Answer:
A. A1
Explanation:
Worksheet's Columns are named with Alphabets. i.e. A,B,C,D,E....
And Worksheet's rows are named with numbers. i.e. 1,2,3,4,5....
So the intersection of first row number as "1" and First Column name as "A" is A1 as worksheet displays column name first and then row number.

If a router tried to match a packet sourced from IP address 1.1.1.1 using this ACL, the first statement will be used.
a. First
<u>Explanation:</u>
We use ACL technology to make basic security level in the network. ACL is strictly used to update the routing in the network and make sure network pears and make sure the flow control for network traffic is followed.
Since it is routing ip address through ACL statement. It all depends on how the network engineer routed the traffic in the network. A packet with source IP address 1.1.1.1 would match any of the three explicitly configured commands described in the question. As a result, the first statement will be used.
The router searches the ACL statement by order and when the match is found it stops execution of the ACL statement that will match with the first occurrence.
A PCM system consists of a PCM encoder (transmitter) and a PCM decoder (receiver). The essential operations in the PCM transmitter are sampling, quantizing and encoding. All the operations are usually performed in the same circuit called as analog-to digital convert Early electrical communications started to sample signals in order to multiplex samples from multiple telegraphy sources and to convey them over a single telegraph cable. The American inventor Moses G. Farmer conveyed telegraph time-division multiplexing (TDM) as early as 1853. Electrical engineer W. M. Miner, in 1903, used an electro-mechanical commutator for time-division multiplexing multiple telegraph signals; he also applied this technology to telephony.
