Cisco 200-125 Online Questions & Answers

• Question 941:

  How many usable host are there per subnet if you have the address of 192.168.10.0 with a subnet mask of 255.255.255.240?

  A. 4
  B. 8
  C. 16
  D. 14
  D. 14

• Question 942:

  Which WAN topology is most appropriate for a centrally located server farm with several satellite branches?

  A. star
  B. hub and spoke
  C. point-to-point
  D. full mesh
  B. hub and spoke

  ---

  Explanation:

  In a Hub-and-spoke Site-to-Site Wide Area Network (WAN) network topology, one physical site act as Hub (Example, Main Office), while other physical sites act as spokes. Spoke sites are connected to each other via Hub site. In Hubandspoke Wide Area Network (WAN) topology, the network communication between two spokes always travels through the hub.

• Question 943:

  Refer to the exhibit.

  

  The two exhibited devices are the only Cisco devices on the network. The serial network between the two devices has a mask of 255.255.255.252. Given the output that is shown, what three statements are true of these devices? (Choose three.)

  A. The Manchester serial address is 10.1.1.1.
  B. The Manchester serial address is 10.1.1.2.
  C. The London router is a Cisco 2610.
  D. The Manchester router is a Cisco 2610.
  E. The CDP information was received on port Serial0/0 of the Manchester router.
  F. The CDP information was sent by port Serial0/0 of the London router.
  A. The Manchester serial address is 10.1.1.1.
  C. The London router is a Cisco 2610.
  E. The CDP information was received on port Serial0/0 of the Manchester router.

  From the output, we learn that the IP address of the neighbor router is 10.1.1.2 and the question stated that the subnet mask of the network between two routers is 255.255.255.252. Therefore there are only 2 available hosts in this network (22 ?2 = 2). So we can deduce the ip address (of the serial interface) of Manchester router is 10.1.1.1 ->. The platform of the neighbor router is cisco 2610, as shown in the output ->. Maybe the most difficult choice of this question is the answer E or F. Please notice that "Interface" refers to the local port on the local router, in this case it is the port of Manchester router, and "Port ID (outgoing port)" refers to the port on the neighbor router.

• Question 944:

  Refer to the exhibit. Traffic on the control plane uses which VLAN ?

  

  A. VLAN 1
  B. VLAN 5
  C. VLAN 10
  D. VLAN 20
  C. VLAN 10

• Question 945:

  Requirement to configure DHCP binding ( choose two)

  A. DHCP pool
  B. ip address
  C. Hardware address
  B. ip address
  C. Hardware address

• Question 946:

  Refer to the exhibit.

  

  Switch-1 needs to send data to a host with a MAC address of 00b0.d056.efa4. What will Switch-1 do with this data?

  A. Switch-1 will drop the data because it does not have an entry for that MAC address.
  B. Switch-1 will flood the data out all of its ports except the port from which the data originated.
  C. Switch-1 will send an ARP request out all its ports except the port from which the data originated.
  D. Switch-1 will forward the data to its default gateway.
  B. Switch-1 will flood the data out all of its ports except the port from which the data originated.

  ---

  This question tests the operating principles of the Layer 2 switch. Check the MAC address table of Switch1 and find that the MAC address of the host does not exist in the table. Switch1 will flood the data out all of its ports except the port from

  which the data originated to determine which port the host is located in.

  Switches work as follows:

  Switches learn the MAC addresses of PCs or workstations that are connected to their switch ports by examining the source address of frames that are received on that port.

  Machines may have been removed from a port, turned off, or moved to another port on the same switch or a different switch.

  This could cause confusion in frame forwarding.

  The MAC address entry is automatically discarded or aged out after 300 seconds If there is not MAC address of destination host in MAC table, switch sends broadcast to all ports except the source to find out the destination host. In output

  there is no MAC address of give host so switch floods to all ports except the source port.

• Question 947:

  How do you configure a hostname?

  A. Router(config)#hostname R1
  B. https://www.CertBus.com/200-125.html
  C. https://www.CertBus.com/200-125.html
  D. https://www.CertBus.com/200-125.html
  A. Router(config)#hostname R1

• Question 948:

  Which three circumstances can cause a GRE tunnel to be in an up/down state? (Choose three.)

  A. The tunnel interface IP address is misconfigured.
  B. The tunnel interface is down.
  C. A valid route to the destination address is missing from the routing table.
  D. The tunnel address is routed through the tunnel itself.
  E. The ISP is blocking the traffic.
  F. An ACL is blocking the outbound traffic.
  B. The tunnel interface is down.
  C. A valid route to the destination address is missing from the routing table.
  D. The tunnel address is routed through the tunnel itself.

• Question 949:

  Which value is used to build the CAM table?

  A. source IP address
  B. destination IP address
  C. destination MAC address
  D. source MAC address
  D. source MAC address

• Question 950:

  A network administrator is verifying the configuration of a newly installed host by establishing an FTP connection to a remote server. What is the highest layer of the protocol stack that the network administrator is using for this operation?

  A. application
  B. presentation
  C. session
  D. transport
  E. internet
  F. data link
  A. application
