H12-811_V1.0 Exam Dumps - HCIA-Datacom V1.0 Exam

Detailed Explanation:The Priority Code Point (PCP) field in an 802.1Q VLAN tag is 3 bits long, which gives it a value range of 0 to 7. This field is used to indicate the priority of the frame, with higher values indicating higher priority​​.

To form an EUI-64 address, the MAC address is split and FFFE is inserted in the middle, making the EUI-64 format 00E0-FCEF-FFFE-0FEC. Additionally, the 7th bit of the first byte is flipped to form the Modified EUI-64 address used in IPv6 for Stateless Address Autoconfiguration (SLAAC)​.

The wildcard mask 0.0.254.255 means:

The first and third octets are checked exactly.

The second and fourth octets can vary.

This results in a match for IPs in the range 10.0.2.0 - 10.0.2.255.

Only option D (10.0.2.1) falls within this range.

Thus, the correct answer is D (10.0.2.1).

Comprehensive Explanation: Router Advertisement (RA) packets in IPv6 are part of the Neighbor Discovery Protocol, which uses ICMPv6 (Internet Control Message Protocol for IPv6). RA messages are sent by routers to inform hosts about the presence of routers on the network and provide them with information needed for stateless address auto-configuration, such as the network prefix and default gateway.

SNMP (Simple Network Management Protocol) supports the use of traps, which are unsolicited messages sent to the SNMP manager when specific events occur. Traps enable devices to report faults or important events as they happen, facilitating proactive fault management and quicker response times by network administrators​.

DHCP (Dynamic Host Configuration Protocol) can allocate various network parameters, including:

IP address: Assigns a unique IP to each client.

Gateway address: Provides the default gateway for routing traffic.

DNS server address: Allows domain name resolution. The DHCP server does not assign an operating system, as this is outside its scope​.
