考试内容：

Describe Cisco VoIP implementations.

• Describe the functions and operations of a VoIP network (e.g., packetization, bandwidth considerations, CAC, etc.).
• Describe and identify basic voice components in an enterprise network (e.g. Gatekeepers, Gateways, etc.)

Describe QoS considerations.

• Explain the necessity of QoS in converged networks (e.g., bandwidth, delay, loss, etc.).
• Describe strategies for QoS implementations (e.g. QoS Policy, QoS Models, etc.).

Describe DiffServ QoS implementations.

• Describe classification and marking (e.g., CoS, ToS, IP Precedence, DSCP, etc.).
• Describe and configure NBAR for classification.
• Explain congestion management and avoidance mechanisms (e.g., FIFO, PQ, WRR, WRED, etc.).
• Describe traffic policing and traffic shaping (i.e., traffic conditioners).
• Describe Control Plane Policing.
• Describe WAN link efficiency mechanisms (e.g., Payload/Header Compression, MLP with interleaving, etc.).
• Describe and configure QoS Pre-Classify.

Implement AutoQoS.

• Explain the functions and operations of AutoQoS.
• Describe the SDM QoS Wizard.
• Configure, verify, and torubleshoot AutoQoS implementations (i.e., MQC).

Implement WLAN security and management.

• Describe and Configure wireless security on Cisco Clients and APs (e.g., SSID, WEP, LEAP, etc.).
• Describe basic wireless management (e.g., WLSE and WCS). Configure and verify basic WCS configuration (i.e., login, add/review controller/AP status, security, and import/review maps).
• Describe and configure WLAN QoS.
