The system myhost needs to send data to printsvr. The routing table on myhost has no entry for printsvr. The routing table on myhost has no entry for the 200.55.42.0 network.

Which entry does the routing algorithm look for next?

  1. RARP

  2. ARP cache

C. 200.54.42.255

A new system administrator tries to determine the IPv6 IPMP configuration and sees the following:

# grep failover /etc/hostname6*

/etc/hostname6.hme0: -failover group mgrp6

/etc/hostname6.qfe0: -failover group mgrp6-1

/etc/hostname6.qfe1: -failover group mgrp6-1 Which statement is true?

  1. There has definitely been an error configuring hme0.

  2. The hme0 is a spare interface for the mgrp6-1 failover group.

  3. The system is configured so that notifications are generated when hme0 fails.

  4. Interface hme0 has priority over qfe0/qfe1 when doing a failover.

Answer: C

Given the following DHCP debug output:

3cdbd723: Datagram received on network device: hme0 3cdbd723: Reserved offer: 192.1.29.72

3cdbd724: Unicasting datagram to 192.1.29.72 address. 3cdbd724: Adding ARP entry: 192.1.29.72 == 080020CBCBCB

3cdbd724: Updated offer: 192.1.29.72

3cdbd725: Datagram received on network device: hme0

3cdbd725: Client: 01080020CBCBCB maps to IP: 192.1.29.72 3cdbd725: Unicasting datagram to 192.1.29.72 address.

A portion of the network you are managing is composed of a firewall system (fw-01) running the Solaris IP Filter firewall. The fw-01 firewall has a rule set to log and NAT the web-int system with IP 192.168.1.10/32 as web-ext with IP 129.157.1.10/32.

Because the fw-01 firewall is logging its activity, which Solaris IP Filter user-level utility must you run to print only NAT log records?
