Hindi ipinapakita kung alin ang tamang sagot, kaya sorpresa pa rin ang mga ito pagdating ng laro.
Tanong 1
Which industrial protocol is the vendor-neutral standard often used to read data from PLCs?
- OPC UA
- SNMP
- SMTP
- LDAP
Tanong 2
In MQTT, what does a client connect to in order to publish and subscribe?
- A topic server
- A broker
- A gateway hub
- A message queue
Tanong 3
A sensor reading must arrive exactly once, with no duplicates. Which MQTT QoS level guarantees this?
- QoS 1 with retain
- QoS 1
- QoS 2
- QoS 3
Tanong 4
How does a device usually authenticate to AWS IoT Core over MQTT?
- Username and password
- Shared API key
- IP allow-list
- X.509 client certificate
Tanong 5
Old PLCs speak Modbus only. Where is the data typically translated to MQTT?
- Inside AWS IoT Core
- On an edge gateway
- In the MQTT broker
- In the cloud database
Tanong 6
Which AWS IoT Core feature routes incoming messages to services like S3, Lambda or Kinesis?
- Rules engine
- Device shadow
- Fleet indexing
- Job service
Tanong 7
An app needs a machine's last reported state even while the machine is offline. What fits best?
- A retained topic in S3
- A Lambda cache layer
- A Device Shadow
- A Kinesis stream
Tanong 8
The factory's internet link drops for an hour. What prevents data loss at the edge?
- Higher MQTT QoS in the cloud
- A larger cloud broker
- Shorter keep-alive timers
- Store-and-forward buffering
Tanong 9
Why is a robot's emergency stop kept in the PLC rather than run from the cloud?
- Cloud bills are too high
- Latency must be deterministic
- MQTT can't carry booleans
- AWS forbids control use
Tanong 10

- Level 0
- Level 2
- Level 3
- Level 4
