What is the default behavior of a Layer 2 switch when a frame with an unknown destination MAC address is received?

A. The Layer 2 switch forwards the packet and adds the destination MAC address to its MAC address table. B. The Layer 2 switch sends a copy of a packet to CPU for destination MAC address learning. C. The Layer 2 switch floods packets to all ports except the receiving port in the given VLAN. D. The Layer… Read More »

When configuring IPv6 on an interface, which two IPv6 multicast groups are joined? (Choose two.)

A. 2000::/3 B. 2002::5 C. FC00::/7 D. FF02::1 E. FF02::2 Answer: Option D, E. Explanation:  When an interface is configured with IPv6 address, it automatically joins the all nodes (FF02::1) and solicited-node (FF02::1:FFxx:xxxx) multicast groups. The all-node group is used to communicate with all interfaces on the local link, and the solicited-nodes multicast group is required for link-layer… Read More »

Which command automatically generates an IPv6 address from a specified IPv6 prefix and MAC address of an interface?

A. ipv6 address dhcp B. ipv6 address 2001:DB8:5:112::/64 eui-64 C. ipv6 address autoconfig D. ipv6 address 2001:DB8:5:112::2/64 link-local Answer: Option C. Explanation:  The “ipv6 address autoconfig” command causes the device to perform IPv6 stateless address auto-configuration to discover prefixes on the link and then to add the EUI-64 based addresses to the interface. Addresses are configured depending on… Read More »

UDP provides reliable message transfer, and TCP is a connectionless protocol. D. UDP uses SYN, SYN ACK, and FIN bits in the frame header while TCP uses SYN, SYN ACK, and ACK bits. Answer:… Read More »

A frame that enters a switch fails the Frame Check Sequence. Which two interface counters are incremented? (Choose two.)

A. input errors B. frame C. giants D. CRC E. runts Answer: Option A, D. Explanation:  Whenever the physical transmission has problems, the receiving device might receive a frame whose bits have changed values. These frames do not pass the error detection logic as implemented in the FCS field in the Ethernet trailer. The receiving device discards the… Read More »

Which statement identifies the functionality of virtual machines?

A. The hypervisor communicates on Layer 3 without the need for additional resources. B. Each hypervisor can support a single virtual machine and a single software switch. C. The hypervisor can virtualize physical components including CPU, memory, and storage. D. Virtualized servers run most efficiently when they are physically connected to a switch that is separate from the… Read More »
