Q61. You have designed a network to support two offices connected by a T1. Your router serial interfaces will be configured with encapsulation PPP. What will happen to your EIGRP neighbors if there is an LCP failure once your network is implemented? 

A. Your neighbors will drop after the EIGRP timers expire. 

B. Your neighbors will stay up because the link has not gone down. 

C. Your neighbors will drop immediately. 

D. Your neighbors will drop and EIGRP will begin the query process. 

Answer: D 

Q62. A network administrator is in charge of multiple IPsec VPN headend devices that service thousands of remote connectivity, point-to-point, IPsec/GRE tunnels. During a recent power outage, in which it was found that a backup power supply in one of those headend devices was faulty, one of the headend routers suffered a complete shutdown event. When the router was successfully recovered, remote users found intermittent connectivity issues that went away after several hours. Network operations staff accessed the headend devices and found that the recently recovered unit was near 100% CPU for a long period of time. How would you redesign the network VPN headend devices to prevent this from happening again in the future? 

A. Move the tunnels more evenly across the headend devices. 

B. Implement Call Admission Control. 

C. Use the scheduler allocate command to curb CPU usage. 

D. Change the tunnels to DMVPN. 

Answer: B 

Q63. Refer to the exhibit. 

What limitations exist in this design, given that the access layer devices are expected to steadily increase by two devices per week for the next year? 

A. scalability 

B. serviceability 

C. redundancy 

D. resiliency 

Answer: A 

Q64. A company plans to include Nonstop Forwarding and Bidirectional Forwarding Detection as a part of their network redundancy plan. In which two ways do NSF and BFD work together when different hardware platforms are compared? (Choose two.) 

A. During supervisor engine or routing engine failover, the NSF feature will always ensure that the BFD at the peer router will not trigger a link down independent of the used hardware platform. 

B. At some hardware platforms, BFD and NSF are not supported together. During supervisor engine or routing engine failover, the BFD at the peer router will trigger a link down. 

C. To ensure that BFD at the peer router will not trigger a link down during NSF, the BFD packets must be processed fast enough, and, during supervisor engine or routing engine failover, by processing the BFD independent from the supervisor engine or routing engine. 

D. Because BFD is always processed at the line cards (not at the supervisor engine or routing engine), a supervisor engine or routing engine failover will not affect the BFD peer router. 

E. Because BFD is always processed at the supervisor engine or routing engine, a supervisor engine or routing engine failover will always trigger a link down at the peer router. 

Answer: BC 

Q65. You have been hired by a startup company to provide optical services using MPLS-TP. Which three options describe reasons to use the MPLS-TP standard in your design? (Choose three.) 

A. MPLS-TP is a newer packet transport technology that replaces SONET/SDH. 

B. MPLS-TP includes extensions to native MPLS OAM for fault detection, monitoring, and propagation. 

C. MPLS-TP requires a routing protocol. 

D. MPLS-TP uses an IANA assigned label 13 for OAM. 

E. MPLS-TP uses Ethernet Y.1731 OAM. 

Answer: ABD 

Q66. Which two design aspects should a metro service provider consider when planning to deploy REP for his backbone? (Choose two.) 

A. Two REP segments can be connected redundantly at two points, one connection will be blocked as per the STP defined in IEEE 802.1d. 

B. UDLD can be enabled on REP interfaces to detect unidirectional failures. 

C. The guaranteed convergence recovery time is less than 50 ms for the local segment. 

D. A REP segment is limited to a maximum of seven devices. 

E. VLAN load balancing for optimal bandwidth usage is supported in any REP segment. 

Answer: BE 

Q67. Refer to the exhibit. 

Your company designed a network to allow server VLANs to span all access switches in a data center. In the design, Layer 3 VLAN interfaces and HSRP are configured on the aggregation switches. Which two features will improve STP stability within the network design? (Choose two.) 

A. BPDU guard on access ports 

B. Edge port on access ports 

C. Root guard on access ports 

D. BPDU guard on the aggregation switch downlinks toward access switches 

E. Root guard on the aggregation switch downlinks toward access switches 

F. Access switch pairs are explicitly determined to be root and backup root bridges 

Answer: AE 

Q68. Which mechanism should be added to a network design to identify unidirectional Spanning Tree Protocol failures through BPDU loss? 

A. UDLD 

B. loop guard 

C. BPDU guard? 

D. root guard 

Answer: B 

Q69. Your company requires two diverse multihop External Border Gateway Protocol peerings to a partner network. Which two methods would you use to improve lost peer detection? (Choose two.) 

A. Use Bidirectional Forwarding Detection for the peers. 

B. Use Selective Address Tracking and match the peers. 

C. Use subsecond keepalives for the peers. 

D. Use subsecond hold timers for the peers. 

E. Use Fast Peering Session Deactivation for the peers. 

F. Use subsecond minimum route advertisement Interval timers for the peers. 

Answer: BE 

Q70. Which two statements describe how including Cisco IPoDWDM proactive protection in an optical design would minimize packet loss in the event of a fiber cut? (Choose two). 

A. It uses the FEC field on the OTN frame to trigger protection. 

B. It uses a "not to exceed" predefined BER threshold to cause traffic redirection. 

C. It reroutes the optical circuit after an event that impacts service. 

D. It is effective both when you have redundant and nonredundant Layer 3 MPLS paths. 

Answer: AB
