Choosing between two certifications

Should you take CompTIA Network+ or CySA+?

Network+ first, and in most cases Security+ before CySA+. CySA+ is an analyst exam: it puts logs, scan results and alerts in front of you and expects you to understand the networks they come from.

Where they overlap

The shared ground

Network+ has a Network Security domain and teaches the protocols, ports and segmentation that CySA+ evidence is full of. CySA+ does not teach any of that again; it expects you to read it fluently while you work through a security problem.

  • Network+ builds, CySA+ investigatesNetwork+ (N10-009) covers networking concepts, implementation, operations, security and troubleshooting. CySA+ (CS0-004) covers security operations, vulnerability management, incident response and management, and reporting and communication.
  • CySA+ gives you more time, for harder readingCySA+ allows 165 minutes for up to 85 questions; Network+ allows 90 minutes for up to 90. The extra time is there because CySA+ questions carry evidence you have to interpret, not facts you can recall.
  • The pass marks differNetwork+ needs 720 and CySA+ needs 750, both on CompTIA’s 100–900 scale, and both exams mix multiple-choice and performance-based questions.
  • Security+ sits between themCySA+ builds on the vocabulary Security+ teaches: controls, threats, vulnerabilities and incident response. Going from Network+ straight to CySA+ means learning that vocabulary and the analyst’s job at the same time.
Which order

Taking them in sequence

The usual path is Network+, then Security+, then CySA+. If you already work in a SOC or on a security team you can move faster, but networking is the one thing CySA+ never stops assuming.

Question 1 of 3 · Network+ · Network architecture and protocols

Small packets cross a VPN, but larger packets fail. A capture shows that fragmentation is blocked, while the physical links remain healthy. Which investigation best targets the size-dependent failure?

Answer and explanation

Best answer: Path MTU and tunnel overhead

Tunnel overhead reduces available packet size. Examine the path MTU and the handling of packets that exceed it before changing unrelated services.

Why the other choices fit less well

DNS caching, application timeout, and DHCP lease duration do not explain a verified packet-size boundary across the tunnel.

Question 2 of 3 · CySA+ · Security monitoring and threat detection

A signed administrative utility runs from an unusual parent process with encoded arguments and repeated connections to a rare destination. Authorized scheduled tasks do not explain it. What should guide the next triage step?

Answer and explanation

Best answer: Correlate process ancestry, arguments, connections, and surrounding events

A legitimate signed utility can be abused. The unusual execution context and network behavior justify a focused investigation, but still need corroboration before a final conclusion.

Why the other choices fit less well

A signature alone does not prove benign use. Blocking one destination and closing the case loses scope and execution context; common tool usage does not invalidate the observed evidence.

Question 3 of 3 · Network+ · Networking concepts

Which address belongs to an RFC 1918 private IPv4 range and requires an appropriate gateway or translation arrangement to communicate with the public internet?

Answer and explanation

Best answer: 172.20.14.8

172.20.14.8 lies within 172.16.0.0/12, one of the RFC 1918 private ranges. Private addresses are not globally unique public internet addresses.

Why the other choices fit less well

172.32.14.8 is outside 172.16.0.0–172.31.255.255. 192.169.1.8 is outside 192.168.0.0/16, and 11.0.0.8 is outside 10.0.0.0/8.
