examples/?wap2;PHPSESSID=6bab876c08055dc69f12fb005869478f Paul B: Some of this probably duplicates my original post.... here's some bits stolen from the Netscaler Advanced course..... Enter the following command in the shell to trim a newnslog file: nsconmsg -K input_file -s time=DDMMMYYYY:HH:MM -k output_file -T seconds -d copy Command example: nsconmsg -K /var/nslog/newnslog -s time=19Jan2009:17:00 -k slice1_newnslog -T 3600 -d copy This command writes newnslog entries from 5pm-6pm in the slice1_newnslog file. Enter the following command in the shell to view the time span of the current newnslog file: nsconmsg -K /var/nslog/newnslog -d setime Enter the following command in the shell to display event information, such as entity up/down, alerts and configuration saves: nsconmsg -K /var/nslog/newnslog -d event Enter the following command in the shell to view console messages, which include IP address conflicts and duplex mismatch, in the current newnslog file: nsconmsg -K /var/nslog/newnslog -d consmsg Enter the following command in the shell to display memory utilization: nsconmsg -s -K /var/nslog/newnslogConMEM=1 -d oldconmsg Enter the following command in the shell to display bandwidth information: nsconmsg -K /var/nslog/newnslog -s nsdebug_pe=1 -d oldconmsg Enter the following command in the shell to display load-balancing information: nsconmsg -K /var/nslog/newnslog -s ConLb=1 -d oldconmsg Enter the following command in the shell to view SSL stats for front-end connections: nsconmsg -K /var/nslog/newnslog -s ConSSL=1 -d oldconmsg Enter the following command in the shell to view SSL stats for back-end connections: nsconmsg -K /var/nslog/newnslog -s ConSSL=2 -d oldconmsg Enter the following command in the shell to view SSL stats for front- and back-end connections: nsconmsg -K /var/nslog/newnslog -s ConSSL=3 -d oldconmsg Enter the following command in the shell to display monitoring statistics: nsconmsg -K /var/nslog/newnslog –s ConMon=x –d oldconmsg This command gives basic information when x=1 and gives detailed information when x=2. Enter the following command in the shell to display content switching statistics: nsconmsg -K /var/nslog/newnslog –s ConCSW=1 -d oldconmsg Enter the following command in the shell to view all non-zero totals in the current newnslog file: nsconmsg -K /var/nslog/newnslog -d statswt0 | more Enter the following command in the shell to view the average rates in the current newnslog file: nsconmsg -K /var/nslog/newnslog –d current | more Use -g to grep for specific counters of interest. For example: nsconmsg -K /var/nslog/newnslog -g cpu -d statswt0 | more nsconmsg -K /var/nslog/newnslog -g arp –d current | more Enter following command in the shell to display CPU usage in the shell: nsconmsg -K /var/nslog/newnslog -s totalcount=200 -g cpu_use -d current Enter the following command in the shell to display NIC information: nsconmsg -K /var/nslog/newnslog -g nic -d current And watch out for the parameters: a "-k" and a "-K" (lower- vs upper-case) have VERY different meanings!!!! For example the UPPERcase "-K" refers to an input file, whilst the lowercase "-k" refers to an output file. Getting them wring could mean over-writing your log file!!! Ooops!
Q74. A network engineer selected the option on a SSL certificate to provide notification upon expiration of the certificate; however when a certificate expires, NO notification is sent to the engineer. Which step could the engineer take to enable notification?
A. Configure SNMP.
B. Create a SSL policy.
C. Enable the SSL offload feature.
D. Ensure that the certificate is linked to a Root certificate.
Answer: A
Q75. Which two of the listed statements are true about Access Control Lists (ACLs) on the NetScaler? (Choose two.)
A. Extended ACLs may BRIDGE traffic.
B. Simple ACLs are bound on ALL interfaces.
C. Extended ACLs are evaluated after creation.
D. Simple ACLs are processed after Extended ACLs.
Answer: A, B
Q76. Which statement is true about interface link-state on the NetScaler?
A. Interface link-state is controlled by ifconfig in BSD.
B. Interface link-state is dependent on the HAMON setting.
C. Interface link-state CANNOT be brought down from the NetScaler.
D. Interface link-state on both appliances is unaffected by the force failover command.
Answer: C
Q77. A network engineer has configured two NetScaler MPX appliances as a high availability (HA) pair. What can the engineer configure to prevent failover if only a single interface fails?
A. FIS
B. PBR
C. SNMP
D. VMAC
Answer: A
Q78. Scenario: A network engineer has bound four policies to an HTTP virtual server as follows: PolicyA is bound with a priority of 10 and has the following expression: REQ.IP.SOURCEIP
== 10.10.10.0 PolicyB is bound with a priority of 15 and has the following expression: REQ.IP.SOURCEIP != 10.10.11.0 PolicyC is bound with a priority of 20 and has the following expression: REQ.IP.SOURCEIP == 10.10.12.0 PolicyD is bound with a priority of 25 and has the following expression: REQ.IP.SOURCEIP != 10.10.13.0 When a connection is made from a PC with an IP address of 10.10.12.15, which policy will be applied?
A. PolicyA
B. PolicyB
C. PolicyC
D. PolicyD
Answer: B
Explanation:
Don't be fooled by this as the first policy to match will be used, in this case 10.10.12.15 is not
10.10.11.0 hence it statisfies policyB
Q79. Which feature could a Network Engineer configure in order to restrict client connections to a specific bandwidth limit?
A. Spillover
B. Rate Limiting
C. SureConnect
D. Filter Policies
Answer: B
