Your organization is migrating its core network from traditional L2/L3 switches to SDN-enabled switches managed by a centralized controller. During the migration, some segments of the network are operating on SDN switches while others are still using legacy infrastructure. Shortly after deployment, your team notices: Certain flows are not being forwarded as expected. Packet delivery across hybrid segments is inconsistent. Flow entries appear missing or outdated on several SDN switches. As the lead network engineer, you’re asked to diagnose the issue.Which of the following is the most likely cause, and why?

The figure below shows a typical bacterial growth curve with the y-axis indicating the log of the number of bacteria and the x-axis indicating time in culture.  Refer to the graph and choose the growth phase that best matches the following description.         Cells are metabolically active and adapting to the new environmental conditions,   but not yet dividing.

Your lab partner has mixed a dead tryptophan + strain of Bacillus subtilis with a live tryptophan– strain and observes that her  Bacillus subtilis culture is now tryptophan +. The most likely explanation for this is __________. Please note that tryptophan + strain can synthesize tryptophan on its own, and therefore does not require it to be supplemented in the growth medium.  This contrasts with a tryptophan–  strain, which cannot synthesize tryptophan due to a mutation and thus needs tryptophan added to its medium to grow.
