Q21. To improve the stability of a global network, you have been tasked with changing the design to include link-state topology summarization. What are two issues that you should address as part of the design? (Choose two.)
A. slow convergence
B. suboptimal routing
C. traffic black-holing
D. packet reordering
Answer: BC
Q22. A company plans to use BFD between its routers to detect a connectivity problem inside the switched network. An IPS is transparently installed between the switches. Which packets should the IPS forward for BFD to work under all circumstances?
A. IP packets with broadcast IP source addresses
B. IP packets with identical source and destination IP addresses
C. fragmented packets with the do-not-fragment bit set
D. IP packets with the multicast IP source address
E. IP packets with the multicast IP destination address
F. IP packets with the destination IP address 0.0.0.0
Answer: B
Q23. Refer to the exhibit.
A customer runs OSPF with Area 5 between its aggregation router and an internal router. When a network change occurs in the backbone, Area 5 starts having connectivity issues due to the SPF algorithm recalculating an abnormal number of times in Area 5. You are tasked to redesign this network to increase resiliency on the customer network with the caveat that Router B does not support the stub area. How can you accomplish this task?
A. Set Area 5 to stubby at the ABR anyway.
B. Increase the bandwidth on the connection between Router A and Router B.
C. Turn on LSA throttling on all devices in Area 5.
D. Implement LSA filtering on the ABR, allowing summary routes and preventing more specific routes into Area 5.
E. Create a virtual link to Area 0 from Router B to the ABR.
Answer: D
Q24. What are two design advantages to using virtual port channel? (Choose two.)
A. enhanced system availability through multiple systems
B. reduced Spanning Tree Protocol convergence time
C. loop management without use of Spanning Tree Protocol
D. ability to use Spanning Tree Protocol blocked ports to forward traffic
E. enhanced ability to recover from Spanning Tree Protocol changes
Answer: AC
Q25. To meet specific business requirements, QoS-marked traffic must be sent over a dedicated link. Which technology fulfills this requirement?
A. MPLS
B. Q-in-Q tunneling
C. policy-based routing
D. EIGRP with modified metrics
Answer: C
Q26. Refer to the exhibit.
A new IPv4 multicast-based video-streaming service is being provisioned. During the design-validation tests, you realize that the link between the two buildings is carrying multicast traffic even when there are no receivers connected to the switch in Building B and despite IGMP snooping being enabled on both Layer 2 switches and IGMPv2 runs on the hosts. Which design change will prevent the multicast traffic from being unnecessarily flooded throughout the campus network?
A. Enable PIM snooping on both Layer 2 switches.
B. Enable multicast storm control on the link between Switch 1 and Switch 2.
C. Use static Layer 2 MAC forwarding entries on Switch 1.
D. Change the IPv4 multicast group address such that it excludes the usage of link-local MAC addresses.
E. Ensure that Switch 1 is an IGMP querier.
Answer: D
Q27. Your company plans to implement an Internet gateway router that is performing NAT. This same gateway will be terminating various IPsec tunnels to other remote sites. Which
address type isappropriate for the ACL that will govern the sources of traffic entering the tunnel in the inside interface?
A. inside local
B. inside global
C. outside local
D. outside global
Answer: B
Q28. Refer to the exhibit.
Which two options are two characteristics of the single-tier headend architecture for DMVPN designs? (Choose two.)
A. The mGRE and crypto functions are on the same router.
B. Each DMVPN cloud has two different headend routers for high availability purposes.
C. It is used in dual-cloud topologies for spoke-to-spoke connectivity.
D. It only supports hub-and-spoke connectivity.
E. Spokes cannot be used as RP in multicast deployments.
Answer: AC
Q29. 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
Q30. Tesla Radio GmbH is going to build a new research lab network based on a set of switches that would connect to their existing enterprise network. They are considering a design that would guarantee loop-free behavior within the set of switches. The design would also allow the group of switches to seem like a single switch to the enterprise network, because it is owned by a separate administrative group. Which Spanning Tree Protocol should be used to support the design requirements?
A. IEEE 802.1w
B. IEEE 802.1D
C. IEEE 802.1s
D. IEEE 802.1p
Answer: C
