Which of the following are types of crosstalk? (Choose two)

Near end crosstalk (NEXT)
Far end crosstalk (FEXT)
Alien crosstalk (AXT)
DXT

Correct Answer(s)

A. Far end crosstalk (FEXT)
A. Alien crosstalk (AXT)

Explanation

Far end crosstalk (FEXT) and Alien crosstalk (AXT) are types of crosstalk. FEXT occurs when the signal from one wire interferes with the signal on an adjacent wire at the far end of the cable. AXT, on the other hand, refers to crosstalk that occurs between cables that are not part of the same transmission system. Both FEXT and AXT can degrade the quality of the transmitted signal and cause errors or loss of data.

What command must be issued to configure frame relay encapsulation, given the requirement that there are multiple vendors involved?

Answer 2
Answer 3
Answer 5

Correct Answer

A. Answer 3

Explanation

To configure frame relay encapsulation when multiple vendors are involved, the command that must be issued is "frame-relay encapsulation ietf". This command sets the encapsulation type to IETF, which is a standard encapsulation method that is compatible with multiple vendors. This ensures that the frame relay connection can be established and maintained successfully between devices from different vendors.

What protocol resolves MAC addresses to IP addresses?

DHCP
RARP
ARP
DNS

Correct Answer

A. ARP

Explanation

ARP (Address Resolution Protocol) is the correct answer. ARP is a protocol used to resolve MAC addresses to IP addresses on a local network. It allows devices to find the MAC address of another device by sending an ARP request. The device with the corresponding IP address then responds with its MAC address, allowing communication between devices at the data link layer. DHCP (Dynamic Host Configuration Protocol) is used to assign IP addresses to devices, RARP (Reverse Address Resolution Protocol) is used to resolve IP addresses to MAC addresses, and DNS (Domain Name System) is used to resolve domain names to IP addresses.

What command disables the use of Frame Relay LMI messages?

Frame-relay lmi-t392dce
Fr-atm connect dlci

Correct Answer

A. Frame-relay lmi-t392dce

Explanation

The command "frame-relay lmi-t392dce" disables the use of Frame Relay LMI messages. LMI (Local Management Interface) messages are used to exchange information between the Frame Relay switch and the connected devices. By disabling these messages, the device will not send or receive LMI messages, which can be useful in certain scenarios where LMI is not required or causes issues.

Local Area Network
Local Area Networking
Line Area Network

Correct Answer

A. Local Area Network
