Here are the answers to last Tuesday's first set of Cisco CCNA and CCNP practice questions!
CCNA:
Short answer: You want a standard ACL to permit traffic sourced from 172.10.20.0 /27, and deny all other traffic. Write an ACL that will do this.
Answer: We use wildcard masks for ACLs, so the ACL would look like this:
access-list 37 permit 172.10.20.0 0.0.0.31
A second line is unnecessary, since the implicit deny will stop all other traffic.
CCNP / BSCI:
Short answer: You are running RIPv2 and OSPF on a single router. Your RIP domain is carrying VLSM information in its updates and you want those subnets in your OSPF domain. After entering the command router ospf 1, what should your next command be? Only one command is needed to do this.
Answer: The correct configuration is redistribute rip subnets. Leaving the subnets option will mean that only classful networks will be redistributed into OSPF, and OSPF requires no seed metric to be set for redistribution.
CCNP / BCMSN:
Short answer: What global command enables Quality Of Service?
Answer: The global command mls qos.
CCNP / BCRAN:
Short answer: What command will immediately tell you whether the SPIDs and ISDN switch type have been successfully configured?
Answer: Our old friend show isdn status will give you this information. If you're having trouble with ISDN, this really is the first command you should run.
CCNP / CIT:
You want to simulate a planned change to your network in order to spot issues in advance. What online Cisco tool will help you do this?
A. Connectivity Solver
B. Connectivity Planner
C. Connectivity Baseliner
D. Network Planner
Answer: A. That's the job of the Connectivity Solver.
See you later this morning with more answers to last week's Cisco CCNA and CCNP practice questions!
To your success,
