Connects to the Internet

Routes packets between different networks

Forwards packets based on IP address

Creates a collision domain per port

Explanation:
A switch creates a separate collision domain for each port, which reduces collisions and improves network efficiency. It operates at the Data Link layer and forwards frames based on MAC addresses.

5 / 40

Explanation:
The command copy running-config startup-config saves the current configuration (running configuration) to the non-volatile memory (NVRAM) as the startup configuration. This ensures that the configuration is retained after a reboot.

7 / 40

Which type of IPv6 address is equivalent to an IPv4 private address?

Link-Local

Unique Local

Multicast

Global Unicast

Explanation:
Unique Local IPv6 addresses are similar to IPv4 private addresses. They are meant for local communication within a site or a group of sites, not meant to be routable on the global Internet. These addresses start with the prefix FC00::/7.

8 / 40

Defined manually by the network administrator

Is more complex to configure than dynamic routing protocols

Automatically adjusts to changes in the network

Uses higher CPU resources on the router

Explanation:
Static routes are manually configured by the network administrator and do not change unless manually altered. They do not automatically adjust to changes in the network, which is a characteristic of dynamic routing protocols.

9 / 40

What is the primary purpose of a VLAN?

To provide wireless connectivity

To increase the speed of the network

Translates the inside global address to the inside local address

Translates the inside local address to the inside global address

Explanation:
The ip nat inside source command translates the inside local address (the address assigned to an internal device) to an inside global address (the address assigned by the NAT router to represent the internal device to the external network). This is a key function of Network Address Translation (NAT).

11 / 40

Which command is used to verify the current NAT translations on a Cisco router?

show nat status

show ip nat translations

set password

Explanation:
The enable secret command is used to set an encrypted password for privileged EXEC mode on a Cisco router. This provides a higher level of security compared to the enable password command, which sets an unencrypted password.

13 / 40

Which feature allows a router to distribute its IP address assignments to hosts on a network?

DHCP

DNS

NAT

Explanation:
DHCP (Dynamic Host Configuration Protocol) allows a router or dedicated DHCP server to dynamically assign IP addresses and other network configuration parameters to hosts on a network.

14 / 40

Which command is used to configure a static route on a Cisco router?

ip route

route add

ip static

add static route

Explanation:
The ip route command is used to configure static routes on a Cisco router. The syntax is ip route [destination network] [subnet mask] [next hop IP address or exit interface].

15 / 40

Which protocol does OSPF use to discover neighboring routers and maintain adjacencies?

UDP

ICMP

Hello Protocol

TCP

OSPF (Open Shortest Path First) uses Hello packets as part of its Hello Protocol to discover and maintain neighbor relationships. These packets are sent periodically out of all OSPF-enabled interfaces. If a router receives a Hello packet from a new neighbor, it will reply with its own Hello packet, and an adjacency will begin to form. If a router does not receive a Hello packet from an already known neighbor within a certain interval, it will consider that neighbor down.

16 / 40
