Q1. A senior network designer suggests that you should improve network convergence times by reducing BGP timers between your CE router and the PE router of the service provider. Which three factors should you to consider when you adjust the timer values? (Choose three.)
A. access bandwidth
B. service provider agreement to support tuned timers
C. number of routes on the CE router
D. number of VRFs on the PE router
E. service provider scheduling of changes to the PE
Answer: ABC
Q2. In a large enterprise network with multiple data centers and thousands of access devices, OSPF is becoming unstable due to link flapping. The current design has the access devices multihomed to large aggregation routers at each of the data centers. How would you redesign the network to improve stability?
A. Add a layer of regional Layer 3 aggregation devices, but leave the ABR function on the data center aggregation routers.
B. Add a layer of regional Layer 2 aggregation devices, but leave the ABR function on the data center aggregation routers.
C. Add a layer of regional Layer 3 aggregation devices and move the ABR function to the regional aggregation device.
D. Add a layer of regional Layer 2 aggregation devices and move the ABR function to the regional aggregation device.
Answer: C
Q3. You have been tasked to create a Layer 2 network design that uses vPC to provide resiliency and avoid loops. vPC removes Layer 2 loops while providing redundancy through which mechanism?
A. dual-active detection
B. address synchronization
C. strict forwarding rules
D. Bridge Assurance
Answer: C
Q4. You are deploying a nationwide intranet solution for a company with 4 data centers and 400 remote branches connected via a provider-based solution. As part of the network design, you must ensure efficient content distribution of training material to remote sites. Which two VPN technologies leverage replication in the network core and provide for efficient bandwidth optimization? (Choose two.)
A. VPLS
B. EoMPLS
C. MPLS Layer 3 VPN
D. GRE
E. GET VPN
Answer: CE
Q5. Which option is a benefit of using N-Port Virtualization?
A. reduces the amount of domain IDs that are used in the fabric
B. does not need to create zoning
C. reduces latency when using local switching on Fibre Channel ports
D. allows trunking to the upstream switch
E. does not need to configure the upstream switches
Answer: A
Q6. 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
Q7. What are two benefits of following a structured hierarchical and modular design? (Choose two.)
A. Each component can be designed independently for its role.
B. Each component can be managed independently based on its role.
C. Each component can be funded by different organizations based on its role.
D. Each component can support multiple roles based on the requirements.
E. Each component can provide redundancy for applications and services.
Answer: AB
Q8. 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
Q9. 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
Q10. A company wants to use SSM as the multicast routing protocol inside its network. Some of its multicast applications do not support IGMPv3. In which two ways can the mapping be done when these applications send IGMPv2 join messages? (Choose two.)
A. The Layer 2 switches can send a request to a DNS server.
B. The Layer 3 multicast routers can send a request to a DNS server.
C. The mapping can be done statically at the Layer 2 switches.
D. The mapping can be done statically at the Layer 3 multicast routers.
E. The Layer 2 switches can transform the IGMPv2 join to an IGMPv3lite join.
F. The Layer 3 multicast routers can transform the IGMPv2 join to an IGMPv3lite join.
