MPLS is short for multiprotocol label switching.
Which of the following statements regarding MPLS labels are true? (Multiple Choice)

• A.MPLS has multiple label distribution protocols, such as, Label Distribution Protocol (LDP).
• B.An MPLS label is a short fixed-length identifier with only local significance, and is used to uniquely indicate the FEC to which a packet belongs.
• C.MPLS supports single-layer labels and multi-layer labels.
• D.Similar to VPI/VCI in ATM packets and DLCI in Frame Relay packets, an MPLS label is a connection identifier.
• E.An MPLS label, carried in a packet header, does not contain topology information and is globally significance.

If security policy is not configured between firewall domains or when searching for a security policy, all security policies are not hit, the default packet filtering action between domains is performed by default. ( )

• A.Refusal to pass
• B.Different applications have different default actions
• C.Reporting administrator
• D.Only allowed to pass a part

The Agile Controller is an automated control system for network resources. It provides a unified policy engine to realize unified access control policies within the entire organization, and implements 5W1H-based (user identity, access time, access location, device type, device source, and access mode) authentication and authorization.

• A.FALSE
• B.TRUE

BFD (bidirectional forwarding detection) is a fast detection technology but is complex, It needs to be supported by special devices.

• A.FALSE
• B.TRUE

On the network shown in the following figure, all the devices run MPLS. The downstream switch SWA sends a label mapping message with IP address 1.1.1.1 to SWB. After SWB receives the label mapping message, it distributes a label to SWC. After SWC receives the label, it sends a label to SWD.

Which are the label distribution control mode and label advertisement mode on this network?

• A.Ordered + DU
• B.Independent + DU
• C.Ordered + DoD
• D.Independent + DoD
