NO.4 Service A's logic has been implemented using managed code. An attacker sends an XML bomb to
Service A. As a result, Service A's memory consumption started increasing at an alarming rate and then
decreased back to normal. The service was not affected by this attack and quickly recovered. Which of
the following attacks were potentially avoided?
A. XML parser attack
B. Buffer overrun attack
C. Insufficient authorization attack
D. Denial of service
Answer: A,D

NO.5 The Trusted Subsystem pattern is applied to a service that provides access to a database. Select the
answer that best explains why this service is still at risk of being subjected to an insufficient authorization
attack.
A. Attackers can steal confidential data by monitoring the network traffic that occurs between the service
and the database.
B. Because the Service Perimeter Guard pattern was also not applied, the database is not protected by a
firewall.
C. If an attacker gains access to the security credentials used by the service to access the database, the
attacker can access the database directly.
D. None of the above.

NO.8 How can the use of pre-compiled XPath expressions help avoid attacks?
A. Pre-compiled XPath expressions execute faster and therefore help avoid denial of service attacks.
B. Pre-compiled XPath expressions reduce the chance of missing escape characters, which helps avoid
XPath injection attacks
C. Pre-compiled XPath expressions contain no white space, which helps avoid buffer overrun attacks
D. They can't because XPath expressions cannot be pre-compiled
Answer: B

NO.9 Service A has recently been the victim of XPath injection attacks. Messages sent between Service A
and Service C have traditionally been protected via transport-layer security. A redesign of the service
composition architecture introduces Service B, which is positioned as an intermediary service between
Service A and Service C. The Message Screening pattern was applied to the design of Service B. As part
of the new service composition architecture, transport-layer security is replaced with message-layer
security for all services, but Service A and Service C continue to share the same encryption key. After the
new service composition goes live, Service A continues to be subjected to XPath injection attacks. What
is the reason for this?
A. The message screening logic can only work for Service C. Therefore, Service A is not protected.
B. Because message-layer security is being used, it is not possible for the message screening logic in
Service B to inspect messages without having the encryption key that is shared by Service A and Service
C.
C. XPath injection attacks are not prevented by message screening logic or message-layer security.
D. None of the above.
Answer: B

NO.10 Service A needs to be designed so that it supports message integrity and so that only part of the
messages exchanged by the service are encrypted. You are asked to create the security policy for this
service. What type of policy assertions should you use?
A. Token assertions
B. Protection assertions
C. Security binding assertions
D. Service A's security requirements cannot be expressed in a policy
Answer: B

NO.13 The Service Perimeter Guard pattern has been applied to help avoid denial of service attacks for a
service inventory. As a result, services within the service inventory are only accessible via a perimeter
service However, denial of service attacks continue to succeed and services within the service inventory
become unavailable to external service consumers. What is the likely cause of this?
A. The application of the Service Perimeter Guard pattern needs to be combined with the application of
the Message Screening pattern in order to mitigate denial of service attacks.
B. The perimeter service itself is the victim of denial of service attacks. As a result, none of the services
inside the service inventory can be accessed by external service consumers.
C. The Trusted Subsystem pattern should have been applied so that each service has a dedicated trusted
subsystem.
D. The Service Perimeter Guard pattern does not help avoid denial of service attacks.
