Question 1:
A senior network administrator has told you that you will be assigning internet-facing systems (e.g. your web server, mail exchange server, etc) an IP address from the public Class B space that the company has. The network administrator tells you to identify in a diagram what that space will be from the list of IP spaces he keeps a record of.
His record shows the following spaces are available:
173.24.0.0/16
191.16.24.0/24
172.24.0.0/16
192.168.0.0/16
Select which is the IP space the senior network administrator wants you to use to assign to internet-facing systems.
A.192.168.0.0/16
B.173.24.0.0/16
C.172.24.0.0/16
D.191.16.24.0/24
Question 2:
SCENARIO: You are responsible for configuring DHCP for a LAN in the environment. You are given a local area network with the IP address space of 192.168.10.0/24(subnet 255.255.255.0). As you configure the DHCP server to issue out network settings to workstations and servers on the LAN, you need to identify a default gateway for the systems.
Which IP address would you assign as the default gateway?
A.192.168.11.1
B.192.168.10.1
C.192.168.10.0
D.192.168.10.255
Question 3:
SCENARIO: You are finding that your network is not passing internal traffic due to a packet from the origin system having a destination IP that the network infrastructure is unaware of. You need to let the network know about that IP space in the network.
Which network component needs to be configured to know of the IP space so that packets can complete movement from the origin system to the destination system?
A. Bridge
B. Switch
C. Router
Question 4:
You are troubleshooting a network experiencing frequent packet collisions. Which of the following is the most likely cause of packet collisions in an Ethernet network?
A. Faulty network cables
B. Network congestion due to high traffic
C. Incorrect IP address configuration
D. All network interfaces are set to full duplex
Question 5:
Which of the following actions is most effective in reducing network congestion?
A.Implementing VLANs to segment network traffic
B.Increasing the IP address range of the network
C.Changing the subnet mask of the network
D.Upgrading to higher capacity network cables (e.g., from Cat5e to Cat6)
Question 6:
SCENARIO: You are in a conversation about network traffic management and prioritization. You notice the seasoned network administrators are talking about Quality of Service (QoS) in the network. You understand that they wish to implement QoS capabilities for WHICH ONE of the four potential below reasons?
A.To automatically block all non-essential traffic and allow only essential applications to run
B. To prioritize network traffic, ensuring critical applications receive the necessary bandwidth and low latency.
C. To increase the overall bandwidth capacity of the network.
D. To ensure that all network devices operate at maximum speed regardless of the type of traffic
