Q1. Which of the following three options represents the components of the Teleworker Solution? (Choose three.)
A. Cisco Unified IP Phone
B. Cisco 880 Series Router
C. Aironet Office Extend Access Point
D. Catalyst 3560 Series Switch
E. Cisco 2900 Series Router
F. MPLS Layer 3 VPN
G. Leased lines
Answer: A,B,E
Explanation:
A Cisco ASR is used to terminate Teleworker solutions, not a 2900 series router. Hybrid teleworker uses Aironet, Advanced teleworker uses 880, both use IP phones. google: "at_a_glance_c45-652500.pdf" for details
The Cisco Virtual Office Solution for the Enterprise Teleworker is implemented using the Cisco 800 series ISRs. Each ISR has integrated switch ports that then connect to the user’s broadband connection. The solution uses a permanent always-on IPsec VPN tunnel back to the corporate network. This architecture provides for centralized IT security management, corporate-pushed security policies, and integrated identity services. In addition, this solution supports the enterprise teleworker needs through advanced applications such as voice and video. For example, the enterprise teleworker can take advantage of toll bypass, voicemail, and advanced IP phone features not available in the PSTN.
Enterprise Teleworker Module
The enterprise teleworker module consists of a small office or a mobile user who needs to access services of the enterprise campus. As shown in Figure 2-14, mobile users connect from their homes, hotels, or other locations using dialup or Internet access lines. VPN clients are used to allow mobile users to securely access enterprise applications. The Cisco Virtual Office solution provides a solution for teleworkers that is centrally managed using small integrated service routers (ISR) in the VPN solution. IP phone capabilities are also provided in the Cisco Virtual Office solution, providing corporate voice services for mobile users.

Q5. Which one of these statements describes why, from a design perspective, a managed VPN approach for enterprise teleworkers is most effective?
A. A managed VPN solution uses a cost-effective, on-demand VPN tunnel back to the enterprise.
B. This solution supports all teleworkers who do not require voice or video.
C. This architecture provides centralized management where the enterprise can apply security policies and push configurations.
D. It provides complete flexibility for remote access through a wireless hotspot or a guest network at a hotel, in addition to a home office.
Answer: C
