   How is AppDynamics used to instrument an application?

   • AEnables instrumenting a backend web server for packet installation by using an AppDynamics agent.
   • BRetrieves a significant amount of information from the perspective of the database server by using application monitoring.
   • CProvides visibility into the transaction logs that can be correlated to specific business transaction requests.
   • DMonitors traffic flows by using an AppDynamics agent installed on a network infrastructure device.

   Show answer

   Answer: C

   Explanation

   C is correct. AppDynamics automatically discovers business transactions, both known and unknown. A business transaction is made up of all the required services within the environment that are called upon to fulfill and deliver a response to a user-initiated request. These are typically things like login, search, checkout, and so on, that will invoke various applications, web services, third-party APIs, and databases.

9. Question 159 · 385 in bank

   How does the use of release packaging allow dependencies to be effectively managed during deployments?

   • Aremoval of release units if they have issues in testing
   • Bdependencies are tested after the release is deployed
   • Cdesigned to prevent any dependencies between release units
   • Ddependencies are staggered between multiple releases

   Show answer

   Answer: C

   Explanation

   If the goal is to ensure strict isolation and minimize any interdependencies between release units, option C would be preferable. This approach promotes cleaner boundaries between units and simplifies the management and troubleshooting of the system. If the deployment scenario requires a more flexible approach, with the ability to independently manage and test dependencies while allowing for gradual rollouts, option D could be a better choice. This approach acknowledges that dependencies may exist but seeks to control their introduction and impact. Ultimately, the decision between option C and D should be based on factors such as the complexity of dependencies, the desired level of isolation, the deployment strategy, and the specific trade-offs and priorities of the project.

10. Question 160 · 385 in bank

    An application requires SSL certificates signed by an intermediate CA certificate. The .crt files must be available to the application: • The root CA certificate is root_certificate.crt. • The intermediate CA certificate is intermediate_certificate.crt. • The application-specific SSL certificate is crl_certificate.crt. Which Bash command outputs the certificate bundle as a .pem file?

    • Acat intermediate_certificate.crt root_certificate.crt > certificate_bundle.pem
    • Bcat crl certificate.crt intermediate certificate.crt root certificate.crt > certificate bundle.pem
    • Ccat root certificate.crt intermediate certificate.crt crl certificate.crt > certificate bundle.pem
    • Dcat root certificate.crt intermediate certificate.crt > certificate bundle.pem

    Show answer

    Answer: B

    Explanation

    RFC 5246 7.4.2 Server Certificate certificate_list This is a sequence (chain) of certificates. The sender's certificate MUST come first in the list. Each following certificate MUST directly certify the one preceding it. Because certificate validation requires that root keys be distributed independently, the self-signed certificate that specifies the root certificate authority MAY be omitted from the chain, under the assumption that the remote end must already possess it in order to validate it in any case. The same message type and structure will be used for the client's response to a certificate request message. Note that a client MAY send no certificates if it does not have an appropriate certificate to send in response to the server's authentication request.
