1. What are the similarities of DHCP and BOOTP?

They work in client/server model.

They work in static address allocation mode.

They can dynamically obtain IP addresses.

They use the same packet structure.

2. When a client applies for an IP address through DHCP, which message is the unicast message?

DHCP OFFER

DHCP REQUEST

DHCP DISCOVER

None of the above

3. What are the functions of DHCP snooping?

Defend against DoS attacks initiated by changing the CHADDR field

Defend against bogus DHCP server attacks

Defend against ARP attacks

Defend against man-in-the-middle attacks and IP/MAC spoofing attacks

4. If only some devices on a network run MPLS (MPLS domain is encapsulated in the IP packet header), labels are generated only for direct routes of devices running MPLS. Labels are not generated for the routes originated from other devices running IP protocols.

True

False

5. Based on the routing information exchange mode, MPLS VPNs are usually classified into two types. One is the overlay VPN. Which is the other type of MPLS VPN?

L2 VPN

L3 VPN

Peer-to-Peer VPN

Virtual Private Network

6. The core of the MPLS technology is label switching.

True

False

7. What about all outgoing labels in the label forwarding table of a device for the same route with the same next hop?

They must be different.

They must be the same.

They may be the same.

8. What about all outgoing labels in the label forwarding table of a device for different routes with the same next hop?

They must be different.

They must be the same.

They may be the same.

9. What is the POP action in MPLS?

The top label is removed from the MPLS label stack.

The top label is added to the MPLS label stack.

The top label is replaced with another value.

The top label is replaced with the label of another group

10. Which of the following statements about the VRRP working process is false?

The router with the highest priority is elected as the master router.

The master router sends gratuitous ARP packets to inform connected devices or hosts of its virtual MAC address.

If the master router fails, the backup router with the highest priority is elected as the new master router.

To ensure fast convergence, a backup router immediately becomes the master router if the priority of the backup router is higher than the priority of the master router.
