DTrace is being ported from Solaris to Oracle Linux. Which three statements are true for the DTrace tool?

Question

Options

• ADTrace allows static and dynamic tracing of your applications and your kernel.
• BDTrace tool is used to compile debug kernel modules and device drivers
• CDTrace allows you to dynamically define probe points on the fly.
• DDTrace probes and probe points are usually defined by the user using scripts written in a
• EDTrace tool is based on the strace Linux tool and includes both user and kernel strace features.

• A
  70% (26)
• B
  19% (7)
• E
  11% (4)

Explanation

A:DTrace is a comprehensive dynamic tracing framework created by Sun Microsystems for troubleshooting kernel and application problems on production systems in real time. C:Key benefits and features of DTrace on Oracle Linux include: /Designed to work on finding performance bottlenecks /(C)Dynamically enables the kernel with a number of probe points, improving ability to service software /Enables maximum resource utilization and application performance /Fast and easy to use, even on complex systems with multiple layers of software D:Testers write tracing programs (also referred to as scripts) using the D programming language (not to be confused with other programming languages named "D"). The language, a subset of C, includes added functions and variables specific to tracing. D programs resemble awk programs in structure; they consist of a list of one or more probes (instrumentation points), and each probe is associated with an action. These probes are comparable to a pointcut in aspect-oriented
