A service provider is hosting a customer's servers. Users are complaining about slow response times. A customer wants a warning when the application starts to slow down. What can be done to notify the customer automatically when the slowdown starts?
enable Access-Link Monitoring
activate Response Time Measurement on the application class and set SLA
configure and register an event for the measurement variable for the application class
Click the Exhibit button. Wholesale Distributors has an IP WAN connecting three remote
distribution plants with five users each to corporate headquarters. All of these remote plants use only a web-based shipping/receiving application and a client server inventory control application located at headquarters. Remote plants A and B are having performance issues with both applications across their smaller WAN connections. Remote plant C has no performance problems. More WAN capacity at remotes plants A and B would help, but upgrading bandwidth at these sites is cost prohibitive due to geography. Assuming there is no remote-to-remote communications, which PacketShaper deployment would increase link thoughput and improve the performance of these applications for remote plants A and B?
one PacketShaper Xpress 1550 at remote plants A and B
one PacketShaper 2500 at headquarters and one PacketShaper Xpress 1550 at each remote plant
one PacketShaper Xpress 2500 at headquarters and one PacketShaper 1500 at remote plants A and B
one PacketShaper Xpress 1550 at remote plants A and B and one PacketShaper Xpress 2500 at headquarters
Which statement is true of the Top 10 Pie Chart on the Network Performance Summary page?
You can use it only if you have Easy Configure on.
It may not list applications that sporadically consume all of the WAN link for short bursts of time.
If you want the average rate and % values to be updated for a given class, you must click the class name in the pie chart.
It lists the top 10 application classes but not IP address-based classes because it helps you identify aggressive applications, not aggressive hosts or networks.
Which report from the PacketShaper may indicate a network congestion problem?
In the Top10 chart, HTTP shows almost 100% for the last hour.
The Network Efficiency graph is consistently showing over 98%.
The Normalized Network Delay graph shows a notable increase in transaction times.
Peak Utilization bps graph shows peaks of over half of the bandwidth of a 128 Kbps link.
The Normalized Network Delay for a particular class is steadily increasing but the Server Delay remains constant. What does this indicate?
The number of users is steadily increasing.
The application server is responding more slowly.
The amount of data being transferred during each transaction is increasing.
It is taking longer to transfer application data irrespective of the size of the transactions.
Which two statements are true when considering Guaranteed Rate Failures (GRF)? (Choose two.)
GRFs do not necessarily indicate link congestion.
If a flow is not allocated any bandwidth, then a GRF will be generated.
Increasing the Burst Limit of a partition should reduce the ooccurrences of GRFs.
If a partition limit is reached and no more bandwidth is available before Priority 3 policies are
satisfied, each Priority 3 flow will generate a GRF.
A class is showing regular GRFs. Creating a partition with a minimum size, or increasing the
size of its existing partition, should reduce the occurrences of GRFs.
PacketShaper Outbound Top10 graph shows 38% of the Outbound traffic is classified in the
Outbound/Default class. Traffic Discovery is on and the PacketShaper has been running for one week. Which three features/commands would you use to assist in further classifying the traffic? (Choose three.)
traffic history recent /outbound/default
traffic flow upIc /outbound/default
measure dump class outbound/default by time 1w 1m bytes pkts
Which three statements are true about the Compression Summary report? (Choose three.)
The Bytes Saved line shows the number of bytes that did not have to traverse the link, due to compression.
The Precompression Bytes line represents the number of bytes that would have passed through
the link if compression was not enabled.
The Non-compressible Bytes line shows the number of bytes that PacketWise tried to
compress but failed because of an Authentication failure.
The Postcompression Bytes line shows the number of bytes that actually passed through the
link (includes compressed and non-compressible bytes).
Click the Exhibit button. The information on the graph (which is for an HTTP class) can be directly used to indicate the required control settings for .

A company has a PacketShaper deployed on its WAN with the Outside interface directly connected to the WAN router. Remote locations access a PeopleSoft application server located on the inside of the PacketShaper. Recently, users have complained about performance for this application. You decide to run some Response Time Monitoring (RTM) reports on the Outbound/PeopleSoft traffic class for the previous day. However, when you try to run the reports, you get a message that Response Time statistics have been cleared and no new transactions have occurred. What is a possible cause for this?
You have not enabled RTM on your PacketShaper.
PacketShaper only holds on to RTM data for 1 hour.
PacketShaper only reports RTM statistics in the client-to-server direction.
You have not configured a delay threshold, therefore, no RTM statistics are being kept.
