- Voice traffic consumes lots of network resources. Voice traffic does not consume a lot of network resources, such as bandwidth. However, it is very sensitive to delay and dropped packets cannot be retransmitted. For good voice quality, the amount of...Link: https://chegg.com/homework-help/questions-and-answers/engineer-designed-valve-regulate-water-pressure-automobile-engine-engineer-designed-valve--q72881894
- The router will remove the packet in the front of the queue, move all other packets forward, and insert the just arrived packet at the end. The router will drop any packet that arrives at the end of the queue. The router will only drop non...Link: https://covidtesthtx.com/services
- TCP flows are grouped into a single class. Network devices are setup to service multiple classes of traffic where each class of traffic has different QoS requirements. What are two characteristics of the best-effort QoS model? It treats all network packets in the same way. It uses a connection-oriented approach with QoS. It provides preferential treatment for voice packets. It does not provide a delivery guarantee for packets. The best-effort QoS model treats all network packets in the same way. What role do network devices play in the IntServ QoS model? Network devices use QoS on a hop-by-hop basis to provide excellent scalability. Network devices ensure that resources are available before traffic is allowed to be sent by a host through the network. Network devices provide a best-effort approach to forwarding traffic. The IntServ QoS model uses resource reservation to guarantee bandwidth and packet-loss rates from end to end. IntServ uses a connection-oriented approach to ensure that available resources are sufficient in the network for the traffic to have a specific level of QoS.Link: https://jkalerts.com/jammu-kashmir-notifications/jkssb-answer-key-of-cbt-exam-for-various-posts/
- Sep 23, Chapter , Exam answers , It-essentials v7 It-essentials v7. A computer is assigned an IP address of What can be said about the computer, based on the assigned address? It cannot communicate outside its own network. It can communicate with networks inside a particular company with subnets. It has a public IP address that has been translated to a private IP address. The computer can only communicate with other computers connected to the same A technician needs to add a new wireless device to a small WLAN.Link: https://guardant360cdx.com/getting-answers/
- What physical layer medium is used by DSL to provide high-speed data communications? DSL uses a filter to separate the traffic. A user is setting up a home wireless network. Which type of device must the user have in order to establish the wireless network and provide access to the internet for multiple home devices? It will then aggregate the internet access requests from home devices to the internet. A network technician is setting up a web server for a small company. The company has obtained a domain name, company-a.Link: https://academia.edu/35982857/NEW_GRAMMAR_TIME_1
- Ensure that the domain name is successfully resolved. A small company is upgrading its phone system with IP phones. These phones can be used just by plugging into a network port in the offices. Which technology would support the IP phones? A network technician is setting up a wireless access point in the front office of a small company. The technician needs to disable an option on the access point that would allow devices to dynamically add themselves to the network without configuration. Which technology should the technician disable? Although convenient, UPnP is not secure. The UPnP protocol has no method for authenticating devices. In addition, the UPnP protocol has numerous security vulnerabilities. This protocol should be disabled. A small company connects data acquisition equipment to the serial port of a computer.Link: https://blogs.vmware.com/euc/2016/12/irs-approves-vdi-byo-for-federal-tax-information-fti.html
- The equipment user has reported that not all data is being received by the computer. A technician wants to check the serial communication between the equipment and the computer. Which tool can the technician use to troubleshoot the serial communication? In a loopback test, a signal is transmitted through a circuit and then returned to the sending device to test the integrity of the data transmission.Link: https://healthline.com/health/prostate-cancer/pca3-test
- This is because the data link frame address of the remote destination host cannot be used directly. Instead, the IP packet has to be sent to the router default gateway and the router will forward the packet toward its destination. Therefore, if the default gateway is incorrectly configured, the host can communicate with other hosts on the same network, but not with hosts on remote networks. Which characteristic describes the default gateway of a host computer? Match the description to the organization. Not all options are used. It is best known for its standards related to electrical wiring, connectors, and the inch racks used to mount networking equipment. Match the protocol function to the description while taking into consideration that a network client is visiting a web site.Link: https://surveymonkey.com/r/BKBS3PC

- The correct configuration on R1 is: router ospf 10 network What are two reasons that will prevent two routers from forming an OSPFv2 adjacency? Choose two. OSPF network types do not match. There is a missing or incorrect OSPF network command. Mismatched IOS versions, the use of private IP addresses, and different types of interface ports used on a switch are not causes for an OSPF adjacency failing to form between two routers. What does a Cisco router use automatically to create link-local addresses on serial interfaces when OSPFv3 is implemented? Single area OSPFv3 has been enabled on a router via the ipv6 router ospf 20 command. Which command will enable this OSPFv3 process on an interface of that router? In the case the process ID is 20 and the area ID is 0. Fill in the blank. Which command will provide information specific to OSPFv3 routes in the routing table? The show ipv6 route command will show the entire routing table.Link: https://kristinharad.com/runtz-ucm-indictments/create-a-quiz-free.html

- The host name, media state, and description are present even if a DHCP server is not found. A technician is troubleshooting a problem where the user claims access to the Internet is not working, but there was access to the Internet the day before. Upon investigation, the technician determines that the user cannot access the network printer in the office either. The network printer is on the same network as the computer. The computer has What is the most likely problem? The computer cannot communicate with a DHCP server.Link: http://web.pas.rochester.edu/~manly/class/Exams/examfinalfall00.pdf
- The IP default gateway on the computer is incorrect. The network interface card driver needs to be updated. The router that connects this network to other networks is down. Explanation: In a network employing dynamic IP addressing, if a computer cannot communicate with the DHCP server to obtain an IP address, the Windows operating system automatically assigns a link-local IP, which is in the range of In this case, the computer can only communicate with computers connected to the same network within this IP address range. A user can print to a printer that is on the same network, but the traffic of the user cannot reach the Internet. What is a possible cause of the problem? The PC default gateway address is missing or incorrect.Link: https://dumpsinsider.com/aci/3I0-008-test-simulator
