Answer: B
Q3. In an OSPF network, users in a particular OSPF non-backbone area are complaining about slow access speeds to a shared corporate resource in another OSPF area. Traceroutes show that theusers are taking a suboptimal default route to the destinations. Which solution will improve access speed?
A. Make the area totally stubby so that the default can be followed along the best path.
B. Create a virtual link between the areas so that traffic can shortcut directly between them.
C. Implement policy routing to channel the traffic in the optimal direction.
D. Leak specific summaries on the ABRs for the remote subnets in addition to the default.
Answer: D
Q4. 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.
Answer: A
Q5. You have been tasked with designing a data center interconnect as part of business continuity. You want to use FCoE over this DCI to support synchronous replication. Which two technologies allow for FCoE via lossless Ethernet or data center bridging? (Choose two.)
A. EoMPLS
B. DWDM
C. Multichassis EtherChannel over Pseudowire
D. OTV
E. VPLS
F. SONET/SDH
Answer: BF
Q6. 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
Answer: B
Q7. Which design concern should be accounted for in all Layer 3 virtualization technologies?
A. Layer 3 redundancy
B. packet sizing
C. application usage
D. Layer 3 stability
Answer: B
Q8. You are designing a network using multipoint GRE tunnels and need to be able to detect when connectivity between the GRE tunnel endpoints is broken. Which statement is true about configuring keepalives for multipoint GRE tunnels?
A. The keepalive timer values on the routers must have the same value.
B. Both routers must support GRE tunnel keepalives.
C. No configuration is required to detect when connectivity is broken between the GRE tunnel endpoints.
D. GRE tunnel keepalives will not detect when connectivity is broken between the GRE tunnel endpoints.
Answer: D
Q9. You are designing a wireless LAN with the following components:
High-density indoor access point deployment
2.4-GHz and 5-GHz radios
802.11a, 802.11g, and 802.11n mode wireless LAN clients
Site survey results show negligible foreign WiFi and non-WiFi interference. What is the best method to decrease duty cycle (radio frequency utilization) and increase overall wireless LAN client performance for this design?
A. Disable all data rates below 12 Mb/s on all access points.
B. Decrease radio transmit power on all access points that report a high duty cycle.
C. Increase radio transmit power on all access points that report a high duty cycle.
D. Disable all data rates above 12 Mb/s on all access points.
E. Increase radio transmit power on all access points.
Answer: A
Q10. The Customer X network consists of an MPLS core, IS-IS running as IGP, a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements. The customer engineering department has some questions about the use of the Overload Bit in the IS-IS networks and how it could be used to improve their current network design. Which three options about the Overload Bit are true? (Choose three.)
A. It is not recommended on BGP route reflectors.
B. It only affects the use of the respective node as a transit node, and networks advertised within the LSPs of the node are still reachable.
C. It can be set on a router during the startup process for a fixed period of time.
D. It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node.
E. It can be set on a router until other interacting protocols have signaled convergence.
Answer: BCE
Q11. Acme Corporation indicates that their network design must support the ability to scale to support a high number of remote sites. Which IGP is considered to scale better for a hub-and-spoke topology?
A. BGP
B. OSPF
C. IS-IS
D. EIGRP
Answer: D
Q12. A switched network is being designed to support a manufacturing factory. Due to cost constraints, fiber-based connectivity is not an option. Which design allows for a stable network when there is a risk of interference from the manufacturing hardware in use on the factory floor?
A. Design the network to include UDLD to detect unidirectional links and take them out of service.
B. Design the network to include EtherChannel bundles to prevent a single-link failure from taking down a switch interconnection point.
C. Design the network to include loop guard to prevent a loop in the switched network when a link has too much interference.
D. Design the network to include BackboneFast on all devices to accelerate failure convergence times.
Answer: A
