Certified ExpertA.That does appear to be one, and it won't be necessary to trim the leaves unless they are fully dead. This article will help you to care for these palms: https://www.gardeningknowhow.com/ornamental/trees/bismarck-palm/growing-bismarck-palms.htm

Certified ExpertA.Oh boy... That was a fungal infection caused by the Palmetto Weevil. It was likely attacked by the insect and taken within a very short period.

One of our established Bismarck Palm's top growth looks like it's dying- it's limp with droopy leaves & so are the nutbearing inflorescence.

October 21, 2019A.Bismarck palm leaves may show nutrient deficiencies or the effect of weevil infestation. I have provided a link that discusses potential nutritional problems, pests, and diseases of this palm. Getting a soil test may help you nail down the problem. Your state Extension Service offers low cost, comprehensive testing. http://edis.ifas.ufl.edu/pdffiles/ST/ST10100.pdf

Certified ExpertA.That is a severe case of scale, and will be VERY difficult to get rid of. Most of the treatment will be, manually, scraping all of it off to the best of your ability. Then you can treat with organic or chemical means.

Certified ExpertA.They are normally silvery green, but yours doesn't look that color either. They need the nutrients potassium, magnesium and boron, so a soil test may be in order. These plants can grow up to 60 feet if planted.

34224Q.11 Year-old Bismark Palm Developing Speckles On Fronds And New Growth Is Not Opening
I noticed something wasn't right when four new brown shoots shot up and never opened into new fronds. Instead, the tree is accomodating the new growth by splitting in half at the top. Now there is a noticeable gap at the top.

Certified ExpertA.Unfortunately, your photo did not come through. I am unable to see the damage.
It does sound like an infection has set in. Bacterial spot is common in soils that remain wet, or are too heavy to dry quickly.
I would recommend a fungicide, and to ensure that the soil has a chance to dry out down to about 2 or 3 inches between watering when possible to prevent future infections.
Here are some articles that will help:
