how many questions of 352-001 exam question?

Q1. Company A has grown nationwide in the U.S., and each new remote branch has a Metro Ethernet circuit provisioned back to the data center at the headquarters on the West Coast. The operations team says that it cannot manage hundreds of circuits as the company continues to grow. You review the topology and notice that many of the branches are close to each other in geographical zones. How can you redesign this network to improve manageability and increase scalability? 

A. Add an aggregation layer router in each geographical zone. 

B. Add a redundant data center on the East Coast to serve some of the traffic there. 

C. Add a default route in each branch toward the data center on the West Coast. 

D. Use Optimized Edge Routing at the data center. 

E. Build an overlay MPLS network with Layer 3 VPN.

Q2. You are designing a large-scale DMVPN network with more than 500 spokes using EIGRP as the IGP protocol. Which design option eliminates potential tunnel down events on the spoke routers due to the holding time expiration? 

A. Increase the hold queue on the tunnel interface of the spoke routers. 

B. Increase the hold queue on the physical interface of the spoke routers. 

C. Increase the hold queue on the physical interface of the hub router. 

D. Increase the hold queue on the tunnel interface of the hub router. 

E. Apply QoS for pak_priority class.

Q3. A new video multicast application is deployed in the network. The application team wants to use the 239.0.0.1 multicast group to stream the video to users. They want to know if this choice will impact the existing multicast design. What impact will their choice have on the existing multicast design? 

A. Because 239.0.0.1 is a private multicast range, a flood of PIM packets that have to be processed by the CPU and hosts will be sent by the routers in the network. 

B. Because 239.0.0.1 is a private multicast range, the rendezvous point has to send out constant group updates that will have to be processed by the CPU and hosts. 

C. The multicast application sends too many packets into the network and the network infrastructure drops packets. 

D. The 239.0.0.1 group address maps to a system MAC address, and all multicast traffic will have to be sent to the CPU and flooded out all ports.
