Question 1 of 10
Objective 6.3 Configure basic wireless security on a home router (WPAx)
6.0 Security
A technician sees two SSIDs: `Office-Guest` is open and `Office-Staff` uses WPA2-Personal. A staff laptop containing business data is currently joined to the open guest SSID by mistake. What is the best immediate correction?
The device should use the authorized secured WLAN when business traffic requires WPA protection.

Question 2 of 10
Objective 5.2 Perform a packet capture with Wireshark and save it to a file
5.0 Diagnosing Problems
A technician has a full outage capture and applies a display filter that shows only packets to the failed server. The full original capture must be preserved, but a smaller capture containing only the relevant displayed packets must be sent to an engineer. Which Wireshark action BEST meets both requirements?

Source-backed answer review
The free daily Cisco CCST Networking set includes crawlable question text, answer choices, correct answer labels, objective mapping, and source links. Only the first SEO card includes answer explanations and any extra learning features. Pro-only bank questions stay locked; this section mirrors only the 10 free daily questions already shown on this page.
Question 1 A technician sees two SSIDs: `Office-Guest` is open and `Office-Staff` uses WPA2-Personal. A staff laptop containing business data is currently joined to the open guest SSID by mistake. What is the best immediate correction?
Answer choices
- A. Disable WPA2 on the staff SSID so both networks match
- B. Keep it on the open SSID because the SSID name says Guest
- C. Move the laptop to the secured staff SSID using the approved WPA credential
- D. Use MAC filtering on the laptop instead of joining the protected WLAN
Correct answer
Move the laptop to the secured staff SSID using the approved WPA credential
The device should use the authorized secured WLAN when business traffic requires WPA protection.
Wrong-answer review
- A. Disable WPA2 on the staff SSID so both networks match: Incorrect. Reducing the staff WLAN to open weakens security.
- B. Keep it on the open SSID because the SSID name says Guest: Incorrect. An open guest network provides less link protection and is not made secure by its name.
- D. Use MAC filtering on the laptop instead of joining the protected WLAN: Incorrect. MAC filtering is not a substitute for WPA authentication/encryption.
Extra learning features
Why candidates miss this
The distractor ‘Use MAC filtering on the laptop instead of joining the protected WLAN’ is tempting because MAC filtering is a basic security measure. The decisive clue is the requirement to use the ‘approved WPA credential,’ emphasizing the need for robust authentication, not just network segmentation. Likely wrong answer: Use MAC filtering on the laptop instead of joining the protected WLAN Review focus: Cisco WPA3 Deployment Guide
Question 2 A technician has a full outage capture and applies a display filter that shows only packets to the failed server. The full original capture must be preserved, but a smaller capture containing only the relevant displayed packets must be sent to an engineer. Which Wireshark action BEST meets both requirements?
Answer choices
- A. Save the display filter and assume nonmatching packets are deleted from the original file
- B. Close the original capture, delete it, and recapture only the server traffic
- C. Export the displayed/specified packets to a new capture file while retaining the original capture
- D. Apply a capture filter after the capture has ended to retroactively remove unrelated packets
Correct answer
Export the displayed/specified packets to a new capture file while retaining the original capture
Question 3 Users can ping a web server by IP, but entering its hostname fails. An `nslookup` for the hostname times out. Which protocol/service should the technician investigate FIRST?
Answer choices
- A. NTP
- B. ICMP
- C. DNS
- D. DHCP lease renewal only
Correct answer
DNS
Question 4 A help desk analyst needs a full graphical desktop session to a Windows management workstation, not a Cisco IOS CLI. Which technology BEST fits?
Answer choices
- A. CDP
- B. Console cable to a remote Windows desktop
- C. RDP
- D. SSH only
Correct answer
RDP
Question 5 A technician must patch a standard copper Ethernet workstation NIC to a switch access port. Which connector should be expected on the patch cable?
Answer choices
- A. RJ-11
- B. SC
- C. LC
- D. RJ-45
Correct answer
RJ-45
Question 6 A switch interface is an empty SFP cage. What component must be inserted before attaching the matching media?
Answer choices
- A. An appropriate SFP transceiver
- B. A VLAN database file
- C. A DHCP lease
- D. An RJ-11 splitter
Correct answer
An appropriate SFP transceiver
Question 7 A network design requirement says any single WAN link between four sites may fail without isolating a site, and direct site-to-site paths are preferred. Which topology most directly satisfies the requirement, at the highest circuit cost?
Answer choices
- A. Hub-and-spoke with one link per spoke
- B. Full mesh
- C. Bus
- D. Single-ring with no alternate links
Correct answer
Full mesh
Question 8 A route is written as `2001:db8:1200:3400::/56`. What does `/56` describe?
Answer choices
- A. Exactly 56 hosts may use the subnet
- B. The address contains 56 hexadecimal digits
- C. The first 56 bits are the routing/network prefix represented by that route
- D. The last 56 bits identify the network
Correct answer
The first 56 bits are the routing/network prefix represented by that route
Question 9 An iPhone joins a Wi-Fi network but receives an address from the wrong subnet after a network change. Which evidence is MOST useful to capture from the phone before escalation?
Answer choices
- A. The selected SSID plus the assigned IP address, subnet/prefix, router, and DNS information
- B. The App Store account name only
- C. The device wallpaper
- D. The screen brightness and battery percentage
Correct answer

Question 10 On a Cisco device, an engineer asks a technician to observe whether a port light is solid or blinking while traffic is generated. Why is this observation useful?
Answer choices
