CTP Network & Infrastructure Management 1 — Questions and Answers
Question 1: Which network topology provides the highest fault tolerance by connecting every node to every other node?
- Star topology
- Bus topology
- Mesh topology (Correct answer)
- Ring topology
Correct answer: Mesh topology
A full mesh topology connects every node directly to every other node, ensuring no single point of failure can isolate any device.
Question 2: What is the primary purpose of a demilitarized zone (DMZ) in network architecture?
- To isolate internal servers from each other
- To host public-facing services while protecting the internal network (Correct answer)
- To increase bandwidth for external connections
- To encrypt all traffic between network segments
Correct answer: To host public-facing services while protecting the internal network
A DMZ hosts services accessible to external users (e.g., web servers) while preventing direct access to the internal corporate network.
Question 3: Which protocol is used to dynamically assign IP addresses to network devices?
- DNS
- SNMP
- DHCP (Correct answer)
- FTP
Correct answer: DHCP
Dynamic Host Configuration Protocol (DHCP) automatically assigns IP addresses, subnet masks, gateways, and other network configuration to devices.
Question 4: What does VLAN segmentation primarily achieve in an enterprise network?
- Increases physical cable length limits
- Logically separates network traffic without requiring physical separation (Correct answer)
- Automatically assigns IP addresses across subnets
- Provides end-to-end encryption for all traffic
Correct answer: Logically separates network traffic without requiring physical separation
VLANs create logical network segments on shared physical infrastructure, reducing broadcast domains and improving security and manageability.
Question 5: In a three-tier network architecture, which tier handles routing between different network segments?
- Access layer
- Core layer
- Distribution layer (Correct answer)
- Presentation layer
Correct answer: Distribution layer
The distribution layer aggregates access layer connections and handles inter-VLAN routing, policy enforcement, and traffic filtering between tiers.
Question 6: Which infrastructure redundancy technique uses two network paths where only one is active at a time?
- Active-active failover
- Active-passive failover (Correct answer)
- Load balancing
- Link aggregation
Correct answer: Active-passive failover
Active-passive failover keeps one path on standby, switching traffic to it only when the primary path fails.
Question 7: What is the function of SNMP in network infrastructure management?
- Encrypts data in transit across the network
- Monitors and manages network devices by collecting performance data (Correct answer)
- Assigns hostnames to IP addresses
- Establishes secure tunnels between remote sites
Correct answer: Monitors and manages network devices by collecting performance data
Simple Network Management Protocol (SNMP) allows administrators to monitor device health, collect metrics, and configure managed network equipment.
