Question 51

Which of the following deployment modes are recommended for LAN-side APs on small and midsize campus networks based on the Huawei CloudCampus Solution? (Choose two.)

  1. Deployment through the registration query
  2. Email-based deployment
  3. DHCP option-based deployment
  4. CLI-based deployment

Question 52

On the network shown in the following figure, 802.1X authentication is deployed on GE0/0/1 of SW2. Which of the following statements are correct?

  1. When MAC address-based access control is used, 802.1X clients A and B must be authenticated separately before they can obtain corresponding network access permissions.
  2. When interface-based access control is used, 802.1X client B can use network resources without being authenticated if 802.1X client A is successfully authenticated.
  3. Assume that SW2 uses MAC address-based access control mode and 802.1X client A passes authentication first. If 802.1X client A goes offline first, then 802.1X client B will still have the corresponding network access permissions because the interface status remains unchanged.
  4. Assume that SW2 uses the interface-based access control mode and 802.1X client A passes authentication first. If 802.1X client A goes offline first, then 802.1X client B will lose the corresponding network access permissions.

Question 53

MPLS supports forwarding equivalence class (FEC). Which of the following cannot be used as a FEC allocation standard?

  1. Fragment offset
  2. Destination address
  3. Application protocol
  4. Class of Service (CoS)

Question 54

Which of the following statements is incorrect?

  1. LSPs are classified into static and dynamic ISPs. A static LSP is manually configured by an administrator. A dynamic LSP is dynamically established using routing and label distribution protocols.
  2. When labels are allocated manually, ensure that the outgoing label of an upstream node is the same as the incoming label of the downstream node.
  3. LSPs created by static Distribution labels can be dynamically adjusted according to network topology changes, without the need for administrator intervention.
  4. Dynamic LSPs are established using label distribution protocols such as MP-BGP RSVP-TE and LDP.

Question 55

Which of the following statements regarding MPLS label space is incorrect?

  1. The label space 16-1023 is shared by static LSPs and static CR-LSPs.
  2. The label space 1024 and higher is shared by dynamic signaling protocols, such as LDP, RSVPTE and MP-BGP.
  3. When the last hop receives packets with the label value 0, it directly drops the packets.
  4. When the penultimate-hop LSR performs label switching, if it finds that the label value after the switching is 3, then it pops out the label and sends the packet to the last hop.
