Answer(s): D
Explanation:
When I have a device that is acting up, I tend to run: ethtool ethX, check the
Supported link modes, the Link partner advertised link modes and the actual speed and Duplex.
If my Supported link mode is set low (say 10/Half for some reason) but my switch supports
1000baseT/Ful then I'l use ethtool -s ethX to change my ethernet settings to 1000baseT/Ful .
Just about anything you see from: ethtool ethX, can be changed with ethtool -S ethX. In this
case you would use the following:
ethtool -S eth0 speed 1000 duplex full autoneg on

QUESTION: 10
DTrace is being ported from Solaris to Oracle Linux. Which three statements are true for the
DTrace tool?

A. DTrace allows static and dynamic tracing of your applications and your kernel.
B. DTrace tool is used to compile debug kernel modules and device drivers
C. DTrace allows you to dynamically define probe points on the fly.
D. DTrace probes and probe points are usually defined by the user using scripts written in a
language called D.
E. DTrace tool is based on the strace Linux tool and includes both user and kernel strace
features.
Answer(s): A, C, D
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 programming.
