What are three key design principles when using a classic hierarchical network model? (Choose three.)
What are three key design principles when using a classic hierarchical network model? (Choose three.)A . The core layer controls access to resources for security.B . The core layer should be configured with minimal complexity.C . The core layer is designed first, followed by the distribution layer and then the...
Which one of these addresses would the ACL need for traffic sourced from the inside interface, to match the source address of the traffic?
Your network operations team is deploying Access Control Lists (ACLs) across your Internet gateways. They wish to place an ACL inbound on the Internet gateway interface facing the core network (the "trusted" interface). Which one of these addresses would the ACL need for traffic sourced from the inside interface, to...
Which mechanism should be added to a network design to identify unidirectional Spanning Tree Protocol failures through BPDU loss?
Which mechanism should be added to a network design to identify unidirectional Spanning Tree Protocol failures through BPDU loss?A . UDLDB . loop guardC . BPDU guard?D . root guardView AnswerAnswer: B
In an MPLS-VPN environment, what is the effect of configuring an identical set of route targets for a particular VRF, but then configuring nonidentical route distinguisher across multiple PE devices?
In an MPLS-VPN environment, what is the effect of configuring an identical set of route targets for a particular VRF, but then configuring nonidentical route distinguisher across multiple PE devices?A . The routes will be correctly handled by the control plane, but there will be instances where routes take up...
What impact will their choice have on the existing multicast design?
A new video multicast application is deployed in the network. The application team wants to use the 239.0.0.1 multicast group to stream the video to users. They want to know if this choice will impact the existing multicast design. What impact will their choice have on the existing multicast design?A...
Which two design solutions can be applied to ensure that your access routers will be able to reach all devices in your network?
You work as a network designer for a company that is replacing their Frame Relay WAN with an MPLS VPN service, where the PE-to-CE routing protocol is BGP. The company has 3000 routes in their distribution routers, and they would like to advertise their access routers through the MPLS network....
On a VoIP solution design, which option shows one-way latency, packet loss, and jitter measurements that ensure acceptable voice quality?
On a VoIP solution design, which option shows one-way latency, packet loss, and jitter measurements that ensure acceptable voice quality?A . Latency: 110 ms Packet loss: 1% Jitter: 40 msB . Latency: 130 ms Packet loss: 0.5% Jitter: 30 msC . Latency: 150 ms Packet loss: 1.25% Jitter: 20 msD...
Which two design considerations should be implemented for the pseudowires between the N-PE and U-PE routers?
Refer to the exhibit. You are designing a loop-free hierarchical VPLS service. Which two design considerations should be implemented for the pseudowires between the N-PE and U-PE routers? (Choose two.)A . Disable split horizon toward the N-PE routers.B . Disable split horizon toward the U-PE router.C . Enable split horizon...
Which two of these options would result in a trouble-free spanning-tree network design?
Refer to the exhibit. You are designing a spanning-tree network for a small campus. Which two of these options would result in a trouble-free spanning-tree network design? (Choose two.)A . Convert all ports to trunk ports, prune off the VLANs that you do not require, and minimize the number of...
From a design perspective, what was not taken into account prior to implementing the solution?
After the recent implementation of a new design that incorporated GRE tunnels into the network, the network operations staff is seeing the following syslog message in multiple routers on the network - %TUN-5-RECURDOWN: Tunnel0 temporarily disabled due to recursive routing. From a design perspective, what was not taken into account...
