MTA certification addresses a wide spectrum of fundamental technical concepts, assesses and validates your core technical knowledge, and enhances your technical credibility. Note MTA exams do not qualify for MCP certification, nor are they a prerequisite for MCSA or MCSD certification.
The bottom number is the more important of the two. The bottom number of your BP (104) is a bit high. That's the pressure in your blood vessels after your heart has contracted and is now at momentary rest. Average is about 80. Your upper number (128) corresponds to the pressure in your vessels when your heart contracts.
Medicines will likely be started if your BP readings remain at or above these levels: 1  Top number (systolic pressure) of 140 or more in people younger than 60 years. 2  Top number of 150 or more in people 60 years and older.  Bottom number (diastolic pressure) of 90 or more.
