In this star topology, router HKG is the hub. Routers SIN, SGN, and KUL are spokes and are not interconnected. A multicast source at 10.1.1.1 is functioning and able to send streams to all sites. A review of the network shows that PIM DM is configured on all interfaces. All routers are neighbors in OSPF. Receivers 10.2.1.12, 10.3.1.112, and
10.4.1.231 cannot receive the multicast stream, 232.0.0.1.
Which router configuration changes will resolve this issue?

A) [SIN-VLAN-interface200] igmp enable [KUL-VLAN-interface300] igmp enable [SGN-VLAN-interface400] igmp enable
B) [HKG] c-bsr looback 0 [HKG-pim] c-rp loopback 0
C) [HKG-pim] static-rp 10.1.254.1 preferred [SIN-pim] static-rp 10.1.254.1 preferred [KUL-pim] static-rp 10.1.254.1 preferred [SGN-pim] static-rp 10.1.254.1 preferred
D) [HKG-VLAN-interface100] igmp enable

All routers in the network shown in the exhibit are configured for OSPF and MPLS on all interfaces. Router P-3 and Router P-5 have two directly-connected LDP peers. Traffic from Router PE-1 destined for IP address 15.2.2.2 is label-swapped from P-3 to P-4.
Label-Switching Router P-3 allocates MPLS label 3001 for FEC 15.1.1.1 /32 and label 3002 for FEC 15.2.2.2 /32. LSR P-4 allocates MPLS label 4001 for FEC 15.1.1.1 /32 and MPLS label 4002 for FEC 15.2.2.2 /32.
Which MPLS label is advertised by PE-1 to P-3 for FEC 15.1.1.1 /32?

A) 3001
B) 3002
C) 0
D) 3
E) 1

Router-2 is configured for RIP version 2 on all interfaces. Router-1 and Router-3 are configured for RIP version 2 on all interfaces except for interface G 1/0/3.
Router-2 is also configured for OSPF on all interfaces. Router-1 and Router-3 are also configured for OSPF on all interfaces except for interface G 1/0/3.
A static route to subnet 16.1.2.0 /24 is configured on Router-1 pointing directly to Router-3. All other routing settings are set to default values. Host A sends an IP packet to Host B.
Which statement is true regarding this IP packet sourced from Host A and destined for Host B?

A) The IP packet travels from Router-1 to Router-3
B) The IP packet travels from Router-1 to Router-2 to Router-3
C) The IP packet is dropped by Router-1.
D) The IP packet loops between Router-1 and Router-2.

4. How many fields in the outer MPLS label change values on every LSR as the packet transits an MPLS network?

A) 5
B) 4
C) 2
D) 0
E) 3
F) 1

5. Click the Exhibit button.
All network routers shown in the exhibit are configured for OSPF and MPLS on all interfaces. Router P-3 and Router P-5 have two directly-connected LDP peers. Traffic from Router PE-1 destined for IP address 15.2.2.2 is label-swapped from P-3 to P-4.A link

between Router P-3 and
P-5 is introduced, but MPLS is not enabled on this new interface. The OSPF cost of the new link is smaller than the OSPF cost of the link from P-4 to P-5.Which statement is true about packets from PE-1 destined for IP address 15.2.2.2?

A) Router P-3 will send these packets directly to P-5 without an MPLS label.
B) Router PE-1 will send these packets to P-3 without an MPLS label.
C) Router P-3 will send these packets directly to P-5 with an MPLS label.
D) Router P-3 will continue to send these packets to P-4 with an MPLS label.
