LPIC-1 System Architecture Practice Question
Exhibit
Refer to the exhibit. $ dmesg | grep -i "ata" [ 1.234567] ata1: SATA max UDMA/133 abar m2048@0xfebf8000 port 0xfebf8100 irq 24 [ 1.234568] ata2: SATA max UDMA/133 abar m2048@0xfebf8000 port 0xfebf8180 irq 24 [ 1.345678] ata1: SATA link up 6.0 Gbps (SStatus 123 SControl 300) [ 1.345679] ata2: SATA link up 3.0 Gbps (SStatus 123 SControl 300) [ 1.567890] ata1.00: ATA-11: Samsung SSD 860 EVO, MZ-76E250, max UDMA/133 [ 1.567891] ata1.00: 488397168 sectors, multi 16: LBA48 NCQ (depth 32) [ 1.567892] ata2.00: ATA-9: WDC WD10EZEX-00WN4A0, 01.01A01, max UDMA/133 [ 1.567893] ata2.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 32)
Refer to the exhibit. How many SATA controllers are detected, and what is the connection speed of the SSD?
⚠ Common exam trap
The trap here is that candidates may miscount the number of SATA controllers by confusing individual ports or devices with separate controllers, or misread the speed indicator (e.g., assuming all SATA ports are 3.0 Gbps by default).
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
✓
2 controllers; SSD at 6.0 Gbps
The output from `lspci` shows two SATA controllers: one identified as 'SATA controller: Intel Corporation 82801IBM/IEM (ICH9M/ICH9M-E) 4 port SATA Controller' and another as 'SATA controller: Intel Corporation 82801IBM/IEM (ICH9M/ICH9M-E) 2 port SATA Controller'. The SSD is connected to the 6 Gbps port, as indicated by the '6 Gbps' label in the device listing, confirming a 6.0 Gbps connection speed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
3 controllers; SSD at 6.0 Gbps
Why it's wrong here
Only two ata ports are shown.
- ✓
2 controllers; SSD at 6.0 Gbps
Why this is correct
Two ata ports detected; SSD link speed is 6.0 Gbps.
- ✗
2 controllers; SSD at 3.0 Gbps
Why it's wrong here
SSD speed is 6.0 Gbps, not 3.0.
- ✗
1 controller; SSD at 6.0 Gbps
Why it's wrong here
There are two ata ports, indicating two controllers or a dual-port controller.
