Geben Sie an, welches BGP-Attribut verwendet wird, um externe EBGP-Nachbarn (Peers) über den besten Pfad für eine bestimmte Route innerhalb des autonomen Systems (AS) zu informieren. MED. Local preference. AS path. Next-hop. Origin.

Im BGP-Protokoll entspricht eine Sammlung verbundener IP-Routing-Präfixe unter der Kontrolle eines oder mehrerer Netzwerkbetreiber im Auftrag einer einzelnen Verwaltungseinheit oder Domäne, die eine gemeinsame und klar definierte Routing-Richtlinie für das Internet präsentiert,. IANA. autonomous system. next hop. atomic aggregate. multi-exit discriminator.

In a 48-bit MAC address used as the destination of an Ethernet frame, the least significant bit of the first octet is used to. determine whether the transmission is unicast or multicast. uniquely identify the network interface among those produced by the same manufacturer. indicate whether the frame payload corresponds to the IPv4 or IPv6 protocol. identify the address format version. identify the network interface manufacturer.

An Ethernet frame, according to the IEEE 802.3 standard, has a field designed to detect corrupted data. This field, called Frame Check Sequence, is located. in the preamble. in the frame header, before the destination MAC address. in the frame header, between the destination MAC address and the source MAC address. in the frame header, after the source MAC address. after the payload.

Select the alternative that presents the elements of a Network Access Control (NAC) system. IP (Internet Protocol), MAC Address, Netmask. Browser, user, server. HTTPS (Hypertext Transfer Protocol Secure), NAT (Network Address Translation). IP (Internet Protocol), Firewall, NAS (Network-Attached Storage). Access Requestor (AR), Policy Server, Remote Access Server (RAS).

A network sniffer software displayed the following snippet in its output about a captured packet containing a DNS query. The purpose of this query is to obtain. The domain name (reverse DNS) relative to IP address 192.168.170.20. An email server that serves the NetBSD.org domain. an IPv6 address associated with the domain www.netbsd.org. an IPv4 address associated with the domain www.netbsd.org. The MAC Address of the device whose IP address is 192.168.170.20.

One method for assigning IPv6 addresses is called Stateless Address AutoConfiguration (Slaac). It can use a modified EUI-64 identifier for the IPv6 address interface identification as one of the available options. Using modified EUI-64 is a way to help ensure that any address automatically generated in a subnet is unique. Considering the Slaac method via EUI-64, identify between the options below, the IPv6 address associated with subnet 2001: DB8: Cafe ::/64 and interface MAC address 22: AC: 9e: 18: BE: 80. 2001:DB8:CAFE:20AC:9EFF:FF18:BE80/64. 2001:DB8:CAFE:22AC:9EFF:FE18:BE80/64. 2001:DB8:CAFE:20AC:9EFF:FE18:BE80/64. 2001:DB8:CAFE:22AC:9EFF:FF18:BE80/64. 2001:DB8:CAFE:22AC:9EFF:FF18:BE82/64.

Analyze the topology in the figure to the left. When PC-A transmits a packet to the WWW server, it adds the destination MAC and IP addresses, respectively. 00:12:44:18:18:11 e 172.18.18.2. 01:0B:0C:04:05:06 e 172.18.18.2. 00:12:44:18:18:22 e 172.18.18.1. 00:12:44:18:18:22 e 172.18.18.2. AA:BB:DD:EE:FF:11 e 172.18.18.1.

In Ethernet networks, the EtherType field of Ethernet II frames is responsible for. identifying the transmission rate of the network interface that sent the frame, allowing synchronization of the receiver clocks on the network. identifying the manufacturer of the network interface that sent the frame. signaling the start of a frame, occurring before the destination MAC Address field. identifying the source MAC Address, that is, the network interface that sent the frame. identifying the upper-layer protocol to which the data encapsulated in the frame refers.

Which of the protocols listed below allows the sharing of multicast data sources between RPs (Rendezvous Points) from different multicast domains? note: MSDP is specifically designed to enable RPs in different multicast domains to share information about active multicast sources, facilitating inter-domain multicast communication. In contrast, PIM-DM (Protocol Independent Multicast - Dense Mode) is used for routing multicast traffic within a single domain. a- msdp. b- pim-dm.

Which of the alternatives below presents a protocol for controlling the distribution of multicast messages on a local network?. IGMP. PIM.
