Citrix ADC 13 Advanced Topics – Security, Management and Optimization — Question 4

Scenario:
POLICY 1:
add rewrite action ACT_1 corrupt_http_header Accept-Encoding
add rewrite policy POL_1 HTTP.REQ.IS_VALID ACT_1
POLICY 2:
add rewrite action ACT_2 insert_http_header Accept-Encoding `\`identity\`` add rewrite policy POL_2 `HTTP.REQ.IS_VALID ` ACT_2
How can a Citrix Administrator successfully bind the above rewrite policies to the load-balancing vServer lb_vsrv so that POL_2 is evaluated after POL_1 is evaluated?

Answer options

• A. bind lb vServer lb_vsrv -policyName POL_1 -priority 110 -gotoPriorityExpression NEXT -type REQUEST bind lb vServer lb_vsrv -policyName POL_2 -priority 100 -gotoPriorityExpression END -type REQUEST
• B. bind lb vServer lb_vsrv -policyName POL_1 -priority 90 -gotoPriorityExpression NEXT -type REQUEST bind lb vServer lb_vsrv -policyName POL_2 -priority 100 -gotoPriorityExpression END -type REQUEST
• C. bind lb vServer lb_vsrv -policyName POL_1 -priority 90 -gotoPriorityExpression END -type REQUEST bind lb vServer lb_vsrv -policyName POL_2 -priority 80 -gotoPriorityExpression NEXT -type REQUEST
• D. bind lb vServer lb_vsrv -policyName POL_1 -priority 90 -type REQUEST bind lb vServer lb_vsrv -policyName POL_2 -priority 100 -type REQUEST

Correct answer: B

Explanation

The correct answer is B because it sets POL_1 with a priority that allows it to be evaluated before POL_2, ensuring the correct sequence. The other options either have incorrect priorities or goto expressions that disrupt the intended evaluation order, preventing POL_2 from being processed after POL_1.
