Q91. Refer to the exhibit. Router RT1 has three equal-cost paths back to the source. Which configuration should be applied in order to load-balance the multicast traffic across all three links. 

A. Create three static multicast routes where each pointing out to one or three interfaces. 

B. Enable PIM multipath. 

C. Create a tunnel interface between RT1 and RT2. Enable PIM on the interface tunnel and disable PIM on the three interfaces part of equal-cost path between RT1 and RT2. 

D. PIM load balance is not possible. PIM only chooses one interface for RFC check and prunes the other interfaces.

A. Fast Peering Session Deactivation 

B. BGP Multihop 

C. reducing BGP scanner timing to the minimum that is supported 

D. TTL Security Check

Answer:


Q95. Refer to the exhibit. In the short-pipe QoS mode, this customer has QoS control for which two links? (Choose two.) 

A. a 

B. c 

C. d 

D. b 

E. e 

Answer: A,E 


Q96. A Service Provider connects to a client site that has two CEs. These CEs have a backdoor link for backup. OSPF is used as the routing protocol in this environment. You want to ensure that client traffic prefers the service provider connections for routing instead of the secondary connection. Which option describes the default behavior and the action that accomplishes your goal? 

A. The routes to the Service Provider are not preferred, due to the increased OSPF cost through the service provider network. Ensure that the cost on the links to the service provider are lower than the secondary connection. 

B. The routes to the Service Provider are seen as external type 1 in the OSPF database. Configure a domain ID that is the same across all PEs, to ensure that customers see routes as intra-area. 

C. The routes to the Service Provider are seen as inter-area OSPF routes through the network. Configure a sham link to create a new intra-area path across the service provider network between the PE routers that service the client. 

D. The routes to the Service Provider are seen as equal and cause nondeterministic traffic patterns. Ensure that the secondary connection has a higher cost than the links to the service provider.

Q97. A telecom company offers ISPs the ability to resell dynamic IP broadband services over its local loops, but it does not allow the resellers to install broadband network gateways. If an ISP wants to become a reseller but is unable to use NHRP, which tunneling protocol should be implemented? 

A. IP in IP 

B. IPsec 

C. L2TP 

D. GRE 

Answer:

Explanation: 

However, while OpenVPN can not be used with VoIP, L2TP can be used for VoIP. Only use this if OpenVPN is not available and you are in need of very high security/encryption. 


Q98. Which is one difference between H-VPLS and VPLS? 

A. VPLS is a point-to-point Layer-2 services and H-VPLS is a multipoint Layer-2 services. 

B. H-VPLS reduces signaling overhead and packet replication requirements for the provider edge. 

C. VPLS improve scalability concerns identified on H-VPLS implementation. 

D. H-VPLS connects using also other Layer-2 encapsulation such as PPP and VPLS connects using Ethernet encapsulation only 

Answer:

D. mpls traffic-eng multicast-intact 

E. mpls traffic-eng reoptimize 

Answer:
