Q: 18

Scenario: A Citrix Administrator observes that when the client gets redirected to www.citrix.com/owa/search?q=username, an HTTP 503 response is received from the content switching vServer. The relevant configuration is as follows: > add cs action CS_Act_1 -targetLBVserver SERVER_1 > add cs action CS_Act_2 -targetLBVserver SERVER_2 > add cs action CS_Act_3 -targetLBVserver SERVER_3 > add cs action CS_Act_4 -targetLBVserver SERVER_4 > add cs policy CS_Pol_1 -rule "http.REQ.URL path_and_queryCONTAINS(\"connect\")" -action CS_Act_1 > add cs policy CS_Pol_2 -rule "http.REQ.URL path_and_query EQ(\"owa\")" -action CS_Act_2 > add cs policy CS_Pol_3 -rule "http REQ.URL path_and_query CONTAINS(\"owa\")" -action CS_Act_3 > add cs policy CS_Pol_4 -rule "http.REQ.IS_VALID" -action CS_Act_4 > bind cs vServer CS_vserver1 -policyName CS_Pol_1 -priority 110 > bind cs vServer CS_vserver1 -policyName CS_Pol_4 -priority 120 How can the administrator correct the issue?

Options

Correct Answer:

Explanation

The HTTP 503 error indicates the request was forwarded to a backend service that is unavailable. The request URL /owa/search?q=username is evaluated against the bound policies in priority order (lower number is higher priority).

1. CSPol1 (priority 110) is evaluated first. Its rule CONTAINS("connect") does not match the URL.

2. CSPol4 (priority 120) is evaluated next. Its rule http.REQ.ISVALID matches any valid HTTP request. The traffic is sent to SERVER4, which is unavailable, causing the 503 error.

To fix this, the traffic must be routed to the correct OWA server (SERVER3). CSPol3 uses the rule CONTAINS("owa"), which correctly matches the URL. Binding CSPol3 with a priority of 100 ensures it is evaluated before the other policies, correctly routing the traffic.

Why Incorrect

A. Unbinding CSPol1 would not change the outcome, as the request would still be matched by CSPol4 and sent to the unavailable server.

C. Binding CSPol2 would not work because its rule EQ("owa") requires an exact match and will not match the longer URL /owa/search?q=username.

D. Unbinding CSPol4 would result in no policy matching the request, causing the Citrix ADC to drop the connection, which is not the desired outcome.

"Content switching policies": This document explains that policies bound to a content switching virtual server are evaluated based on the priority number assigned to them

with the lowest number indicating the highest priority. The first policy that matches the request is applied. This supports the analysis that a new policy must be bound with a higher priority (lower number) to be evaluated first.

"Default syntax policies and expressions": This section details the syntax for policy expressions. It clarifies the difference between operators like CONTAINS (checks for a substring) and EQ (checks for an exact match). This confirms that CONTAINS("owa") is the correct operator for the given URL

while EQ("owa") would fail.
