• Interface mode

The edge routers of the MPLS network, partial interface configurations on the IP access side are asfollows:[Quidway]diffserv domain default[Quidway-dsdomain-default]ip-dscp-inbound 10 phb ef green[Quidway-dsdomain-default]mpls-exp-outbound ef green map 5[Quidway-dsdomain-default]mpls-exp-inbound 4 phb ef green[Quidway-dsdomain-default]ip-dscp-outbound ef green map 18[Quidway-dsdomain-default]quit[Quidway] interface GigabitEthernet 2/0/0[Quidway-GigabitEthernet2/0/0] trust upstream default[Quidway-GigabitEthernet2/0/0] port-queue ef pq shaping 20 outboundWhich of the following statements about the preceding configurations are true?

• The trust upstream default command maps the DSCP priority to the corresponding EXP value when an IP packet enters the MPLS network and maps the EXP value to the corresponding DSCP priority when an IP packet leaves the MPLS network.
• If an IP packet with a DSCP value of 10 is sent to the MPLS network (non-PHP node) from GigabitEthernet 2/0/0, the corresponding EXP value is 5. If an MPLS packet with an EXP value of 4 is sent from GigabitEthernet 2/0/0, the DSCP value of the corresponding IP packet remains unchanged.
• The port-queue ef pq shaping 20 outbound command configures PQ scheduling and a maximum of 20 Mbit/s bandwidth for the EF queue when GigabitEthernet 2/0/0 sends IP packets.
• When GigabitEthernet 2/0/0 sends IP packets, the bandwidth of these sent IP packets can reach 1 Gbit/s if the EXP value is 4.

If a (*, G) entry exists in the RP, which of the following statements about the source registrationprocess are true in PIM-SM?

• The first hop DR connecting to the source encapsulates received multicast data into PIM registration information and unicasts the encapsulated information to the RP.
• The first-hop DR connecting to the source sends received multicast data to the RP hop by hop.
• The RP decapsulates registration information and uses RPT to send data packets to be sent to the multicast group to the outbound interface.
• The RP sends an (S, G) Join message hop by hop to the first hop DR connected to the multicast source to add the multicast source to the SPT.
• The RP unicasts a registration stop message to the first hop router connected to the multicast source.

On a city's dual-plane bearer network, PE1-A and PE1-B are two PEs in different planes of the city.Three CEs are on the same VPN. The OSPF is used to exchange VPN route information between CE1 and PE1-A and between CE 2 and PE1-B. The default route leading to PE1-A is configured on CE3, and a static route leading to CE 3 is configured on PE1-

• The static route is imported to the OSPF, and the OSPF route is imported to the VPN instance of the BGP. The MP-IBGP neighbor relationship is established among the PEs. Subinterfaces are enabled in the links between PEs and are bound to the same VPN to exchange VPN route information between PEs. How many routes on PE1-B can reach CE 3?
• Only one (The route leading to CE 3 is learned based on the IBGP neighbor relationship between PEs. The other route is filtered out by OSPF loopback detection.)
• Two (One route is learned based on the IBGP neighbor relationship between PEs, and the other one is the OSPF category-5 route.)
• No route
• Only the OSPF category-5 route can reach CE 3.

Which of the following reserved IP multicast addresses is the address of all PIM routers?

• 239.0.0.2
• 224 0 0.13
• 224.0.0.2
• 224 0 0 4

Which feature can make OSPF (or IS-IS) advertise MPLS TE tunnels as links?

• IGP Shortcut
• FA
• FRR
• SRLG

Which statement about primary VPN tunnel binding is false?

• Only the data destined for the specific peer device is transmitted through the n=bound primary VPN tunnel Data to other devices is transmitted using the default tunnel policy.
• Primary tunnel ensures that data can be transmitted from a VPN t a specific peer device permanently through a dedicate TE tunnel.
• Primary VPN tunnel binding means to bind a tunnel to a specific VPN. The bound tunnel is exclusive to the VPN.
• The bound primary tunnel can be selected sequentially.

What is the SSM group address range the IANA allocates for IPv4?

• 232.0.0.0/24
• 225.0.0.0/8
• 232.0.0.0/8
• 225.0.0.0/24

• Sends group-specified query messages for group 224.1.2.3.
• Deletes the record of group 224.1.2.3.
• Both A and B are correct.
• Neither A nor B is correct.

Which statement about the Hub s MPLS VPN networking is false?

• The Hub PE can receive the VPN_IPv4 routes advertised by all Spoke PEs.
• When an MP-IBGB neighbor relationship is established between two spoke PEs, the value of the Import VPN Target attribute of one Spoke PE can be the same as tat of the Export VPN Target attribute of the other Spoke PE.
• The Hub PE advertises the routes learned from one Spoke PE to other Spoke PEs. Therefore, Spoke sites can access other through the Hub site.
• All Spoke PEs can receive the VPN-IPv4 routes advertised by the Hub PE.
