Cisco 500-444 Exam

The Cisco CiscoCertUtil tool is a command-line utility that can be used to generate Certificate Signing Requests (CSRs), generate self-signed certificates in the PEM format (which is an X509 extension), validate any certificate, and create a log file pertaining to the operations that it performs for troubleshooting. This can be useful for troubleshooting any issues that may arise when generating or validating certificates.

1. to provide validation of certificate requests: A CA is responsible for verifying the identity of an entity before issuing a certificate. This includes verifying the entity's identity, such as by checking government-issued identification or business registration documents.

2. to issue a CA-signed Identity certificates: After validating the entity's identity, the CA issues the certificate, which is signed by the CA's private key. This certificate can be used to authenticate the identity of the entity, establish trust and secure communication.

A: When ICM Logger side A fails, ICM call router side B can't send historical information to ICM Logger side A and is limited to ICM Logger side B. This is because ICM loggers act as a buffer between ICM call routers and the historical data store, and if one side fails, the other side can't send historical data to it. (Reference: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cust_contact/contact_center/icm_enterprise/icm_enterprise_10_5/installation/guide/icm_install/icm_high.html)

D: If one ICM call router of a duplex pair of Cisco Unified ICM call routers fails, the surviving ICM call router recognizes the failure when it receives no response to heartbeats over the private LAN. This is because ICM call routers communicate with each other over a private LAN using heartbeats. If one ICM call router stops sending heartbeats, the other ICM call router knows that it has failed and takes over the processing of calls. (Reference: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cust_contact/contact_center/icm_enterprise/icm_enterprise_10_5/installation/guide/icm_install/icm_high.html)

F: During Cisco Unified ICM call router failover processing, calls in progress in Cisco Unified Customer Voice Portal are disconnected, but all new calls are processed successfully. This is because when a Cisco Unified ICM call router fails, the surviving ICM call router takes over the processing of calls. This can cause calls in progress in Cisco Unified CVP to be disconnected, but new calls will be processed successfully.
