An administrator has successfully implemented SSL on srv4.comptia.com using wildcard certificate *.comptia.com, and now wishes to implement SSL on srv5.comptia.com. Which of the following files should be copied from srv4 to accomplish this?

  1. certificate, private key, and intermediate certificate chain

  2. certificate, intermediate certificate chain, and root certificate

  3. certificate, root certificate, and certificate signing request

  4. certificate, public key, and certificate signing request

Answer: A Explanation:

a wildcard certificate is a public key certificate which can be used with multiple subdomains of a domain. In public-key cryptography, the receiver has a private key known only to them; a public key corresponds to it, which they make known to others. The public key can be sent to all other parties; the private key is never divulged. A symmetric algorithm requires that receivers of the message use the same private key. Thus you should copy the certificate, the private key and the intermediate certificate chain from srv4 to srv5.

Question No: 487 – (Topic 2)

Which of the following results in datacenters with failed humidity controls? (Select TWO).

  1. Excessive EMI

Answer: B,D Explanation:

Humidity control prevents the buildup of static electricity in the environment. If the humidity drops much below 50 percent, electronic components are extremely vulnerable to damage from electrostatic shock. Most environmental systems also regulate humidity; however, a malfunctioning system can cause the humidity to be almost entirely extracted from a room. Make sure that environmental systems are regularly serviced. Electrostatic damage can occur when humidity levels get too low. Condensation is a direct result from failed humidity levels.
