500-444 Exam Dumps : Cisco Contact Center Enterprise Implementation and Troubleshooting (CCEIT)

Security certificates are used to ensure that browser communication is secure by authenticating clients and servers on the web. There are two ways to deploy security certificates in CCE: Certificate Authority (CA) signed certificates and self-signed certificates1.

• CA signed certificates are certificates that are issued by a trusted third-party entity, such as VeriSign or Thawte, that validates the identity of the certificate owner. CA signed certificates are more secure and reliable than self-signed certificates, but they also require more time and money to obtain and maintain2.
• Self-signed certificates are certificates that are generated and signed by the certificate owner, without involving any third-party entity. Self-signed certificates are easier and cheaper to create and deploy, but they are less secure and trustworthy than CA signed certificates, as they can be easily forged or tampered with2.

CCE supports both CA signed certificates and self-signed certificates for securing the communication between different components, such as AW, CVP, Finesse, ECE, etc. However, some components may require additional steps or configurations to use CA signed certificates, such as importing the CA certificate into the AW machines, changing the Java truststore password, or binding the CA signed certificate in the Diagnostic Portico123.

The other options are not valid ways to deploy security certificates in CCE:

• Security Authority (SA) is not a term related to security certificates, but rather a role that is assigned to a user or a group in CCE to grant them access to certain security features, such as encryption, auditing, or IPsec1.
• 3rd party signed certificates are not a distinct category of security certificates, but rather a synonym for CA signed certificates, as they both involve a third-party entity that signs the certificates2.
• Digitally signed certificates are not a specific type of security certificates, but rather a general characteristic of all security certificates, as they all use digital signatures to verify the authenticity and integrity of the certificate data2.

• Option A is correct because if one side of the ICM Logger fails, the other side can still receive historical data from both sides of the ICM Router. However, the failed side will not be able to receive any data until it is restored1.
• Option B is correct because the Peripheral Gateways (PGs) are connected to both sides of the ICM Router through the private LAN and the visible network. If the private LAN fails, the PGs can use the visible network to communicate with the active ICM Router and determine which side is the master2.
• Option D is correct because the ICM Router uses heartbeats to monitor the status of its duplex pair. If one side does not receive a heartbeat from the other side within a specified time interval, it assumes that the other side has failed and initiates a failover process3.
• Option C is incorrect because if one side of the ICM Logger fails, the impact of call processing is not limited to the corresponding side of the ICM Router. The ICM Router can still process calls using the data from the surviving ICM Logger side1.
• Option E is incorrect because there is some impact on call processing during an ICM Logger failure. For example, some historical reports may not be available, some configuration changes may not be replicated, and some call data may be lost4.
• Option F is incorrect because during an ICM Router failover, calls in progress in Cisco Unified Customer Voice Portal (CVP) are not disconnected. The CVP uses the Survivable Remote Site Telephony (SRST) feature to maintain the calls until the failover is completed5.
