Refer to the exhibit. Which type of route does R1 use to reach host 10.10.13.10/32?
R1 uses a network route to reach host 10.10.13.10/32. The routing table contains a route to the network 10.10.13.0/25, which means it can reach any host within the 10.10.13.0 network, including 10.10.13.10. The subnet mask /25 indicates that this route is intended for the entire subnet, not just a single host, confirming that it is a network route.
Refer to the exhibit. Which prefix does Router1 use for traffic to Host A?
Router1 will use the prefix 10.10.13.208/29 for traffic to Host A (10.10.13.214). This is because the /29 subnet mask provides the most specific match for this IP address. Specifically, the 10.10.13.208/29 prefix includes IP addresses from 10.10.13.208 to 10.10.13.215, which encompasses the IP address of Host A. In routing, the most specific match (longest prefix) is always chosen to ensure efficient routing. Therefore, 10.10.13.208/29 is the correct prefix.

A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two.)
AD
Whenever the physical transmission has problems, the receiving device might receive a frame whose bits have changed values. These frames do not pass the error detection logic as implemented in the FCS field in the Ethernet trailer. The receiving device discards the frame and counts it as some kind of input error.
Cisco switches list this error as a CRC error. Cyclic redundancy check (CRC) is a term related to how the FCS math detects an error.
The ג€input errorsג€ includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts.

This subnet question requires us to grasp how to subnet very well. To quickly find out the subnet range, we have to find out the increment and the network address of each subnet. Let's take an example with the subnet 172.28.228.144/18:
From the /18 (= 1100 0000 in the 3rd octet), we find out the increment is 64. Therefore the network address of this subnet must be the greatest multiple of the increment but not greater than the value in the 3rd octet (228). We can find out the 3rd octet of the network address is 192 (because 192 = 64 * 3 and 192 < 228) -
> The network address is 172.28.192.0. So the first usable host should be 172.28.192.1 and it matches with the 5th answer on the right. In this case we don't need to calculate the broadcast address because we found the correct answer.
Let's take another example with subnet 172.28.228.144/23 -> The increment is 2 (as /23 = 1111 1110 in 3rd octet) -> The 3rd octet of the network address is 228
(because 228 is the multiply of 2 and equal to the 3rd octet) -> The network address is 172.28.228.0 -> The first usable host is 172.28.228.1. It is not necessary but if we want to find out the broadcast address of this subnet, we can find out the next network address, which is 172.28.(228 + the increment number).0 or
172.28.230.0 then reduce 1 bit -> 172.28.229.255 is the broadcast address of our subnet. Therefore the last usable host is 172.28.229.254.
