Review Routing Tables:
Check the routing tables of Router A, Router B, and Router C to identify any missing routes.
Identify Missing Routes:
Ensure that each router has routes to the networks on which Workstation A and File Server 2 are located.
Add Static Routes:
If a route is missing, add a static route to the relevant destination network via the correct interface.
Routing Table:
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
S* 0.0.0.0/0 is directly connected, GigabitEthernet3
A network administrator is configuring a wireless network with an ESSID.
Which of the following is a user benefit of ESSID compared to SSID?
- A . Stronger wireless connection
- B . Roaming between access points
- C . Advanced security
- D . Increased throughput
B
Explanation:
An Extended Service Set Identifier (ESSID) allows multiple access points to share the same SSID, enabling seamless roaming for users. This means that users can move between different access points within the same ESSID without losing connection or having to reauthenticate. This provides a better user experience, especially in large environments such as office buildings or campuses.
Reference: CompTIA Network+ study materials.
A network technician sets up a computer on the accounting department floor for a user from the marketing department. The user reports that they cannot access the marketing department’s shared drives but can access the internet.
Which of the following is the most likely cause of this issue?
- A . Mismatched switchport duplex
- B . Misconfigured gateway settings
- C . Incorrect VLAN assignment
- D . SVI is assigned to the wrong IP address
C
Explanation:
The user’s inability to access the marketing department’s shared drives, despite having internet access, suggests a network segmentation issue. The most likely cause is an incorrect VLAN assignment. The computer is physically located on the accounting department floor, and the switchport is likely configured for the accounting VLAN, not the marketing VLAN. VLANs segment network traffic, and if the computer is in the wrong VLAN, it cannot communicate with the marketing department’s resources.
Why not Mismatched switchport duplex? Duplex mismatches cause performance issues (e.g., packet loss) but not specific access denials to shared drives.
Why not Misconfigured gateway settings? Incorrect gateway settings would prevent internet access, which the user has.
Why not SVI is assigned to the wrong IP address? A Switch Virtual Interface (SVI) with an incorrect IP address affects inter-VLAN routing, but this would likely impact multiple users, not just one.
Reference: CompTIA Network+ N10-009 Objective 2.2: Explain the purpose of network segmentation and VLAN configuration. The CompTIA Network+ Study Guide (e.g., Chapter 6: Switching) explains that VLANs isolate traffic, and incorrect VLAN assignments prevent access to resources on other VLANs.
Which of the following devices can operate in multiple layers of the OSI model?
- A . Hub
- B . Switch
- C . Transceiver
- D . Modem
B
Explanation:
Understanding Switches:
Layer 2 (Data Link Layer): Traditional switches operate primarily at Layer 2, where they use MAC addresses to forward frames within a local network.
Layer 3 (Network Layer): Layer 3 switches, also known as multilayer switches, can perform routing functions using IP addresses to forward packets between different networks.
Capabilities of Multilayer Switches:
VLANs and Inter-VLAN Routing: Multilayer switches can handle VLAN (Virtual Local Area Network) configurations and perform inter-VLAN routing, enabling communication between different VLANs.
Routing Protocols: They can run routing protocols like OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol) to manage traffic between networks.
Comparison with Other Devices:
Hub: Operates only at Layer 1 (Physical Layer) and simply repeats incoming signals to all ports.
Transceiver: Also operates at Layer 1, converting electrical signals to optical signals and vice versa.
Modem: Primarily operates at Layer 1 and Layer 2, modulating and demodulating signals for transmission over different types of media.
Practical Application:
Multilayer switches are commonly used in enterprise networks to optimize performance and manage complex routing and switching requirements within a single device.

SIMULATION
You have been tasked with setting up a wireless network in an office. The network will consist of 3
Access Points and a single switch.
The network must meet the following parameters:
The SSIDs need to be configured as CorpNet with a key of S3cr3t!
The wireless signals should not interfere with each other
The subnet the Access Points and switch are on should only support 30 devices maximum
The Access Points should be configured to only support TKIP clients at a maximum speed
INSTRUCTONS
Click on the wireless devices and review their information and adjust the settings of the access points to meet the given requirements.

A university is implementing a new campus wireless network. A network administrator needs to configure the network to support a large number of devices and high-bandwidth demands from students.
Which of the following wireless technologies should the administrator consider for this scenario?
- A . Bluetooth
- B . Wi-Fi 6E
- C . 5G
- D . LTE
B
Explanation:
Wi-Fi 6E is the best choice for high-density environments, such as a university campus. It:
Supports more devices with OFDMA (Orthogonal Frequency-Division Multiple Access)
Uses the 6GHz band, reducing congestion
Provides faster speeds and lower latency
This makes Wi-Fi 6E ideal for large networks with high-bandwidth demands, like those in a university setting.

Which of the following is the correct order of components in a bottom-up approach for the three-tier hierarchical model?
- A . Access, distribution, and core
- B . Core, root, and distribution
- C . Core, spine, and leaf
- D . Access, core, and roof
A
Explanation:
The three-tier hierarchical model in network design consists of three layers: access, distribution, and core. The access layer is where devices like PCs and printers connect to the network. The distribution layer aggregates the data received from the access layer switches before it is transmitted to the core layer, which is responsible for high-speed data transfer and routing. This approach improves scalability and performance in larger networks.
