Question 4.
You are establishing a policy to measure the effectiveness of your deployment process.
You decide to track one or more phases of development to identify defects. Which phase or phases should you track?(Choose all that apply)
A. Design and analysis
B. Development
C. Stabilization
D. Requirements
Answer: C
Explanation:
C: It is during the stabilizing phase that the Testing team completes the tasks and creates the deliverables that move the feature-complete build to a state in which the defined quality level is reached and the solution is ready for full production deployment.
The two main tasks in the stabilizing phase are:
• Testing the solution: The team implements the test plans that were created during the planning phase, which were enhanced and tested during the development phase.
• Conducting the pilot: The team moves a solution pilot from development to a staging area to test the solution with actual users and real scenarios. The pilot is conducted before the deploying phase is begun.
A pilot is a test of the solution in the production environment, and a trial of the solution by installers, systems support staff, and end users. The primary purposes of a pilot are to demonstrate that the design works in the production environment as expected and that it meets the organization’s business requirements. A secondary purpose is to give the deployment team a chance to practice and refine the deployment process.

Page 2-4 of BIG-IP Essentials v9 Student Guide
Question 7.
A site has six members in a pool. All of the servers have been designed, built, and configured with the same applications. It is known that each client's interactions vary significantly and can affect the performance of the servers.
If traffic should be sent to all members on a regular basis, which load-balancing method is effective if the goal is to maintain a relatively event load across all servers?
A. Priority
B. Observed
C. Round Robin
D. Ration Member
Answer: B
Priority is not a load balancing method. Observed is the best answer, since round robin and ratio load balance without regard to system performance.
Page 2-10 of BIG-IP Essentials v9 Student Guide
Question 8.
Which statement accurately describes the relation between the two load-balancing modes specified as "member" and "node"?
A. There is no difference; the two terms are referenced for backward compatibility purposes.
B. When the load-balancing choice references "node", priority group activation is unavailable.
C. Load-balancing options referencing "nodes" are available only when the pool members are
defined for the "any" port.
D. When the load-balancing choice references "node', the address' parameters are used to make
the load-balancing choice rather than the member's parameters.
Answer: D
Nodes have only an IP address and may represent multiple pool members while pool members always have an IP address and service port designation.
