Which OSI layer is associated with the following: The acknowledgement of transmissions, sequencing, and flow control across a network?()
You are the network administrator of a small Layer 2 network with 50 users. Lately, users have been complaining that the network is very slow. While troubleshooting, you notice that the CAM table of your switch is full, although it supports up to 12,000 MAC addresses. How can you solve this issue and prevent it from happening in the future?()
A transport layer protocol has several responsibilities, One is to create a process-to-process (program-to-program) communication; TCP uses port (1) to accomplish this. Another responsibility of a transport layer protocol is to create a (2) and error-control mechanism at the transport level. TCP uses a sliding (3) protocol to achieve flow control. It uses the acknowledgment packet, time-out, and retransmission to achieve (4) control. The transport layer is also responsible for providing a connection mechanism for the application program. The application program sends (5) of data to the transport layer. It is the responsibility of the transport layer at the sending station to make a connection with the receiver. 空白(5)处应选择()

Which three statements accurately describe layer 2 Ethernet switches?()
In the three-layer hierarchical network design model;what’s associated with the access layer?()
Which three Layer 2 encapsulation types would be used on a WAN rather than a LAN?()
Which three statements accurately describe layer 2 Ethernet switches?()
Refer to the exhibit. The Layer 2 network uses VTP to manage its VLAN database. A network designer created all VLANs on the VTP server (switch 1) and it has been advertised through VTP to all other VTP clients (switches 2 through 4). Due to network growth,a network operator decided to add a new switch between switch 1 and switch 3. The network operator has been instructed to use a refurbished switch and use a VTP client. Which three of these factors should the network operator consider to minimize the impact of adding a new switch?()
As a frame leaves a Layer 3 device, the Layer 2 encapsulation information is changed from what it was when it entered the devicE.For what two reasons can this happen? ()
