A newly connected switch port has no link indicator. What is the best initial troubleshooting action?
- A
Check power, cable seating and path, termination, patch cable, and port status.
- B
Change the client’s DNS server and test again.
- C
Change the VLAN gateway address.
- D
Disable access controls on the router.
A client can ping its own VLAN gateway but cannot reach a host on another subnet. Which set of checks best fits this symptom?
- A
Replace the access point because the client can reach its gateway.
- B
Change the cable tester’s wire-map setting.
- C
Check routing, subnet mask, return route, and access-control rules.
- D
Change the SSID without checking the network configuration.
During final acceptance testing, which checks help establish that the network behaves according to its intended policy? Select all that apply.
- A
Verify that permitted inter-VLAN traffic works and blocked traffic remains blocked.
- B
Assume access rules work if all client devices receive IP addresses.
- C
Test DNS resolution and any required Internet access.
- D
Confirm that the management interface is reachable only from authorized locations.
A wireless client associates with its SSID but has no network access. Which checks are relevant to this symptom? Select all that apply.
- A
Check the AP uplink and VLAN tagging.
- B
Check DHCP and gateway configuration.
- C
Check client isolation settings.
- D
Check authentication settings.
Creating separate VLANs by itself guarantees that guest clients cannot access staff or management networks.
- A
True
- B
False
Near electrical hazards, using a nonconductive ladder is a recommended safety practice.
- A
True
- B
False
What is the design called when one router link carries tagged traffic for multiple VLANs and the router uses a subinterface for each VLAN?
What type of tester should be used to certify that a cable installation meets applicable performance standards?
A VLAN separates Layer 2 domains. Communication between VLANs requires a device.
If a DHCP server is outside a client VLAN, configure and verify DHCP on that VLAN’s gateway.
After isolating and correcting a network fault, what should the troubleshooting record include, and how should changes be tested to make the result reliable?
Before connecting network equipment, what can a basic cable tester verify about a link?
- A
Check wire map and continuity before connecting equipment.
- B
Confirm the client has received the correct DNS server.
- C
Certify the cable category and performance from a basic wire-map pass.
- D
Confirm that inter-VLAN access rules are working.
A basic cable tester reports a wire-map pass on a newly installed Ethernet link. What can you conclude from that result?
- A
It certifies that the cable meets its category’s performance requirements.
- B
It checks wire map and continuity, but does not certify cable category or performance.
- C
It confirms that every switch port on the link is configured correctly.
- D
It verifies that the cable can carry tagged traffic for every VLAN.
In the example addressing plan, which VLAN ID is designated for network management? Enter the VLAN ID.
A wired staff endpoint must connect to VLAN 10 through a managed switch. How should its switch port normally be configured?
- A
Configure it as an access port in the endpoint’s intended VLAN.
- B
Configure it as a trunk carrying every VLAN on the switch.
- C
Disable VLAN membership so the endpoint can select its own VLAN.
- D
Configure it as a router subinterface.
True or false: Creating separate staff and guest VLANs, by itself, guarantees that guest clients cannot reach staff devices.
- A
True
- B
False
An access point maps multiple SSIDs to separate VLANs. What switch-port mode does its uplink generally need? Enter the switch-port mode.
A DHCP server is located outside a client VLAN, and clients in that VLAN need addresses from it. What should be configured on the VLAN gateway?
- A
Configure the client switch port to obtain DNS settings from the AP.
- B
Add the server’s VLAN to the client port as a second access VLAN.
- C
Configure DHCP relay on the client VLAN’s gateway.
- D
Replace the client’s default gateway with the DHCP server’s address.
In a router-on-a-stick design, which configuration allows the router to provide gateways for several VLANs over one physical link?
- A
Use an untagged router link and configure all gateways on one router interface.
- B
Assign every router subinterface the same VLAN tag.
- C
Configure VLAN tags only on the switch and leave router subinterfaces untagged.
- D
Carry tagged VLAN traffic on the router link and match each subinterface tag to its VLAN.
