This option can be used to create virtual private network (VPN) connections that can be distributed to users' computers so that VPN clients do not need to be configured on each client station is a VPN connection profile.
Users can send and receive data over shared or public networks as if their computer equipment were physically connected to a private network using a virtual private network (VPN), which extends the private network over the public network.
Increased functionality, security, and private network administration are all benefits of a VPN. It is often used by remote workers and allows access to resources that are not available on the public network. Although not an essential part of a VPN connection, encryption is often used.
By using dedicated circuits or tunneling protocols over existing networks, a VPN can be created by creating a virtual point-to-point connection.

Answer:
The answer is The Cache Sets (S) = 32, Tag bits (t)=24, Set index bits(s) = 5 and Block offset bits (b) = 3
Explanation:
Solution
Given Data:
Physical address = 32 bit (memory address)
Cache size = 1024 bytes
Block size = 8 bytes
Now
It is a 4 way set associative mapping, so the set size becomes 4 blocks.
Thus
Number of blocks = cache size/block size
=1024/8
=128
The number of blocks = 128
=2^7
The number of sets = No of blocks/set size
=128/4
= 32
Hence the number of sets = 32
←Block ←number→
Tag → Set number→Block offset
←32 bit→
Now, =
The block offset = Log₂ (block size)
=Log₂⁸ = Log₂^2^3 =3
Then
Set number pc nothing but set index number
Set number = Log₂ (sets) = log₂³² =5
The remaining bits are tag bits.
Thus
Tag bits = Memory -Address Bits- (Block offset bits + set number bits)
= 32 - (3+5)
=32-8
=24
So,
Tag bits = 24
Therefore
The Cache Sets = 32
Tag bits =24
Set index bits = 5
Block offset bits = 3
Note: ←32 bits→
Tag 24 → Set index 5→Block offset 3
