Which of the following would be BEST to use to detect a MAC spoofing attack?
- A . Internet Control Message Protocol
- B . Reverse Address Resolution Protocol
- C . Dynamic Host Configuration Protocol
- D . Internet Message Access Protocol
Suggested Answer: B
Explanation:
Reverse Address Resolution Protocol (RARP) is a protocol that allows a device to obtain its MAC address from its IP address. A MAC spoofing attack is an attack where a device pretends to have a different MAC address than its actual one. RARP can be used to detect a MAC spoofing attack by comparing the MAC address obtained from RARP with the MAC address obtained from other sources, such as ARP or DHCP.

A technician receives feedback that some users are experiencing high amounts of jitter while using the wireless network. While troubleshooting the network, the technician uses the ping command with the IP address of the default gateway and verifies large variations in latency. The technician thinks the issue may be interference from other networks and non-802.11 devices.
Which of the following tools should the technician use to troubleshoot the issue?
- A . NetFlow analyzer
- B . Bandwidth analyzer
- C . Protocol analyzer
- D . Spectrum analyzer
Suggested Answer: D
Explanation:
A spectrum analyzer is a tool that measures the frequency and amplitude of signals in a wireless network. It can be used to troubleshoot issues related to interference from other networks and non-802.11 devices, such as microwave ovens or cordless phones, by identifying the sources and levels of interference in the wireless spectrum. A spectrum analyzer can also help to optimize the channel selection and placement of wireless access points.

Wireless users are reporting intermittent internet connectivity. Connectivity is restored when the users disconnect and reconnect, utilizing the web authentication process each time. The network administrator can see the devices connected to the APs at all times.
Which of the following steps will MOST likely determine the cause of the issue?
- A . Verify the session time-out configuration on the captive portal settings
- B . Check for encryption protocol mismatch on the client’s wireless settings
- C . Confirm that a valid passphrase is being used during the web authentication
- D . Investigate for a client’s disassociation caused by an evil twin AP
Suggested Answer: A
Explanation:
A captive portal is a web page that requires users to authenticate before they can access the internet. If the session time-out configuration is too short, users may experience intermittent internet connectivity and have to reconnect using the web authentication process each time. The network administrator can verify the session time-out configuration on the captive portal settings and adjust it if needed.

Which of the following attacks did the network administrator prevent?
- A . Evil twin
- B . Tailgating
- C . Piggybacking
- D . Shoulder surfing
Suggested Answer: B
Explanation:
Tailgating is a physical security attack where an unauthorized person follows an authorized person into a restricted area without proper identification or authorization. The network administrator prevented this attack by stopping and directing the person to the security desk.

A network is experiencing a number of CRC errors during normal network communication.
At which of the following layers of the OSI model will the administrator MOST likely start to troubleshoot?
- A . Layer 1
- B . Layer 2
- C . Layer 3
- D . Layer 4
- E . Layer 5
- F . Layer 6
- G . Layer 7
Suggested Answer: A
Explanation:
CRC errors are cyclic redundancy check errors that occur when data is corrupted during transmission. CRC errors are usually caused by physical layer issues such as faulty cables, connectors, ports, or
interference. The network administrator will most likely start to troubleshoot at layer 1 of the OSI model, which is the physical layer that deals with the transmission of bits over a medium.

Client devices cannot enter a network, and the network administrator determines the DHCP scope is exhausted. The administrator wants to avoid creating a new DHCP pool.
Which of the following can the administrator perform to resolve the issue?
- A . Install load balancers
- B . Install more switches
- C . Decrease the number of VLANs
- D . Reduce the lease time
Suggested Answer: D
Explanation:
To resolve the issue of DHCP scope exhaustion without creating a new DHCP pool, the administrator can reduce the lease time. By decreasing the lease time, the IP addresses assigned by DHCP will be released back to the DHCP scope more quickly, allowing them to be assigned to new devices.

An administrator is writing a script to periodically log the IPv6 and MAC addresses of all the devices on a network segment.
Which of the following switch features will MOST likely be used to assist with this task?
- A . Spanning Tree Protocol
- B . Neighbor Discovery Protocol
- C . Link Aggregation Control Protocol
- D . Address Resolution Protocol
Suggested Answer: B
Explanation:
Short. The switch feature that is most likely to be used to assist with logging IPv6 and MAC addresses of devices on a network segment is Neighbor Discovery Protocol (NDP). NDP is used by IPv6 to discover and maintain information about other nodes on the network, including their IPv6 and MAC addresses. By periodically querying NDP, the administrator can log this information for auditing purposes.

- A . AAAA
- B . CNAME
- C . MX
- D . SOA
Suggested Answer: B
Explanation:
The DNS record that works as an alias to another record is called CNAME (Canonical Name). CNAME records are used to create an alias for a domain name that points to another domain name.

A company built a new building at its headquarters location. The new building is connected to the company’s LAN via fiber-optic cable. Multiple users in the new building are unable to access the company’s intranet site via their web browser, but they are able to access internet sites.
Which of the following describes how the network administrator can resolve this issue?
- A . Correct the DNS server entries in the DHCP scope
- B . Correct the external firewall gateway address
- C . Correct the NTP server settings on the clients
- D . Correct a TFTP Issue on the company’s server
Suggested Answer: A
Explanation:
If multiple users in a new building are unable to access the company’s intranet site via their web browser but are able to access internet sites, the network administrator can resolve this issue by correcting the DNS server entries in the DHCP scope. The DHCP scope is responsible for assigning IP addresses and DNS server addresses to clients. If the DNS server entries are incorrect, clients will not be able to access intranet sites.
Reference: CompTIA Network+ Certification Study Guide, Exam N10-007, Fourth Edition, Chapter 4: Network Implementations, Objective 4.4: Explain the purpose and properties of DHCP.

A technician is installing a new fiber connection to a network device in a datacenter. The connection from the device to the switch also traverses a patch panel connection.
The chain of connections is in the following order:
Device
LC/LC patch cable
Patch panel
Cross-connect fiber cable
Patch panel
LC/LC patch cable
Switch
The connection is not working. The technician has changed both patch cables with known working patch cables. The device had been tested and was working properly before being installed.
Which of the following is the MOST likely cause of the issue?
- A . TX/RX is reversed
- B . An incorrect cable was used
- C . The device failed during installation
- D . Attenuation is occurring
Suggested Answer: A
Explanation:
The most likely cause of the issue where the fiber connection from a device to a switch is not working is that the TX/RX (transmit/receive) is reversed. When connecting fiber optic cables, it is important to ensure that the TX of one device is connected to the RX of the other device and vice versa. If the TX/RX is reversed, data cannot be transmitted successfully.
Reference: CompTIA Network+ Certification Study Guide, Exam N10-007, Fourth Edition, Chapter 5: Network
Operations, Objective 5.1: Given a scenario, use appropriate documentation and diagrams to manage the network.
