Chapter 1: Enterprise Campus Architecture Flashcards
The Application Layer in SONA is what?
Business and collaboration applications; meet business requirements leveraging interactive services layer.
Security in the Access Layer in the Campus Architecture would feature what services?
Port security, DHCP snooping, Dynamic ARP inspection, IP source guard.
This area of the enterprise network was originally referred to as the server farm.
Data center
The following statement describes which part of the enterprise network that is generally understood to be the facility used to house computing systems and associated components and was original referred to as the server farm?
Data center
Which campus design element is proper high-availability (HA) characteristics result in near-100% uptime?
Resilient
Which campus design element easily supports growth and change. Scaling the network is eased by adding new modules in lieu of complete redesigns?
Modular
A Large Campus Sized network would have more than how many end devices?
2000 end devices.
Which campus design element allows change in business is a guarantee for any enterprise. These changes drive campus network requirements to adapt quickly?
Flexible
The Networked Infrastructure Layer in SONA is what?
Where all IT resources interconnect.
A Small Campus network would have less than how many end devices?
Less than 200
In the Data Center Infrastructure there is the Core and the Access layer, but the distribution layer is replaced by what?
Aggragation Layer
What are the three layers of SONA?
- Application layer
- Interactive services layer
- Networked infrastructure layer
Normal Data is considered to be what?
File and print services, email, Internet browsing, database access, shared network applications
Why are hierarchical designs used with layers as an approach to network design?
Simplification of large-scale designs and Reduce complexity of troubleshooting analysis.
ASIC-based (hardware) switching is supported even with ___ and ___, depending on the platform
QoS and ACLs
A Medium Sized Campus network would have between how many end devices?
200 to 1000 end devices.
Why are Layer 2 domains popular in data center designs?
Data centers place heavier emphasis on low-latency, whereas some applications operate at Layer 2 in an effort to reduce Layer 3 protocol overhead.
What is TCAM?
ternary content addressable memory
A small-sized campus network might combine which two layers of the hierarchical model?
Core and distribution
Signaling traffic and encapsulated voice traffic are classified as what type of traffic?
IP Telephony
SONA is an architectural framework that guides the evolution of _____?
Enterprise networks to intelligent network services
Name the three layers from Top to Bottom
- Core
- Distrubtion
- Access
IP/TV and market data applications are classified as what type of traffic?
IP Multicast
What is the Scavenger Class Traffic type?
All traffic with protocols or patterns that exceed normal data flows; less than best-effort traffic, such as peer-to-peer traffic.
Which layer in the Campus Architecture grants user access to network devices?
Building Access Layer
The Interactive Services Layer in SONA allows for what?
Enable efficient allocation of resources to applications and business processes through the networked infrastructure.
What is SONA?
Service-Oriented Network Architecture
In the Core Layer you need to implements scalable protocols and technologies such as?
Load Balancing
Where would a high-speed campus backbone be located in the Campus Architecture?
Building Core Layer

Which part of the enterprise network that is understood as the portion of the network infrastructure that provides access to services and resources to end users and devices that are spread over a single geographic location?
Campus
There are three key elements to the Access Layer in the Campus Architecture, what are they?
- High availability
- Convergence
Security
The Building Distribution Layer would use what to isolate network problems?
Aggregate wiring closets and use switches to segment workgroups.
BPDU, CDP, SNMP, RMON, SSH are examples of what type of traffic?
Network Management
