Your client has a 10Base2 Ehternet network which is using 160m of RG-58A/U cable and two 50 ohm terminators that are both grounded.What is wrong with his network?

  1. The terminators should be 93 ohms

  2. He should be using RG-59/U cable

  3. Only one terminator should be grounded

  4. Impedence mismatch


Correct Option: C

AI Explanation

To answer this question, we need to understand the basics of 10Base2 Ethernet networks and the requirements for proper network setup.

A 10Base2 Ethernet network, also known as Thinnet, uses RG-58A/U coaxial cable with a characteristic impedance of 50 ohms. The cable is terminated at both ends with a 50 ohm terminator. The terminators are used to absorb and dissipate any signal reflections that occur at the ends of the cable, ensuring proper signal transmission.

In the given scenario, the client's network is using 160m of RG-58A/U cable and two 50 ohm terminators that are both grounded.

Option A) The terminators should be 93 ohms - This option is incorrect. The terminators used in a 10Base2 network should be 50 ohms, not 93 ohms.

Option B) He should be using RG-59/U cable - This option is incorrect. RG-58A/U cable is the correct cable type for a 10Base2 network, not RG-59/U cable.

Option C) Only one terminator should be grounded - This option is correct. In a 10Base2 network, only one terminator should be grounded. Grounding both terminators can cause signal reflections and disrupt network communication.

Option D) Impedance mismatch - This option is incorrect. The impedance of the cable and the terminators should match. In this case, the impedance is correctly set to 50 ohms.

Therefore, the correct answer is C) Only one terminator should be grounded. This option is correct because grounding both terminators can cause signal reflections and disrupt network communication.

Of the following the one that is NOT an alogorithm that determines the shortest path for routers?

  1. SAP

  2. RIP

  3. OSPF

  4. EIGRP


Correct Option: A

The most common topology in use today among corporate users?

  1. Bus

  2. Ring

  3. Star-bus

  4. Mesh


Correct Option: C

___ uses a 93 ohm resistor?

  1. RG62

  2. RG58

  3. RG59

  4. RJ45


Correct Option: A

Device drivers can be disabled in Win 2000 Prof in Device Manager or by using the ___?

  1. ERD

  2. Recovery Console

  3. RDISK

  4. Disk Management Console


Correct Option: B

AI Explanation

To answer this question, you need to understand how to disable device drivers in Windows 2000 Professional.

Option A) ERD - This option is incorrect because the Emergency Repair Disk (ERD) is used to repair a Windows 2000 installation, not to disable device drivers.

Option B) Recovery Console - This option is correct because the Recovery Console in Windows 2000 Professional allows you to disable device drivers. The Recovery Console is a command-line tool that provides access to the system files and allows you to perform various system recovery tasks.

Option C) RDISK - This option is incorrect because RDISK is used to create a backup of the Windows 2000 system registry, not to disable device drivers.

Option D) Disk Management Console - This option is incorrect because the Disk Management Console is used to manage disk partitions and volumes, not to disable device drivers.

The correct answer is B) Recovery Console. This option is correct because the Recovery Console in Windows 2000 Professional allows you to disable device drivers.
