sequential consistency implies quiescent consistency

• True

• False

If an Execution E is liniarizable and quiescent consistent, then it must also be sequential consistency

• True

• False

Are there guarantees a Lamport clock can achieve a vector clock cannot

• No

• Yes

Which consistency models are composable:

• Linearizability

• Sequentially consistent

• Quiescent consistency

if: a->b, a->d and b->c then:

• a->c

• b->d

• c->a

• d->b

Decreasing epsilon will:

• Increase the runtime

• Decrease the runtime

• Leave the runtime unchanged

Approximate Agreement can be achieved with n<3f byzantine nodes in

• The synchronous model only

• The asynchronous model only

• The synchronous and asynchronous model

• In neither model
