A valid IPv6 address is represented as a set of 16-bit hexadecimals separated by colons. The address is divided into eight groups, and each 16-bit group is represented by four hexadecimal numbers. A valid IPv6 address is in the form “x1:x2:x3:x4:x5:x6:x7:x8” where each xi is a hexadecimal string which may contain digits, lower-case English letter (‘a’ to ‘f’) and upper-case English letters (‘A’ to ‘F’). Leading zeros are allowed in xi. The longest sequence of consecutive all-zero fields is replaced with two colons (::).1

Option A is the only one that follows these rules. Option B has two consecutive colons twice, which is not allowed. Option C has an invalid hexadecimal character ‘g’. Option D uses percentage signs instead of colons, which is not a valid separator. Option E uses dots instead of colons, and has two consecutive dots, which are both invalid.

Broadcast addresses are used to send a message to all devices on a network segment. IPv4 supports broadcast addresses, but IPv6 does not. Instead, IPv6 uses multicast addresses, which are used to send a message to a group of devices that have joined a multicast group. Multicast addresses are more efficient and flexible than broadcast addresses, as they allow the sender to specify the recipients more precisely and avoid unnecessary network traffic. IPv6 also supports anycast addresses, which are used to send a message to the nearest device that provides a specific service. Anycast addresses are useful for load balancing and redundancy. References:

The parameter that must be passed to ifconfig to activate a previously inactive network interface is up. The up parameter tells the kernel to activate the network interface and allow it to send and receive packets. The opposite of up is down, which deactivates the network interface. The up parameter is part of the topic 109.2: Basic network configuration, which is one of the objectives of the LPI Linux Administrator - 102 exam12. References: 1: https://learning.lpi.org/en/learning-materials/102-500/  2: https://www.lpi.org/our-certifications/exam-102-objectives/
