A. APIPA address

B. Rogue DHCP server

C. Unreachable DNS server

D. Incorrect NAT settings

Correct Answer: D

Question 2:

SIMULATION

A network administrator receives a ticket stating there is a connectivity issue between the server and the storage devices. The administrator needs to identify any issues and implement the appropriate solutions.

INSTRUCTIONS

Click on each access and core switch. Enter commands into the terminal to identify any problems and select the appropriate resolutions. Type help in each terminal to view a list of available commands.

If at any time you would like to bring back the initial state of the simulation, please click the Reset All button.

Correct Answer:

Question 3:

Which of the following attacks can cause users who are attempting to access a company website to be directed to an entirely different website?

A. DNS poisoning

B. Denial-of-service

C. Social engineering

D. ARP spoofing

Correct Answer: A

Network segmentation involves dividing a network into smaller segments or subnets. This is particularly important when integrating OT (Operational Technology) devices to ensure that these devices are isolated from other parts of the network.

Segmentation helps protect the OT devices from potential threats and minimizes the impact of any security incidents. It also helps manage traffic and improves overall network performance.

Question 4:

After HVAC failures caused network outages, the support team decides to monitor the temperatures of all the devices. The network administrator cannot find a command that will display this information. Which of the following will retrieve the necessary information?

A. SNMP OID values

B. NetFlow data export

C. Network baseline configurations

D. Security information and event management

Correct Answer: A

The network administrator can use the Simple Network Management Protocol (SNMP) to monitor the temperatures of all the devices. SNMP is a widely-used protocol for managing and monitoring network devices, such as routers, switches, servers, and other networking equipment.

SNMP allows network administrators to gather information about the performance and status of devices on the network, including temperature readings. To retrieve the temperature information, the administrator will have to configure SNMP on the devices and configure SNMP manager software on their computer.

Once the SNMP manager software is configured, it will be able to send SNMP requests to the devices and retrieve information such as temperature, voltage, fan speeds, etc. Many network devices have built-in SNMP support, and the administrator may also need to install SNMP agent software on the devices to enable SNMP monitoring.

The administrator can also use some specific command or tool like IPMI (Intelligent Platform Management Interface) or DCIM (Data Center Infrastructure Management) tools for monitoring the temperatures of all the devices.

Question 5:

Which of the following OSI model layers will ensure messages are transmitted to their destinations and no data is duplicated?

A. Session

B. Data link

C. Network

D. Transport

Correct Answer: D

The transport layer is the fourth layer of the OSI model, and it is responsible for end-to-end delivery of data over a network.

It uses standard protocols such as TCP, UDP, and DCCP to enhance its functionalities. One of the main functions of the transport layer is to ensure that messages are transmitted to their destinations reliably and in the correct order. It also prevents data duplication by using sequence numbers, acknowledgments, and retransmission mechanisms

Question 6:

A network technician wants to identify which DNS servers a computer is configured to use. Which of the following commands should the technician use?

A. nbtstat

B. arp

C. nslookup

D. netstat

Correct Answer: C

Question 7:

Which of the following demarcation connections would be MOST appropriate to use with a cable modem being installed in a SOHO situation?

A. RG6

B. Cat 6

C. RJ11

A network deployment engineer is deploying a new single-channel 10G optical connection. Which of the following optics should the engineer MOST likely use to satisfy this requirement?

A. QSFP

B. QSFP+

C. SFP

D. SFP+

Correct Answer: D

SFP+ is a type of optical transceiver that supports 10G single-channel transmission over fiber optic cables. SFP+ stands for small form-factor pluggable plus, and it is compatible with SFP slots on switches and routers.

B. 255.255.255.192

C. 255.255.255.224

D. 255.255.255.240

Correct Answer: D

Reference: CompTIA Network+ Certification Exam Objectives – IP Addressing section.

Question 12:

A network administrator is in the process of installing 35 PoE security cameras. After the administrator installed and tested the new cables, the administrator installed the cameras. However, a small number of the cameras do not work. Which of the following is the most reason?

A. Incorrect wiring standard

B. Power budget exceeded

C. Signal attenuation

D. Wrong voltage

Correct Answer: B

When installing multiple Power over Ethernet (PoE) devices like security cameras, it is crucial to ensure that the total power requirement does not exceed the power budget of the PoE switch. Each PoE switch has a maximum power capacity,

and exceeding this capacity can cause some devices to fail to receive power. PoE Standards: PoE switches conform to standards such as IEEE 802.3af (PoE) and 802.3at (PoE+), each with specific power limits per port and total power capacity.

Power Calculation: Adding up the power requirements of all connected PoE devices can help determine if the total power budget of the switch is exceeded. Symptoms: When the power budget is exceeded, some devices, typically those farthest from the switch or connected last, may not power up or function correctly.

Question 13:

Which of the following would a network administrator configure to set NTP settings for a specific subnet within DHCP?

A. Reservation

B. Lease time

C. Scope options

D. Exclusion range

Correct Answer: C

Question 14:

A network administrator is preparing new switches that will be deployed to support a network extension project. The lead network engineer has already provided documentation to ensure the switches are set up properly. Which of the following did the engineer most likely provide?

A. Physical network diagram

B. Site survey reports

C. Baseline configurations

D. Logical network diagram

Correct Answer: D

Question 15:

A network engineer configures a new switch and connects it to an existing switch for expansion and redundancy. Users immediately lose connectivity to the network. The network engineer notes the following spanning tree information from both switches:

Switch 1

Port State Cost 1 Forward 2 2 Forward 2

Switch 2

Port State Cost 1 Forward 2 2 Forward 2

Which of the following best describes the issue?

A. The port cost should not be equal.

B. The ports should use link aggregation.

C. A root bridge needs to be identified.

D. The switch should be configured for RSTP.

Correct Answer: C

The issue is that no root bridge has been identified. In STP, a root bridge is necessary to manage redundant paths and avoid loops in the network. Without a root bridge, all switches will assume they can forward traffic, causing a network loop and connectivity problems.
