Q21. You have created a network design that has two point-to-point Metro Ethernet circuits extending a single production VLAN between two data centers. Under normal circumstances, one circuit will carry traffic and spanning tree will block the other. If the company wants you to make use of both circuits to carry production traffic, which two technologies and features will you investigate to integrate into your network design? (Choose two.) 

A. EtherChannel 

B. MST 

C. Multichassis EtherChannel 

D. PVST+ 

Answer: AC 

Q22. 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 

Q23. A company wants a design that would support OSPF through a service provider ATM network. Which two OSPF network types should the designer use to establish OSPF neighborship between OSPF routers through the ATM network? (Choose two.) 

A. A broadcast network will always work through ATM networks. 

B. A broadcast network will work when the broadcast support is explicitly configured at the ATM network. 

C. Explicit neighbor statements are required when a nonbroadcast network is configured. 

D. Explicit neighbor statements are required when a point-to-multipoint network is configured. 

E. A nonbroadcast network does not require DR selection. 

Answer: BC 

Q24. Refer to the exhibit. 

Service Provider A and Service Provider B have agreed to a strategic interconnect relationship that will allow them access into each other's geographies by using an inter-AS eBGP VPNv4 multihop between route reflectors. Which two options will accomplish this scenario? (Choose two.) 

A. RR 1 and RR 2 peer using multihop eBGP VPNv4 to exchange prefixes. 

B. ASBR 1 and ASBR 2 act as inline route reflectors that set themselves as the next-hop. 

C. An LSP is formed between ASBR 1 and ASBR 2 using eBGP IPv4. 

D. An LSP is formed between ASBR 1 and ASBR 2 using eBGP VPNv4. 

E. RR 1 and RR 2 peer using multihop eBGP IPv4 to exchange prefixes. 

Answer: AC 

Q25. A network design includes a long signaling delay in notifying the Layer 3 control plane that an interface has failed. Which two of these actions would reduce that delay? (Choose two.) 

A. Enable lower data link layer recovery systems to have an opportunity to restore the interface. 

B. Increase the notification of interface flaps. 

C. Reduce the time for the network to reconverge. 

D. Increase network stability. 

Answer: AD

Q26. 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 

Q27. When a multiprotocol environment is designed to have several routers redistribute among the routing domains, how can routing loops be avoided? 

A. by using the AS-PATH attribute 

B. by using route tags 

C. by activating split horizon 

D. by implementing spanning tree 

Answer: B 

Q28. You have been hired to redesign a network due to issues with congestion. How will a router function if the QoS mechanism of congestion avoidance is integrated into the existing network design? 

A. the router handles the overflow of traffic by using FIFO B. the router handles the possible buildup of congestion by using WRED 

C. the router forces inbound and outbound traffic to stay within a defined profile by using rate limiting 

D. the router separates packets based on certain characteristics by using NBAR 

E. the router marks packets based on certain characteristics by using PBR 

Answer: B 

Q29. A network designer has provisioned a router to use IPsec to encrypt the traffic over a GRE tunnel going to a web server at a remote location. From the router, the network designer can ping the web server, although the users in the office comment that they are unable to reach it. (Note: The DF bit is not set.) Which aspect should be changed in the design of the virtual connection? 

A. IP addresses of the GRE tunnel endpoints 

B. IPsec configuration 

C. MTU size on the GRE tunnel 

D. encapsulation of the GRE tunnel 

Answer: C 

Q30. Refer to the exhibit. 

Assume that no multicast optimization is done on LAN switches A and B. Which feature can be used to optimize multicast traffic forwarding in this situation? 

A. Enable IGMP snooping querier on both switches. 

B. Configure a static MAC entry for the multicast server. 

C. Disable IGMP snooping on both switches. 

D. Disable the IGMP query election process. 

E. Enable PIM Snooping on both switches. 

Answer: A
