H12-211 : HCIA Routing & Switching : Part 16

1. On the network shown in the figure, if all links are Ethernet links and all routers run OSPF, how many DRs will be elected on the entire network?

   

   •  2
   • 4
   • 3
   • 1

2. As shown in the preceding VTY configuration, the user privilege level is set to 3.

   

   • True
   • False

3. What is the main function of DHCP Discover packets?

   • The client sends DHCP Discover packets for requesting to confirm the configuration or renew the lease time of the IP address.
   • The DHCP server sends DHCP Discover packets to respond DHCP Request packets.
   • The DHCP Discover packet carries various configuration information.
   • The client sends DHCP Discover packets to search for the DHCP server.

4. As shown in the following figure, switch A and router A are connected through two links. The two links are aggregated in manual load balancing mode. The aggregation port number is 1. The aggregated link needs to carry VLAN tag 100. Switch A uses the trunk link.

   

   Which of the following configurations need to be performed on switch A?

   • 

   • 

   • 

   • 

5. What is the total length of the VLAN frame defined by IEEE 802.1Q?

   • 4
   • 3
   • 2
   • 1

6. Which of the following is the feature of port-based VLAN assignment?

   • VLAN IDs are allocated based on the protocol type and encapsulation format of data frames.
   • The VLAN does not need to be configured again when hosts move.
   • The VLAN tag is added to data frames based on the IP address carried in the frames.
   • The VLAN needs to be configured again when hosts move.

7. If an Ethernet data frame carries Length/Type = 0x8100, which of the following cannot be the payload of the data frame?

   • RSTP data frame
   • OSPF packet
   • ARP response packet
   • STP data frame

8. Which of the following statements about a port on a switch is false?

   

   • If the port receives data frames without VLAN tags, the switch needs to add VLAN tag 200.
   • If the VLAN tag carried in a data frame is 100, the switch removes the VLAN tag and sends the frame.
   • The link type of the port is trunk.
   • The port cannot send data frames carrying VLAN tag 200.

9. According to the following topology and configuration, R1 and R2 are connected through low-speed serial cables and PPP is used to encapsulate data link layer packets. When the Holdtime values of R1 and R2 are different, PPP negotiation and communication fail.

    • Routing mode
    • Tunnel mode
    • Transport mode
    • Switching mode

12. The IKE protocol is used to set up an SA for IPsec automatic negotiation. Identity authentication can be performed when the IP address of the initiator changes dynamically.

    • True
    • False
