The CLI command that manages the Java Keystore Certificate in Windows CCE servers is keytool. Keytool is a utility that is included in the Java Runtime Environment (JRE) and allows you to create, import, export, list, and delete certificates, keys, and keystores. A keystore is a repository of security certificates that can be used for SSL/TLS communication. The Java Keystore Certificate is the default keystore that is used by the Java applications running on the Windows CCE servers, such as the Web Setup tool, the Diagnostic Framework Portico, and the Unified Intelligence Center12. To use keytool, you need to open a command prompt window and navigate to the JRE bin directory, which is typically located at C:\Program Files\Java\jre\bin. Then, you can use the keytool command with various options and parameters to perform the desired operations on the Java Keystore Certificate34. References: Security Guide for Cisco Unified ICM/Contact Center Enterprise, Release 12.5 (1) and 12.5 (2)1, Implement CA Signed Certificates in a CCE 12.6 Solution2, SSL Certificate Installation - Java Based Web Servers - DigiCert3, Keytool - Oracle Help Center4.

A SIP proxy server is a component of a SIP network that handles the setup and termination of calls between SIP devices. It also performs functions such as registration, authorization, network access control, and network security. Some of the functions of a SIP proxy server are:

• Centralizes dial plans: A SIP proxy server can centralize the dial plans for a SIP network, meaning that it can translate and route calls based on a unified set of rules and policies. This simplifies the administration and management of the SIP network and ensures consistent call routing across different devices and locations.
• Helps to centralize the administration and call control: A SIP proxy server can also help to centralize the administration and call control of a SIP network, meaning that it can provide a single point of contact and configuration for all the SIP devices and endpoints. This reduces the complexity and overhead of maintaining multiple SIP servers and devices and allows for easier monitoring and troubleshooting of the SIP network.

According to the Cisco documentation12, single sign-on (SSO) in PCCE can be implemented in one of these three modes:

• SSO - Enable all agents and supervisors in the deployment for SSO. This mode requires the use of SAML assertions to exchange authentication and authorization details between an identity provider (IdP) and an identity service (IdS)1.
• SAML - Security Assertion Markup Language (SAML) is an XML-based standard that allows the IdP to issue SAML assertions, which are packages of security information transferred from the IdP to the service provider for user authentication1. SAML is the underlying technology that enables SSO in PCCE2.
• Hybrid - Enable agents and supervisors selectively in the deployment for SSO. Hybrid mode allows you to phase in the migration of agents from a non-SSO deployment to an SSO deployment and enable SSO for local PGs. Hybrid mode is useful if you have third-party applications that don’t support SSO, and some agents and supervisors must be SSO-disabled to sign in to those applications1.

Option A is incorrect because Non-SSO is the opposite of SSO, and it means continuing to use existing Active Directory-based and local authentication, without SSO1. Option C is incorrect because ldS is a typo for IdS, which is not a mode but a component of SSO. Option D is incorrect because ldP is a typo for IdP, which is also not a mode but a component of SSO.

 = In order to configure SAML SSO for PCCE, you need to create claim rules that specify the claims sent from ADFS to Cisco Identity Service as part of a successful SAML assertion. The claim rules define how to transform the incoming claims from the AD FS identity provider into the outgoing claims that are expected by the Cisco Identity Service relying party. The two claim rules that are required for PCCE are:

• sAMAccountName - Logon names maintained for backward compatibility. This claim rule maps the sAMAccountName attribute from the AD FS identity provider to the uid attribute in the outgoing claim. The uid attribute is used to identify the authenticated user in the claim sent to the applications. The sAMAccountName attribute is the logon name used to support clients and servers from a previous version of Windows1.
• E-Mail Address - For the Outgoing claim type. This claim rule maps the E-Mail-Addresses attribute from the AD FS identity provider to the mail attribute in the outgoing claim. The mail attribute is used to provide the email address of the authenticated user in the claim sent to the applications. The E-Mail-Addresses attribute is the primary email address of the user2.

The other options are not valid claim rules for PCCE. The user_principal option is not a valid attribute name in AD FS. The Unspecified option is not a valid claim type in AD FS. The uid option is not a valid attribute name in AD FS, but it is the outgoing claim type that is mapped from the sAMAccountName attribute.

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.

A certificate authority (CA) is a trusted entity that issues digital certificates for websites and other entities. CAs validate a website domain and, depending on the type of certificate, the ownership of the website, and then issue TLS/SSL certificates that are trusted by web browsers like Chrome, Safari and Firefox. Thus, CAs help keep the internet a safer place by verifying websites and other entities to enable more trust in online communications and transactions. Some of the roles of a CA in a trusted third-party CA certificate are:

• To provide validation of certificate requests: A CA verifies the identity and authenticity of the certificate requester before issuing a certificate. The CA may use different methods of validation, such as domain validation, organization validation, or extended validation, depending on the type and level of assurance of the certificate. The CA may also check the revocation status of the certificate or the certificate chain to ensure that the certificate is not expired or revoked.
• To issue a CA signed Identity certificates: A CA signs the certificate with its own private key, which attests to the validity and integrity of the certificate. The CA also provides the certificate with a serial number, a validity period, and other attributes. The CA signed certificate can be used by the certificate holder to prove its identity and establish secure connections with other parties.

The PCCE production deployment model on an ESXi server requires two validations: ensuring that the correct servers are on the correct sides and verifying that the correct RAM and CPU are being deployed. These validations are necessary to ensure that the PCCE components are configured properly and have sufficient resources to run smoothly. The other options are not relevant for the PCCE production deployment model on an ESXi server. Linux verification for containers is not applicable because PCCE does not use containers. The hypervisor provides enough power is not a validation step, but a prerequisite for the ESXi server. The lab is deployed properly is not a validation for the production deployment model, but for the lab deployment model. References: Virtualization for Cisco Packaged CCE Release 11.6(x)1, Deployment Type Info API2.

 The deployment team is responsible for ensuring that servers designated for use by CCE VMs meet the requirements, including but not limited to Storage System Performance and IOPS (Input/Output Operations Per Second) Requirements. The deployment team is the group of engineers who install, configure, and test the CCE solution at the customer site. They must follow the design specifications and guidelines provided by the design team, and verify that the hardware and software components are compatible and meet the performance and capacity requirements. The deployment team must also ensure that the CCE VMs are deployed on the appropriate servers and have the correct network and storage configurations1. References: Troubleshooting Cisco Contact Center Enterprise (CCET) course outline2, Virtualization for Cisco Packaged CCE Release 11.6(x)1.

External voice DNs are sourced from CUCM in a CCE Dial Plan. External voice DNs are the DNs that are not associated with any CCE device, such as agent phones, VRU peripherals, or gateways. They are used to route calls to destinations outside the CCE network, such as PSTN numbers, voicemail, or other PBXs. CUCM is responsible for provisioning and managing these DNs and assigning them to the appropriate devices or trunks. CVP can also use external voice DNs to send calls to CUCM for further routing or treatment.

A voice gateway (VGW) is a device that connects a traditional telephony network, such as a TDM trunk, to a voice over IP (VoIP) network, such as a Cisco Unified Communications Manager (CUCM) cluster. A VGW performs signaling and media conversion between the two networks, and can also provide supplementary services, such as call routing, digit manipulation, transcoding, conferencing, and fax relay. A VGW can be a standalone device, such as a Cisco Integrated Services Router (ISR), or a software module, such as a Cisco Unified Border Element (CUBE). A CUBE is a special type of VGW that can also provide security, demarcation, and interworking functions for VoIP calls. A CUBE can be deployed between two VoIP networks, such as CUCM and a service provider SIP trunk, or between a TDM trunk and a VoIP network, in which case it acts as both a CUBE and a VGW. A CUCM is not a VGW, but a call control platform that manages VoIP endpoints, such as IP phones, and interacts with VGWs for call routing and signaling. A CUSP is a Cisco Unified SIP Proxy, which is a device that provides SIP routing and load balancing for VoIP networks. A CUSP is not a VGW, but a SIP proxy server that can work with CUCM and CUBE to optimize SIP call flows. References:

 The keytool command that lists certificates in the cacerts file is B: keytool -list -keystore cacerts. This command will display the aliases and fingerprints of all the certificates in the cacerts file, which is the default truststore for Java applications1. The cacerts file contains the root and intermediate certificates of various certificate authorities (CAs) that are trusted by Java2.

The other options are incorrect because:

• A: keytool -list -showinfo is not a valid keytool command, as the -showinfo option does not exist. The closest option is -v or -verbose, which will display more details about each certificate, such as the owner, issuer, serial number, validity period, signature algorithm, and extensions1.
• C: keytool -list cacerts is not a complete keytool command, as it is missing the -keystore option, which is required to specify the name or path of the keystore file to be listed. Without the -keystore option, the keytool command will assume the default keystore file, which is usually named .keystore in the user’s home directory1.
• D: keytool -list -alias is also not a complete keytool command, as it is missing the value of the -alias option, which is used to specify the alias of a particular entry in the keystore file to be listed. Without the value of the -alias option, the keytool command will display an error message, such as "keytool error: java.lang.Exception: Alias does not exist"1.

n Contact Center Enterprise with Cisco Unified Customer Voice Portal (CVP) and Cisco Unified Border Element (CUBE) deployment, CUBE must be configured as media pass flow-through mode. This means that CUBE will terminate and reoriginate both the signaling and media streams for each call leg. This allows CUBE to perform media manipulation, such as transcoding, transrating, DTMF interworking, and media forking. Media pass flow-through mode is required for CUBE to support advanced features for contact center, such as courtesy call back, contact center survivability, and encrypted (SRTP) trunks. Media pass flow-around mode, where CUBE only terminates and reoriginate the signaling stream and lets the media stream bypass CUBE, is not supported for contact center solutions. A voice gateway must not be dedicated for VXML browser sessions, as CUBE can coexist with VXML gateway on the same platform. Box-to-box CUBE can be used for redundancy, but it is not a mandatory configuration for contact center solutions123. References:

• 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.

The Single Pane of Glass (SPOG) is the web-based administrative interface that should be deployed to provide a unified and simplified view of the Unified CCE system, even though Unified CCE provides Configuration Manager as the legacy User Interface for administrators1. The SPOG is also known as the CCE Web Administration or the Unified CCE Administration console, and it allows administrators to configure and manage various Unified CCE features and settings, such as agents, attributes, precision queues, bucket intervals, media routing domains, license, bulk jobs, deployment type, system information, single sign-on, context service, and contact center AI23.

The other options are incorrect because:

• A: WebSetup is not a web-based administrative interface, but rather a tool that is used to install and configure the web setup components, such as the web setup database, the web setup service, and the web setup client, on the Unified CCE servers. WebSetup is used to perform initial configuration tasks, such as setting the deployment type, the instance name, the security mode, the license server, and the LDAP directory4.
• B: Contact Centre Management Portal (CCMP) is not a web-based administrative interface for Unified CCE, but rather a separate product that provides a web-based interface for managing Cisco Unified Contact Center Express (UCCX) and Cisco Unified IP Interactive Voice Response (IP IVR) systems. CCMP allows administrators to perform tasks such as creating and modifying scripts, applications, triggers, teams, skills, and CSQs, as well as monitoring and reporting on the system performance and agent activity5.
• C: LDAP Plugin is not a web-based administrative interface, but rather a component that enables Unified CCE to integrate with an external LDAP directory, such as Microsoft Active Directory, for user authentication and authorization. LDAP Plugin allows Unified CCE to synchronize user data from the LDAP directory and assign roles and permissions to the users based on their LDAP group membership2.

A PCCE initialization under Unified CCE PG performs the following two tasks among others:

• Creates the CUCM Peripheral Gateway (PG) with the CUCM PIM. A CUCM PG is a component that communicates with the Cisco Unified Communications Manager (CUCM) to control and monitor agent phones and route calls. A CUCM PIM is a process that runs on the CUCM PG and acts as an interface between the CUCM and the CTI Server. The PCCE initialization creates the CUCM PG with the CUCM PIM and configures the required settings, such as the JTAPI username and password, the CUCM cluster ID, and the PG ID12.
• Downloads JTAPI from the Unified Communications Manager and installs it on the Unified CCE PG. JTAPI is a Java API that enables computer telephony integration (CTI) applications to interact with the CUCM. The PCCE initialization downloads the JTAPI client from the CUCM publisher and installs it on the Unified CCE PG. This allows the CUCM PIM to use JTAPI to control and monitor agent phones and route calls13.
