Here you will find answers to Drap and Drop Questions

Question 1

Drag the term Gateway and drop it into the locations that require a voice gateway




Question 2



London, United Kingdom:

+ CAS E1
+ 2.048 Mbps
+ 30 voice channels
+ out-of-ban signaling in timeslot 17

Chicago, United States:

+ CAS T1
+ 1.544 Mbps
+ RBS in-band
+ 24 voice channels

Question 3

Click and drag the protocol on the left to the matching characteristic on the right. Not all options will be used.




+ H.323



Question 4

Drag the correct length arrow(s) that represent call legs and drop them into the proper position to show how call leg(s) are used in a call. Arrows can be used more than once, and not all may apply.




Question 5

Drag the correct Call Leg and drop it in the proper position to provide call setup in both directions. Arrows may be used more than once , and not all may apply.




Question 6

Place the steps for inbound dial-peer matching in the correct order



1) Look for the incoming called-number command in the dial peer that matches the called number or DNIS string in the inbound call leg.
2) Look for the answer-address command in a dial peer that matches the calling number or ANI string of the inbound call leg.
3) Look for the destination-pattern command in a dial peer that matches the calling number or ANI string of the incoming call leg.
4) Look for the POTS dial peer port configuration that matches the voice port associated with the incoming call (POTS dial peers only).
5) If no matches are found, the system uses the default dial peer.

Question 7

Three tasks are necessary to configure IP addressing for Cisco Unity Express hardware. The phrase that begins the statement for these tasks is on the right. Click and drag the phrase from the left to the box on the right that correctly completes the statement for each task.



– Configure the service engine interface: with a static IP address or IP address
– Configure the service-module IP address: to be on the same subnet as the router
– Configure the Cisco Unity Express IP default gateway: to be the same as the service engine

Question 8

Click and drag the description on the left to the signaling type it corresponds to on the right. Not all may apply.



1) Address Signaling: digits dialed or called party number that can be system -specific or variant-specific.
2) Supervisory Signaling: events that occur on the trunk, including seizure, wink, and answer.
3) Informational Signaling: tones such as ringing or busy and announcements such as “no longer in service”.

Question 9

Drag the steps for converting analog signals to digital signals.



Step 1:  Sampling
Step 2: Quantization
Step 3: Encoding
Step 4: Compression (optional)


Below is a summary for each step:

1) Sampling: The sampling rate must be at least twice the highest frequency, to accurately represent the original signal.
2) Quantization: consists of a scale made up of 8 major divisions or chords. Each chord is subdivided into 16 equally spaced steps. The chords are not equally spaced but are actually finest near the origin.
3) Encoding: encode the value into an 8-bit digital form.
4) Compression: compress the samples to reduce bandwidth. Although not required but it is widely used.
