Which four statements indicate unique properties of VLAN 1 on Cisco Nexus switches? (Choose four.)
Which four statements indicate unique properties of VLAN 1 on Cisco Nexus switches? (Choose four.)
VLAN 1 has unique properties on Cisco Nexus switches: VLAN 1 cannot be deleted, it is used for Cisco Discovery Protocol, it is used for VTP advertisements, and it defines a broadcast domain. VLAN 1 is designated as the default VLAN and is used for various control plane applications, including the aforementioned protocols. These properties help in network management and maintain a standardized configuration across devices.
Which command displays the Trunking Native Mode VLAN on port Ethernet 1/18?
To display the Trunking Native Mode VLAN on a specific port, the appropriate command is 'show interface e1/18 switchport'. This command provides detailed interface switchport information, including the Trunking Native Mode VLAN, Access Mode VLAN, Trunking VLANs Allowed, and other relevant configuration details. Therefore, option D is the correct choice for this command.
Which three statements are true concerning RFC 1918 IP addresses? (Choose three.)
RFC 1918 defines IP address ranges for private networks, which are not globally routable. These addresses should be filtered at Internet border interfaces to prevent private addresses from being advertised on the public internet. The specific address blocks defined by RFC 1918 are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.
Which two statements describe the purpose of RFC 1918? (Choose two.)
RFC 1918 establishes a range of IP addresses that are dedicated to use on internal networks, such as private LANs, to help conserve the global pool of IP addresses. By using these private addresses, the pressure on the allocation of globally unique IP addresses is relieved, addressing the shrinking pool of globally routable addresses.
What are three reasons to migrate from IPv4 to IPv6? (Choose three.)
Migrating from IPv4 to IPv6 offers several advantages. Firstly, IPv6 eliminates the requirement for NAT (Network Address Translation), simplifying network configurations and improving performance (Option A). Secondly, the vast address space of IPv6 includes enough IP addresses to allocate more than four billion IP addresses to every person on earth, addressing the issue of address exhaustion faced with IPv4 (Option B). Lastly, IPv6 allows hosts to be assigned an IP address without the need for DHCP, thanks to mechanisms like Stateless Address Autoconfiguration (SLAAC) (Option D). These three reasons underscore the benefits of transitioning to IPv6.
