CTP Network & Infrastructure Management 2 — Questions and Answers
Question 1: Which metric best represents the maximum data transfer capacity of a network link?
- Latency
- Jitter
- Bandwidth (Correct answer)
- Packet loss rate
Correct answer: Bandwidth
Bandwidth defines the maximum theoretical throughput of a network link, typically measured in Mbps or Gbps.
Question 2: What is the primary advantage of using software-defined networking (SDN)?
- Eliminates the need for physical network hardware
- Separates the control plane from the data plane for centralized management (Correct answer)
- Automatically encrypts all network traffic
- Increases hardware processing speed on switches
Correct answer: Separates the control plane from the data plane for centralized management
SDN decouples the control plane (routing decisions) from the data plane (packet forwarding), enabling centralized, programmable network management.
Question 3: Which load balancing algorithm routes each new request to the server with the fewest active connections?
- Round robin
- Least connections (Correct answer)
- IP hash
- Weighted round robin
Correct answer: Least connections
The least connections algorithm directs traffic to the server currently handling the fewest active sessions, distributing load based on real-time utilization.
Question 4: What does a network baseline measurement provide in infrastructure management?
- A security audit of all connected devices
- Normal performance metrics used as a reference for detecting anomalies (Correct answer)
- Configuration backup for all network equipment
- A list of all authorized IP addresses on the network
Correct answer: Normal performance metrics used as a reference for detecting anomalies
A baseline documents normal network behavior (traffic volume, latency, utilization) so deviations can be quickly identified as potential issues or anomalies.
Question 5: Which storage network protocol transmits SCSI commands over TCP/IP networks?
- NFS
- SMB
- iSCSI (Correct answer)
- FCoE
Correct answer: iSCSI
iSCSI (Internet Small Computer Systems Interface) encapsulates SCSI commands within TCP/IP packets, enabling block-level storage access over standard IP networks.
Question 6: In network infrastructure, what is the purpose of a proxy server?
- To assign dynamic IP addresses to clients
- To act as an intermediary between clients and external servers for caching and filtering (Correct answer)
- To route packets between different network subnets
- To monitor and log all authentication attempts
Correct answer: To act as an intermediary between clients and external servers for caching and filtering
A proxy server intercepts client requests to external resources, enabling caching, content filtering, access control, and anonymization.
Question 7: What is the purpose of Quality of Service (QoS) in network management?
- To encrypt sensitive network traffic
- To prioritize specific types of traffic to ensure performance for critical applications (Correct answer)
- To detect and block unauthorized network access
- To automatically balance traffic across multiple ISP links
Correct answer: To prioritize specific types of traffic to ensure performance for critical applications
QoS policies assign priority to traffic types (e.g., VoIP, video conferencing) ensuring latency-sensitive applications receive preferential bandwidth and low-delay treatment.
