Understanding ARP Entries:

Each ARP entry associates a MAC address with an IP address dynamically or statically.

In the table, the MAC address 00e0-fc99-9999 is linked to multiple IP addresses across different interfaces.

Dynamic MAC Address Assignment:

As the host changes its IP address, the MAC address remains consistent.

Conclusion:

The statement is TRUE because the MAC address 00e0-fc99-9999 appears with three different IP addresses dynamically.

OSPF does not use TCP or UDP because it has its own reliable transmission mechanisms.

OSPF packets are encapsulated directly in IP packets using protocol number 89.

TCP (A) is used for connection-oriented communication, but OSPF does not rely on it.

UDP (C) is used for connectionless communication, but OSPF does not use it.

HTTP (B) is an application-layer protocol and irrelevant here.

Thus, the correct answer is D (IP).

The Forward Delay timer in STP helps prevent temporary loops by setting a delay for ports transitioning through Listening and Learning states before reaching the Forwarding state. This wait period ensures that all switches have updated topology information, reducing the risk of broadcast storms or loops​.

Comprehensive Explanation: The command dot1q termination vid 100 in the configuration specifies that the sub-interface is configured to receive tagged data frames for VLAN 100. VLAN tagging ensures that frames are properly identified and routed through the correct VLAN, and the sub-interface is associated with a specific VLAN ID to handle the tagged traffic.

Detailed Explanation:Access Control Lists (ACLs) are processed in sequential order, meaning that once a packet matches a rule, subsequent rules are ignored. To ensure that more specific (strict) conditions are applied, strict rules should be listed first, followed by loose rules. (Reference: HCIA-Datacom Training Material, ACL Configuration and Rule Order)

Detailed Explanation:If the username does not contain the delimiter "@" followed by a domain name, the user is automatically assigned to the default domain. In this case, since the username "huawei" does not specify a domain, the user belongs to the default domain​​.

Detailed Explanation:In RSTP, there are three port states: Discarding, Learning, and Forwarding. These states replace the five traditional STP states by combining them to optimize network convergence​​.

Network Communication Types:

A: Downloading emails is an example of client-server communication.

B: Accessing a website involves HTTP/HTTPS communication.

C: Chatting via instant messaging involves real-time data exchange using protocols like XMPP or WebSockets.

D: Watching online videos involves streaming protocols like HTTP Live Streaming (HLS).

Conclusion:

All options represent common types of network communication between devices.
