172.16.10.1 0.0.0.0 destination-port eq 21 is the correct statement? ()

sourceIP is 192.168.1.1, destination P is 172.16.10.1, and all TCP packets with destination port number
21 match this rule

The source IP is 192.168.1.1, the destination IP is 172.16.10.2, and all 1CP packets whose destination port number is 21 match this rule

Rule sourceIP is 192.168.1.1, the destination IP is 72.16.10.3, and all TCP packets with the destination port number of 21 match this rule

D. The type of ACL is basic ACL

NO.238 A company applies for a class C IP address for subnetting. It has eight branches, and the largest branch has a subnet that should support at least 14 hosts. What would be an appropriate subnet mask?

255.255.255.192

255.255.255.224

255.255.255.128

255.255.255.0

This explanation was already provided earlier. Please refer to queestion 13 at the start.

NO.239 What elements can NAPT convert? ()

Only MAC. address

Only IP address

NO.240 Which of the following statements about RA. and RS messages in IPv6 are correct? ()*

RA. Used to request address prefix information

RS is used to request address prefix information

RA. Used to reply address prefix information

RS is used to reply address prefix information

NO.241 What action does an access port take in the process of sending VLAN frames?

The access port sends tagged frames.

The access port strips the VLAN tag and forwards the frame.

The access port exchanges the VLAN tag of the inbound and outbound port of the frame before forwarding the frame.

The access port attaches its PVID information to the frame.

An access port is a switch port assigned to a single VLAN and used to connect end devices (such as PCs or printers).
* Access ports do not send VLAN tags. They remove the VLAN tag before forwarding frames to the connected device because most end devices do not support VLAN tagging.
* Option A (Incorrect): Tagged frames are sent only by trunk ports, not access ports.
* Option B (Correct): The access port strips the VLAN tag before forwarding the frame to ensure compatibility with non-VLAN-aware devices.
* Option C (Incorrect): VLAN tags are not exchanged between inbound and outbound ports.
* Option D (Incorrect): The access port does not attach PVID information to the frame when sending it out.
Thus, the correct answer is B.

NO.242 As shown in the figure below, are the following statements correct?

Host A can ping host B

The IP address masks of host A and host B are different, so host A and host B cannot communicate

NO.243 By default, on the broadcast networkOSPFWhat is the transmission period of the protocol HELLO message? ()

10s

40s

30s

NO.246 Assuming all STP enabled switches have the same bridge priority. The MAC address of switch A is 00-e0-fc-
00-00-40, the MAC address of switch B is 00-e0-fc-00-00-10, the MAC address of switch C is 00-e0-fc-00-
00-20, and the MAC address of switch D is 00-e0-fc-00-00-80. Which switch will be elected as the root switch?

Switch B

Switch A

Switch D

Switch C

Detailed Explanation:When bridge priorities are identical, STP elects the switch with the lowest MAC address as the root. Here, Switch B has the lowest MAC address (00-e0-fc-00-00-10), making it the root switch.
(Reference: HCIA-Datacom Training Material, STP Root Bridge Election)
