Refer to the shown below.
%PIX|ASA-3-105010: (Primary) Failover message block alloc failed • %PIX|ASA-3-106010: Deny inbound protocol src interface_name:dest_address/dest_port dst interface_name:source_address/source_port • %PIX|ASA-3-106011: Deny inbound (No xlate) string • %PIX|ASA-3-106014: Deny inbound icmp src interface_name: IP_address dst interface_name: IP_address (type dec, code dec) • %PIX-3-107003: RIP: Attempted reference of stale data encountered in function, line: line_num • %PIX|ASA-3-109010: Auth from inside_address/inside_port to outside_address/outside_port failed (too many pending auths) on interface interface_name. • %PIX|ASA-3-109013: User must authenticate before using this service • %PIX|ASA-3-109016: Can't find authorization ACL acl_ID for user 'user' • %PIX|ASA-3-109018: Downloaded ACL acl_ID is empty • %PIX|ASA-3-109019: Downloaded ACL acl_ID has parsing error; ACE string • %PIX|ASA-3-109020: Downloaded ACL has config error; ACE • %PIX|ASA-3-109023: User from source_address/source_port to dest_address/dest_port on interface outside_interface must authenticate before using this service. What statement is correct regarding the output shown in the graphic? |
A. These two log messages will not have a severity level. They are not errors but are just informational messages.
B. The first log message is categorized as a warning message. C. These messages regarding interface status are normal output and will always be displayed when you exit config mode. D. The first log message is an error message with a severity level of 3. E. The second message would be shown if the logging console warning command had been issued. |
Answer: D

Refer to the configuration statements shown in the graphic above.
R1(config)#access-list 199 permit tcp host 10.1.1.1 host 172.16.1.1 R1(config)#access-list 199 permit tcp host 172.16.1.1 host 10.1.1.1 R1(config)#end R1#debug ip packet 199 detail |
Which statement reflects what the effect is of this configuration sequence?
A. These commands will generate an error message because you cannot use an access list with any debug commands. B. These commands will have no effect at all. The debug ip packet command will work as normal and display info for all IP packets. C. These commands turn on debug ip packet only for packets between hosts 10.1.1.1 and 172.16.1.1. D. These commands will only work when you specify only one host rather than two. |
