QUESTION 6
A server node in an Serviceguard cluster contains three LAN interface cards; two 100baseT Ethernet NICs and one 1000baseT gigabit Ethernet NIC, with the intent of providing a high speed data LAN with redundancy. What is a consequence of this LAN configuration?
A. The NICs for the data LAN and failover LAN must be identical.
B. The gigabit Ethernet and the 100baseT NICs cannot share the same subnet.
C. Three NICs are insufficient to provide redundancy for both the data and the heartbeat LAN.
D. The data packet size on the gigabit Ethernet is larger than the 1000baseT NIC and therefore will cause additional network latency.
Answer: A
QUESTION 7

node_b – pkg2 running
A. [node_a]#: cmhaltpkg pkg1
[node_b]#: cmhaltnode -f
[node_b]#: cmrunpkg -n node_b pkg1
[node_a]#: shutdown -h 0
B. [node_a]#: cmhaltpkg pkg1
[node_b]#: cmrunpkg -n node_b pkg1
[node_a]#: cmhaltnode
[node_a]#: shutdown -h 0
C. [node_b]#: cmhaltpkg pkg2
[node_a]#: cmhaltcl -f
[node_b]#: cmrunpkg -n node_b pkg1
[node_a]#: shutdown -h 0
D. [node_b]#: cmhaltpkg pkg1
[node_a]#: cmhaltcl -f
[node_ b]#: cmrunpkg -n node_b pkg1
