SOA Fundamental SOA Security: Common Questions From Candidates

What is the SOA Fundamental SOA Security certification exam?

The SOA Fundamental SOA Security exam (code: S90.18) is the official SOA exam that leads to the SOA Certification certification. It sits at the Specialist level of the SOA certification track. It is also connected with related credentials such as SOA Security Specialist, SOACP - SOA Security Certification Path. Passing it proves to employers that your skills have been validated by SOA itself, which is why the S90.18 credential keeps showing up in job postings.

How many questions are in the S90.18 exam, and how long does it take?

The SOA Fundamental SOA Security exam gives you 60 minutes to work through 40. Pacing matters more than most candidates expect, so before exam day, run at least one full timed session in the Dumpkiller test engine to learn how long you can afford per question. If an item stalls you, flag it and move on — coming back later beats burning five minutes on a single question.

What score do I need to pass the S90.18 exam, and how much does it cost?

The passing score for the SOA Fundamental SOA Security exam is 70%, and the official registration fee is USD $125.

SOA Fundamental SOA Security Sample Questions:

Question 1

The messages exchanged between two services are kept confidential by using symmetric
encryption. The security specialist is quite strict about making sure that no attacker is able
to intercept and decipher messages sent between these two services. As a result, periodic
audits are conducted in order to ensure that shared keys are always kept confidential. A
single shared key has been in use for quite some time now. The security specialist was
confident that all keys were well guarded, but just recently their security was compromised.
How is this possible given that the shared key was never lost?

A. Symmetric encryption is not intended for long-term use. It needs to be replaced with
asymmetric encryption after some time.
B. The attackers somehow figured out which encryption algorithm was used. As a result,
they were able to decipher the messages.
C. Because the same shared key was used for a long time, attackers were able to obtain
the key by comparing messages sent between the two services.
D. The shared key was decoded by the attackers using algorithms from related private
keys used during prior message exchanges.

Question 2

The Data Confidentiality pattern can be applied using which of the following security
mechanisms?

A. asymmetric encryption
B. hashing
C. identity store
D. symmetric encryption

Question 3

When establishing a single sign-on mechanism, the application of the Standardized Service
Contract principle requires the use of SAML because it is an industry standard understood
by multiple service consumers.

A. True
B. False

Question 4

The communication between Service A and Service B needs to be kept private. A security
specialist is planning to implement secret key cryptography in order to encrypt the
messages. Which of the following approaches addresses this requirement?

A. Create a shared key that will be used by both the services for message encryption and
decryption.
B. None of the above.
C. Both the services need to be built with support for the XML-Signature industry standard.
D. The Data Origin Authentication pattern needs to be applied across both service
architectures.

Question 5

Security policies that extend the technical service contract must be standardized within a
given service inventory. This statement is in accordance with which service-orientation
principle?

A. None of the above
B. Service Reusability
C. Service Abstraction
D. Service Composability
