Question 181.
Which factor is most important when selecting an AP switch port?
- DNS response time
- Required link speed
- SSID character limit
- User login duration
Correct Answer: 2
Explanation:
The switch port connecting an access point should provide sufficient link speed for the AP’s expected traffic and capabilities. Modern access points can generate substantial aggregate traffic, particularly when supporting many high-throughput clients or multiple radios. A slower Ethernet connection can become a bottleneck even when the wireless interface has greater theoretical capacity. Engineers should therefore match AP capabilities with appropriate switch interfaces and verify uplink capacity as well. Port speed is only one component of wired planning, but it directly influences how much traffic can move between the AP and the rest of the network.
Question 182.
What is the primary purpose of grounding outdoor wireless equipment?
- Improve channel reuse
- Reduce SSID visibility
- Provide electrical protection
- Increase client density
Correct Answer: 3
Explanation:
Grounding outdoor wireless equipment helps provide a controlled path for unwanted electrical energy and supports protection against electrical hazards. Outdoor APs, antennas, masts, and associated infrastructure can be exposed to static buildup, surges, and lightning-related events. Proper grounding should follow applicable electrical and installation standards and should be coordinated with the building’s grounding system. Grounding does not improve RF channel reuse or directly increase client capacity. It is primarily a physical infrastructure and safety consideration that should be incorporated into outdoor WLAN deployment planning.
Question 183.
What does an outdoor enclosure rating help indicate?
- Environmental protection
- Authentication strength
- Channel availability
- Client modulation
Correct Answer: 4
Explanation:
An enclosure rating indicates the degree of protection equipment receives against environmental factors such as dust or water ingress, depending on the applicable rating system. Outdoor WLAN equipment may face rain, humidity, dust, temperature changes, and other conditions that are uncommon in controlled indoor spaces. Selecting equipment or enclosures appropriate for the deployment environment helps preserve reliability and service life. The rating does not describe wireless authentication or modulation behavior. Engineers should evaluate the environmental conditions at the installation site before selecting outdoor APs, antennas, enclosures, and related mounting hardware.
Question 184.
Why is a lightning arrestor used in an outdoor antenna system?
- Reduce VLAN overhead
- Protect connected equipment
- Increase antenna beamwidth
- Improve DHCP performance
Correct Answer: 2
Explanation:
A lightning arrestor helps protect connected wireless equipment by providing a controlled path for surge energy associated with lightning or other electrical events. Outdoor antenna systems can provide conductive paths into buildings, making surge protection an important component of the physical design. The arrestor must be installed and grounded according to applicable requirements and manufacturer guidance. It does not improve RF throughput or network-layer performance. A complete outdoor WLAN design should consider grounding, bonding, surge protection, cable routing, weather exposure, and physical mounting as related infrastructure concerns.
Question 185.
Which characteristic is desirable for an outdoor RF cable?
- High insertion loss
- Excessive flexibility
- Low attenuation
- Uncontrolled impedance
Correct Answer: 3
Explanation:
Low attenuation is desirable in an outdoor RF cable because it minimizes the amount of signal power lost between the radio and antenna. Cable losses can become increasingly important as cable runs become longer or operating frequencies increase. Designers should select cable types with characteristics appropriate to the frequency range, installation environment, and required distance. The cable’s impedance must also match the connected RF components. Excessive loss can reduce the power delivered to an antenna and weaken received signals. Therefore, cable selection is an important part of maintaining the intended RF path performance.
Question 186.
Which physical factor should be considered when mounting a directional antenna?
- Azimuth alignment
- DHCP scope
- VLAN numbering
- DNS caching
Correct Answer: 1
Explanation:
Azimuth alignment determines the horizontal direction in which a directional antenna is pointed. Accurate alignment is essential when the antenna is intended to focus coverage toward a particular service area or establish a point-to-point wireless path. Even a relatively small horizontal orientation error can move the main radiation pattern away from the intended target. Engineers should document the planned azimuth and verify the installed orientation during deployment. Vertical elevation, downtilt, antenna polarization, and mounting stability may also need to be checked to ensure the physical installation matches the RF design.
Question 187.
What can excessive antenna cable length cause?
- Lower RF power
- Larger IP pools
- Faster authentication
- Wider channels
Correct Answer: 1
Explanation:
Longer antenna cables generally introduce greater RF attenuation, reducing the signal power that reaches the antenna or receiver. The magnitude of the loss depends on cable construction, operating frequency, and total length. This can affect the overall RF path and may reduce the effective performance of the wireless system if the loss was not included in the design calculations. Using an appropriate low-loss cable and keeping the RF path reasonably short can help preserve signal power. Cable selection should therefore be completed as part of the overall antenna and radio design.
Question 188.
What does antenna diversity primarily exploit?
- Different IP routes
- Multiple propagation paths
- Separate authentication realms
- Multiple DHCP servers
Correct Answer: 2
Explanation:
Antenna diversity uses multiple antenna elements or paths to improve the likelihood that a useful signal will be available despite changing propagation conditions. Because wireless signals can experience fading and variations across different spatial positions, one antenna path may perform better than another at a particular moment. A radio can select or combine suitable paths according to its implementation. Diversity is therefore an RF technique rather than a network-layer redundancy mechanism. Proper antenna placement and radio support are still required for the intended diversity behavior to provide meaningful benefits.
Question 189.
Which feature allows a radio to transmit using multiple spatial paths simultaneously?
- VLAN trunking
- STBC
- Spatial streams
- Port aggregation
Correct Answer: 3
Explanation:
Spatial streams represent independent streams of data transmitted through a MIMO-capable wireless system. Using multiple spatial streams can increase the amount of information transferred during a transmission when the client, AP, and RF environment support the required conditions. The number of usable streams depends on the capabilities of both communicating devices and the quality of the propagation environment. Spatial streams should not be confused with Ethernet link aggregation or VLAN trunking. When estimating WLAN performance, engineers should account for actual client capabilities rather than assuming every device can use the maximum number of available streams.
Question 190.
What does STBC primarily provide?
- Improved resilience
- Additional VLANs
- Faster DNS queries
- Larger address pools
Correct Answer: 1
Explanation:
Space-Time Block Coding (STBC) uses multiple spatial and temporal transmission patterns to improve the robustness of wireless communication under suitable conditions. Rather than being primarily intended to increase peak throughput, STBC can provide additional resilience against challenging propagation conditions. Its effectiveness depends on the capabilities of the communicating devices and the radio implementation. Designers should distinguish robustness-oriented mechanisms from technologies intended mainly to increase capacity. STBC can be particularly relevant when maintaining reliable communication is more important than maximizing the highest possible data rate.
Question 191.
Which Wi-Fi 6 capability improves efficiency for small client transmissions?
- OFDMA
- WEP
- NAT
- ARP
Correct Answer: 1
Explanation:
OFDMA allows an 802.11ax access point to divide a channel into resource units and coordinate transmissions involving multiple clients. This can improve efficiency when clients have relatively small or varied amounts of data because the entire channel does not necessarily need to be allocated to one client for every transmission opportunity. The feature is particularly useful in environments containing many active devices with diverse traffic patterns. Actual benefits depend on compatible clients, traffic characteristics, and infrastructure configuration. OFDMA is therefore an important capacity-efficiency mechanism in modern high-density WLAN designs.
Question 192.
What does spatial reuse seek to improve in dense WLANs?
- Spectrum efficiency
- Cable shielding
- Authentication speed
- Power supply voltage
Correct Answer: 1
Explanation:
Spatial reuse seeks to allow wireless systems to make more efficient use of the available spectrum when multiple WLAN cells operate in the same general area. Techniques associated with modern Wi-Fi can help devices distinguish transmissions and determine when channel access may be possible without unnecessarily deferring to every detected signal. Proper spatial reuse depends on factors such as transmit power, cell boundaries, channel configuration, and client behavior. It does not eliminate interference entirely. Engineers should evaluate spatial reuse as part of a broader dense-deployment strategy rather than treating it as a substitute for sound RF planning.
Question 193.
What does BSSID identify within a WLAN?
- A specific BSS
- A routing protocol
- A cable standard
- A controller license
Correct Answer: 1
Explanation:
A Basic Service Set Identifier (BSSID) identifies a specific Basic Service Set and is commonly represented by a MAC address associated with the wireless interface providing that BSS. Multiple BSSIDs can exist within the same physical infrastructure, and an SSID can be presented through multiple BSS instances. Understanding the distinction between SSID and BSSID is useful when analyzing WLAN operation, roaming, captures, and troubleshooting. BSSID identification is therefore more specific than simply naming the wireless network through its SSID.
Question 194.
Which WLAN identifier is normally visible to users as the network name?
- BSSID
- SSID
- PMK
- RADIUS realm
Correct Answer: 2
Explanation:
The Service Set Identifier (SSID) is the logical name commonly displayed to users when they select a wireless network. It identifies the WLAN service from a user-facing perspective, while the BSSID identifies a particular Basic Service Set instance. A single SSID can be provided by multiple access points to support a larger WLAN and roaming environment. SSID design should consider usability, security policy, segmentation requirements, and operational clarity. Although hiding an SSID can alter discovery behavior, it should not be considered a substitute for proper WLAN security controls.
Question 195.
What is a primary purpose of a guest WLAN?
- Isolate visitor access
- Increase antenna gain
- Expand RF channels
- Replace wired uplinks
Correct Answer: 1
Explanation:
A guest WLAN is commonly designed to provide network access to visitors while limiting their ability to reach protected internal resources. Isolation can be achieved through VLAN segmentation, firewall policies, access controls, captive portals, or other security mechanisms depending on the architecture. Simply creating a separate SSID does not automatically guarantee isolation; the underlying network policy must enforce the intended boundaries. Guest WLAN requirements should therefore be incorporated into both the wireless design and the wired security architecture so that visitor traffic follows an appropriately restricted path.
Question 196.
What does 802.1X commonly provide for enterprise WLAN access?
- Port-based authentication
- Antenna alignment
- Channel measurement
- Cable weatherproofing
Correct Answer: 1
Explanation:
IEEE 802.1X provides a framework for port-based network access control and is widely used with enterprise WLAN authentication. In a wireless deployment, it can work with an authentication server and an appropriate EAP method to validate users or devices before granting network access. This approach is different from RF functions such as channel planning or antenna alignment. Enterprise WLAN designs should consider authentication architecture, credential management, certificate requirements where applicable, and the relationship between the wireless infrastructure and authentication services. Successful implementation also requires compatible client configurations.
Question 197.
Which server commonly processes enterprise WLAN authentication requests?
- RADIUS server
- Web proxy
- DNS server
- NTP server
Correct Answer: 1
Explanation:
A RADIUS server commonly handles authentication and authorization requests for enterprise WLAN environments using mechanisms such as 802.1X. The access point or wireless controller can act as an authenticator, forwarding relevant authentication exchanges toward the RADIUS infrastructure. Depending on the deployment, RADIUS may also provide authorization attributes that influence network access. DNS and NTP serve different infrastructure functions and do not replace the role of a RADIUS authentication service. WLAN designers should consider server availability, network reachability, shared configuration, certificate dependencies, and failure behavior when planning enterprise authentication.
Question 198.
Why should guest traffic be placed in a separate security segment?
- Limit internal exposure
- Increase RF power
- Improve antenna gain
- Expand channel width
Correct Answer: 1
Explanation:
Separating guest traffic from internal network resources helps reduce the risk that visitor devices can directly access protected systems. A dedicated VLAN or comparable segmentation mechanism can provide the foundation for applying firewall rules and access policies specific to guest users. The exact architecture varies by organization, but the objective is to establish clear security boundaries. Wireless segmentation should be validated from the client perspective to ensure that unintended internal routes are not available. Merely assigning a different SSID is insufficient unless the wired and security infrastructure enforces the desired isolation.
Question 199.
What is a key function of a WIDS?
- Detect suspicious wireless activity
- Increase Ethernet speed
- Modify antenna gain
- Allocate IP addresses
Correct Answer: 1
Explanation:
A Wireless Intrusion Detection System (WIDS) monitors wireless activity for events or behaviors that may indicate security concerns. Depending on the platform, it can help identify rogue access points, unauthorized devices, suspicious associations, policy violations, or other wireless anomalies. Detection is different from containment or prevention, which may involve additional mechanisms and operational considerations. A WIDS should be integrated into the broader WLAN security and monitoring strategy. Engineers should also establish procedures for investigating alerts so that legitimate neighboring networks are not automatically treated as confirmed security incidents.
Question 200.
What should a rogue AP investigation establish first?
- Device identity and location
- New channel width
- Higher transmit power
- Different SSID typography
Correct Answer: 1
Explanation:
A rogue access-point investigation should first establish what the device is and where it is physically located. Wireless monitoring can identify suspicious RF activity, but determining whether a device is genuinely unauthorized often requires correlation with network records and physical inspection. Once the device is identified, security personnel can determine the appropriate response according to organizational policy. Immediate assumptions can lead to legitimate infrastructure being incorrectly classified. A structured investigation therefore combines RF observations, device information, wired-network evidence, and documented security procedures before corrective action is taken.
