H12-211 : HCIA Routing & Switching : Part 08

1. A network requires a solution to allow 50 private IP addresses to be translated, however only a single public address is available for use.

   Which translation method can be used to support this requirement?

   • Static NAT
   • Dynamic NAT
   • Easy-IP
   • NAPT

2. NAPT allows for multiple internal addresses to be mapped to a single public address.

   How does NAT distinguish between the different private addresses when mapping to the same public address?

   • The source MAC address is used.
   • The destination MAC address is used.
   • The source port number is used.
   • The destination port number is used.

3. A web server in a private network is required to provide HTTP services to public users. The network administrator is required to configure NAT on RTA.

   

   Which configuration should be used?

   •  [RTA-Serial1/0/1]nat server protocol tcp global 202.10.10.1 www inside 192.168.1.1 8080
   • [RTA-Serial0/0/1]nat server protocol tcp global 192.168.1.1 www inside 202.10.10.1 8080
   • [RTA-Gigabitethernet0/0/1]nat server protocol tcp global 202.10.10.1 www inside 192.168.1.1 8080
   • [RTA- Gigabitethernet0/0/1]nat server protocol tcp global 192.168.1.1 www inside 202.10.10.1 8080

4. The network administrator needs to configure static NAT on RTA, in order to allow Host A to communicate with Host C.

   

   Which command is correct?

   • [RTA-Serial1/0/1]nat outbound 200.1.1.10
   • [RTA-Serial1/0/1]nat static global 200.1.1.10 inside 192.168.1.0
   • [RTA-Serial1/0/1]nat static global 192.168.1.1 inside 200.1.1.10
   • [RTA-Serial1/0/1]nat static global 200.1.1.10 inside 192.168.1.1

5. [RTA-GigabitEthernet0/0/0]nat outbound 2000 address-group 1

   Refer to the configuration output. What does the value “2000” refer to?

   • It represents the ACL number.
   • It represents the NAT number.
   • It represents the translated port number.
   • It represents the number of bytes that can be translated before the address is returned to the public address pool.

6. NAPT uses the same public address but different port numbers to translate private addresses.

   Which statement regarding the port number is correct?

   • It is necessary to configure port number mapping manually.
   • It is only necessary to configure the port number range.
   • It is not necessary to configure port numbers.
   • An access control list is needed to assign port numbers.

7. A configured internal host of a private network wishes to access the internet. What must be configured on the enterprise network egress router in order to achieve this? (Choose all that apply.)

8. Which of the following statements are correct about NAT? (Choose three)

   • NAT is the abbreviation for “Network Address Translation”.
   • NAT is used for translation between private and public network addresss.
   • When hosts inside a private network access the outside network, NAT is not required.
   • NAT provides an effective way to solve the problem of insufficient IP addresses.

9. Which of the following technologies can allow a host with IP address 10.0.0.1 to access the internet?

   • Static route
   • Dynamic route
   • Route import
   • NAT

10. Which of the following items can be translated by NAPT?

    • MAC address + port number
    • IP address + port number
    • Only MAC address
    • Only IP address

11. Which of the following statements about a designated port working in RIPv2 multicast mode are true? (Choose three)

    • The port receives only RIPv2 multicast packets.
    • The port does not receive RIPv1 broadcast packets.
    • The port does not receive RIPv2 broadcast packets.
    • The port receives only RIPv1 multicast packets.

12. Which of the following statements regarding the router ID in OSPF are incorrect? (Choose three)

    • The router IDs of OSPF routers in the same area must be the same, but can be different in different areas.
    • The router ID must be the IP address of an OSPF router interface.
    • The router ID must be configured manually.
    • A router running OSPF must have a router ID for it to operate properly.

13. Which of the following statements regarding Designated Routers in OSPF are correct? (Choose three)

    • DR is elected by all the routers in the same network segment.
    • If the priorities of two routers are different, the router with the lower priority will be elected as DR.
    • If the priorities of two routers are equal, the router with the higher Router ID will be elected as DR.
    • DR and BDR must be adjacent.

14. On the VRP platform, which of the following commands is used to configure the Router ID of a router as 1.1.1.1?

    • <Huawei>router id 1.1.1.1
    • [Huawei]router id 1.1.1.1
    • [Huawei]router-id 1.1.1.1

    • The IP address of the management interface.
    • The priority value of the router.
