Cisco 642-655 Exam Syllabus Topics:

Cisco WAASFE-Wide Area Application Services for Field Engineers Sample Questions:

1. Your customer plans to implement Cisco WAAS using four WAE appliances in a load-balanced configuration. Which feature must be supported on the switches to which the WAE appliances are attached?

A) Layer 2 Redirection
B) WCCPv2
C) Redirect exclusion
D) WCCPv2 or PBR

2. With Cisco WAAS, which two WCCPv2 service groups are used to make up the TCP Promiscuous service group? (Choose two.)

A) 61
B) 89
C) 60
D) 62

3. Exhibit:

Your customer plans to deploy the edge WAE appliances in an off-path, two-arm configuration. The WAE appliances are connected to Cisco Catalyst 6500 Series Switches and use WCCPv2 for traffic interception. The customer wants to minimize the latency added by interception. The customer also wants to know if Layer 2 redirection, rather than GRE tunnels, will improve performance.
What should you tell your customer?

A) GRE tunnels provide better performance than Layer 2 redirection
B) Layer 2 redirection can be used only in in-path configurations
C) Layer 2 redirection can be used in the customer configurations
D) Layer 2 redirection can be used only in one-arm configurations

4. What is the function of Application Traffic Policies in a Cisco WAAS environment?

A) To associate a flow with a WAE and associate the optimized flow with a device group
B) To associate a flow with a WAN connection and associate the WAN connection with an application accelerator
C) To associate a flow with an optimization and associate the optimized flow with an application definition
D) To associate a flow with a Central Manager and associate the optimized flow with an application definition

5. Exhibit: The exhibit shows an entry from a TFO transaction log on the WAE. What conclusion can you draw from this result?

A) The connection is not being optimized because the configured optimizations are not supported on the peer WAE
B) The connection is not being optimized because the remote WAE had different TFO optimizations configured than the local WAE
C) The connection is being optimized correctly, but no traffic has been optimized yet
D) The connection is not being optimized because autodiscovery failed with the remote WAE
