1.Masalah jaringan karena kegagalan piranti jaringan

Skala gangguan akibat dari kegagalan piranti jaringan juga bisa bervariasi, dari hanya sebuah komputer karena kegagalan NIC – lan card; beberapa komputer karena kegagalan switch; atau bahkan berskala luas karena kegagalan pada switch central yang menghubungkan jaringan server. Untuk kegagalan lan card di salah satu komputer bisa diganti dengan network card cadangan anda.
Terus bagaimana kalau kegagalan jaringan itu akibat kerusakan pada switch? Design anda mengenai redundansi jaringan akan sangat membantu dalam menyelamatkan kegagalan jaringan anda. Kebutuhan load balancing dan redundansi haruslah dikaji untuk setiap kebutuhan berdasarkan penggunaan link redundansi; piranti router; switch dan multi-homed host yang bersifat kritis. Tujuan dari system redundansi ini dimaksudkan untuk menjamin ketersediaan layanan dimana tidak ada satupun titik rawan kegagalan.

2.Hal yang perlu di upgrade yaitu Masalah jaringan karena kegagalan kabel jaringan
Yang ini merupakan masalah jaringan yang umum kita temui akibat putusnya kabel jaringan yang bisa mempengaruhi kinerja sebuah komputer dalam jaringan karena putusnya kabel patch anda karena digigit tikus; masalah jaringan yang berdampak pada satu blok gedung karena putusnya kabel antar switch (uplink cable); atau bahkan berdampak pada sebagian besar komputer dalam jaringan lan anda karena kegagalan backbone cable.
