NEW QUESTION # 158
The tree topology is a hierarchical star topology, facilitating network expansion. A consequence of this topology is that faults on a node at a higher layer are more severe.
- A. FALSE
- B. TRUE
Answer: B
Explanation:
Detailed Explanation:In a tree topology, nodes are arranged hierarchically with root nodes at the top and leaf nodes at the base. This structure is often used in larger networks because it supports scalability and easy addition of nodes. However, if a higher-level node (e.g., root or intermediate node) fails, all dependent nodes in its subtree lose connectivity. Therefore, faults at higher layers have a more significant impact than faults at the leaves. (Reference: HCIA-Datacom Training Material, Network Topology Types)
NEW QUESTION # 159

NEW QUESTION # 163
Which is a valid EUI-64 address?
- A. 00E0-FCEF-FFFE-0FEC
- B. 00E0-FCFF-FEEF-0FEC
- C. 02E0-FCEF-FFFE-0FEC
- D. 02E0-FCFF-FEEF-0FEC
Answer: C
Explanation:
Detailed Explanation:The EUI-64 format splits a MAC address into two parts and inserts "FFFE" in the middle. The Universal/Local (U/L) bit is flipped, so a valid EUI-64 address would be 02E0-FCEF-FFFE-
0FEC.
