1. In what ways does WLAN differ from other technologies?
- The WLAN includes an access point (AP) which is employed to attach to the web AP sends and receives frequency signals to the connected devices
- It works with a bandwidth of two . 4 GHz (802.11b) or 5 GHZ (802.11 a)
- It gives a high data transfer rate.
2. What is meant by compliance in the industry?
Compliance may be achieved by conforming to established guidelines or specifications, or to the process of becoming so. In the case of software, for example, compliance may be achieved by following a standards body’s guidelines and then deployed by an organization in accordance with a vendor’s licensing agreement.
3. What do you know about BYOD access?
Employees using personal devices to access work-related systems and potentially sensitive or confidential data is called BYOD or Bring Your Own Device. Bringing your own device (BYOD) to work is a trend that allows you to use your personal devices to connect to the organizational network and access work-related systems.
4. Can you explain the meaning of authentication and encryption?
Encryption is the transformation of data into a form in which it cannot be accessed by someone lacking secret knowledge. Decryption is the process of transforming encoded—or encrypted— information back into a form that can be used. Authentication is the process of convincing a gatekeeper that you are who you say you are, typically by proving that you know a secret.
5. What are some of the most important WLAN design considerations?
- Size of Physical Location.
- Intended Use of the Wireless Network.
- The number of Wireless Devices.
- Wireless Client Device Capabilities.
- The Environment.
- Performance Expectations.
- Bring Your Own Device (BYOD) Acceptance.
- Building Age and Construction Materials.
6. What is meant by WLAN calling?
WLAN Call enables you to make calls via your WLAN (wireless local area network) for no additional monthly charge. You must have a contract with a VoLTE (voice over LTE)-enabled network, a smartphone that supports WLAN calls, and an internet connection.
7. What are three common constraints on a design?
- Time
- Scope
- Cost
8. How do you identify design constraints?
- Sort the constraints by type (e.g., hardware, software, procedure, algorithm).
- Each category should have a specific constraint
- Include the rationale corresponding to each requirement in the Requirements package.
9. Could you explain what is switch switching capacity?
Switch capacity is the maximum data-exchanging capability of a switch interface processor or the maximum capability between an interface card and a data bus. This ability is measured in gigabits per second, also called switching capacity.
10. Is DNS and DHCP the same server?
DHCP and DNS are two important services in IT networks. DHCP servers send addresses needed by network clients to communicate with other machines and services, while DNS servers make sure that machines, clients, and services can be found by name.
11. What are the three categories of site survey tools used in wireless networks?
- Passive
- Active
- Predictive
12. What is meant by an SSID profile?
SSID profiles help you to define the properties of your wireless network. To configure SSID profiles, select Configuration > Device Configuration > SSID Profiles.
13. What are the main objectives of channel assignment strategies?
The channel assignment strategy seeks to efficiently use the available spectrum. For efficient use, a frequency reuse scheme consistent with increasing capacity and reducing interference is required.
14. Could you elaborate on the AP on a Stick survey?
A tripod or other mounting options are used to place APs higher than the normal deployment height; this staging area is called an AP on a Stick survey, and the APs in this temporary position is used to predict the performance of your design.
15. What is predictive modeling software?
Predictive analytics software is used to identify trends and best practices in any industry. Marketing departments use this software to identify emerging customer bases. Financial and insurance companies use it to build risk assessment and fraud outlooks.
16. Could you explain the importance of pre-design planning?
Pre-design is important because it will deliver a plan for an extended return on investment, improved care, and increased recruitment and retention.
17. What is 802.11 R ft roaming?
Fast roaming, also known as IEEE 802.11r or Fast BSS Transition (FT), allows clients to quickly roam from one access point to another in WPA2 Enterprise-secured environments, by not having to re-authenticate with the RADIUS server every time it roams from one access point to another.
18. What does the Bill of Material BOM contain?
Some of the information in the bill of materials (BOM) includes the product code, part name, part number, part revision, description, quantity, unit of measure, size, length, weight, and specifications or features of the corresponding product.
19. How would you describe a controller-based AP?
Controller-based access points are also known as thin clients. They require a controller for centralized management and don’t need to be manually configured. They’re usually used in large environments.
20. What is the difference between access point and controller?
Stand-alone access points encrypt their own communication with the laptop or PC, while controller-based access points encrypt the entire connection between the PC, the access point, and the controller.
21. What is the purpose of a design document?
A design document is a written description of a software’s purpose, functions, features, and limitations. It is created so that members of a large team working on a project have a stable point of reference and can gauge how the project is going. A design document assures that the product meets the needs of its users.
22. What are the two main WLAN deployment types?
- Lightweight
- Autonomous systems
23. Could you explain how is wireless LAN implemented?
Wireless LAN implementation entails more than choosing the desired standard and selecting a security mechanism. Positioning of access points can have a greater impact on throughput than standards. Such factors as access point location, access point distance, and WLAN topology impact network efficiency.
24. How would you describe what is PoE?
Power over Ethernet (PoE) uses the same pairs of wires found in Cat5e and Cat6 networking cables to transfer small amounts of electricity to low-powered devices like web cameras, wireless access points, LED lights, and VOIP phones.
25. What is an RF survey?
Radiofrequency propagation surveys measure cellular and wireless transmissions—like those used by cell phones and wifi devices—to figure out where a mobile phone or wifi-enabled device was located at a particular time.
26. Which occurs more often ACI or CCI?
Adjacent channel interference occurs when transmissions are sent on an adjacent or partially overlapping channel. The noise and interference bleed over on the overlapping channel, and it is, therefore, a more serious problem than co-channel interference.
27. What is meant by the term RF output power?
Transmitter power output (TPO) is the amount of radiofrequency (RF) energy that a transmitter produces at its output, usually expressed in watts.
28. What are the reasons why misconfigurations can pose serious security risks?
When visibility into security risks is low, misconfiguration of security can open up new risks. For example, unnecessary administrative ports might be open for an application, which could expose the application to remote attacks.
29. What can be done to mitigate security misconfiguration?
- Developing a repeatable patching schedule.
- Keeping software up to date.
- Disabling default accounts.
- Encrypting data.
- Enforcing strong access controls.
- Providing admins with a repeatable process for avoiding overlooking items.
30. How does QoS affect network traffic?
Quality of service technologies enables network administrators to prioritize traffic according to the needs of specific applications. This gives administrators the ability to give bandwidth-hungry applications priority over less important communications.
