You are running Cisco IOS IPS software on your edge router. A new threat has become an issue.
The Cisco IOS IPS software has a signature that can address the new threat, but you previously
retired the signature. You decide to unretire that signature to regain the desired protection level.
How should you act on your decision?
A.
Retired signatures are not present in the routers memory. You will need to download a new
signature package to regain the retired signature.
B.
You should re-enable the signature and start inspecting traffic for signs of the new threat.
C.
Unretiring a signature will cause the router to recompile the signature database, which can
temporarily affect performance.
D.
You cannot unretire a signature. To avoid a disruption in traffic flow, it’s best to create a custom
signature until you can download a new signature package and reload the router.
Explanation:
Some signatures can be retired. This signature is not present in the routers memory. Unretiring a
retired signature requires that the router recompile the signature database.
This can temporarily affect performance and take a long time with a large signature database.
