Excessive time lag between Cisco DNA Center and device: The time difference between Cisco DNA Center and the device IP Address has drifted too far apart. CiscoDNA Center cannot process the device data accurately if the time difference is more than 3 minutes.

In order to use a prefix-list in a route-map, we must use the keyword “prefix-list” in the “match”

statement. . For example:

match ip address prefix-list WAN_PREFIXES

Without this keyword, the router will try to find an access-list with the same name instead.

When R2 & R5 are route reflectors (RRs), routes from R4 & R8 are advertised to R5 and R5

advertises to R2. But R2 would drop them as R2 is also a RR. Therefore some routes are

missing on R1 to advertise to eBGP peers.

Good reference:

Route reflectors (RR) must be fully iBGP meshed so we cannot configure RR on both R1 and

R5.

We should choose routers at the center of the topology RRs, in this case R4 & R5.

A DHCP server that receives a DHCPDISCOVER message may respond with a DHCPOFFER message on UDP port 68 (BootP client).

…

In the event that the DHCP server is not on the local subnet, the DHCP server will send the DHCPOFFER, as a unicast packet, on UDP port 67, back to the DHCP/BootPRelay Agent from which the DHCPDISCOVER came.

A route received from one iBGP peer will NOT be advertised to another iBGP peer. Therefore R4 could not receive advertisement for network 192.168.100.0/24. We can overcome this BGP limitation by configuring R1 as a route reflector server and R4 as a route reflector client so that R1 sends advertisements for R4.

Let’s see how the “logging synchronous” command affect the typing command:

Without this command, a message may pop up and you may not know what you typed if that

message is too long. When trying to erase (backspace) your command, you realize you are

erasing the message instead.

With this command enabled, when a message pops up you will be put to a new line with your

typing command which is very

In fact in this question both answer A and answer C are correct but we believe answer A is the

better choice as it only allows PC-2 to telnet to terminal server. All other hosts are refused to

telnet to terminal server via sequence 20.

When the aggregate-address command is used within BGP routing, the aggregated address is advertised, along with the more specific routes. The exception to this

rule is through the use of the summary-only command. The “summary-only” keyword suppresses the more specific routes and announces only the summarized

route.

Required Min RX Interval: This is the minimum interval, in microseconds, between received BFD Control packets that this system is capable of supporting.

The Destination Guard feature helps in minimizing denial-of-service (DoS) attacks. It performs address resolutions only for those addresses that are active on the link,and requires the FHS binding table to be populated with the help of the IPv6 snooping feature.The feature enables the filtering of IPv6 traffic based on the destinationaddress, and blocks the NDP resolution for destination addresses that are not found in the binding table. By default, the policy drops traffic coming for an unknowndestination.
