Question 1

The Transport layer segments data into smaller chunks, the size of which is determined by which of the following?
A) MTU
B) LLC
C) PDU
D) TCP

Accepted Answer

The Maximum Transmission Unit (MTU) determines the maximum size of data that can be transmitted over a particular network. The Transport layer segments data into smaller chunks based on the MTU of the network.

Question 7

At which layer would you find errors that were caused by EMI?
A) Data Link
B) Transport
C) Physical
D) Network

Accepted Answer

EMI (Electromagnetic Interference) refers to disturbance caused by electromagnetic radiation. This can cause errors in the physical layer of the OSI model, which deals with the electrical and physical characteristics of the transmission medium, such as cables or airwaves.

Question 13

How can you find out what your MAC address is? (Choose all that apply.)
A) Right-click on the Local Area Connection and choose status.
B) Open a command prompt and type the command arp -d.
C) Open a command prompt and type the command getmac.
D) Open a command prompt and type the command ipconfig /all.

Accepted Answer

A) Right-clicking on the Local Area Connection and choosing status will show you the MAC address among other details of the connection. C) Typing the command getmac in a command prompt will display all MAC addresses for the computer. D) Typing ipconfig /all in a command prompt will list all the TCP/IP information for each adapter, including the MAC address (listed as "Physical Address"). B) is incorrect because the arp -d command is used to delete entries from the ARP table, not to display MAC addresses.
