Computer Networks Questions
-
42G
-
504
-
68G
-
None of the above
C
Correct answer
Explanation
The model designation for the 8-port embedded Multimedia Terminal Adapter (eMTA) used in these installations is the 68G (often referring to the Arris TM608G). The other options, such as 42G or 504, refer to different hardware models or configurations that do not feature the 8-port capacity required for these setups.
-
42G
-
504
-
68G
-
None of the above
A
Correct answer
Explanation
The Arris 42G model is the 2-port eMTA device. This is distinct from the 504 model which is a 4-port variant, and the 68G which represents a different configuration or generation.
-
Native
-
Port-In
-
All the Above
-
None of the Above
C
Correct answer
Explanation
IBLc supports two types of line provisioning: Native (new number assignment from the carrier) and Port-In (transferring an existing number from another provider). These are the two methods for establishing phone service on the IBLc platform.
-
Call display & Call Waiting
-
Call display & Call Forward
-
Virtual Lines & MLH
-
None of the Above
C
Correct answer
Explanation
Virtual Lines and MLH (Multi-Line Hunt) are incompatible features in telecom systems because MLH requires physical line assignments while Virtual Lines abstract this concept - they cannot work together on the same service. Call Display works with both Call Waiting and Call Forward, making options A and B incorrect.
-
Local Queue
-
Initiation Queue
-
Transmission Queue
-
Channel Queue
D
Correct answer
Explanation
"Channel Queue" is not a standard queue classification in messaging systems, whereas Local, Initiation, and Transmission queues are recognized types. Hence the answer marked as correct aligns with the factual distinction, making the stored answer valid.
-
Cable in home & active
-
Cable not wired in home
-
Cable in home disconnected
-
No subscriber previously in home
A
Correct answer
Explanation
A “Hot address” indicates a cable line that is installed in the home and actively providing service, which is the correct description among the choices.
-
Cable in home & active
-
Cable not wired in home
-
Cable in home disconnected
-
No subscriber previously in home
B
Correct answer
Explanation
An “Unwired address” refers to a cable line that is present at the home but not yet connected (wired) to the service, matching the selected option.
-
Cable in home & active
-
Cable not wired in home
-
Cable in home disconnected
-
No subscriber previously in home
D
Correct answer
Explanation
The definition of a Virgin address is identical to the earlier question: an address with no prior subscriber, confirming the stored answer is correct.
-
Cable in home & active
-
Cable not wired in home
-
Cable in home disconnected
-
No subscriber previously in home
C
Correct answer
Explanation
A 'Cold address' in cable terminology means cable infrastructure is physically present in the home but the service is disconnected - the customer is not currently active. This differs from a 'hot' address (active service) or a location where cable was never installed.
-
RHPc
-
RHPs
-
All above
-
None of the above
B
Correct answer
Explanation
RHPs (Residential Home Phone Standard) is the home service required for ADSL connections. This is a telecom-specific service configuration where RHPs serves as the required home service component for ADSL internet connectivity. RHPc appears to be a different service tier (possibly Commercial) and is not the correct answer for ADSL requirements.
-
Cable in home & active
-
Cable not wired in home
-
Cable in home disconnected
-
No subscriber previously in home
A
Correct answer
Explanation
A 'Hot address' in cable terminology refers to a location where cable infrastructure is already installed in the home and the service is actively connected. This represents the ideal scenario for service deployment - no physical installation needed, just service activation.
-
Cable in home & active
-
Cable not wired in home
-
Cable in home disconnected
-
No subscriber previously in home
B
Correct answer
Explanation
An 'Unwired address' indicates that cable infrastructure has not been physically installed at that location. This is distinct from 'Cold' (disconnected) and means the premises requires physical cable installation before service can be activated.
-
Cable in home & active
-
Cable not wired in home
-
Cable in home disconnected
-
No subscriber previously in home
D
Correct answer
Explanation
A “Virgin address” in cable terminology indicates an address that has never had a subscriber; the line is unused and no previous service exists there, matching the correct option.
-
Cable in home & active
-
Cable not wired in home
-
Cable in home disconnected
-
No subscriber previously in home
C
Correct answer
Explanation
A 'Cold address' in cable terminology means cable infrastructure exists in the home but the service is currently disconnected. The physical wiring is present (unlike Unwired), but the service is inactive (unlike Hot). This typically requires reactivation rather than full installation.

Symbol
-
Pinging
-
stcock management
-
cradel manager
D
Correct answer
Explanation
Cradle Manager is the application used to check network connectivity for handheld stock controllers. It monitors the connection between the handheld device and its cradle. 'Symbol' is a device manufacturer, 'Pinging' is a network utility, and 'stcock management' appears to be a typo for 'stock management' which is not the connectivity tool.
