Q1. Due to recent acquisitions, a company's MPLS infrastructure is growing very quickly. Concerns anse about labeling service provider core network The IP address space is designed as per following: 

. Service provide ip address range is: 10.0.0.0/16 

. All loopback addresses use subnet mask/32 

. 10.0.0.0/24 range is used for loopback addresses 

. All other subnet masks used for links are /24 and /25 

Which command would significantly reduce the label allocations without compromising LDP functionalities? 

A. mpls Idp label 

allocate global host-routes 

B. ip prefix-list List1 deny 10.0.0J16 le 20 ge 25 

! 

mpls Idp label 

allocate global prefix-list List1 

C. access-list 1 permit 10.0.0.0.0.0.255.255 

mpls Idp neighbor 10.0.0.1 labels accept 3 

D. mpls Idp password required for 10 

! 

access-list 10 permit 10.0.0.1 

access-list 10 permit 10.0.0.2 

access-list 10 permit 10.0.0.3

Q2. Refer to the exhibit. 

A company has a requirement to provide communication among remote sites via multipoint GRE tunnels. This communication is not working yet. Which is the root cause of this issue? 

A. The key that is used on the DMVPN tunnel between the spoke and hub ends does not match. This causes the tunnel to fail. 

B. BGP IPv4 multicast address-family is missing between hub and spoke points. 

C. The GRE tunnel is not sourced from a physical interface. The DMVPN traffic does not know where to forward packets. 

D. The NHRP network ID does not match in the hub and spoke configuration causing NHRP negotiations to fail and the mGRE to stay down.
