Scenario: A Citrix Administrator has configured the Citrix ADC as a DNS Proxy Server. The administrator executed the commands in the screenshot on the Citrix
ADC using the command-line interface.
Click on the 'Exhibit' button to view the screenshot of the command-line interface.
What will be the effect of this configuration?
The configuration commands shown in the screenshot are using Citrix ADC to create a DNS Proxy Server with specified responder policies and actions. The responder action 'Act_1' creates a new DNS response with the 'TC' (Truncation) bit set to true, meaning the DNS response is indicating that the message is truncated and should be retried via TCP, and the 'rcode' is set to NOERROR, indicating no error in the DNS response. The responder policy 'Pol_1' specifies that this action should apply to DNS requests using UDP. Given this, the configuration will create a DNS Response with the 'TC' bit set and the 'rcode' as NOERROR. Therefore, the correct answer is that the configuration will create a DNS Response with the 'TC' bit set and 'rcode' as NOERROR.
B is correct Read doc in link provided by Happiman To enforce all the DNS requests over TCP, create a responder action that will set the TC bit and rcode as NOERROR. > add responder action resp_act_set_tc_bit respondwith DNS.NEW_RESPONSE(true, true, NOERROR) Done > add responder policy enforce_tcp dns.REQ.TRANSPORT.EQ(udp) resp_act_set_tc_bit Done >bind lb vserver dns_udp –policyName enforce_tcp -type request –priority 100 Done
I dont think these are 1Y0-204 exam question , can anyone who has passed this exam conform it
