Cisco Updated 200-301 Exam Questions and Answers by oakley

A hypervisor abstracts the physical server hardware and presents virtual hardware to each virtual machine. That includes CPU, memory, storage, and virtual network interfaces. The virtual machine sees a logical machine, while the hypervisor schedules and allocates the real physical resources underneath it. This is the core function of server virtualization and is part of Cisco CCNA 200-301 v1.1 Network Fundamentals because modern network engineers must understand how servers connect through virtual switches and how traffic leaves a hypervisor toward the physical network. A hypervisor is not limited to one VM, and it does not magically communicate at Layer 3 without network resources. The idea that virtualized servers run best only when connected to a separate physical switch misunderstands virtualization; VM traffic can be switched inside the host through a virtual switch before reaching a physical NIC. The correct statement is that the hypervisor virtualizes physical components so multiple independent workloads can run on one host.

VRRP uses the virtual MAC address format 0000.5E00.01xx, where xx is the VRRP group number in hexadecimal. Option A, 0000.5E00.010a, matches that reserved VRRP pattern and represents group 10. Cisco HSRP uses a different well-known format, commonly 0000.0C07.ACxx for HSRP version 1, which is why option C points toward HSRP rather than VRRP. The other choices do not match the VRRP virtual MAC structure. In first-hop redundancy, the virtual IP address is used by hosts as their default gateway, while the virtual MAC address lets Layer 2 forwarding continue to work when the active gateway changes. CCNA 200-301 v1.1 IP Connectivity requires candidates to identify FHRP concepts including HSRP and VRRP. The verified answer is A. Reference: Cisco First Hop Redundancy Protocol behavior and VRRP virtual MAC addressing.

Use A for this item. In a hub-and-spoke WAN, spoke sites communicate through a central hub rather than direct spoke-to-spoke links. This structure lets the hub enforce routing, policy, inspection, and access restrictions between subscriber or branch sites. In Cisco CCNA 200-301 v1.1, Network Fundamentals questions frequently test the practical boundary between similar features: what the feature does, where it is configured, and what problem it is meant to solve. The topology does not inherently provide direct connections between every subscriber; that is closer to full mesh. A clean way to validate the answer is to map the wording of the scenario to the actual device function. If the feature supplies addressing, forwarding, authentication, trunking, route selection, or controller communication, the answer must match that function exactly rather than a nearby protocol name.

SW-1

SW-1# configure terminal

SW-1(config)# interface Ethernet0/0

SW-1(config-if)# switchport trunk allowed vlan 5,6

SW-1(config-if)# exit

SW-1(config)# interface Ethernet0/1

SW-1(config-if)# switchport trunk native vlan 77

SW-1(config-if)# end

SW-1# copy running-config startup-config

SW-2

SW-2# configure terminal

SW-2(config)# interface Ethernet0/1

SW-2(config-if)# switchport trunk native vlan 77

SW-2(config-if)# exit

SW-2(config)# interface Ethernet0/2

SW-2(config-if)# switchport trunk allowed vlan 6

SW-2(config-if)# end

SW-2# copy running-config startup-config

SW-3

SW-3# configure terminal

SW-3(config)# interface range Ethernet0/0 - 1

SW-3(config-if-range)# channel-group 34 mode active

SW-3(config-if-range)# end

SW-3# copy running-config startup-config

SW-4

SW-4# configure terminal

SW-4(config)# interface range Ethernet0/0 - 1

SW-4(config-if-range)# channel-group 34 mode passive

SW-4(config-if-range)# end

SW-4# copy running-config startup-config

Verification commands:

SW-1# show interfaces trunk

SW-2# show interfaces trunk

SW-3# show etherchannel summary

SW-4# show etherchannel summary

SW-3# show interfaces port-channel 34

SW-4# show interfaces port-channel 34

The command switchport trunk allowed vlan 5,6 replaces the default allowed-VLAN list on SW-1 Ethernet0/0 so that only VLANs 5 and 6 can cross that trunk. The same command with VLAN 6 restricts SW-2 Ethernet0/2 to VLAN 6. Cisco documents that all VLANs are permitted on a trunk by default and that switchport trunk allowed vlan vlan-list defines the permitted list. The native VLAN must match at both ends of an 802.1Q trunk, so VLAN 77 is configured on Ethernet0/1 of both SW-1 and SW-2.

For LACP, active initiates negotiation and passive only responds. Therefore, SW-3 must use channel-group 34 mode active, while SW-4 must use channel-group 34 mode passive. Cisco confirms that active-to-passive forms an EtherChannel, whereas passive-to-passive does not. Because the physical interfaces are already identically configured as trunks, no trunk commands should be replaced during channel creation. The channel-group command creates and binds the physical members to logical Port-Channel 34.
