ADSL Interleave Mode :

Interleave mode is used in ADSL to improve error correction by interleaving data bits before transmission.

This process introduces additional latency (delay) but enhances stability by reducing the impact of impulse noise.

Why B?

Better stability : Interleaving spreads errors across multiple frames, making it easier to correct them.

Longer delay : The interleaving process adds latency due to the time required to reorder data bits.

Other Options :

A : Incorrect because interleave mode improves stability, not worsens it.

C : Incorrect because interleave mode increases delay, not reduces it.

D : Incorrect because interleave mode improves stability.

Thus, the correct answer is B .

VLANs (Virtual Local Area Networks) are used to logically segment a network into smaller broadcast domains. VLANs can be categorized using various methods:

Port-Based VLANs :

VLAN membership is determined by the switch port to which a device is connected.

Example: Ports 1--10 belong to VLAN 10, and ports 11--20 belong to VLAN 20.

Protocol-Based VLANs :

VLAN membership is determined by the protocol type (e.g., IPv4, IPv6, or AppleTalk) in the packet header.

MAC Address-Based VLANs :

VLAN membership is determined by the MAC address of the device.

Example: Devices with specific MAC addresses are assigned to VLAN 10.

Physical Location-Based VLANs :

VLANs are not categorized based on physical locations. While VLANs can be used to group devices in different physical locations, this is not a standard method of VLAN categorization.

Thus, the correct answer is C , as VLANs are not categorized based on physical locations.

Optical Splitter Overview :

Optical splitters are passive devices used in PON (Passive Optical Network) systems to divide the optical signal from the OLT into multiple paths for ONUs.

Standard Split Ratios :

Common split ratios include:

1:4 : Divides the signal into 4 paths.

1:8 : Divides the signal into 8 paths.

1:16 : Divides the signal into 16 paths.

1:32 : Divides the signal into 32 paths.

1:64 : Divides the signal into 64 paths.

Non-standard split ratios like 1:14 or 1:18 are not supported because they do not align with the design principles of PON systems.

Why B, C?

1:14 and 1:18 are not standard split ratios and are not used in PON systems.

Thus, the correct answers are B, C .
