Document Content and Description Below

What are the best practices for media storage and restore operations? Label backup media with Physical and electronic labels. Verify that the source data is the same as the destination data. Te... st whether you can restore data from the back-up media. Apply strategies for tape rotation and retention. What are some best practices for managing cables? Cables should be labelled to identify their purpose. To avoid damage, the cable bend radius should not be exceeded. Cables should be grouped with cable ties for better airflow. what range do registered ports fall into? 1,024 to 49,151 Which statements describe a default gateway? It is a type of network device it's used to send data off the network It can be viewed with the ipconfig utility Which statements describe the Media Access Control (MAC) address? It's a layer 2 address It is the first half of the manufacture ID It can be viewed using the ipconfig command It is represented as a 12-character hexadecimal address Which statements are true about public and private IP addressing? Public IP address is an IP address that is rout-able on the internet Any system that uses a private IP address cannot send its packets out to the internet Private IP addresses are provided for internal communication within a organization's network what are the considerations for using a Network Interface Card (NIC)? By default, most network cards detect the duplex state of the system they connect to. Some NICs support multiple speed settings. The full duplex setting allows information to be sent and received at the same time. NIC teaming provides performance and redundancy benefits. Which statements are true about backup media? It takes more time to backup to tape than to disc or optical media. Optical media are commonly used to archive data that isn't going to be used on a regular basis. A common scenario is to backup a server to a disk , and backup it up to tape in the background. Match the three main NetBIOS services to their descriptions. NetBIOS datagram distribution service - Does not guarantee data delivery - Sends data to a remote system NetBIOS session service - Guarantees data delivery - Sends data to a remote system NetBIOS name service - Registers and resolves computer names Which statements are true about disaster recovery replication methods? Asynchronous replication offers better performance than synchronous replication. Asynchronous replication requires that a change is written to one location before it is sent to the other location. Synchronous replication requires that a change is written in both places before the change is considered successful. Data can be replicated to another disk, server, or site. what are the characteristics of the TCP and UDP network services? TCP operates at the transport layer of the TCP/IP protocol stack. UDP is a connectionless protocol. TCP requires an acknowledgment for every packet that is sent. TCP is a connection-oriented protocol. UDP is faster than TCP. Which statements describes how network address translation (NAT) and port address translation (PAT) work? PAT maintains separate entries for each session by recording the source and destination ports of the sessions. NAT is used to translate private IP addresses to the public IP addresses. PAT is an extension to NAT that permits multiple devices on a network to be mapped to a single public IP address. NAT is a router-based service that allows a router to change the IP addresses of the packets that they send. Which statement is true about copper cables? CAT5 is used in a 100-megabit Ethernet or Fast Ethernet environments. CAT6 is used in 10-gigabit Ethernet environments. A rollover cable is used to connect to the console port on a Cisco device.
