Question 1 of 741

A technician needs to limit the amount of broadcast traffic on a network and allow different segments to communicate with each other.

Which of the following options would satisfy these requirements?

Answer

Suggested Answer

The suggested answer is B.

The correct choice is to add a layer 3 switch and create a VLAN. VLANs (Virtual Local Area Networks) allow for logical segmentation of a network, where each VLAN acts as its own broadcast domain, thereby reducing broadcast traffic. A layer 3 switch is capable of routing between these VLANs, thus allowing different network segments to communicate with each other. While routers and layer 3 switches both handle inter-VLAN routing, a layer 3 switch is specifically designed for this purpose in a switched network environment.

Question 2 of 741

The network install is failing redundancy testing at the MDF. The traffic being transported is a mixture of multicast and unicast signals.

Which of the following would BEST handle the rerouting caused by the disruption of service?

Answer

Suggested Answer

The suggested answer is A.

The question states that the traffic being transported is a mixture of multicast and unicast signals. There are three basic types of network transmissions: broadcasts, which are packets transmitted to every node on the network; unicasts, which are packets transmitted to just one node; and multicasts, which are packets transmitted to a group of nodes. Multicast is a layer 3 feature of IPv4 & IPv6. Therefore, we would need a layer 3 switch (or a router) to reroute the traffic.
Unlike layer 2switches that can only read the contents of the data-link layer protocol header in the packets they process, layer 3 switches can read the (IP) addresses in the network layer protocol header as well.
Question 3 of 741

Which of the following network devices use ACLs to prevent unauthorized access into company systems?

Answer

Suggested Answer

The suggested answer is B.

A firewall is a system designed to prevent unauthorized access to or from a private network. Firewalls are frequently used to prevent unauthorized Internet users from accessing private networks connected to the Internet, especially intranets. Firewalls use ACLs (access control lists) to determine which traffic is allowed through the firewall. All traffic entering or leaving the intranet passes through the firewall, which examines each message and blocks or allows the message depending on rules specified in the ACL. The rules in the ACL specify which combinations of source IP address, destination address in IP port numbers are allowed.
Question 4 of 741

Which of the following is used to define how much bandwidth can be used by various protocols on the network?

Answer

Suggested Answer

Traffic shaping is used to define how much bandwidth can be allocated to different protocols on the network. By prioritizing certain types of traffic and delaying others, it ensures that the network bandwidth is used efficiently, optimizing the performance of critical applications.

Question 5 of 741

Which of the following is used to authenticate remote workers who connect from offsite? (Select TWO).

Answer

Suggested Answer

The suggested answer is D, E.

To authenticate remote workers who connect from offsite, RADIUS and 802.1x are commonly used. RADIUS is a protocol that centralizes authentication, authorization, and accounting for users accessing a network. It is often employed by ISPs and enterprises to manage remote access. 802.1x is a standard for network access control that provides an authentication mechanism for devices wishing to connect to the network, ensuring that only authenticated clients can access the network resources. These two options complement each other in providing secure authentication for remote users.
