CCNA Network Infrastructure and Connectivity Practice Question

This 200-301 practice question tests your understanding of network infrastructure and connectivity. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

Drag and drop the wireless terms on the left to the correct descriptions on the right.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

SSID: The network name broadcast by an access point to identify the wireless network.

802.11ac (Wi-Fi 5) operates only in the 5 GHz band and introduced support for 160 MHz-wide channels to achieve higher throughput. 802.11ax (Wi-Fi 6) adds OFDMA for more efficient channel use and works in both 2.4 GHz and 5 GHz bands. WPA3-Personal uses SAE (Simultaneous Authentication of Equals) to protect pre-shared key authentication against offline dictionary attacks. A Basic Service Set (BSS) consists of a single AP and its associated clients, identified by the AP's radio MAC address (BSSID). A Wireless LAN Controller (WLC) centralizes management, handling AP configuration, client roaming, and security policies across the wireless network.

Key principle: Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • SSID: The network name broadcast by an access point to identify the wireless network.

    Why this is correct

    SSID (Service Set Identifier) is the human-readable name that identifies a wireless network. Clients use it to select and connect to the desired network.

    Related concept

    CIDR notation defines the prefix length.

  • BSSID: The MAC address of the access point's radio interface, used to uniquely identify a BSS.

    Why it's wrong here

    This is incorrect because BSSID is indeed the MAC address of the AP's radio, but the description is accurate; however, the correct answer for the given description is SSID. This option is a distractor that matches a different term.

  • RSSI: A measurement of the power level of the received radio signal, indicating signal strength.

    Why it's wrong here

    This is incorrect because RSSI (Received Signal Strength Indicator) measures signal strength, but the description in the question is for SSID. This option correctly defines RSSI but does not match the given description.

  • DFS: A mechanism that allows wireless devices to avoid interference with radar systems by dynamically selecting channels.

    Why it's wrong here

    This is incorrect because DFS (Dynamic Frequency Selection) is a channel selection mechanism to avoid radar, not a network name. The description in the question is for SSID.

Option-by-option analysis

Why each answer is right or wrong

Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.

SSID: The network name broadcast by an access point to identify the wireless network.Correct answer

Why this is correct

SSID (Service Set Identifier) is the human-readable name that identifies a wireless network. Clients use it to select and connect to the desired network.

BSSID: The MAC address of the access point's radio interface, used to uniquely identify a BSS.Wrong answer — click to see why

Why this is wrong here

The description provided in the question stem is for SSID, not BSSID. BSSID is the MAC address, not the network name.

Why candidates choose this

Candidates may confuse BSSID with SSID because both are identifiers, but BSSID is a hardware address while SSID is a name.

RSSI: A measurement of the power level of the received radio signal, indicating signal strength.Wrong answer — click to see why

Why this is wrong here

The description in the question is 'network name', not signal strength. RSSI is a metric, not a name.

Why candidates choose this

Candidates may think RSSI is a common term and might match it to a description about signal, but the description here is about naming.

DFS: A mechanism that allows wireless devices to avoid interference with radar systems by dynamically selecting channels.Wrong answer — click to see why

Why this is wrong here

DFS is about channel selection and radar avoidance, not about identifying a network by name.

Why candidates choose this

Candidates might confuse DFS with SSID because both are wireless terms, but their functions are completely different.

Common exam traps

Common exam trap: usable hosts are not the same as total addresses

Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.

Detailed technical explanation

How to think about this question

Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.

KKey Concepts to Remember

  • CIDR notation defines the prefix length.
  • Block size helps identify subnet boundaries.
  • Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
  • The required host count determines the smallest suitable subnet.

TExam Day Tips

  • Write the block size before choosing the subnet.
  • Check whether the question asks for hosts, subnets or a specific address range.
  • Do not confuse /24, /25, /26 and /27 host counts.

Key takeaway

Count usable hosts — not total addresses — and remember that the network and broadcast addresses are not available to hosts in standard IPv4 subnets.

Real-world example

How this comes up in practice

A network engineer segments a warehouse floor into three subnets: 20 scanners, 5 printers, and 2 management hosts. Picking the wrong mask wastes addresses or leaves too few usable hosts. Exam questions test whether you can apply CIDR notation, calculate block size, and identify the correct usable-host range for a given prefix.

What to study next

Got this wrong? Here's your next step.

Review block sizes, usable host formulas (2^n − 2), and how to find network and broadcast addresses for /24 through /30. Then practise related 200-301 subnetting questions on CIDR, address ranges, and subnet selection.
