- Cisco Collaboration Architecture
- Cisco Enterprise Campus Architecture
- Cisco Enterprise Branch Architecture
- Cisco Enterprise Data Center Architecture
- Cisco Borderless Network Architecture

At which layer of the hierarchical network model do users connect to the network?
Which two statements regarding the Cisco AnyConnect software are true? (Choose two.)
- It is part of the borderless end-point/user services.
- It is part of the borderless network services.
- It is used to connect any device to the network.
- It is used to connect from anywhere.
- It is used to connect without an Internet connection.
- It is used to establish a secure, persistent, policy-based connection.
Which three devices are found in the access layer of the hierarchical network model? (Choose three.)
- Firewall appliance
- Layer 2 switch
- Layer 3 switch
- Modular multilayer switch
- VoIP phones
- Wireless access point
Which two statements correctly describe a collapsed core network design? (Choose two.)
- Also called a two-tier hierarchical network design
- Also called a three-tier hierarchical network design
- Consists of the access layer and distribution layer in one device
- Consists of the access layer and core layer in one device
- Consists of the distribution and core layer in one device
Which goal can be accomplished by implementing the Cisco enterprise teleworker module?
- It allows the enterprise to add large branch sites that span geographic areas.
- It allows the enterprise to deliver secure voice and data services to workers no matter where or when they work.
- To reduce remote security threats, it forces users who are located at main sites to log on to resources.
- It satisfies telephony requirements for users who are located at medium to large enterprise sites.
What should be considered first when starting the network design?
- Connectivity to the data center
- Connectivity to the branch site
- Protocols required
- Size of the network
- Type of security implemented
- Type of applications
Which network architecture functions through a combination of technologies that include wired, wireless, security, and more?
- Cisco Borderless Network
- Cisco Enterprise Branch
- Cisco Enterprise Campus
- Cisco Enterprise Edge
- Cisco Enterprise Teleworker
What does the application and device layer of the Cisco Collaboration Architecture do?
- It contains applications such as Cisco WebEx Meetings, Cisco Jabber, and TelePresence to help users stay connected and productive.
- It is responsible for allowing collaboration anytime, from anywhere, on any device.
- It supports collaboration applications with presence, location, session management, contact management, client frameworks, tagging, and policy and security management.
