• Question 86:

  A Citrix Administrator needs to configure a rate limiting policy for the DNS requests to a threshold of 1000 DNS requests per second.

  Which set of commands does the administrator need to run to correctly configure the rate limiting policy?

  A. add stream selector DNSSelector1 client.udp.dns.domainadd ns limitIdentifier DNSLimitIdentifier1 – threshold 5 –timeSlice 1000 –selectorName DNSSelector1add dns policy DNSLimitPolicy1 “sys.check_limit(\”DNSLimitIdentifier1\”)” –preferredLocation “North America.US.TX.Dallas..”bind dns global DNSLimitPolicy1 5

  B. add stream selector DNSSelector1 client.udp.dns.domainadd ns limitIdentifier DNSLimitIdentifier1 – threshold 5 –timeSlice 1000 –selectorName DNSSelector1add dns policy DNSLimitPolicy1 “sys.check_limit(\”DNSLimitIdentifier1\”)” –preferredLocation “North America.US.TX.Dallas..”

  C. add stream selector DNSSelector1 client.udp.dns.domainadd ns limitIdentifier DNSLimitIdentifier1 – threshold 1000 –timeSlice 1000 –selectorName DNSSelector1add dns policy DNSLimitPolicy1 “sys.check_limit(\”DNSLimitIdentifier1\”)” –preferredLocation “North America.US.TX.Dallas..”

  Correct Answer: C

• Question 87:

  Scenario: A Citrix Administrator needs to implement a Content Filter policy to ensure the following conditions are met:

  The user with source IP 10.100.32.211 should NOT be allowed to access the vserver 10.10.10.1.

  All other users from subnet 10.100.32.0/24 should have access to the vserver 10.10.10.1.

  Access to the vserver should be blocked for all the other users.

  Which policy expression will meet this requirement if the policy action is RESET and the policy is bound to the server (VIP:10.10.10.1)?

  A. REQ.IP.SOURCEIP != 10.100.32.211 || REQ.IP.SOURCEIP != 10.100.32.211 –netmask 255.255.255.0

  B. REQ.IP.SOURCEIP = = 10.100.32.211 || REQ.IP.SOURCEIP != 10.100.32.0 –netmask 255.255.255.0

  C. REQ.IP.SOURCEIP != 10.100.32.211 andand REQ.IP.SOURCEIP = = 10.100.32.0 –netmask

  255.255.255.0

  D. REQ.IP.SOURCEIP = = 10.100.32.211 andand REQ.IP.SOURCEIP != 10.100.32.0 –netmask

  255.255.255.0

  Correct Answer: A

• Question 88:

  B. View the new nslog from the command-line interface (CLI) to look for packet resets from the NetScaler.

  C. Look in the Event Viewer for packet resets from the NetScaler.

  D. Use the nslog to look for packet resets on the NetScaler.

  Correct Answer: B
