Sample Question

See the Quality

Harder than the real exam, with detailed explanations

Sample — 100-140

A user reports their wired desktop cannot reach any websites, but a colleague at the next desk on the same switch works fine. The desktop shows an IP address of 169.254.12.7. What is the most likely cause?

A

The DNS server address is incorrect

B

The desktop failed to obtain an address from DHCP and self-assigned an APIPA address

C

The default gateway is misconfigured on the router

D

The website is down for the affected user only

Explanation

A 169.254.x.x address is an APIPA (Automatic Private IP Addressing) address, assigned when a client cannot reach a DHCP server. Because the colleague on the same switch works, the network path is fine — the issue is local DHCP failure (bad cable to that port, disabled NIC, or DHCP exhaustion). A DNS error would still show a valid leased IP. A gateway misconfiguration would affect everyone, not one host.

Is CCST IT Support worth it?
Yes, for anyone starting an IT support or help desk career. It is a recognized entry credential that demonstrates practical troubleshooting ability and pairs well with CompTIA A+ for a strong foundational profile.
How hard is the CCST IT Support exam?
CCST IT Support is entry-level and among the most approachable IT certifications. Most candidates pass with 3–5 weeks of study. The main challenge is applying a structured troubleshooting approach rather than memorizing facts.
Do I need experience for CCST IT Support?
No prior professional experience is required. Basic familiarity with computers, operating systems, and home networking is enough to start. The exam targets people entering the IT support field.
How many questions are on the CCST IT Support exam?
Cisco does not publish a fixed question count for CCST exams; expect roughly 35 questions in a 50-minute window. Question types include multiple-choice and interactive items.
What is the CCST IT Support passing score?
Cisco does not publish an exact cut score for CCST exams. A consistent score of around 70% or higher on quality practice tests is a reliable indicator of readiness.
How long does it take to prepare for CCST IT Support?

Both are entry-level support credentials. CompTIA A+ is broader and more widely requested by employers, while CCST IT Support is shorter, cheaper, and a fast way to prove core support skills. Many candidates earn both.
