Cisco 200-125 Online Questions & Answers

• Question 181:

  Which feature can you use to restrict SNMP queries to a specific OID tree?

  A. server group
  B. a community
  C. a view record
  D. an access group
  C. a view record

• Question 182:

  

  Why is the Branch2 network 10.1 0.20.0/24 unable to communicate with the Server farm1 network 10.1 0.10.0/24 over the GRE tunnel?

  A. The GRE tunnel destination is not configured on the R2 router.
  B. The GRE tunnel destination is not configured on the Branch2 router.
  C. The static route points to the tunnel0 interface that is misconfigured on the Branch2 router.
  D. The static route points to the tunnel0 interface that is misconfigured on the R2 router.
  C. The static route points to the tunnel0 interface that is misconfigured on the Branch2 router.

  ---

  The Branch2 network is communicating to the Server farm, which is connected to R2, via GRE Tunnel so we should check the GRE tunnel first to see if it is in "up/up" state with the "show ip interface brief" command on the two routers. On Branch2:

  

  On R2:

  

  We see interfaces Tunnel0 at two ends are "up/up" which are good so we should check for the routing part on two routers with the "show running-config" command and pay attention to the static routing of each router. On Branch2 we see:

  

  R2_show_run_static.jpg The destination IP address for this static route is not correct. It should be 192.168.24.1 (Tunnel0's IP address of R2), not 192.168.24.10 -> Answer C is correct. Note: You can use the "show ip route" command to check the routing configuration on each router but if the destination is not reachable (for example: we configure "ip route 10.10.10.0 255.255.255.0 192.168.24.10" on Branch2, but if 192.168.24.10 is unknown then Branch2 router will not display this routing entry in its routing table.

  A. Exstart
  B. 2-Way

  A. Process ID
  B. Router ID
  C. Public IP Address

  B. Router ID

• Question 185:

  Which two statements about wireless controllers are true? (Choose two)

  A. They provide Layer 2 services only
  B. They can be configured as virtual controllers to support autonomous access points
  C. They provide the configuration for managed access points on the network
  D. They are intended to directly manage a small number of access points
  E. At least one physical controller is needed to manage the virtual controllers of a network
  F. They can facilitate load balancing between access points
  C. They provide the configuration for managed access points on the network
  F. They can facilitate load balancing between access points

• Question 186:

  Refer to the topology shown in the exhibit.

  

  Which three ports will be STP designated ports if all the links are operating at the same bandwidth? (Choose three.)

  A. Switch A - Fa0/0
  B. Switch A - Fa0/1
  C. Switch B - Fa0/0
  D. Switch B - Fa0/1
  E. Switch C - Fa0/0
  F. Switch C - Fa0/1
  B. Switch A - Fa0/1
  C. Switch B - Fa0/0
  D. Switch B - Fa0/1

  This question is to check the spanning tree election problem.

  1.

  First, select the root bridge, which can be accomplished by comparing the bridge ID, the smallest will be selected. Bridge-id= bridge priority + MAC address. The three switches in the figure all have the default priority, so we should compare the MAC address, it is easy to find that SwitchB is the root bridge.

  2.

  Select the root port on the non-root bridge, which can be completed through comparing root path cost. The smallest will be selected as the root port.

  3.

  Next, select the Designated Port. First, compare the path cost, if the costs happen to be the same, then compare the BID, still the smallest will be selected. Each link has a DP. Based on the exhibit above, we can find DP on each link. The DP on the link between SwitchA and SwitchC is SwitchA'Fa0/1, because it has the smallest MAC address.

• Question 187:

  The network administrator has been asked to give reasons for moving from IPv4 to IPv6. What are two valid reasons for adopting IPv6 over IPv4? (Choose two.)

  A. no broadcast
  B. change of source address in the IPv6 header
  C. change of destination address in the IPv6 header
  D. Telnet access does not require a password
  E. autoconfiguration
  F. NAT
  A. no broadcast
  E. autoconfiguration

  ---

  IPv6 does not use broadcasts, and autoconfiguration is a feature of IPV6 that allows for hosts to automatically obtain an IPv6 address.

• Question 188:

  Refer to the diagram.

  

  All hosts have connectivity with one another. Which statements describe the addressing scheme that is in use in the network? (Choose three.)

  A. The subnet mask in use is 255.255.255.192.
  B. The subnet mask in use is 255.255.255.128.
  C. The IP address 172.16.1.25 can be assigned to hosts in VLAN1
  D. The IP address 172.16.1.205 can be assigned to hosts in VLAN1
  E. The LAN interface of the router is configured with one IP address.
  F. The LAN interface of the router is configured with multiple IP addresses.
  B. The subnet mask in use is 255.255.255.128.
  C. The IP address 172.16.1.25 can be assigned to hosts in VLAN1
  F. The LAN interface of the router is configured with multiple IP addresses.

  ---

  The subnet mask in use is 255.255.255.128: This is subnet mask will support up to 126 hosts, which is needed.

  The IP address 172.16.1.25 can be assigned to hosts in VLAN1: The usable host range in this subnet is 172.16.1.1-172.16.1.126

  The LAN interface of the router is configured with multiple IP addresses: The router will need 2 subinterfaces for the single physical interface, one with an IP address that belongs in each VLAN.

• Question 189:

  What is the default maximum number of equal-cost paths that can be placed into the routing table of a Cisco OSPF router?

  A. 2
  B. 8
  C. 16
  D. unlimited
  B. 8

  ---

  maximum-paths (OSPF)

  To control the maximum number of parallel routes that Open Shortest Path First (OSPF) can support, use the maximum-paths command.

  Syntax Description

  maximum

  Maximum number of parallel routes that OSPF can install in a routing table. The range is from 1 to 16 routes.

  Command Default

  8 paths

• Question 190:

  Configuration of which option is required on a Cisco switch for the Cisco IP phone to work?

  A. PortFast on the interface
  B. the interface as an access port to allow the voice VLAN ID
  C. a voice VLAN ID in interface and global configuration mode
  D. Cisco Discovery Protocol in global configuration mode
  B. the interface as an access port to allow the voice VLAN ID

  Configure the Switch Port to Carry Both Voice and Data TrafficWhen you connect an IP phone to a switch using a trunk link, it can cause high CPU utilization in the switches. As all the VLANs for a particular interface are trunked to the phone, it increases the number of STP instances the switch has to manage. This increases the CPU utilization. Trunking also causes unnecessary broadcast / multicast / unknown unicast traffic to hit the phone link. In order to avoid this, remove the trunk configuration and keep the voice and access VLAN configured along with Quality of Service (QoS). Technically, it is still a trunk, but it is called a Multi-VLAN Access Port (MVAP). Because voice and data traffic can travel through the same port, you should specify a different VLAN for each type of traffic. You can configure a switch port to forward voice and data traffic on different VLANs. Configure IP phone ports with a voice VLAN configuration. This configuration creates a pseudo trunk, but does not require you to manually prune the unnecessary VLANs. The voice VLAN feature enables access ports to carry IP voice traffic from an IP phone. The voice VLAN feature is disabled by default. The Port Fast feature is automatically enabled when voice VLAN is configured. When you disable voice VLAN, the Port Fast feature is not automatically disabled.
