Describe the issue of duplicate SSIDs and why this may cause a wireless device to intermittently disconnect from the AP.
What will be an ideal response?
If the same SSID is used on another AP, then both APs are considered to be part of the same network and must share the same security settings. However, in instances where a default SSID has not been changed, it is possible that two separate devices not intended to be part of the same WLAN (such as two devices in the same apartment building) are broadcasting the same SSID. The wireless device may then choose the remote AP of another wireless network instead of the local AP. Because that remote device will not be configured for the same authentication method and keys of the main wireless network, the wireless device will not be able to connect to it.

How is bus snooping implemented to ensure cache coherence?
a) The system maintains a centralized directory that records the items in each processor's cache. On a cache write, the writing processor "snoops" this list to determine whether the item is in other processors' caches, and if so, tells these other processors to remove the item. b) The system only allows one processor at a time to cache each data item; when a processor tries to cache a data item, it "snoops" other processors’ caches over the bus to determine whether it is allowed to cache the data. c) Each processor "snoops" the processor-memory bus to determine whether another processor has sent a message about an update to a data item stored in its cache. d) Each processor “snoops” the bus to determine whether a requested write from another processor is for a data item in the processor’s cache. If the data resides in the processor’s cache, the processor removes the data item from its cache.
