Q41. Refer to the exhibit. 

How would you adjust the design to improve convergence on the network? 

A. Add an intra-POP link between routers 1A and 1B, and enable IP LFA FRR. 

B. Use an IP SLA between the end stations to detect path failures. 

C. Enable SSO-NSF on routers 1A and 1B. 

D. Use BGP to connect the sites over the WAN. 

Answer: A 

Q42. A large enterprise customer is migrating thousands of retail offices from legacy TDM circuits to an Ethernet-based service. The network is running OSPF and has been stable for many years. It is now possible to backhaul the circuits directly to the data centers, bypassing the regional aggregation routers. Which two networking issues need to be addressed to ensure stability with the new design? (Choose two.) 

A. Nothing will change if the number of offices is the same. 

B. Nothing will change if the number of physical interfaces stays the same. 

C. The RIB will increase significantly. 

D. The FIB will increase significantly. 

E. The amount of LSA flooding will increase significantly. 

F. The size of the link-state database will increase significantly. 

Answer: EF 

Q43. During a network design review, it is recommended that the network with a single large area should be broken up into a backbone and multiple nonbackbone areas. There are differing opinions on how many ABRs are needed for each area for redundancy. What would be the impact of having additional ABRs per area? 

A. There is no impact to increasing the number of ABRs. 

B. The SPF calculations are more complex. 

C. The number of externals and network summaries are increased. 

D. The size of the FIB is increased. 

Answer: C 

Q44. Refer to the exhibit. 

Which single design aspect should be configured on the ABRs to reduce the impact of WAN upgrades for spoke routers on the core of the network? 

A. route summarization 

B. stub area 

C. route filtering 

D. not-so-stubby area 

Answer: A 

Q45. Refer to the exhibit. 

You are designing a network using the Multiple Spanning Tree Protocol for loop avoidance. VLAN trunking is not allowed due to security requirements. Which option describes how you can design this Layer 2 network while using untagged interfaces between both switches? 

A. Assign VLAN 100 and VLAN 200 to the IST instance. 

B. Assign VLAN 100 and VLAN 200 to instance 1. 

C. Assign VLAN 100 to instance 1 and VLAN 200 to instance 2. 

D. Assign VLAN 100 to the IST instance and VLAN 200 to instance 1. 

Answer: C 

Q46. A junior engineer is implementing one of your optical designs and asks about CWDM (Coarse Wavelength Division Multiplexing). Which two features describe CWDM? (Choose two.) 

A. typically used over long distances, but requires optical amplification 

B. allows up to 32 optical carriers to be multiplexed onto a single fiber 

C. shares the same transmission window as DWDM 

D. uses the 850-nm band 

E. Passive CWDM devices require no electrical power. 

Answer: CE 

Q47. A company wants to connect two data center sites using a hub-and-spoke design with 2000 remote sites. One design consideration is the requirement to transfer MPLS packets over the public Internet. In addition, one router at each site should be used, and the MPLS packets must be encapsulated inside IP packets because the public Internet cannot transfer native MPLS packets. Which feature can be used to simplify the network design? 

A. GET VPN can be used to encrypt the MPLS packets with IPsec. 

B. DMVPN can be used to build up GRE tunnels dynamically with MPLS encapsulation inside. 

C. L2TPv3 can be used to encapsulate the MPLS packets. 

D. Site-to-site IPsec without GRE can be used to encapsulate the MPLS packets. 

E. PPPoE can be used to encapsulate the MPLS packets. 

Answer: B 

Q48. You are designing the QoS features for a large enterprise network that includes DMVPN. When would you need to configure QoS preclassify? 

A. when you are marking packets with the DSCP bits 

B. when you are marking packets with the TOS bits 

C. when your service provider requires the DSCP bits be set 

D. when the QoS policy cannot be based on DSCP ToS bits 

Answer: D 

Q49. A company would like to distribute a virtual machine (VM) hosting cluster between three data centers with the capability to move VMs between sites. The connectivity between data centers is IP only and the new design should use the existing WAN. Which Layer 2 tunneling technology do you recommend? 

A. VPLS 

B. L2TPv3 

C. OTV 

D. AToM 

Answer: C 

Q50. As part of the security protocol for your network design, you have designated that option 82 is enabled for DHCP snooping. When option 82 is enabled, which information will be added to the DHCP request? 

A. switch MAC address and VLAN, module, and port 

B. remote ID and circuit ID 

C. switch IP address and VLAN, module, and port 

D. switch MAC address and switch IP address 

Answer: A
