200-901 Question 192
Select 2A network administrator is troubleshooting connectivity issues on a network. They observe that devices are not receiving IP addresses dynamically, and hostname resolution is failing. Which combination of IP services should the administrator investigate to resolve these issues?
- A
DHCP
- B
DNS
- C
NAT
- D
SNMP
- E
NTP
Show answer and explanation
Correct answers: A, B
Explanation
To resolve issues with devices not receiving IP addresses dynamically and hostname resolution failing, the administrator should investigate DHCP and DNS services. DHCP ensures devices get IP addresses, while DNS ensures hostname-to-IP resolution works as intended. NAT, SNMP, and NTP do not directly influence these specific functionalities.
- A. Correct.
DHCP (Dynamic Host Configuration Protocol) is responsible for dynamically assigning IP addresses to devices on the network. If DHCP is not functioning, devices may not receive IP addresses, leading to connectivity issues.
- B. Correct.
DNS (Domain Name System) translates domain names to IP addresses. If DNS is not functioning, hostname resolution will fail, causing difficulty in accessing resources by name.
- C. Incorrect.
NAT (Network Address Translation) translates private IP addresses to public IP addresses for internet access. While important, NAT is not directly related to issues with IP address assignment or hostname resolution.
- D. Incorrect.
SNMP (Simple Network Management Protocol) is used for network management and monitoring. It does not play a role in IP address assignment or hostname resolution.
- E. Incorrect.
NTP (Network Time Protocol) synchronizes clocks on network devices. It is unrelated to IP address assignment or hostname resolution.
