Q31. A company wants to use an external appliance between its data center and WAN to optimize email and HTTP communications. The traffic flow must pass this appliance in both directions. The appliance is connected with only one interface to a Cisco IOS router and has a single IP address. Which two adjustments can you make to the network design so that the appliance is added into the traffic path? (Choose two.) 

A. Configure static routes to route the traffic to the appliance. 

B. Adjust the dynamic routing to route the traffic to the appliance. 

C. Configure NAT to force the traffic to the appliance. 

D. Configure a route map at the data center-side interface to forward the traffic to the appliance IP address. 

E. Configure a route map at the appliance-facing interface to forward the traffic to the appliance IP address. 

F. Configure a route map at the WAN-side interface to forward the traffic to the appliance IP address. 

Answer: DF 


Q32. When creating a network design that routes an IGP over L2VPNs, with which device does the remote CE router form an IGP adjacency? 

A. the hub site PE router 

B. the hub site CE router 

C. the directly connected PE router 

D. The IGP will not establish adjacency over the MPLS network. 

Answer:


Q33. Company X will be integrating an IPv6 application into their network and wants to develop a test environment to evaluate application performance across the network. This application will require both unicast and multicast communications. The company can do this implementation only in certain areas of its existing IPv4-only network, but wants all areas to communicate with each other. When developing the design to provide connectivity between these testing locations, what tunneling technology would work in this scenario? 

A. ISATAP 

B. 6to4 

C. DMVPN 

D. 6vPE 

E. 6PE 

Answer:


Q34. There is an MPLS-enabled link constantly flapping on an MPLS VPN network. Given that the network runs OSPF as the IGP protocol, which design mechanism will stabilize the network and avoid constant reconvergences? 

A. BFD 

B. IP Event Dampening 

C. OSPF fast hellos 

D. partial SPF 

Answer:


Q35. You have been asked to design a high-density wireless network for a university campus. Which three principles would you apply in order to maximize the wireless network capacity? (Choose three.) 

A. Increase the number of SSIDs to load-balance the client traffic. 

B. Choose a high minimum data rate to reduce the duty cycle. 

C. Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used. 

D. Enable 802.11ag channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput. 

E. Use directional antennas to achieve better sector separation channel reuse. 

F. Implement a four-channel design on 2.4 GHz to increase the number of available channels. 

Answer: BCE 


Q36. You are evaluating convergence characteristics of various interior gateway protocols for a new network design. Which technology allows link-state routing protocols to calculate paths to destination prefixes that are functionally similar to feasible successors in Enhanced Interior Gateway Routing Protocol? 

A. Incremental Shortest Path First 

B. Cisco Multiprotocol Label Switching Traffic Engineering Fast Reroute 

C. Loop-Free Alternate Fast Reroute 

D. partial route calculation 

E. Fast-Flooding 

Answer:


Q37. Refer to the exhibit. 

Four customer sites are connected through an EoMPLS-based VPLS over an MPLS provider. You are migrating from OSPF to multi-level IS-IS as the routing protocol to run on the four CE routers, and connectivity between all four sites is required. You want to control which CE or CEs will be elected as the Designated Intermediate System. Which two key aspects should be taken into account? (Choose two.) 

A. The DIS role for Level1 and Level2 can be performed by different routers. 

B. The CE with the second highest priority will be elected as the backup DIS on the LAN segment. 

C. One of the CE routers will be elected as the DIS based on interface priority then highest MAC address. 

D. It is recommended to use point-to-point link type on the CEs. 

E. If a new CE router is added to the VPLS cloud with a lower interface priority it will become the DIS. 

Answer: AC 


Q38. A many-to-many enterprise messaging application is using multicast as a transport mechanism. As part of the network design for this application, which multicast address should be used, according to best practices outlined in RFC 2365? 

A. 224.0.0.60 

B. 232.192.0.60 

C. 239.128.0.60 

D. 239.193.0.60 

Answer:

C. PIM snooping 

D. Source Specific Multicast 

E. MLD snooping
