A workstation can reach an internal site's IP address but cannot open the site by hostname. What is the most appropriate next test?

  1. A

    Replace the workstation's network cable immediately.

  2. B

    Change the route to the destination before checking other evidence.

  3. C

    Test name resolution and investigate the DNS response or configuration.

  1. A

    The time the symptoms occurred

  2. B

    The affected devices and network location

  3. C

    A series of setting changes made before recording observations

  4. D

Two laptops on the same access point are slow when opening one site, while wired desktops reach it normally. Which action best helps isolate the problem?

  1. A

    Change the site's routing configuration immediately.

  2. B

    Compare the affected wireless connection and path with a known-good device or location.

  3. C

    Assume the inventory server is unavailable because wireless users are slow.

  4. D

    Replace all network cables in the building.

    The symptom and its scope

  2. B

    Evidence gathered and tests with their results

  3. C

    The identified cause

  4. D

    Changes made and verification results

After identifying the affected endpoint, which part of its connection should you check first when tracing the communication path outward?

10
True or false

If a temporary workaround restores access, that alone proves the root cause has been removed.

One workstation cannot access a network resource, but a nearby workstation can. Which next step best uses this evidence to narrow the cause?

  1. A

    Replace the site's network equipment because the failure must be site-wide.

  2. B

    Change several settings on the affected device and see whether the symptom disappears.

  3. C

    Assume the destination service is down because one device cannot connect.

  4. D

    Compare the affected device's cable or configuration with a nearby known-good device.

Which details should a clear network problem statement capture?

  1. A

    The network has a problem that should be investigated soon.

  2. B

    Two laptops on the east-floor access point take 8–12 seconds to open the inventory site; wired desktops reach it normally.

  3. C

    Users may be having trouble with some applications.

  4. D

    The network should be checked for possible configuration issues.

When investigating a suspected network performance problem, what should you compare with the affected path’s normal baseline?

  1. A

    The number of devices that have ever connected to the network.

  2. B

    The age of the affected users’ computers and their preferred applications.

  3. C

    Latency, throughput, error counts, or utilization compared with the path’s normal baseline.

  4. D

    The current configuration compared only with a hypothetical ideal configuration.

After applying a network fix, which action best verifies that it worked?

  1. A

    Repeat the original test under the conditions that produced the problem and confirm the affected service works.

  2. B

    Treat one successful test as sufficient proof, even if the symptom was intermittent.

  3. C

    Apply another speculative change before repeating any tests.

  4. D

    Confirm only that the change was made, without checking the affected service.

A user reports intermittent slowness on one network path. Which approach provides the strongest evidence for evaluating a performance-related cause?

  1. A

    Compare latency, throughput, error counts, or utilization with the affected path’s normal baseline.

  2. B

    Change several performance settings and judge whether the connection feels faster.

  3. C

    Compare the affected path only with a different network’s current performance.

  4. D

    Assume that high latency is the cause without collecting measurements.
