CCNP CHAP 2
What is true about TCAM lookups that are associated with CEF switching?
A single TCAM lookup provides Layer 2, Layer 3, and ACL information.
Which statement is true about the CEF forwarding process?
After an IP prefix match is made, the process determines the associated Layer 2 header rewrite information from the adjacency table.
Which layer 3 switching method used by Catalyst switches offers the greatest performance?
CEF
What is the purpose of the Cisco Enterprise Architecture and the hierarchical desgin?
Each element in the hierarchy has a specific set of functions and services that it offers and specific role.
Which family of Cisco switches is specifically designed for data centers?
Nexus 7000
Which two features are unavailable on a Layer 2 switch?
Time to Live (TTL) decrementing rewrite of the source and destination MAC addresses
Why does extending layer 3 switching to the access layer improve scalability?
VLANs are terminated on the access layer devices.
A user needs to access a file server that is located in another department. Which layer of the Cisco Hierarchical Network Model will process the traffic first?
access
At what layer of the hierarchical model are MAC-based security controls implemented?
access layer
Which portion of the enterprise network provides access to network communication services for the end users and devices that are spread over a single geographic location?
campus module
For what is the control plane on a catalyst switch responsible?
control of the routing protocols and processes running on the switch
In terms of design, which layer of the hierarchical model is the most complex?
distribution Layer
At what layer of the hierarchical design model would redistribution and summarization occur?
distribution layer
What are two responsibilities of devices that are located at the core layer of the hierarchical design model?
high-speed backbone switching interconnection of distribution layer devices
In its network design, a company lists this equipment : Two Catalyst 4503 Layer 3 switches One 5500 security appliance firewall Two Catalyst 6509 switches Two lightweight access points Two Catalyst 2960 switches Which two types of devices from the list would be appropriate to use at the access layer to provide end-user connectivity?
lightweight access points Catalyst 2960 switches
What feature of CEF allows for Layer 3 switches to use multiple paths?
load-balancing
What plane on a network device is accessed using SSH or SNMP?
management plane
What is the suggested solution for routing when Layer 3 routing is extended to the access layer?
run an IGP between the distribution and core layers and use static default routes at the access layer
A network designer must provide a rationale to a customer for a design that will move an enterprise from a flat network topology to a hierarchical network topology. Which two features of the hierarchical design make it the better choice?
scalability segmentation of broadcast domains
What type of specialized memory is used to facilitate high performance switching in Cisco multilayer switches?
ternary content addressable memory (TCAM)
