Pass the Cisco CCEIT 500-444 Questions and answers with ValidTests

 According to the Cisco Packaged Contact Center Enterprise Installation and Upgrade Guide, Release 12.0 (1), there are two considerations for PCCE 2K installation:

You need to add PGs via PG setup after installing the software. This is because the PG setup tool allows you to configure the PGs for different types of peripherals, such as CUCM, CVP, and Finesse. You can also configure the network interface cards, the PG redundancy, and the PG security settings using the PG setup tool1.

You need to run Websetup after installing the software. This is because the Websetup tool allows you to configure the PCCE components, such as the Router, Logger, AW-HDS-DDS, and CVP. You can also configure the call routing scripts, the dialed number plan, the agent teams, and the skill groups using the Websetup tool2.

You do not need to add Router Logger after installing the software, because the Router Logger is automatically installed and configured during the PCCE installation process3. You do not need to run Domain Manager tool, add root, facility, and instance, because the Domain Manager tool is only used for UCCE installations, not PCCE installations4. You do not need to install ICM/CCE software on all ICM/CCE servers, because the PCCE installation process automatically installs the ICM/CCE software on the required servers3.

Answer: B

The sync job that runs every 10 minutes to bring back the OUT_OF_SYNC machine to the IN_SYNC state is the Automated differential sync job. This sync job compares the configuration of the Packaged CCE components on the primary and secondary nodes and applies the changes to the secondary node if there is any difference. The Automated differential sync job is enabled by default and runs every 10 minutes. It can also be triggered manually from the SPOG UI12.

Certificate Authority (CA) signed certificates are less administration in environments with many servers, such as CCE, because they are issued by a trusted third-party entity that validates the identity of the certificate owner and provides a chain of trust. CA signed certificates are more secure and reliable than self-signed certificates, which are generated by the same entity whose identity they certify and are not verified by anyone else. Self-signed certificates require manual installation and configuration on each server and client that needs to communicate with them, which can be tedious and error-prone. 3rd party signed certificates are similar to CA signed certificates, but they are issued by a commercial entity that may charge a fee for their services. Security Authority (SA) is not a valid term for a certificate issuer. References: 1, 2, 3

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 readiness for the CCE deployment can be verified in the CCE Web Admin -> Infrastructure - Inventory page. This page shows the list of machines that are part of the CCE deployment, including their roles, IP addresses, hostnames, and status. The status indicates whether the machine is online, offline, or in maintenance mode. The inventory page also allows adding, editing, or deleting machines from the system inventory. To access the inventory page, follow these steps:

From your desktop, double-click the Unified CCE Tools icon, and then select Administration Tools.

Double-click the CCE Web Administration link.

In the Unified CCE Administration, navigate to Overview > Infrastructure Settings, click Inventory.

 A push sync is triggered when an administrator performs any create, update, or delete operation on a specific configuration item. A push sync sends the configuration changes to all the nodes in the PCCE deployment. A push sync is also triggered when an administrator adds or removes a node from the deployment.

The correct tools to download logs for CCE troubleshooting are:

Diagnostic framework portico: This is a web-based interface that allows you to access various diagnostic tools and logs for CCE components. You can use it to run diagnostic tests, collect logs, view system status, and troubleshoot issues1.

Unified System CLI: This is a command-line interface that allows you to access diagnostic tools and logs for CCE components from a single point of entry. You can use it to run diagnostic tests, collect logs, view system status, and troubleshoot issues2.

RTTEST: This is a command-line tool that allows you to monitor the real-time status of CCE components and processes. You can use it to view the state of calls, agents, peripherals, routes, and scripts3.

The CiscoCertUtil tool is a utility that helps you manage certificates on any Contact Center Enterprise machine for machine-to-machine secure communication across components. Some of the functions of the CiscoCertUtil tool are:

It generates certificate signing requests (CSR) that can be submitted to a certificate authority (CA) for obtaining CA-signed certificates. A CSR is a message sent from an applicant to a CA in order to apply for a digital identity certificate. It usually contains the public key for which the certificate should be issued, identifying information (such as a domain name) and integrity protection (such as a digital signature).

It generates self-signed certificates in the PFX format, which is a binary format for storing the server certificate, any intermediate certificates, and the private key in one encryptable file. PFX is an acronym for Personal Information Exchange. PFX files are typically used on Windows machines to import and export certificates and private keys.

It creates a log file pertaining to the operations that it performs for troubleshooting. The log file is located in the \icm\bin\CiscoCertUtil.log folder. The log file contains information such as the date and time of the operation, the command executed, the parameters used, the status of the operation, and any error messages.

It validates any certificate that is installed on the machine. It checks the validity period, the signature, the trust chain, and the revocation status of the certificate. It also displays the certificate details such as the subject, the issuer, the serial number, the thumbprint, and the public key.

Dial-peers are the configuration objects that define the dial plan on a Cisco Voice Gateway/CUBE. Dial-peers are used to match the incoming and outgoing calls based on the destination patterns, and to apply the dial-peer attributes, such as codec, digit manipulation, voice-class, and call routing. Dial-peers can be of different types, such as POTS (Plain Old Telephone Service), VoIP (Voice over IP), or VXML (Voice XML). ATR, voice-class, and Voip voice are not the objects that define the dial plan, but they are some of the attributes that can be applied to the dial-peers.

When deploying Direct Attached Storage (DAS) only systems, it is important to remember that failure of a VM brings down all the components that are installed on the VM. This is because DAS is a type of storage that is connected directly to the computer accessing it, such as a PC or server, as opposed to storage that is accessed over a network, such as network-attached storage (NAS) or storage area network (SAN). DAS provides fast and low-latency access to the data, but it also limits the scalability and availability of the system. If a VM fails, the data stored on the DAS attached to that VM becomes inaccessible to other VMs or applications. Therefore, it is essential to have a backup and recovery strategy for the data on the DAS, as well as a high availability design for the VMs123. References: Solution Design Guide for Cisco Unified Contact Center Enterprise, Release 12.6 (1)1, Direct-Attached Storage (DAS): What is it?4, Share an Azure managed disk across VMs2.
