Q54
With consideration to half-duplex and full-duplex Ethernet, what are unique for half-duplex Ethernet?
(Select two options.)A. Half-duplex Ethernet operates in a shared collision domain.B. Half-duplex Ethernet operates in an exclusive broadcast domain.C. Half-duplex Ethernet has efficient throughput.D. Half-duplex Ethernet has lower effective throughput.E. Half-duplex Ethernet operates in an exclusive collision domain.Ans: A D

Explanation:
A single device could not be sending a frame and receiving a frame at the same time because it would mean that
a collision was occurring. So, devices simply chose not to send a frame while receiving a frame. That logic is
called half-duplex logic.
Ethernet switches allow multiple frames to be sent over different ports at the same time. Additionally, if only
one device is connected to a switch port, there is never a possibility that a collision could occur. So, LAN
switches with only one device cabled to each port of the switch allow the use of full-duplex operation. Full
duplex means that an Ethernet card can send and receive concurrently.

Q55
You are a network technician at CertKing . You have subnetted the 209.126.24.0 network with a /24 mask.
Your supervisor asks you how many usable subnetworks and usable host addresses per subnet this would
make provision for.
What would your response be?A. 1 network with 254 hostsB. 4 networks with 128 hostsC. 2 networks with 24 hostsD. 6 networks with 64 hostsE. 8 networks with 36 hostsAns: A

Explanation:
A subnet with 24 bits on would be 255.255.255.0. This subnet has only 1 network and 254 hosts.

Q45
You are a network engineer at CertKing . The company suffers a power outage. You
want to provide emergency contact service until the power is returned.
What is a standard method of providing emergency contact service during power
outages?A. Power provisioned from an alternate grid.B. Cellular phones available in emergency closets.C. Power provisioned from a backup power generator.D. A general alarm bell connected directly to emergency service provides.E. Standard handsets on LEC loop-start lines scattered throughout the facility.Ans: E


Q46
You are a network engineer at CertKing . You are installing an SPE card installed in a
Cisco ISC 7750. Your newly appointed CertKing trainee wants to know which of the
following host names he can use on the SPE card. What will your reply be? (Choose all
that apply.)A. CertK 01B. CertK :01C. CertK -01D. CertK 01E. CertK (01)Ans: A, C
Explanation: Host names should be no more than 15 characters long.
Host names should contain only the numbers 0 through 9, the letters A through Z, the letters a
through z, and hyphens (-). Using other characters might prevent other users from finding
