cat5e cant go more than 1GBps

A. 10GBASE-T: Description: 10GBASE-T is designed for 10 Gigabit Ethernet over twisted pair copper cabling. Maximum Data Rate: 10 Gbps. Common Use: Suitable for high-speed Ethernet connections. C. Cat 5e: Description: Category 5e (Cat 5e) is a type of twisted pair cable designed for high signal integrity. Maximum Data Rate: Up to 1 Gbps. Common Use: Although not designed for 2.5-Gbps and 5-Gbps speeds, Cat 5e may support these speeds over shorter distances and is often used in practice for such connections. Therefore, the suitable cable types for connecting an access point to the WLC when 2.5-Gbps and 5-Gbps speeds are required are likely to be a combination of 10GBASE-T (option A) and Cat 5e (option C).

Correct answers are A & C

A and C are correct

A & C are correct

A & C are correct

Cat5e: Gigabit Ethernet up to 100 meters 10 Gigabit Ethernet up to 45 meters

C. Cat 5e - Cat 5e cabling can support up to 1 Gbps (Gigabit Ethernet) over distances of up to 100 meters. However, with specific hardware and shorter distances, it can also support 2.5 Gbps speeds under the NBASE-T standard.

No correct answer is possible with presented options. 2.5 Gigabit requires Cat 5e cable, 5 Gigabit requires Cat 6 cable. Correct answer could be: Cat 5e, Cat 6 10GBASE-T and 1000BASE-LX/LH are not cable types.

A more viable option is to upgrade your Cat5e cable without ever touching a wall. This is the approach that Cisco and the NBASE-T Alliance have taken to give us an immediate and cost effective solution. Thanks to their work, there is now a solution where you can get 2.5 and even 5 Gbps across existing Cat5e cable. https://www.mercadoit.com/blog/noticias-it/como-cisco-catalyst-multigigabit-puede-aumentar-las-velocidades-de-red/

cat 5e and base-T

Why not AB??

With the inclusion of the IEEE 802.3bz standard you can even get more performance with your existing Cat5e cables. Under the standard of IEEE 802.3bz you can achieve up to 2.5GBase-T and 5GBase-T up to 328 Feet (100 meters). It's able to achieve this by having the layer of transmissions be based on 10GBase-T but perform at a lower signal rate. When lowering the signal rate it reduces the cabling requirements giving you the ability to perform this on Cat5e. While this is certainly obtainable it's not a guarantee. For Cat5e we can look to the baseline performance of 1Gb up to 328 Feet as the standard performance you can achieve and 2.5 or 5GBase-T being the performance under ideal environments including capable hardware. https://infinity-cable-products.com/blogs/performance/what-is-the-cat5e-max-speed So, Cat 5e could be the theoretically correct answer.

CAT5e and CAT6 can handle speeds of up to 1000 Mbps, or a Gigabit per second.

The use of proper cable types will directly affect the performance of the Catalyst 9136I (A cisco AP). Since this AP has 5-Gbps ports, the recommendation is to use either CAT6 or CAT 6a cable, which support speeds of up to 10 Gbps. CAT 5e cables can still be used; however, there may be an effect on the AP’s performance. Since there is no option for Cat6 or Cat6e so answer should be 10G and Cat5e.
