Which two statements about VTP are true? (Choose two.)
Answer: AE
"All switches in a VTP domain must have the same domain name, but they do not need to run the same VTP version."https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3560/software/release/12-2_52_se/configuration/guide/3560scg/swvtp.html#wp1107364 A&D are correct

Which type does a port become when it receives the best BPDU on a bridge?
Answer: D
Ref: Understanding Rapid Spanning Tree Protocol (802.1w) – Cisco “... Port Roles Root Port Roles • The port that receives the best BPDU on a bridge is the root port. ...” A. The designated port Wrong answer. B. The backup port Wrong answer. C. The alternate port Wrong answer. D. The root port Correct answer.

Which value can you modify to configure a specific interface as the preferred forwarding interface?
Answer: B
B: Port priority Well, C is tricky. It says "VLAN priority". However, there is no thing called VLAN priority. The correct term is "port priority for certain VLAN/ VLANs. You can adjust port priority without reference to any VLAN which makes it the priorityi of the port for all VLANa. Spanning-Tree port-priority value Else, You can adjust port priority wih reference to VLAN / VLANs which makes it the priority of the port for that specific VLAN/ VLANs Spanning-Tree vlan value/range port-priority value

Which statement about Cisco Discovery Protocol is true?
Answer: A
Not C Because the option doesn't specifically say from Cisco router, switches, etc. Not D because it does operate on the data-link layer but Not on the physical layer.

What occurs to frames during the process of frame flooding?
Answer: C
Ref: Flooding vs Broadcast - Cisco Community Post by Kristian Alexander Brown “… Flooding is sometimes known as an unknown unicast. This happens when a switch receives a frame with a destination mac address it does not have in the CAM table. It will flood it out all ports except the receiving port of the frame. …” A. Frames are sent to all ports, including those that are assigned to other VLANs. Wrong answer. B. Frames are sent to every port on the switch that has a matching entry in MAC address table. Wrong answer. C. Frames are sent to every port on the switch in the same VLAN except from the originating port. Correct answer. D. Frames are sent to every port on the switch in the same VLAN. Wrong answer.

What are two reasons a network administrator would use CDP? (Choose two.)
Answer: DE
Two reasons a network administrator would use CDP (Cisco Discovery Protocol) are: C. To obtain VLAN information from directly connected switches: CDP can provide information about the directly connected switches, including their device type, platform, and VLAN information. This can be helpful for understanding the network topology and configuration. D. To verify Layer 2 connectivity between two devices when Layer 3 fails: CDP can be used to verify the physical and data link layer connectivity between two Cisco devices. When Layer 3 connectivity fails, CDP can help in identifying and diagnosing Layer 2 issues that may be causing the problem. The other options (A, B, E, F) do not directly relate to the typical use cases of CDP.

What are two benefits of using VTP in a switching environment? (Choose two.)
Answer: CE
Ref: Understanding VLAN Trunk Protocol (VTP) – Cisco “... Introduction VLAN Trunk Protocol (VTP) reduces administration in a switched network. When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. ...” A. It allows switches to read frame tags. Wrong answer. B. It allows ports to be assigned to VLANs automatically. Wrong answer. C. It maintains VLAN consistency across a switched network. Correct answer. D. It allows frames from multiple VLANs to use a single interface. Wrong answer. E. It allows VLAN information to be automatically propagated throughout the switching environment. Correct answer.

Which three statements are typical characteristics of VLAN arrangements? (Choose three.)
Answer: BDE
To communicate between two different VLANs we need to use a Layer 3 device like router or Layer 3 switch -> B is correct. VLANs don’t affect the number of collision domains, they are the same -> C is not correct. Typically, VLANs increase the number of broadcast domains. We must use a different network (or sub-network) for each VLAN. For example we can use 192.168.1.0/24 for VLAN 1, 192.168.2.0/24 for VLAN 2 -> D is correct. A switch maintains a separate bridging table for each VLAN so that it can send frame to ports on the same VLAN only. For example, if a PC in VLAN 2 sends a frame then the switch look-ups its bridging table and only sends frame out of its ports which belong to VLAN 2 (it also sends this frame on trunk ports) -> E is correct.

On a corporate network, hosts on the same VLAN can communicate with each other, but they are unable to communicate with hosts on different VLANs. What is needed to allow communication between the VLANs?
Answer: A
A is correct. "For inter-VLAN communication, a layer 3 device (usually a router) is needed. This layer 3 device needs to have an IP address in each subnet (VLAN) and have a connected route to each of those subnets. The hosts in each subnet can use the router’s IP addresses as their default gateway."

Which statement about LLDP is true?
Answer: B
B is not correct because some LLDP parameters are configured at interface levels (transmit and receive) So it's not only configured at global configuration mode. Maybe the lack of the word "only" makes the answer correct. C is not correct because the update timer can be modified, but anyone could understand the word "fixed" like stating that the updates are sent steadily every a certain amount of 'fixed' time. I hate when they are not trying to measure your knowledge. Instead they're trying to trick you by using unclear questions!
