Which network protocol is responsible for routing packets from one network to another?

A.    TCP
B.    UDP
C.    IP
D.    ICMP
E.    Ethernet

Answer: C
The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.

You display the IP interface information with ipmpstat -i.
Which two characteristics are indicated by characters that may be included in the FLAGS column?

A.    default route
B.    IP forwarding enabled IS
C.    allocated to global zone
D.    unusable due to being inactive
E.    nominated to send/receive IPv4 multicast for its IPMP group

Answer: DE
Indicates the status of each underlying interface, which can be one or any combination of the following:
(D) d indicates that the interface is down and therefore unusable.
(E) M indicates that the interface is designated by the system to send and receive IPv6 multicast traffic for the IPMP group.
i indicates that the INACTIVE flag is set for the interface. Therefore, the interface is not used to send or receive data traffic.
s indicates that the interface is configured to be a standby interface.
m indicates that the interface is designated by the system to send and receive IPv4 multicast traffic for the IPMP group.
b indicates that the interface is designated by the system to receive broadcast traffic for the IPMP group.
h indicates that the interface shares a duplicate physical hardware address with another interface and has been taken offline. The h flag indicates that the interface is unusable.

To inspect network interface net3, you enter the following commands:


What problem do you suspect? Assume the user is authorized and provided the correct password.

A.    The net3 interface hasn’t been enabled yet.
B.    The net3 vnic hasn’t been created.
C.    The net3/v4 ip object hasn’t been configured.
D.    The net3 interface is not attached to a NIC or etherstub.

Answer: C
The following command marks the address object net1/v4a up that was previously marked down.
# ipadm up-addr net1/v4a

What determines which bits in an IP address represent the subnet, and which represent the host?

A.    Subnet
B.    unicast
C.    netmask
D.    multicast
E.    broadcast

Answer: C
A subnetwork, or subnet, is a logically visible subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. The routing prefix of an address is written in a form identical to that of the address itself. This is called the network mask, or netmask, of the address. For example, a specification of the most- significant 18 bits of an IPv4 address, 11111111.11111111.11000000.00000000, is written as

You need to configure an ISCSI target device on your x86 based Oracle Solaris II system. While configuring the iSCSI device, the following error is displayed:

bash: stmfadm: command not found

Which option describes the solution to the problem?

A.    The COMSTAR feature is not supported on the x86 platform.
The feature is supported only on the SPARC platform.
B.    Use the iscsitadm command on the x86 platform when configuring an iSCSI target.
C.    Install the storage-server group package on this system.
D.    Start the iSCSI target daemon on this system.

Answer: C
STMF – Manages transactions, such as context and resources for Small Computer System Interface (SCSI) command execution, and tracking logical unit and port providers. STMF also handles logical unit mappings, allocating memory, recovering failed operations, enumeration, and other necessary functions of an I/O stack.
STMF is controlled by stmfadm, and stmfadm is the majority of the commands you will be using to administer COMSTAR (COmmon Multiprotocl Scsi TARget). Install the packages you need for COMSTAR with iSCSI and reboot:

# pfexec pkg install storage-server
# pfexec pkg install SUNWiscsit
# shutdown -y -i6 -g0

Note: You can set up and configure a COMSTAR Internet SCSI (iSCSI) target and make it available over the network. The iSCSI features can work over a normal Internet connection (such as Ethernet) using the standard iSCSI protocol. The iSCSI protocol also provides naming and discovery services, authentication services using CHAP and RADIUS, and centralized management through iSNS.
The COMSTAR target mode framework runs as the stmf service. By default, the service is disabled. You must enable the service to use COMSTAR functionality. You can identify the service with the svcs command. If you have not rebooted the server since installing the group/feature/storage-server package, the service might not be enabled correctly.

Your SPARC server will not boot into multi user-server milestones and you need to troubleshoot to out why. You need to start the server with minimal services running so that you can go through each milestone manually to troubleshoot the issue.
Select the option that boots the server with the fewest services running.

A.    boot -s
B.    boot milestone none
C.    boot -m milestone=single-user
D.    boot -m milestone=none
E.    boot -m none

Answer: D
The command boot -m milestone=none is useful in repairing a system that have problems booting early.
Boot Troubleshooting:
To step through the SMF portion of the boot process, start with:
boot -m milestone=none
Then step through the milestones for the different boot levels:
svcadm milestone svc:/milestone/single-user:default
svcadm milestone svc:/milestone/multi-user:default
svcadm milestone svc:/milestone/multi-user-server:default

user1 is attempting to assist user2 with terminating user2’s process 1234.

user1 entered the following: kill -9 1234

Why does the process continue to run?

A.    You can kill a process only if you are root.
B.    You can kill only a process that you own.
C.    You can kill the process only with the pkill command.
D.    You need to kill the process with a stronger kill signal.

Answer: B
Kill -9
Kill (terminates without cleanup)
Only works if issued by process owner or super user (root) The program cannot respond to this signal; it must terminate
Note: Unix provides security mechanisms to prevent unauthorized users from killing other processes. Essentially, for a process to send a signal to another, the owner of the signaling process must be the same as the owner of the receiving process or be the superuser.
