• Question 21:

  You administer a server running a global zone with no virtual networking. Consider the following configuration:

  

  Which is a valid IPMP configuration for this server?

  A. net0 and net1 must be configured into an IPMP group, net2 can be configured into its own IPMP group, and net0 or net1 can be configured as a standby interface.

  B. net0 and net1 must be configured into one IPMP group, net2 and net3 must be configured into a second IPMP group, and all interfaces can be configured for link detection.

  C. net1 and net2 must be configured into an IPMP group, net0 can be configured into its own IPMP group, and net3 can be configured as a standby interface.

  D. net0 and net2 must be configured into an IPMP group, net0 can be configured into its own IPMP group, and net3 can be configured as a standby interface.

  Correct Answer: D

• Question 22:

  You added three interfaces to an IPMP group. You now want to review the failure detection modes. Which command most you use to determine if all interfaces in the group support link- based detection?

  A. ipadm show-ifprop

  B. dlstat show-link

  C. dladm show-link

  D. ipmpstat i

  Correct Answer: D

• Question 23:

  Your organization uses NFS to share data from Oracle Solaris servers to Oracle Solaris clients. The server currently has an NFS share configured for the rpool/export/data file system. A client is currently mounting this file system. As administrator, you add a new file system rpool/export/data/yesterdays_data, and copy data into the new file system. Which action is required for the client currently mounting the rpool/expor/data file system to access the new data?

  A. The rpool/export/data/yesterdays_data file system must be mounted.

  B. No action is required because the data is automatically made available.

  C. The rpool/export/data file system must be remounted.

  D. The nfs/client server must be restarted.

  Correct Answer: C

• Question 24:

  What are targets for IPMP probe-based failure detection configured by?

  A. responses to SNMP requests

  B. specifying host routes in the routing table

  C. specifying hosts in /etc/default/mpathd

  D. setting the property svc:/network/ipmp/config/transitive-probing

  Correct Answer: B

• Question 25:

  The default route for the NCP static is changed with the following command sequence:

  

  When does the entered route take effect?

  A. after the set command

  B. after the verify command

  C. after the commit command

  D. after the exit command

  E. after enabling the location user (command not shown)

  Correct Answer: C

• Question 26:

  How do you add a test address to an IPMP group?

  A. Use ipadm create-addr to add the address to a member interface.

  B. Use ipadm create-addr to add the address to the IPMP interface.

  C. Use ipadm create-ip to add an address to a member interface.

  D. Use ipadm create-ip to add an address to the IPMP interface.

  Correct Answer: B

• Question 27:

  Which two statements correct regarding Link Aggregations?

  A. The MAC address of the first configured link is used for all links.

  B. A link with an existing IP interface cannot be added to an aggregation.

  C. The switch must support the Link Aggregation Control Protocol (LACP).

  D. Links of differing bit rates can be aggregated, but performance gains may not be realized.

  E. The f option of dladm allows aggregating devices that do not support link state notification.

  Correct Answer: BE

• Question 28:

  You must configure your server to use IPMP with probe based failure detection enabled. Which statement is a valid constraint or feature that applies to this requirement?

  A. Link-based detection is supported only on Genetic Land Driver version 2 (GLDv2)-complaint NICs.

  B. GLDv2 NICs are not supported in Oracle Solaris 11.

  C. GLDv3 NICs configured for link based detection by default.

  D. You must first disable link based detection before configuring probe-based failure detection.

  Correct Answer: D

• Question 29:

  Your organization uses NFS to share data from Oracle Solaris servers to Oracle Solaris clients. For the nfsmapid daemon to work properly the client and server must be on the same domain. Select the location that has the highest precedence when the nfsmapid daemon searches for a domain name.

  A. the nfsmapid_domain parameter in the mapid SMF service.

  B. the nfsmapid_domain parameter in the /etc/default/nfs file

  C. the domain name in the /etc/default/domainname file, if it exists.

  D. a_nfsv4idmapdomain TXT record found by the configured domain name servers

  Correct Answer: C

• Question 30:

  Link aggregation and IP multipathing both offer some benefits for network performance and reliability. Identify two correct statements.

  A. IPMP requires full duplex, point-to-point links.

  B. A router is a single point of failure for link aggregation.

  C. Link aggregation allows a standby interface to be automatically enabled if another interface fails.

  D. Depending on load balancing algorithms, packets may not be balanced among all IPMP active interfaces.

  E. Link aggregation uses additional interfaces to improve performance, without requiring additional IP address.

  Correct Answer: DE
