A help desk technician has been tasked with installing an IP phone in a small office with an unmanaged switch. When connected to an RJ45 receptacle, the phone does not boot. Which of the following is the QUICKEST way to resolve this issue?
A help desk technician has been tasked with installing an IP phone in a small office with an unmanaged switch. When connected to an RJ45 receptacle, the phone does not boot. Which of the following is the QUICKEST way to resolve this issue?
An IP phone typically requires Power over Ethernet (PoE) to function. In a small office setup with an unmanaged switch that may not provide PoE, the quickest way to resolve the issue is to install a PoE injector. This injector will provide the necessary power to the phone through the Ethernet cable, allowing it to boot. Other options such as upgrading the Ethernet cable, replacing the phone, or changing ports on the switch are less likely to address the root cause of the issue, which is the lack of power.
C is the correct answer.
Agreed- An unmanaged switch doesn't provide Power over Ethernet (PoE), which is required for the IP phone to have power.
That is not entirely correct. There are such things as unmanaged switches that provide PoE
remember that it asked for the quickest way
A,B,C all require sourcing new parts/devices. Changing ports is the quickest
However, it doesn't power on, so changing the switch port wouldn't do anything. C is the only correct answer, as that would provide the power the phone needs to boot.
I say, C because IP phone requires POE and switching ports is very unlikely to fix the issue as they are all likely to be in the same state and we were not told that the Switch had POE capability which an IP phone requires.
Quickest way to resolve this issue** Taking the cable out and putting it into a new port to may be get the phone to boot sounds like a waste of time. Also we know the phone needs *PoE*.. So if we look at the possible answers, only ONE is a guarantee to work immediately and that would be C. (We don't even know if the Unmanaged switch has PoE capabilities)
Assuming that the phone requires power, POE injector answers this. Changing ports allows for another port that is set up for PoE, maybe a different VLAN, I dunno. I have to think that you would hope that the switch and power supply have anough juice to power the phone, sometimes too many phones for the switch to power, so the PoE injector would be the answer, but then again Im drunk so.....
The question asks for the QUICKEST way to RESOLVE this issue. It is a unmanaged switch in a SOHO and IP phones need POE to boot. We do not know if the switch has other ports capable of POE, but due to the environment it is in and type of switch, it very well may not. Disregarding that fact, the only answer out of the given choices, that guarantees the QUICKIEST and RESOLUTION (resolves), is a POE injector. Changing ports does not guarantee it will actually RESOLVE the issue, but it does fulfill the QUICKIEST, but thats not what the question asks.
Don't overthink, device doesn't boot, logical cause is it doesn't get power, logical answer it needs power. D needs too many other variables to know if it works, so C is the answer.
But actually, considering how CompTIA wants you to think, it probably is D. If they're using VoIP, they probably have switches with PoE capabilities. Lots of assumptions, but eh.
Unmanaged switch’s has POE
Both C and D are good answers however, the question asks what the quickest action is. Therefore the answer is D.
There are unmanaged switches with both normal ports and PoE ports. Switching ports is the quickest way to resolve the issue.
Unmanaged Power over Ethernet (PoE) switches are basic plug-and-play devices with no remote configuration, management, or monitoring options. Antaira offers a full line of industrial unmanaged PoE switches that boast a variety of port-count, speed (including 10Gigabit), mounting, and fiber.
YES the right answer is D.
The question asks for the QUICKEST solution. Yes C might be the best quick solution but all A,B,C answers require sourcing parts whereas D is literally moving one wire on a switch. If that doesn't work you can escalate it to get parts. Therefore D is the QUICKEST option there
An IT department most likely would have the required parts and would be just as fast. If D doesn't work, you still will have to do C, making D not quicker than C. With C you're guaranteed the solution works.
Hey, but if D works, you wouldn't have to deal with C and therefore the quickest will be D.
It needs to be powered
C is correct
Based on what everyone else has already said, C makes the most sense as the phone requires PoE.
The answer is C IP phones typically require Power of Ethernet to function and an unmanaged switch may not support PoE
C is the correct answer
