H12-211 : HCIA Routing & Switching : Part 14

1. Which SNMP version focuses on two main aspects, namely security and administration. The security aspect is addressed by offering both strong authentication and data encryption for privacy. The administration aspect is focused on two parts, namely notification originators and proxy forwarders.

   • SNMPv1
   • SNMPv2
   • SNMPv2c
   • SNMPv3

2. Which of the following route entries can be aggregated into 10.0.0.24/29? (Choose all that apply.)

   • 10.0.0.23/30
   • 10.0.0.26/30
   • 10.0.0.22/30

3. According to the configuration of single-armed routing in the following figure, the administrative department and finance department can communicate with each other even the proxy ARP is disabled on the subinterface on R1.

   

   • True
   • False 

4. Refer to the graphic.

   

   In the private network, RTA dynamically assigns a public address from the address pool to hosts
   without port translation. Host C wishes to access the public network while addresses are assigned to Host A and Host B. What will occur as a result?

   • The first public address will be allocated to Host C, and Host A will be forced offline.
   • The last public address will be allocated to Host C, and Host B will be forced offline.
   • Host C will be unable to forward traffic over the public network.
   • All hosts will have access to the public network through pool address swapping.

5. After the keepalive function is enabled for a GRE tunnel, the local end of the GRE tunnel sends a keepalive packet to the remote end every 10s.

   • True
   • False

6. Refer to the graphic.

   

   Both switches are operating using STP. With exception to those shown, all other default parameters have been maintained. Which port will be blocked?

   • Port G0/0/1 of switch A.
   • Port G0/0/2 of switch B.
   • Port G0/0/1 of switch B.
   • Port G0/0/2 of switch A.

7. Layer 2 switches are data link layer devices that identify MAC addresses of Layer 2 data frames and forward Layer 2 data frames based on MAC addresses. In addition, they record mappings between MAC addresses and interfaces in the MAC address table.

   • True
   • False

8. In RSTP mode, both alternate and backup ports cannot forward user traffic but can receive, process, and send BPDU.

   • True
   • False

9. Refer to the graphic.

   

   The switch is operating using STP. All default parameters have been maintained. Which port will be assigned a designated port role?

   •  G0/0/1 of switch A.
   • G0/0/2 of switch A.
   • E0/0/1 of the hub.
   • E0/0/2 of the hub.

10. How can the default route be generated? (Choose all that apply.)

    • Manually configured.
    • Automatically generated by the router.
    • Generated by dynamic routing protocols.
    • Generated by link layer protocols.

11. The following figure shows a routing table. When this router receives a packet with a destination IP address of 9.1.1.1, the router forwards the packet based on the route 9.1.0.0/16 because the matched bit number in this route is the largest.

    

    •  True
    • False

12. Refer to the graphic.

    

    The routing table includes direct routes and static routes and the preference of the direct routes cannot be changed.

    •  True
    • False

13. Refer to the graphic.

    

    Host A and Host B use VLAN routing to facilitate communication. When interface G0/0/1.2 of RTA receives a frame from Host B, what will RTA do?

    • RTA will immediately forward the frame via interface G0/0/1.1.
    • RTA remove the VLAN tag before forwarding the frame.
    • RTA will remove the VLAN tag and add a new tag for VLAN10 before forwarding the frame.
    • RTA will discard the frame.

14. Refer to the configuration output.

    

    Which of the following statements regarding the configuration output are correct? (Choose all that apply.)

    •  The PVID on interface GigabitEthernet0/0/1 is 10.
    • The PVID on interface GigabitEthernet0/0/1 is 1.
    • The PVID on interface GigabitEthernet0/0/2 is 10.
    • The PVID on interface GigabitEthernet0/0/2 is 1.

15. Refer to the graphic.

    

    VLANs 10 and 20 have been created on both SWA and SWC. VLAN 10 has been manually created on SWB. SWB has learned VLAN 20 from SWA via GVRP, allowing the hosts to belong to different VLANs as shown. If port Interface G0/0/1 on SWB is changed to fixed mode, what will happen?

    •  Host A will still be able to communicate with Host C.
    • Host B will still be able to communicate with Host D.
    • Hosts that belong to the same VLAN will still be able to communicate.
    • All hosts will be unable to communicate with any other host.

16. On Sx7 series switches, which of the following VLANs can be removed by using command “undo”? (Choose all that apply.)

    • vlan 1.
    • vlan 2.
    • vlan 1024.
    • vlan 4094.

17. Refer to the graphic.

    

    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
