Cisco 200-125 Online Questions & Answers

• Question 251:

  Which two statements about LLDP are true?(choose two)

  A. It uses mandatory TLVs to discover the neighboring devices
  B. It functions at Layer 2 and Layer 3
  C. It is a Cisco-proprietary technology
  D. It is implemented in accordance with the 802.11a specification
  E. It enables systems to learn about one another over the data-link layer
  A. It uses mandatory TLVs to discover the neighboring devices

• Question 252:

  Which statement about named ACLs is true?

  A. They support standard and extended ACLs.
  B. They are used to filter usernames and passwords for Telnet and SSH.
  C. They are used to filter Layer 7 traffic.
  D. They support standard ACLs only.
  E. They are used to rate limit traffic destined to targeted networks.
  A. They support standard and extended ACLs.

  ---

  Named Access Control Lists (ACLs) allows standard and extended ACLs to be given names instead of numbers. Unlike in numbered Access Control Lists (ACLs), we can edit Named Access Control Lists. Another benefit of using named access configuration mode is that you can add new statements to the access list, and insert them wherever you like. With the legacy syntax, you must delete the entire access list before reapplying it using the updated rules.

• Question 253:

  Which tow options describe benefits of aggregated chassis technology? (Choose two.)

  A. It requires only three IP addresses per VLAN.
  B. It reduces management overhead.

  D. It supports redundant configuration files.
  E. It supports HSRP, VRRP, and GLBP.
  F. Switches can be located anywhere regardless of their physical distance from one another.
  B. It reduces management overhead.
  C. It requires only one IP address per VLAN.

  B. The router uses interface GigabitEthernet0/0 to reach host address 10.111.35.106
  C. Three different networks are within the 10.0.0.0/8 range.
  D. The router uses interface Serial0/0/0/0 to reach network 192.168.1.0/24

• Question 259:

  SIMULATION

  Instructions

  To configure a router click on the console host icon in the topology.

  You can click on the buttons below to view the different windows.

  Each of the windows can be minimized by clicking on the [-]. You can also reposition a window by dragging it by the title bar.

  Most commands that use the "Control" or "Escape" keys are not supported and are not necessary to complete this simulation. The help command does not display all commands of the help system.

  Console access is available to switches SW1, SW2 and SW3.

  The console password configured on router HQ is cisco.

  (Console cable connected between PC and HQ.)

  Devices configurations are saved automatically and saving configurations is not required.

  You work as a network engineer for SASCOM Network Ltd company. On router HQ, a provider link has been enabled and you must configure an IPv6 default route on HQ and make sure that this route is advertised in IPv6 OSPF process.

  Also, you must troubleshoot another issue. The router HQ is not forming an IPv6 OSPF neighbor relationship with router BR.

  Topology Details

  Two routers HQ and BR are connected via serial links.

  Router HQ has interface Ethernet0/1 connected to the provider cloud and interface Ethernet0/0 connected to RA1.

  Router BR has interface Ethernet0/0 connected to another router RA2.

  IPv6 Routing Details

  All routers are running IPv6 OSPF routing with process ID number 100. Refer to the topology diagram for information about the OSPF areas. The Loopback 0 IPv4 access is the OSPF router ID on each router.

  Configuration requirements

  Configure IPv6 default route on router HQ with default gateway as 2001:DB8:B:B1B2::1

  Verify by pinging provider test IPv6 address 2001:DB8:0:1111::1 after configuring default route on HQ.

  Make sure that the default route is advertised in IPv6 OSPF on router HQ. This default route should be advertised only when HQ has a default route in its routing table.

  Router HQ is not forming IPv6 OSPF neighbor with BR. You must troubleshoot and resolve this issue.

  Special Note: To gain the maximum numbers of points, you must complete the necessary configurations and fix IPv6 OSPF neighbor issue with router BR. IPv6 OSPFv3 must be configured without using address families. Do not change the IPv6 OSPF process ID.

  

  A. Check the answer below.
  A. Check the answer below.

  ---

  Requirement (1): Configure IPv6 default route on router HQ with default gateway as 2001:DB8:B:B1B2::1.

  HQ(config)# ipv6 unicast routing

  HQ(config)# ipv6 route 0::/0 2001:DB8:B:B1B2::1

  Requirement (2): Verify by pinging provider test IPv6 address 2001:DB8:0:1111::1 after configuring default route on HQ.

  HQ# ping 2001:DB8:0:1111::1

  !!!!!

  Requirement (3): Make sure that the default route is advertised in IPv6 router HQ. This default route should be advertised only when HQ has a default route in its routing table.

  |Here you must advertise the default route in IPv6 OSPF on HQ|

  HQ(config) # ipv6 router ospf 100

  HQ(config-rtr) # default-information originate always

  HQ(config) # exit

  Requirement (4): Router HQ is not forming IPv6 OSPF neighbor with BR. You must troubleshoot and resolve this issue.

  1.

  Verify the OSPFv3 advertise on Serial 1/0 using the show run command: HQ#show run ! interface serial1/0 ! Note: Interface Serial 1/0 missing OSPFv3 advertise

  2.

  Advertise the OSPFv3 on Serial 1/0: HQ(config) # interface serial 1/0 HQ(config-if) # ipv6 ospf 100 area 0

  3.

  Verify after OSPFv3 advertise: HQ#show run ! interface serial1/0 IPV6 OSPF 100 area 0 ! Finally: Save the configuration HQ# copy running-config startup-config

  Make sure that the default route is advertised:

  |Here you must advertise the default route in IPv6 OSPF on HQ|

  HQ(config) # ipv6 router ospf 100

  HQ(config-rtr) # default-information originate always

  HQ(config) # exit

  Requirement (4): Router HQ is not forming IPv6 OSPF neighbor with BR. You must troubleshoot and resolve this issue.

  1.

  Verify the OSPFv3 advertise on Serial 1/0 using the show run command: Note: Interface Serial 1/0 missing OSPFv3 advertise

  2.

  Advertise the OSPFv3 on Serial 1/0: HQ(config) # interface serial 1/0 HQ(config-if) # ipv6 ospf 100 area 0

  3.

  Verify after OSPFv3 advertise: Finally: Save the configuration HQ# copy running-config startup-config
