300-410 Practice Question: Which IP SLA operation type is used to monitor…
Which IP SLA operation type is used to monitor the availability of a TCP-based service by attempting a three-way handshake?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
TCP Connect
The TCP Connect operation (type 5) attempts to establish a TCP connection to a specified port. Success indicates the service is reachable; failure indicates a problem.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
UDP Jitter
Why it's wrong here
UDP Jitter measures packet delay variation and loss for real-time traffic such as VoIP, not service availability. It cannot perform a TCP three-way handshake, so it never confirms that a TCP port is listening. It would be the right choice when assessing jitter and latency budgets for voice or video flows.
- ✓
TCP Connect
Why this is correct
TCP Connect performs a full three-way handshake (SYN, SYN-ACK, ACK) to the target port, confirming the TCP service is genuinely listening and accepting connections. This distinguishes it from operations that only measure round-trip latency without verifying service availability.
- ✗
ICMP Echo
Why it's wrong here
ICMP Echo only tests whether the host replies to ping; it never opens a TCP session, so a listening SSH or web service on a filtered host goes undetected. It suits basic reachability and round-trip latency checks where no TCP port state needs confirming.
- ✗
HTTP
Why it's wrong here
HTTP probes retrieve a URL and validate response codes, so they only work against HTTP or HTTPS endpoints and cannot test arbitrary TCP ports such as 22 or 3306. HTTP would be correct when monitoring a web application's availability and response content.
