenticate
  E. ntp associations
  A. Show ntp associations

• Question 158:

  Which command can you enter on a Cisco IOS device to enable a scheduled algorithm that directs lookup calls to multiple DNS hosts?

  A. ip domain round-robin
  B. ip name-server 192.168.10.14 192.168.10.15
  C. ip domain lookup
  D. ip domain list
  B. ip name-server 192.168.10.14 192.168.10.15

• Question 159:

  If a router has 3 hosts connected in one port and two other hosts connected in another port, how may broadcast domains are present on the router?

  A. 5
  B. 2
  C. 3
  D. 4
  B. 2

  Which command can you enter to verify link speed and duplex setting on the interface?

  A. router#show ip protocols
  B. router#show startup-config
  C. router#show line
  D. router#show interface gig 0/1
  D. router#show interface gig 0/1
