2) It inserts a 4-byte header after the source MAC address in the original Ethernet frame, which carries the VLAN information.

Which one of the following statements best describes how 802.1q incorporates VLAN information onto an Ethernet frame? 1) It uses a special EtherType to identify the Ethernet payload that contains the 802.1Q tag. 2) It inserts a 4-byte header after the source MAC address in the original Ethernet frame, which carries the VLAN information. 3) The VLAN information is identified in the Ethernet header Type/Length field. 4) It encapsulates the entire Ethernet frame and adds a 4-byte header before the destination MAC address which carries the VLAN information.

2) A default route is an optional entry that is used when no explicit path to a destination is found in the routing table.

Which one of the following statements best describes the purpose of a default route? 1) A default route sets the preferred path for multicast packets. 2) A default route is an optional entry that is used when no explicit path to a destination is found in the routing table. 3) A default route will flood the packet out of all connected ports. 4) A default route is just a placeholder in the route table until a new route is found.

1) ACLs provide packet filtering for routers and firewalls to protect internal networks from the outside world. 3) ACLs provide a basic level of security and control the packets that pass through the routers or firewalls, preventing them from getting to the different parts of the network. 4) At a minimum, it is important to configure the ACLs on the network edge routers or firewalls.

(Choose three.) 1) ACLs provide packet filtering for routers and firewalls to protect internal networks from the outside world. 2) ACLs are used to perform stateful packets inspections and filtering on routers and firewalls. 3) ACLs provide a basic level of security and control the packets that pass through the routers or firewalls, preventing them from getting to the different parts of the network. 4) At a minimum, it is important to configure the ACLs on the network edge routers or firewalls. 5) ACLs can be applied only at the inbound direction and not at the outbound direction.

3) The primary function of a DHCP relay agent is to relay the DHCP messages from the local DHCP clients to the remote DHCP servers. 5) When the DHCP relay agent receives a broadcast packet from a connected client, it changes the giaddr field from zero to the relay agent IP address, and forwards the message to the DHCP server.

Which two if the following statements are true regarding the DHCP relay agent? (Choose two.) 1) DHCP relay is required if the DHCP clients and the DHCP servers are located in the same broadcast domain. 2) The DHCP server uses the ciaddr IP address to select an IP address pool from which to assign the IP addresses to the DHCP client. 3) The primary function of a DHCP relay agent is to relay the DHCP messages from the local DHCP clients to the remote DHCP servers. 4) DHCP discovery messages are broadcasted from the DHCP relay agent to the DHCP servers. 5) When the DHCP relay agent receives a broadcast packet from a connected client, it changes the giaddr field from zero to the relay agent IP address, and forwards the message to the DHCP server.
