Question 186

Your users are experiencing delay issues while using their main application that requires connections to remote hosts. You run the command uptime and get the flowing output:
1:07am up 346 day(s), 12:03, 4 users, load average: 0.02, 0.02, 0.01
Which command will be useful in your next step of troubleshooting?

Correct Answer: B
Test the remote connection with traceroute.
The Internet is a large and complex aggregation of network hardware, con-
nected together by gateways. Tracking the route one's packets follow (or
finding the miscreant gateway that's discarding your packets) can be dif-
ficult. traceroute utilizes the IP protocol `time to live' field and
attempts to elicit an ICMP TIME_EXCEEDED response from each gateway along
the path to some host.
This program attempts to trace the route an IP packet would follow to
some internet host by launching UDP probe packets with a small ttl (time
to live) then listening for an ICMP "time exceeded" reply from a gateway.
Reference: man traceroute

Question 187

When issuing the zonestat 2 1h is command, the following information is displayed:

Which two options accurately describe the statistics contained in the output?

Correct Answer: A,C
A: %PART The amount of cpu used as a percentage of the total cpu in a processor-set to which the zone is bound. A zone can only have processes bound to multiple processor sets if it is the global zone, or if psrset(1m) psets are used. If multiple binding are found for a zone, it's %PART is the fraction used of all bound psets. For [total] and [system], %PART is the percent used of all cpus on the system.
Note:The zonestat utility reports on the cpu, memory, and resource control utilization of the currently running zones. Each zone's utilization is reported both as a percentage of system resources and the zone's configured limits.
The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval.
Reference: man zonestat

Question 188

You are troubleshooting interface net3 and you enter the following sequence of commands:

Your next command should be:

Correct Answer: E
If you are assigning a static IP address, use the following syntax:
# ipadm create-addr -T static -a address addrobj
where addrobj uses the naming format interface/user-defined-string, such as e1000g0/v4globalz.
Note:
create-addr [-t] -T static [-d] -a {local | remote}=addr[/prefixlen], ... addrobj Creates a static IPv4 or IPv6 address on the interface specified in addrobj. If the interface on which the address is created is not plumbed, this subcommand will implicitly plumb the interface. The created static address will be identified by addrobj.
By default, a configured address will be marked up, so that it can be used as a source or destination of or for outbound and inbound packets.

Question 189

You want to deploy Oracle Solaris 11 with the Automated Installer (AI). You need to make sure that your server and network meet the requirements for using AI.
Identify two requirements for using AI.

Correct Answer: A,D
A: An automated installation of a client over the network consists of the following high-level
steps:
Step 1. The client system boots over the network and gets its network configuration and the
location of the install server from the DHCP server.
Step 2: The install server provides a boot image to the client.
Etc.
D: If two client machines need to be installed with the same version of the Oracle Solaris
11 OS but
need to be installed differently in other ways,then create two AI manifests for the AI install
service. The different AI manifests can specify different packages to install or a different slice as the install target,for example.

Question 190

The global zone has 8 CPUS. YOU suspect that one of your non global /ones, dbzone, is consuming all of the CPU resources. Which command would you use to view the CPU utilization for all of the zones to confirm this?

Correct Answer: A
If you're logged on to the system, you can run prstat -Z to generate a summary of cpu/memory utilization by zone.
