a service that provides on-demand access to shared resources* 208. An administrator wants to configure a router so that users on the external network can only establish HTTP connections to the internal Web site by accessing www.netacad.com:8888. What functionality would the administrator configure to achieve this? 81. What would be the main reason an attacker would launch a MAC address overflow attack? May require a Cisco Responder-compatible target device if the target is not running a UDP echo service on UDP port 7. 160. See exhibition. A network administrator has implemented the configuration in the displayed output. What is missing in the configuration that would prevent OSPF routing updates from being passed to the Frame Relay service provider? 8pm Which cloud service would be best suited for a new business that can`t afford physical servers and network devices and needs to purchase on-demand network services? • Reviews and monitors Quality of Service (QoS) and differentiates service levels. 85. If SNMPv1 or SNMPv2 is used, what functionality provides secure access to MIB objects? 182. What term is used to identify the point at which the customer`s network ends and the service provider`s network begins? This can be something simple like a ping where we check the round trip time, or something more advanced like an RTP VOIP packet where we check the delay, jitter and calculate a MOS score that gives you an indication of what the voice quality will look like.
• Enables customers to deploy new applications and services securely. Performance visibility, reduced deployment time for new applications, improved adoption of mission-critical services, and proactive problem identification increase reliability. 23. When creating an IPv6 ACL, what is the purpose of the latest implicit command entries that allow arbitrary icmp nd-na and icmp all nd-ns? This usually means that the destination does not exist (invalid or inaccessible IP address) or that the answering machine is not enabled on this target device. The SLA video process REQUIRES the responder to be both accessible and functional for the session to start. 213. What inefficient feature of temporal multiplexing does statistical TH overcome? 84. Which SNMP functionality provides a solution to the main disadvantage of SNMP polling? IP SLA (Service-Level Agreement) is an excellent feature on Cisco IOS devices that can be used to „measure“ network performance.
• IP service network health preparation or evaluation path control is the mechanism that changes the default packet forwarding over a network. This is not quality of service (QoS) or MPLS traffic engineering (MPLS-TE). Path control is a set of tools or commands that can be used to modify the routing protocol transfer table or bypass standard packet forwarding. Manipulating routing information may be necessary to improve the resiliency, performance, or availability of your network. Now that you have an idea of what IP SLA is, let`s see how we can set up an operation. The most common operations to measure IP networks. VoIP and video are the main applications. Cisco IOS IP Service Level Agreements (SLAs) enable customers to secure new IP applications and critical IP services that leverage data, voice, and video over an IP network. Cisco has expanded traditional service level monitoring and evolved its IP infrastructure to become compatible with IP applications by measuring both end-to-end and at the IP layer.
225. Which network design module would not normally connect to the service provider`s edge? 18K Which function sends simulated data over the network and measures performance between multiple network sites? 51. See exhibition. A user turns on a PC after waiting and calls the help desk to report that the PC appears unable to access the Internet. The technician prompts the user to issue the arp –a and ipconfig commands. .
