Q

What is the sys-id-ext field in a BPDU used for?

A

To allow for the PVST+ to operate, there’s a field inserted into the BPDU to accommodate the extended system ID so that PVST+ can have a root bridge configured on a per-STP instance. The extended system ID (VLAN ID) is a 12-bit field.

int vlan 1
29
On which interface do you configure an IP address for a switch?
int vlan 1 ## Footnote The IP address is configured under a logical interface, called a management domain or VLAN 1, by default.
30
What is the valid host range for the subnet on which the IP address 192.168.168.188 255.255.255.192 resides?
192.168.168.129–190 ## Footnote The subnet is 128, the broadcast address is 191, and the valid host range is the numbers in between, or 129–190.
31
What is considered to be the inside host’s address after translation?
Inside global ## Footnote An inside global address is considered to be the IP address of the host on the private network after translation.
32
Which command will show you if your inside globals are allowed to use the NAT pool?
show access-list ## Footnote The command ip nat inside source must be used to say which inside locals are allowed to use the pool.
33
How many collision domains are created when you segment a network with a 12-port switch?
12 ## Footnote Layer 2 switching creates individual collision domains per port.
34
Which command allows you to set your Telnet password on a Cisco router?
line vty 0 4 ## Footnote This command places you in a prompt that will allow you to set or change your Telnet password.
35
Which router command allows you to view the entire contents of all access lists?
show access-lists ## Footnote To see the contents of all access lists, use the show access-lists command.
36
What does a VLAN do?
Breaks up broadcast domains in a layer 2 switch internetwork ## Footnote VLANs break up broadcast domains at layer 2.
37
If you wanted to delete the configuration stored in NVRAM, what command would you use?
erase startup-config ## Footnote This command deletes the configuration stored in NVRAM.
38
Which protocol is used to send a destination network unknown message back to originating hosts?
ICMP ## Footnote ICMP is the protocol at the Network layer that is used to send messages back to an originating router.
39
Which class of IP address provides 15 bits for subnetting?
B ## Footnote Class B provides 16 bits, but only 14 are available for subnetting.
40
What DNS record do you need to create for APs to automatically discover the WLC?
