H12-224 : HCNP-R&S Fast Track (Huawei Certified Network Professional – Routing & Switching Fast Track) : Part 08

1. In which of the following modes can the Eudemon be working? (Choose three.)

   • Routing mode
   • Transparent mode
   • Composite mode
   • Transfer mode

2. The end-to-end delay is the sum of transmission delays, processing delays, and queuing delays along the packet forwarding path.

   • True 
   • False

3. An address needs to be allocated to a host connected to the network temporarily or a group of IP addresses need to be allocated to the hosts that do not require permanent IP addresses. Which address allocation mode does the DHCP server use?

   • Automatic allocation
   • Dynamic allocation 
   • Manual allocation
   • All of the above

4. The urgent pointer in the flag field of an IPv4 packet header is generally used for OOB data transmission.

   • True 
   • False

5. Which fields does the DHCP binding table contain? (Choose three.)

   • MAC address 
   • route table
   • IP address lease time
   • Interface and VLAN

6. QoS in best-effort service mode uses which of the following queue scheduling technology?

   • FIFO 
   • WFQ
   • PQ
   • RR

7. Security policies for the firewall are applied to interzones but not to interfaces.

   • True 
   • False

8. Which of the following technologies does the Eudemon use to defense against Anti-DDoS attacks? (Choose five.)

   • TCP agent
   • Source authentication and detection
   • Crc check
   • Fingerprint identification (characteristics detection)
   • Abnormal session detection
   • Traffic control

9. Status detection is an advanced communication filtering mechanism. It checks the application layer protocol and monitors the status of the connection-based application layer protocol. For all connections, the status information about each connection is maintained by ASPF and is used to dynamically determine whether to permit or deny data packets to firewalls.

   • True 
   • False

10. Network address translation (NAT) translates only IP address information.

    • True
    • False 

11. Which of the following attacks are prevented after an IP address and MAC address are bound on the Eudemon? (Choose two.)

    • IP address spoofing
    • MAC address spoofing
    • DoS attack
    • DDoS attack

12. Different virtual firewall instances on an Eudemon must be configured with the same security policy.

    • True
    • False 

13. What are the types of DDoS attacks? (Choose three.)

    • Attacks by special packets
    • Scanning attack
    • Sniff attack
    • Application-layer attack 

14. What is the function of the client IP address field in DHCP messages?

    • It is used by the client in bound, renew, or rebinding state to respond to ARP request packets. 
    • It specifies the IP address allocated by the DHCP server to a client.
    • It specifies the next server address used in the BootStrap and is contained in DHCP Offer or DHCP ACK messages.
    • It specifies the DHCP relay address.

15. How many default zones does the Eudemon supporting multi-instance have?

    • Two
    • Three
    • Four
    • Five 

16. The Eudemon that is working in transparent mode detects processes data at Layer 2. Its interfaces are not configured with IP addresses.

    • True 
    • False

17. The firewall can be working in routing mode, transparent mode, or composite mode. The default mode is the composite mode.

    • True
    • False 

18. Which encapsulation mode is used for DHCP messages?

    • TCP encapsulation
    • RTP encapsulation
    • UDP encapsulation 
    • PPP encapsulation

19. The blacklist function on the firewall can filter packets based on destination IP addresses. A destination IP address can be dynamically added to or deleted from the blacklist.

    • True
    • False 

20. What about all outgoing labels in the label forwarding table of a device for the same route with the same next hop?

    • They must be different.
    • They must be the same. 
    • They may be the same.
