642-655 - WAASFE-Wide Area Application Services for Field Engineers
Go back to Cisco
You work as a network technician for your company. You are asked to configure a Central Manager WAE cluster for your customer. After the power cord is accidentally unplugged from the primary Central Manager WAE, the standby Central Manager WAE did not automatically assume the primary role. What should you do?
You must manually initiate failover and fallback processes on the WAE
Through which two ways firewalls can cause WAAS performance issues? (Choose two.)
Firewalls see that the TCP sequence number has shifted and drop the connection
Auto discovery uses the firewall scrub of the TCP options
The Cisco WAAS design for your customer calls for the Central Manager to be deployed on the Core WAE, which is a Cisco WAE-612 with 2-GB RAM. The customer initially configured the WAE as an application accelerator and then issued the device mode central-manger command to enable Central Manager Service. The customer reports that the WAE is no longer accelerating traffic. What is the problem?
Central Manager and Application Accelerator cannot be deployed on the same WAE
How do you obtain the client software for WAAS Mobile?
By creating a client distribution in the WAAS Mobile Manager
Which option below associates classified traffic to an application definition and assigns an action?
What is a valid Cisco WAAS device group type?
WAFS core cluster
Which command verifies that a WAE in-line card is intercepting traffic from the correct VLANs?
show int inlinegroup x/y
What two steps are necessary to enable virtualization on a WAVE? (Choose two.)
Enable the virtual blade.
Install the virtual-blade license.
At which point must a reload command be issued during initial setup of the Central Manager WAE?
After issuing the copy run start command
In order to enable load balancing across WAE interfaces, which WAE deployment model should be used to configure PortChannels on the core WAE appliances?
One of your customers is using firewalls. What need to be permitted to pass through firewalls in order to allow WAE autodiscovery?
In a Cisco WAAS deployment, what should you check first if your customer is reporting poor performance across all optimized applications?
Verify that (full) duplex settings is correctly configured on all interfaces
With Cisco WAAS, which two WCCPv2 service groups are used to make up the TCP Promiscuous service group? (Choose two.)
In which two ways will you register and activate a WAE to the Central Manager? (Choose two.)
The quickstart setup procedure
Which feature of Central Manager specifies the configuration items that a user can see?
Effective device permissions such as access and configure are the summations of which two elements? (Choose two.)
Roles assigned to that user
Domains assigned to that user
After configuring a Cisco WAAS deployment using WCCPv2, you find that you can successfully ping a data center sever from a workstation in the branch office however, when you attempt to start one of the optimized applications, the application cannot communicate with the server. What is the most likely cause?
You deployed the WAE on the same subnet as the users or servers
How to monitor optimization statistics for a given application across multiple WAE devices?
Create a device group for all WAE devices on which that application is optimized
Your customer has configured each Cisco WAE to belong to multiple device groups for monitoring purposes. However the customer wants to ensure that the policies are applied to the device from one specific device group. What should you do?
You should configure an explicit policy device group
In the WAAS mobile manager, what will you click to monitor current user connections?
Connections under Active Sessions
When must WCCPv2 redirect exclusion be configured on the routers?
When redirect out is used on any interface
Which WAAS mobile tool can be used to verify that data is moving between the client and the WAAS mobile server?
The Active Sessions Traffic screen
The Cisco WAE Appliances provide a unified platform for hosting Cisco application acceleration and WAN optimization solutions. Your customer complains that traffic has never been received by the remote WAE device after deploying Cisco WAAS by use of WCCPv2 in an off-path configuration. Which two parameters should be verified? (Choose two.)
Service group redirection
How do you access the WAE Central Manager GUI?
What will be displayed by the command show statistics connection all summary?
Which optimizations are applied to each connection
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 WAE device recently registered against a Central Manager. What must you do before the WAE can receive a policy and interact with other WAE devices?
Activate the device
Which setting should be used in the "Boot from" filed in the virtual blade configuration when an operating system is first installed through an CD ISO image onto a virtual blade?
Which three parameters are valid for a device group? (Choose three.)
Installed software version
How to configure authentication if your customer would like to use Active Directory to manage authentication for WAE administrative users?
Configure Windows domain as the primary login method in Central Manager
When configuring adapter policies in a Cisco WAAS environment, what is the purpose of the EPM adapter?
To identify the dynamically assigned port number of a connection
Cisco WAAS is a powerful application acceleration and WAN optimization solution that accelerates the performance of any TCP-based application delivered across a WAN. Which two benefits does the WAAS integration feature on the Cisco IOS Intrusion Prevention System and Cisco IOS Firewall allow? (Choose two.)
This WAAS feature supports TCP optimization used for distinguishing distant WAAS endpoints
This feature permits the sequence number jump initiated by Cisco WAAS
When a Cisco WAE that was optimizing connections fails, which two symptoms will appear in a TCP trace? (Choose two.)
The receiving node receives TCP segments with invalid sequence numbers and resets the connection.
All optimized TCP connections handled by that WAE are reset.
When managing a virtual blade through a Virtual Network Computing client, what does the address 10.10.10.10:1 represent?
The IP address of the physical interface the virtual interface is bound to on the WAE and the virtual blade number.
What is the function of Application Traffic Policies in a Cisco WAAS environment?
To associate a flow with an optimization and associate the optimized flow with an application definition
Your customer has recently completed a large expansion of one of their regional offices. They have discovered that the WAE-512-2GB Edge WAE in that office has begun passing through some TCP connections without optimizing those connections. What two actions would solve the problem? (Choose two.)
Upgrade to a WAE-612 or WAE-7326
Add another WAE-512 edge WAE
How can you configure a WAE to reboot after a software image has been installed?
Configure the WAE manually by using the "auto-reload" check box on the software files page
