  B. Configure the DHCP Option 82 field.
  C. Configure the global address pool if the DHCP server based on the global address pool is used.
  D. Configure the interface address pool if the DHCaP server based on the interface address pool is used.
  A. Enable DHCP globally.
  C. Configure the global address pool if the DHCP server based on the global address pool is used.

• Question 112:

  Which of the following statements regarding VRRP is false?

  A. The master in the VRRP group is selected based on priorities.
  B. The master sends gratuitous ARP packets, and notifies the connected device or host of its virtual MAC address.
  C. If the master fails, the new master is selected among backup devices based on priorities.
  D. The priority ranges from 1 to 255. When the backup received VRRP Advertisement packets which the priority is 0, the backup discards the packets.
  D. The priority ranges from 1 to 255. When the backup received VRRP Advertisement packets which the priority is 0, the backup discards the packets.

  A. They must be different.
  B. They must be the same.
  C. They may be the same.
  A. They must be different.

• Question 117:

  The TTL field encapsulated to the MPLS label header can prevent infinite loops of MPLS packets. Which of the following statements regarding the TTL field are true? (Multiple Choice)

  A. MPLS encapsulation in frame mode supports the TTL field. MPLS encapsulation in cell mode does not support the TTL field.
  B. MPLS provides two processing modes on the TTL field: 1. TTL in the MPLS header copies the IP TTL value when an IP packet enters the MPLS network. 2. The ingress LER sets the TTL value in the MPLS header to 255.
  C. The processing of IP TTL copy hides the LSR in a MPLS domain, improving the network security.
  D. If TTL copy is disabled, users can use the tracert function to view the LSR of the MPLS domain.
  A. MPLS encapsulation in frame mode supports the TTL field. MPLS encapsulation in cell mode does not support the TTL field.
  B. MPLS provides two processing modes on the TTL field: 1. TTL in the MPLS header copies the IP TTL value when an IP packet enters the MPLS network. 2. The ingress LER sets the TTL value in the MPLS header to 255.

• Question 118:

  A. Routing table
  B. MAC address table
  C. Session table

  A. TRUE

• Question 120:

  Which of the following statements regarding the LDP session establishment process are true? (Multiple Choice)

  A. Two LSRs send a Hello message to each other. If the Hello message carries the transport address, the LSR with a greater transport address initiates a TCP connection.
  B. If the Hello Message does not carry the transport address, destination IP addresses of the Hello Message are used to establish a TCP connection. The LSR with the larger IP address initiates a TCP connection.
  C. The initiator sends an Advertisement message to negotiate parameters for establishing an LDP session. These parameters include the LDP version, label distribution control mode, value of the Keepalive timer, maximum length of the PDU, and label space.
  D. If the responder accepts negotiated parameters, it sends an Initialization message and then a Keepalive message to the initiator.
  A. Two LSRs send a Hello message to each other. If the Hello message carries the transport address, the LSR with a greater transport address initiates a TCP connection.
  D. If the responder accepts negotiated parameters, it sends an Initialization message and then a Keepalive message to the initiator.
