• Question 191:

  The CASB report indicates several unsanctioned SaaS applications are being used in an organization. Which of the following is the MOST likely cause?

  A. VPN bypass

  B. Shadow IT

  C. Web proxy bypass

  D. CAB approval

  Correct Answer: B

• Question 192:

  An administrator is securing a private cloud environment and wants to ensure only approved systems can connect to switches. Which of the following would be MOST useful to accomplish this task?

  A. VLAN

  B. NIPS

  C. WAF

  D. NAC

  Correct Answer: D

  NAC (Network Access Control) is what the administrator should implement to ensure only approved systems can connect to switches in a private cloud environment. NAC is a security technique that controls and restricts access to network resources based on predefined policies or rules. NAC can verify and authenticate users or devices before granting them access to switches or other network devices. NAC can also enforce compliance and security standards on users or devices before allowing them to connect to switches.

• Question 193:

  An organization is currently deploying a private cloud model. All devices should receive the time from the local environment with the least administrative effort. Which of the following ports needs to be opened to fulfill this requirement?

  A. 53

  B. 67

  C. 123

  D. 161

  Correct Answer: C

  Port 123 is what needs to be opened to ensure all devices receive the time from the local environment with the least administrative effort in a private cloud model. Port 123 is the port used by NTP (Network Time Protocol), which is a protocol that synchronizes the clocks of network devices and systems. NTP can help to ensure accurate and consistent time across different devices and systems in a cloud environment, which can facilitate coordination, communication, logging, auditing, etc.

• Question 198:

  A cloud administrator is managing two private cloud environments. In cloud A, the disaster recovery solution has an SLA for RPO of five minutes and RTO of one hour. In cloud B, the disaster recovery solution has an SLA for RPO of one hour and RTO of 24 hours. A new customer's application requires that, in case of a disaster, no more than 15 minutes of data can be lost, and it should be fully recovered within one day.

  Which of the following would be the BEST approach to this application?

  A. Tell the customer cloud A is the best solution

  B. Put it in cloud B and ask the customer to create snapshots every 15 minutes

  C. Both cloud A and cloud B would suit the customer's needs

  D. Change the cloud B disaster recovery solution so RPO will be 15 minutes

  Correct Answer: A

• Question 199:
