A network technician is deployed to a branch office to resolve two network issues reported after a recent reconfiguration:
1. Laptops connected to a 2.4 GHz wireless access point (AP) experience high packet loss and poor throughput when operating near an AP configured on channel 3.
2. A newly deployed wired workstation displays an IP address of and cannot communicate with any internal network servers.
Which of the following actions should the technician take to resolve these issues? (Select TWO.)
- Reconfigure the access point operating on channel 3 to use a non-overlapping channel such as 1, 6, or 11.Cevap
- Verify the physical cable connection and check the DHCP server status for the wired workstation's subnet.Cevap
- CUpdate the local DNS server records to assign a valid dynamic IP address lease to the wired workstation.
- DIncrease the wireless channel bandwidth on the 2.4 GHz access point from 20 MHz to 40 MHz.
Cevap
The technician should reconfigure the wireless access point operating on channel 3 to use a non-overlapping channel (1, 6, or 11) and verify physical cabling/DHCP server reachability for the wired workstation.
Reconfiguring the access point from channel 3 to channel 1, 6, or 11 eliminates adjacent channel overlap in 2.4 GHz wireless networks. Additionally, inspecting physical cabling and DHCP server functionality addresses the root cause of an APIPA self-assignment () on the wired workstation.
