AT&T TKT II Practice Tests [2024]

What Is the AT&T TKT II?

The Technical Knowledge Test II is a knowledge-based test that is part of the hiring process for technical jobs at AT&T. The test is designed to assess your knowledge of technical concepts required to perform certain technical positions in the company.

The test consists of 100 multiple-choice questions to answer in 1 hour and 40 minutes.

It covers five categories –

• Basic Electricity
• Basic computer knowledge
• Digital communication and transmission
• Read and interpret technical information
• Basic math

AT&T TKT II Test Section #1 – Basic Electricity

The Basic Electricity category of the Technical Knowledge Test includes more than 20 topics, including Alternative current (AC) and direct current (DC), Electrical transmission and waveforms, Electrostatic discharge, and identifying and using various electrical units, such as Voltage, Current, Resistance, and Power.

Sample Question

Identify the relay type shown below:

A. SPST

B. SPDT

C. DPDT

D. None of the Above 

Correct Answer

Incorrect Answer

The correct answer is B.

SPDT is a single pole double throw relay. The schematic diagram of an SPDT is shown below.

There are three terminals:

• COM (common)
• NO (normally open)
• NC (normally closed).

When the relay is OFF, the COM terminal is connected with the NC terminal and when the relay is ON, the COM terminal is connected with the NO terminal. The schematic diagram of SPST (single pole single throw) and DPDT (double pole double throw) are also shown below.

AT&T TKT II Test Section #2 – Basic Computer Knowledge

The Basic computer knowledge category of the Technical Knowledge Test includes more than 10 topics, including Accessories/ System Tools, Control Panels, and Network Neighborhood/My Network Places.

Sample Question

Which one of the following is True for a buffer IC?

AT&T TKT II Test Section #3 – Digital Communication and Transmission

The Digital communication and transmission category of the Technical Knowledge Test includes the topics of advantages and disadvantages, Digital/Analog Conversion, Bit Frame, Bit Stream, T-carriers-hierarchy, overhead, framing, and data rates, and Units of measurement, including Binary Systems.

Sample Question

What is the binary value of the octal number 258?

011001b

010101b

25

101010b

Correct Answer

Incorrect Answer

Octal numbers have a base of eight numbers starting from 0 to 7. These numbers are represented with a subscript “8” after the number. Each hexadecimal number is represented by four binary bits. Since there are 2 octal numbers, the resultant binary of the given number will be 6 binary bits. Follow the figure provided below:

 

AT&T TKT II Test Section #4 – Read and Interpret Technical Information

The Read and Interpret Technical Information category of the Technical Knowledge Test includes the topics of technical instructions, schematic diagrams, flowcharts, etc.

This is one of the most important test topics since this knowledge appears not only in this test section but also in nearly each and every OTHER section.

Although questions on the TKT-II test are multiple-choice, they will often combine knowledge of multiple domains, so memorization of separate data pieces is usually not a good strategy.

Instead, your preparation for the AT&T TKT-II test should aim to have a broad view of the topics and your test and be able to connect and integrate them.

Sample Question

What will happen if the forward button is pressed and released after a while

This question combines knowledge of print reading with troubleshooting and testing procedures. As a technical employee, you will need to use your knowledge to solve daily problems hands-on - so, such questions are going to be very common in the TKT-II test.

AT&T TKT II Test Section #5 – Basic Math

The Basic Math category of the Technical Knowledge Test includes the topics of addition, subtraction, multiplication, and division of positive and negative numbers.

While often overlooked by test-takers, this topic can be a major hurdle for those who have not touched the topic in a while and gets more candidates to fail than you may believe.

AT&T TKT II Sample Question – Basic Math

What is the value of X?

(15x)/9 = 2x + 4

What Is the Difference Between TKT and TKT II?

TKT and TKT II are both technical knowledge tests administered by AT&T as pre-employment assessment tools, and both require specific knowledge relevant to technical jobs, but they differ in their lengths and structure.

• TKT – The TKT consists of two modules –General Knowledge, with 45 questions to answer in 50 minutes, and Applied Knowledge, with 55 questions to answer in 2 hours.
• TKT II –The TKT II consists of five categories – Basic electricity, Basic computer knowledge, Digital communication and transmission, Read and interpreting technical information, and Basic math, with an overall of 100 questions to answer in 1 hour and 40 minutes.

Tips to Ace the TKT II

• Know the theory AND the practice – The TKT II assesses your applied knowledge of mechanical subjects to evaluate your practical capabilities on the job, but it also measures your understanding of the theories behind it. You should master both the theoretical aspects of each topic as well as how to use it in real life.
• If you don’t know the answer, guess! –The TKT II score is based on the number of correct answers, so if you can’t figure it out, you should guess and move on. You can always go back and correct your answer if you have enough time.
• Learn the schematics – Make sure you know to read and interpret schematics of all the TKT II’s topics. It is a crucial factor of understanding the questions and solving them.
