CSA Server Configuration & Management 2 — Questions and Answers
Question 1: Which server role is responsible for assigning IP addresses automatically to clients on a network?
- DNS Server
- DHCP Server (Correct answer)
- Proxy Server
- File Server
Correct answer: DHCP Server
A DHCP (Dynamic Host Configuration Protocol) server automatically assigns IP addresses and other network settings to client devices.
Question 2: What is the purpose of a reverse proxy server in a web infrastructure?
- Assign IP addresses to web clients
- Forward client requests to backend servers and return responses (Correct answer)
- Store static website files for fast delivery
- Manage DNS records for domain resolution
Correct answer: Forward client requests to backend servers and return responses
A reverse proxy sits in front of backend servers, forwarding client requests to them and returning the response, providing load balancing and security.
Question 3: Which RAID level provides disk striping with parity, requiring a minimum of 3 drives?
- RAID 0
- RAID 1
- RAID 5 (Correct answer)
- RAID 10
Correct answer: RAID 5
RAID 5 uses block-level striping with distributed parity across at least 3 drives, balancing performance and fault tolerance.
Question 4: What does the acronym 'IOPS' stand for in server storage performance metrics?
- Input/Output Per Second (Correct answer)
- Internal Operations Per Session
- Indexed Output Processing Speed
- Integrated OS Performance Score
Correct answer: Input/Output Per Second
IOPS (Input/Output Operations Per Second) measures how many read/write operations a storage device can perform each second.
Question 5: Which server management protocol uses port 161 for monitoring and managing network devices?
- SSH
- SNMP (Correct answer)
- SMTP
- ICMP
Correct answer: SNMP
SNMP (Simple Network Management Protocol) uses UDP port 161 to monitor and manage network devices and servers.
Question 6: What is a 'hot spare' in the context of server storage?
- A backup power supply unit ready to take over
- A standby drive that automatically replaces a failed drive in a RAID array (Correct answer)
- An extra server kept powered on for failover
- A second network card configured for failover
Correct answer: A standby drive that automatically replaces a failed drive in a RAID array
A hot spare is an idle drive in a RAID array that automatically begins rebuilding data when an active drive fails.
Question 7: Which type of server virtualization allows multiple operating systems to run simultaneously on a single physical host?
- Clustering
- Load balancing
- Hypervisor-based virtualization (Correct answer)
- Network segmentation
Correct answer: Hypervisor-based virtualization
A hypervisor (Type 1 or Type 2) enables multiple virtual machines, each running its own OS, to share a single physical server's hardware resources.
