Q71. Refer to the exhibit. 

Which two options provide the best loop protection in this topology, regardless of a bridged domain configuration? (Choose two.) 

A. PVRSTP on all switches 

B. REP on all switches 

C. MST on all switches 

D. BPDU guard on Switch A and Switch D 

E. 8032 on ring A-B-C-D 

Answer: BE 

Q72. Which two factors can significantly affect the OSPF network convergence time? (Choose two.) 

A. the tuning of OSPF LSA timers 

B. the number of OSPF routes 

C. the diameter of the OSPF network 

D. different processor capabilities of devices 

Answer: AD 

Q73. 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 

Q74. 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 

Q75. A network designer is redesigning an enterprise campus network to ensure that Ethernet switches proactively attempt to reconnect after a fiber cut. In the design, they will have to address areas where fiber cuts exist on campus from past troubleshooting, where a single fiber is disconnected in the fiber pair, leading to looping. Which feature could be implemented in the design to allow the Spanning Tree Protocol on the switches to be protected? 

A. loop guard 

B. UniDirectional Link Detection 

C. UniDirectional Link Detection aggressive mode 

D. root guard 

Answer: C

Q76. You are redesigning an OSPF v2 network and must migrate some links. You are concerned that there are different subnet masks. Which two link types will still form an OSPF adjacency even if there are subnet mask mismatches? (Choose two.) 

A. virtual 

B. broadcast 

C. point-to-multipoint 

D. non-broadcast 

E. point-to-point 

Answer: AE 

Q77. Which three reasons to deploy an IDS sensor in promiscuous mode when you design a security solution are true? (Choose three.) 

A. Solution should be resistant to sensor failure. 

B. Solution should allow for stream normalization. 

C. Solution should not impact jitter and latency for voice traffic. 

D. Solution should allow for signature-based pattern matching. 

E. Solution should allow to deny packets inline. 

Answer: ACD 

Q78. A network design shows two routers directly connected to an Ethernet switch using optical connections. There is an OSPF adjacency between the routers. In this design, which solution will ensure that interface down detection is reported as quickly as possible to the IGP? 

A. optimized OSPF SPF timers 

B. Bidirectional Forwarding Detection 

C. automatic protection switching 

D. optimized OSPF LSA timers 

E. Ethernet OAM CFM monitoring 

Answer: B 

Q79. A network designer wants to improve a company network design due to multiple network crashes. Which technology would allow for the restore of a network connection without informing the Layer 3 protocol? 

A. Bidirectional Forwarding Detection 

B. automatic protection switching 

C. UniDirectional Link Detection 

D. Ethernet OAM 

Answer: B 

Q80. Voice traffic between two campus enterprise networks is growing. The network designers decide to add a second 10-Mb Metro Ethernet service parallel to their original 10-Mb service in order to provide more bandwidth and diversity. The QoS profile will be the same on the new 10-Mb service due to the voice stability on the first Metro Ethernet link. When the second link is added to the OSPF domain, which traffic design consideration would have the most impact on the voice traffic when both links are active? 

A. per-destination IP address basis 

B. per-flow basis 

C. per-packet basis 

D. per-source IP address basis 

Answer: C
