1. When the host first boots up, if it has been configured to use DHCP (which most hosts are), it will send a _____ message asking for IP information to be allocated.

Question 1 of 23

2. Routers can also be configured to obtain their IP address from a DHCP server, if required, although this is rarely done. The command to configure this is:

Question 2 of 23

3. A _____ is a grouping of IP addresses for a particular section of the DHCP network.

Question 3 of 23

4. DHCP offers ___ option values.

Question 6 of 23

7. The port number for SSH is?

Question 7 of 23

8. A difference when configuring named ACLs is that you always have to use the ip access-list command, unlike with numbered ACLs, where you could also use the simple access-list command.

Question 8 of 23

9. If you need more detailed information about the traffic that is being matched by the ACL entries, you can configure the ___ or ____ parameters to the relevant ACL entries.

Question 9 of 23

10. The NAT inside global address is the IP address of an internal host as it appears to the outside world.

Question 10 of 23

11. For NAT, the ACL is used to tell the router which addresses it can and cannot translate.

Question 11 of 23

12. HSRP version 2 uses the new Multicast address _____.

Question 12 of 23

13. Although HSRP version 1 advertises timer values, these values are always to the whole second, as it is not capable of advertising or learning millisecond timer values.

Question 13 of 23

14. HSRP primary gateway election can be influenced by adjusting the default HSRP priority of ___.

Question 14 of 23

15. HSRP allows administrators to configure multiple HSRP groups on physical interfaces to allow for load balancing. By default, when HSRP is configured between two gateways, only one gateway actively forwards traffic for that group at any given time.

Question 15 of 23

16. VRRP sends advertisements to the Multicast destination address ____, using IP protocol number ___.

Question 16 of 23

17. If more than ___ routers are configured as part of the VRRP group, the backup virtual router with the second-highest priority is elected as the master virtual router if the current master virtual router fails or becomes unavailable.

Question 17 of 23

18. QoS lets you increase bandwidth so you get the more out of what you have and provide predictable performance.

Question 18 of 23

19. In the default QoS mode, it is important to know that all traffic, including real-time traffic such as voice, will be delivered on a best-effort basis, and all traffic will use a single queue on the switch. The different queues will be described later in this chapter. This default behavior is verified using the ____ command.

Question 19 of 23

20. The QoS IP Precedence field values are used to imply a particular CoS. In essence, the higher the IP Precedence value (numerically), the more important the traffic.

Question 20 of 23

21. QoS ____ is used to differentiate one stream of traffic from another so that different service levels can be applied to different streams of traffic.

Question 21 of 23

22. Traffic Shaping usually delays excess traffic by placing it into a buffer or queue for transmission when the data rate has returned to normal.

Question 22 of 23

23. ____ is used to place packets into different software queues based on the QoS labels. After the traffic is classified and marked with QoS labels, it is assigned and placed into different queues based on those QoS labels
