Which of the following source control features allows an administrator to test a new configuration without changing the primary configuration?

Branching creates an isolated copy of the configuration so you can test changes without affecting the primary configuration.
A network engineer needs to change, update, and control APs remotely, with real-time visibility over HTTPS.Which of the following will best allow these actions?
Answer(s): D
An API gateway exposes a RESTful (or similar) interface over HTTPS, allowing clients to programmatically push configuration changes, retrieve status, and control access points in real time.While a web interface also uses HTTPS, it's typically user-interactive (browser-based) rather than scriptable or easily automatable. A command-line interface might be available via SSH, but that's not over HTTPS and is less suited to real-time web integration. SNMP is for monitoring and limited configuration but is not natively tunneled over HTTPS and doesn't provide the same modern programmability.
Which of the following is a location where a plenum cable is recommended?
"Plenum" refers to the air-handling spaces in buildings - typically the space above a dropped ceiling or below a raised floor used for air circulation. In these areas, regulations require cables with low-smoke, low-toxicity jacketing, to reduce toxic fumes if there's a fire. Frequently traveled areas may need more rugged or protected cabling but not specifically plenum-rated. Outdoor environments demand weatherproof or UV-resistant cables.Inside conduits often allow regular PVC-jacketed cable because the conduit provides fire containment.
A customer calls the help desk to report issues connecting to the internet. The customer can reach a local database server. A technician goes to the site and examines the configuration:Which of the following is causing the user's issue?

A company recently implemented a videoconferencing system that utilizes large amounts of bandwidth. Users start reporting slow internet speeds and an overall decrease in network performance.Which of the following are most likely the causes of the network performance issues? (Choose two.)
Answer(s): E,F
Incorrect QoS settings Without prioritization, videoconferencing traffic can monopolize bandwidth and degrade other services.Network congestion The high bandwidth requirements of video calls can saturate links, causing overall slowdowns.
A technician needs to identify a computer on the network that is reportedly downloading unauthorized content.Which of the following should the technician use?
