Q21. A Service Provider is designing a solution for a managed CE service to a number of local customers using a single CE platform and wants to have logical separation on the CE platform using Virtual Routing and Forwarding (VRF) based on IP address ranges or packet length. Which is the most scalable solution to provide this type of VRF Selection process on the CE edge device? 

A. Static Routes for Route Leaking 

B. Policy Based Routing 

C. Multi-Protocol BGP 

D. OSPF per VRF Instance 


Q22. A company plans to establish a new network using Cisco Catalyst switches for its multicast applications. What is the disadvantage when two multicast applications are using the multicast IP addresses and inside the same network? 

A. Multicast packets from both applications are flooded to all Layer 2 ports in a segment where a multicast receiver is located. 

B. Multicast packets from both applications are flooded to ports where one multicast receiver from one application is located. 

C. Only one multicast stream is received at the port where the receivers from both applications are located. 

D. Both multicast senders will always receive the multicast packets from the other multicast application. 

E. The routers doing PIM-SM cannot distinguish between the two multicast applications. 


Q23. Which restriction prevents a designer from using a GDOI-based VPN to secure traffic that traverses the Internet? 

A. Enterprise host IP addresses are typically not routable. 

B. GDOI is less secure than traditional IPsec. 

C. Network address translation functions interfere with tunnel header preservation. 

D. The use of public addresses is not supported with GDOI. 


Q24. Refer to the exhibit. 

After this new OSPF design with per-packet load balancing was implemented, Host A reported that large file downloads from Server A became slow and sometimes failed. The operations team discovered that packets are arriving out of order on R1. Which cost-conscious redesign action will fix the issue? 

A. Upgrade all links to 10 Gbps. 

B. Add an IP SLA probe on R1 and R4. 

C. Adjust the OSPF auto-cost reference bandwidth on R4. 

D. Adjust the OSPF auto-cost reference bandwidth on all routers. 


Q25. If a network design must support rapid convergence on half-duplex interfaces, which IEEE 802.1w capability should be used? 

A. root guard 

B. proposal-agreement handshake 

C. loop guard 

D. UplinkFast

Q26. Which three factors slow down network convergence? (Choose three.) 

A. constant interface flapping 

B. lack of redundant paths 

C. inconsistent topology states between routers 

D. transport network failing to generate LoS 

E. wrong summarization in ABRs 

Answer: ACD 

Q27. Refer to the exhibit. 

Acme Corporation hired you as a network designer to upgrade their network so that it supports IPv4 and IPv6 multicast. Which two protocols are needed on the LAN switch? (Choose two.) 

A. PIM sparse mode 

B. IGMP snooping 

C. PIM snooping 

D. Source Specific Multicast 

E. MLD snooping 

Answer: BE 

Q28. 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. 


Q29. Your design plan includes mutual redistribution of two OSPF networks at multiple locations, with connectivity to all locations in both networks. How is this accomplished without creating routing loops? 

A. Use route maps on the ASBRs to allow only internal routes to be redistributed. 

B. Use route maps on the ASBRs to allow internal and external routes to be redistributed. 

C. Use route maps on the ASBRs to set tags for redistributed routes. 

D. Use route maps on the ASBRs to filter routes with tags so they are not redistributed. 


Q30. Refer to the exhibit. 

Your company designed a network to allow server VLANs in a data center to span all access switches. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches. In which three ways should the design of the STP domain be optimized for server and application performance? (Choose three.) 

A. Use loop guard on access ports. 

B. Use PortFast on access ports. 

C. Use root guard on access ports. 

D. Align Layer 2 and Layer 3 forwarding paths. 

E. Use BPDU Skew Detection on access ports. 

F. Explicitly determine root and backup root bridges.
