Question 1.
An FCIP between two sites with MDS directors was successfully implemented. Dual FCIP links were connected between the two geographically separate sites. ITCertKeys.com was running a highly available IP network utilizing the HSRP protocol between their ingress/egress routers. Recently a network event caused ITCertKeys.com IT Networking team to change the IP load balancing/HA configuration from HSRP to VRRP. Since making the change the FCIP links have either been down, or worked only intermittently. 

Why would the change to the IP load balancing/HA configuration cause this behavior?

A. The VRRP needs to be implemented on the MDS switches
B. The VRRP protocol will represent the inbound link as a VIP
C. The HSRP and VRRP protocols make no difference with the MDS FCIP link
D. The VRRP protocol is encrypting all of the FCIP traffic and striping the FCIP headers as part of the encryption process

Answer: B

Question 2.

Question 4.
There are 12 Solaris hosts connected to two fabrics and a DMX2000. All the hosts are dual-pathed using Emulex HBAs. All 12 HBAs in each fabric are connected and zoned to one FA port. Each host is doing 2000 IOPS. Each I/O size is 64KB. Two of the hosts are receiving the following error in their /var/adm/messages file: SCSI transport failed: 
reason 'timeout': retrying command 

What do you advise ITCertKeys.com to do?

A. Use Unix command sysdef queue_depth command to increase the queue_depth
B. Reduce the queue depth of the HBAs reporting the SCSI retry messages in 
    /kernel/drv/lpfc.conf file
C. Reduce the queue depth of the HBA reporting the SCSI retry messages in 
    /kernel/drv/sd.conf file
D. Increase the queue depth of the HBAs reporting the SCSI retry messages in
    /kernel/drv/lpfc.conf file

Answer: B

Question 5.
