Your company wants to limit bandwidth for Skype traffic. You have been tasked to configure Application Detection and Control using the Cisco ASR 5000 to detect Skype traffic for all subscribers. If Skype traffic is detected, limit the uplink and downlink data rate to 32 kb/s. Which required configuration is needed to complete this task?

What is the standard Subsystem Number for the Gf interface in the UMTS domain?
A. 6
B. 7
C. 8
D. 9
Which interface in the UMTS doamin uses the BSSAP+ layer?
A. Gs
B. Gr
C. Ge

Into which state does a UE in a GPRS network move after the ready timer expires?
A. idle state
B. detached state
C. suspended state
D. ready state
E. standby state
Which option describes the message that establishes the direct tunnel between RNC and GGSN?
A. SGSN context request/response and modify PDP context request/response
B. SGSN: Initiated update PDP context request/response and RAB assignment request/response
C. GGSN: Initiated update PDP context request/response and RAB assignment request/response
D. SGSN: Initiated update PDP context request/response and modify PDP context request/response
Which two nodes are introduced as part of UMTS as defined by 3GPP standards? (Choose two.)
A. SGSN

Which statement describes HTTP header enrichment and its uses?
A. HTTP header enrichment allows the operator to define a policy that inserts x-header fields into HTTP POST or GET request packets to provide specific subscriber information such as IMSI or MSISDN to the HTTP server without changing the protocol.
B. HTTP header enrichment is the process that allows HTTP headers to be compressed for optimal transfer across the network.
C. HTTP header enrichment allows the operator to define a policy that detects the HTTP packet that requires header enrichment. If a match occurs, the policy drops the packet, modifies the packet inline with quality of service definitions, or creates a log message and forwards the packet unmodified.
D. HTTP header enrichment is the process in which a HTTP packet is analyzed for missing or partial header fields. If missing fields are detected or incomplete, the Cisco ASR 5000 can then take action to insert a new header, repair an existing header, create a log entry, and forward the packet.
Which option describes how DNS snooping is used on the Cisco ASR 5000?
A. DNS snooping allows the Cisco ASR 5000 to snoop DNS query packets and compare against known DNS responses. If a match is found, the Cisco ASR 5000 replies to the query itself instead of forwarding the query to the destination DNS server.
B. DNS snooping allows the Cisco ASR 5000 to detect if a DNS response sent back to a subscriber is valid. If the response is invalid, the Cisco ASR 5000 drops the packet.
C. DNS snooping allows the Cisco ASR 5000 to enable set of dynamic IP rules to be installed based on the response to DNS queries sent by a subscriber that matches a configured domain rule definition. Dynamic IP rules are created for these IP entries within the same rule that has the domain name, which applies the same charging action to these dynamic rules.
D. DNS snooping allows the Cisco ASR 5000 to enable set of dynamic domain rules to be installed based on the response to DNS queries sent by a subscriber that matches a configured domain rule definition. Dynamic domain rules are created for the DNS responses within the same rule that has the domain name, which applies the same charging action to these dynamic rules.
