Question 1

Refer to the exhibit.

What information can be gleaned from the output of the show ephone command?

A. There are two registered IP phones. Shared number 5010 on line 2. Message waiting on line 1 of phone 1.
B. There are two registered IP phones. Shared number 5010 on line 2. Message waiting on shared line.
C. There are two IP phones. Phone 2 is unregistered. Shared number 5010 on line 2. Message waiting on shared line.
D. There are two IP phones. Phone 2 is unregistered. Shared number 5010 on line 2. Message waiting on line 1 of phone 1.
E. There are two IP phones. Phone 2 is unregistered. Shared number 5010 on line 2 of phone 2. Message waiting on line 2 of phone 1.
Answer: D

Explanation:

The first Ephone's status (ephone-1) is REGISTERED so we can confirm this ephone has been registered. The second one (ephone-2) shows DECEASED, it means that the CME router has lost connectivity with this IP Phone through a TCP keepalive failure.

Notice: The status UNREGISTERED indicates the CME router closed the connection to the IP phone in a normal manner.

Question 2

Question 3

Refer to the exhibit.

When a call is placed to 2000, phones 1 and 2 are paged. A call to 2001 pages phones 3 and 4.
What command is missing so that a call to 2002 pages all four phones?

A. Paging group 20 21
B. Paging group 10 20 30 40
C. Paging group all
D. Paging group 2000 2001 2002
E. Paging group ephones-all

Answer: A

Explanation:

In fact, the exhibit should show the configuration of ephone-dn 20, something like this:

ephone-dn 20
number 2000
paging ip 239.0.1.21 port 2000

To page all four phones which belong to group 20 & 21, we just need to assign these two groups to a number. The full command is:

CME_Voice(config-ephone-dn)# paging group 20,21

Notice:

- We don't need to assign any ephones to paging-dn 22 because this ephone-dn represents a group of both paging-dns 20 and 21.

- The IP address that follows the paging command is a multicast address.

Question 4

Which ephone-dn type does the exhibit represent?

A. Shared ephone-dn
B. Overlaid ephone-dn
C. Dual-line ephone-dn
D. Single-line ephone-dn
E. Dual-number ephone-dn
F. Two ephone-dns with one number

Answer: A

Explanation:

Shared line (or shared ephone-dn) means that we assign the same ephone-dn to multiple ephones. Incoming calls to number 1006 will ring on both phones.
