Network Design and Management Quiz

What is the benefit of deploying Layer 3 QoS marking across an enterprise network?

• Layer 3 marking can carry the QoS information end-to-end.

• Layer 3 marking can be carried in the 802.1Q fields.

• Layer 3 marking can be used to carry non-IP traffic.

• Layer 3 marking can carry QoS information on switches that are not IP aware.

What network design would contain the scope of disruptions on a network should a failure occur?

• The deployment of distribution layer switches in pairs and the division of access layer switch connections between them.

• The configuration of all access layer devices to share a single gateway.

• The installation of only enterprise-class equipment throughout the network.

• The reduction in the number of redundant devices and connections in the network core.

Which statement describes SNMP operation?

• An SNMP agent that resides on a managed device collects information about the device and stores that information remotely in the MIB that is located on the NMS.

• An NMS periodically polls the SNMP agents that are residing on managed devices by using traps to query the devices for data.

• A set request is used by the NMS to change configuration variables in the agent device.

• A get request is used by the SNMP agent to query the device for data.

• A get request is used by the SNMP agent to query the device for data.

A network administrator configures a router with the command sequence:
R1(config)# boot system tftp://c1900-universalk9-mz.SPA.152-4.M3.bin

What is the effect of the command sequence?

• The router will load IOS from the TFTP server. If the image fails to load, it will load the IOS image from ROM.

• The router will copy the IOS image from the TFTP server and then reboot the system.

• On next reboot, the router will load the IOS image from ROM.

• The router will search and load a valid IOS image in the sequence of flash, TFTP, and ROM.

What component is considered the brains of the ACI architecture and translates application policies?

• The Application Policy Infrastructure Controller

• The hypervisor

• The Nexus 9000 switch

• The Application Network Profile endpoints

The software clock on a router or switch starts when the system boots. It is the primary source of time for the system.

• True

• False

Which term is used to describe a set of instructions for execution by the configuration management tool SaltStack?

• Manifest

• Cookbook

• Playbook

• Pillar

What is the principle that is applied when a network technician is troubleshooting a network fault by using the divide-and-conquer method?

• Once it is verified that a component in a particular layer is functioning properly, testing can then be performed on any other layer.

• Testing is performed at all layers of the OSI model until a non-functioning component is found.

• Once it is verified that components in a particular layer are functioning properly, it can then be assumed that components in the layers below it are also functional.

• Testing is performed at Layer 7 and at Layer 1, then at Layers 6 and 2, and so on, working towards the middle of the stack until all layers are verified as operational.

Creating a borderless switched network requires that sound network design principles are used to ensure maximum availability, flexibility, security, and manageability.

• True

• False
