QUESTION: 1
Which three Cisco IOS commands are required to configure a voice gateway as a DHCP server
to support a data subnet with the IP address of 10.1.30.0/24 and a default gateway of
10.1.30.1/24? (Choose three.)

A. ip dhcp pool
B. subnet 10.1.30.1 255.255.255.0
C. ip dhcp pool data
D. network 10.1.30.1/24
E. network 10.1.30.0 255.255.255.0
F. default-gw 10.1.30.1/24
G. default-router 10.1.30.1
Answer(s): C, E, G
Explanation:
1) To configure the DHCP address pool name and enter DHCP pool configuration mode, use
the following command in global configuration mode:
Router(config)# ip dhcp pool name - Creates a name for the DHCP Server address pool and
places you in DHCP pool configuration mode
2) To configure a subnet and mask for the newly created DHCP address pool, which contains
the range of available IP addresses that the DHCP Server may assign to clients, use the
following command in DHCP pool configuration mode:
Router(dhcp-config)# network network-number [mask | /prefix-length] - Specifies the subnet
network number and mask of the DHCP address pool. The prefix length specifies the number of
bits that comprise the address prefix. The prefix is an alternative way of specifying the network
mask of the client. The prefix length must be preceded by a forward slash (/).
3) After a DHCP client has booted, the client begins sending packets to its default router. The IP
address of the default router should be on the same subnet as the client. To specify a default
router for a DHCP client, use the following command in DHCP pool configuration mode:
Router(dhcp-config)# default-router address [address2 ... address8] - Specifies the IP address
of the default router for a DHCP client. One IP address is required; however, you can specify up
to eight addresses in one command line.

Which four Cisco IOS commands are required to configure a DHCP server on a voice gateway

10.1.130.1/24, and the TFTP server is located at 10.1.5.2. (Choose four.)

A. subnet 10.1.130.1/24
B. ip dhcp pool voice
C. default-router 10.1.130.1
D. option 150 10.1.5.2
E. network 10.1.130.0 255.255.255.0

q 26 -- which of the following are true of virtual warehouses? I believe all 4 answers should be there. (i.e. resize while its running, change size after creation (i.e. scale up/down), also -- auto suspend & auto resume.

Q12 should be D. Prism Central applies storage policies to Categories. You need to tag the VMs and VGs in Categories. You might also attach VGs to VMs. When you apply different storage policies through different categories to a VG and VM tagged to each other, the storage policies are applied independently. The storage policy applied to the tagged VG does not affect the tagged VM and vice versa. https://portal.nutanix.com/page/documents/details?targetId=Prism-Central-Guide-vpc_2024_1:mul-cluster-storage-policy-pc-c.html
