Question 1

While analyzing a network packet capture to diagnose a communication failure between a proprietary industrial control system and a monitoring server, an engineer notices that the data payload is encapsulated with headers corresponding to the Internet and Transport layers of the TCP/IP suite. Which specific layers of the OSI/RM (Open Systems Interconnection Reference Model) do these TCP/IP layers directly map to?

Accepted Answer

The TCP/IP Internet layer maps to OSI Layer 3 (Network), and the TCP/IP Transport layer maps to OSI Layer 4 (Transport).

Answer

The TCP/IP Internet layer maps to OSI Layer 2 (Data Link), and the TCP/IP Transport layer maps to OSI Layer 3 (Network).

Answer

The TCP/IP Internet layer maps to OSI Layer 4 (Transport), and the TCP/IP Transport layer maps to OSI Layer 5 (Session).

Answer

The TCP/IP Internet layer maps to OSI Layers 1 and 2 (Physical and Data Link), and the TCP/IP Transport layer maps to OSI Layer 3 (Network).

Question 2

A university campus is revamping its physical network architecture. The core infrastructure relies on a single high-speed fiber backbone spanning the campus. Off this backbone, individual department buildings have central switches that connect to multiple endpoint workstations in a radial pattern.

Which of the following terms best describes this specific architectural implementation?

```mermaid
graph TD
subgraph Backbone [High-Speed Fiber Backbone]
B1((Node)) --- B2((Node)) --- B3((Node))
end
subgraph DeptA [Department A]
B1 --- SW1[Switch]
SW1 --- PC1[PC]
SW1 --- PC2[PC]
SW1 --- PC3[PC]
end
subgraph DeptB [Department B]
B2 --- SW2[Switch]
SW2 --- PC4[PC]
SW2 --- PC5[PC]
end
```

Accepted Answer

A hybrid star-bus topology, combining a central linear backbone with radial departmental endpoints.

Answer

A pure mesh topology, as all endpoint workstations ultimately have a path to communicate with one another.

Answer

A pure ring topology, as the fiber backbone creates a continuous loop of data transmission.

Answer

A hybrid star-ring topology, because the switches form a star while the backbone operates via token passing.

Question 3

A data engineering team is evaluating database models for a new analytics platform. They need to process massive volumes of unstructured log data from thousands of IoT devices globally. Which TWO characteristics correctly contrast a distributed architecture like Hadoop with a traditional centralized SQL database model in this scenario? (Select TWO)

Accepted Answer

Hadoop utilizes a distributed file system to store data across multiple commodity servers, whereas a traditional SQL database typically relies on centralized storage.

Accepted Answer

Hadoop brings the processing logic directly to the nodes where the data resides, whereas traditional SQL databases usually pull data into a central processing engine.

Answer

Traditional SQL databases excel at processing unstructured data, while Hadoop requires strict, predefined schemas before data can be ingested.

Answer

Traditional SQL databases are considered decentralized architectures because they use client-server communication models.

Answer

Hadoop is primarily designed for high-speed, real-time transactional processing (OLTP), while SQL is strictly for batch processing.

Question 4

True or False: The primary distinction between a Local Area Network (LAN) and a Wide Area Network (WAN) is determined strictly by the physical length of the cables used, rather than the administrative boundaries or geographic scope of the network.

Accepted Answer

False
