  Explanation/Reference:

  HTTP and HTTPs run on TCP port 80 and 443, respectively and we have to remember them.

  Syslog runs on UDP port 514 while NTP runs on UDP port 123 so if we remember them we can find out the matching answers easily.

  But maybe there is some typos in this question as 2001:d88:800:200c::c/126 only ranges from 2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f (4 hosts in total).

  It does not cover host 2001:0D88:0800:200c::1f. Same for 2001:D88:800:200c::e/126, which also ranges from 2001:d88:800:200c:0:0:0:c to 2001:d88:800:200c:0:0:0:f and does not cover host 2001:0D88:0800:200c::1c.

  A. router ospf 1 default-information originate
  B. router ospf 1 network 0.0.0.0 0.0.0.0 area 0
  C. router ospf 1 redistribute connected 0.0.0.0
  D. router ospf 1 redistribute static subnets

• Question 535:

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  D. Option D

• Question 536:

  What is the failure detection time with BFD?

  A. 3 seconds
  B. less than a second
  C. 2 seconds
  D. 1 second
  B. less than a second

• Question 537:

  Which of the following commands will enable the DHCP and relay services on a Cisco router?

  A. RouterA(config)# service dhcp
  B. RouterA(config)# dhcp enable
  C. RouterA(config)# enable dhcp
  D. RouterA(config-if)# dhcp enable
  E. RouterA(config-if)# service dhcp
  A. RouterA(config)# service dhcp

  ---

  Using the service dhcp command at global configuration mode will enable the DHCP and relay services on a Cisco router. By default, these services are already enabled on the router, but they can be disabled using the no service dhcp command. Before the DHCP service can actually function, a pool of addresses must be created and any statically defined addresses (such as the router itself) must be excluded. If the router has two interfaces and needs to issue addresses on both interfaces two pools and two exclusion statements must be present.

  Below is an example of a complete configuration taken from a partial output of the show run command. This router has two interfaces 10.0.0.1/24 and 192.168.5.1/24, creating the need for two pools and two exclusion statements. It excludes the address ranges 10.0.0.1-10.0.0.5 from the 10.0.0.0/24 pool and excludes 192.168.5.1-192.168.5.5 from the 192.168.5.0/24 pool, and creates a pool for 10.0.0./24 and 192.168.5.0/24.

  

  The commands RouterA(config)# dhcp enable and RouterA(config)# enable dhcp are incorrect because the syntax is incorrect.

  The command RouterA(config-if)# dhcp enable is incorrect because the syntax is incorrect and because it is executed in interface configuration mode. Enabling DHCP is done at the global prompt.

  The command RouterA(config-if)# service dhcp is incorrect because it is executed in interface configuration mode. Enabling DHCP is done at the global prompt Objective:

• Question 538:

  Which of the following commands will display information about Type 4 LSAs?

  A. show ip ospf database external
  B. show ip ospf database asbr-summary
  C. show ip ospf database summary
  D. show ip ospf database router
  B. show ip ospf database asbr-summary

  ---

  The command show ip ospf database asbr-summary will display information about Type 4 LSAs. These LSAs provide next-hop information for areas that are receiving Type 5 or external LSAs. Consider the following sample output of the show ip ospf database asbr-summary command:

  

  The output shows that the router that sent this LSA is at 172.16.241.75. The router functioning as the ASBR is at 172.16.245.63. The advertising router, located at 172.16.241.75, is broadcasting that its best metric to reach the ASBR at 172.16.254.63 is 1.

  The command show ip ospf database external will not display information about Type 4 LSAs. It will display information about Type 5 LSAs, or External Link LSAs, instead of ASBR summary links, which are Type 4 LSAs.

  The command show ip ospf database summary will not display information about Type 4 LSAs. It will display information about summary links, or Type 3 LSAs, that are generated by an ABR, not summary links generated by an ASBR.

  The command show ip ospf database router will not display information about Type 4 LSAs. It will display information about router links, or Type 1 LSAs, instead of ASBR summary links, which are Type 4 LSAs.

  Sub-Objective:

  Describe OSPF packet types

  A. Configure AS_PATH prepend for the current best path
  B. Configure higher MED to select as the best path
  C. Configure AS_PATH prepend for the desired best path
  D. Configure lower LOCAL_PREF to select as the best path
  A. Configure AS_PATH prepend for the current best path

• Question 540:

  Refer to the exhibit.

  B. ABR-Rtr must configure the area 10 stub no-summary command.
  C. ABR-Rtr network type must be a broadcast network.
  D. ABR-Rtr must advertise the 0.0.0.0/0 default route in area 10.
  D. ABR-Rtr must advertise the 0.0.0.0/0 default route in area 10.
