200-901 Infrastructure and Automation Practice Question
Exhibit
Refer to the exhibit. R1#show run | section interface GigabitEthernet0/1 interface GigabitEthernet0/1 ip address 192.168.1.1 255.255.255.0 duplex auto speed auto ! R1#show ip interface GigabitEthernet0/1 GigabitEthernet0/1 is up, line protocol is up Internet address is 192.168.1.1/24 Broadcast address is 255.255.255.255 Address determined by non-volatile memory MTU is 1500 bytes Helper address is not set Directed broadcast forwarding is disabled Outgoing access list is not set Inbound access list is not set
Refer to the exhibit. An automation script expects the interface IP address to be configured via DHCP. Based on the output, what is the current configuration source for the IP address?
⚠ Common exam trap
Cisco often tests the distinction between 'how an IP is assigned' (DHCP vs. manual) and 'where the config is stored' (running-config vs. NVRAM), leading candidates to mistakenly think any saved config implies DHCP when it actually indicates manual configuration.
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
✓
Manual configuration (NVRAM)
The output shows 'IP address is 192.168.1.1, subnet mask is 255.255.255.0' with no DHCP or BOOTP flags, and the configuration is stored in NVRAM (startup-config). This indicates the IP was manually configured (typed by an administrator) and saved, not obtained via DHCP. Option C is correct because the source is manual configuration from NVRAM.
