CCNA 200-301 Practice Exam: Mixed Topics
Welcome to today’s CCNA 200-305 Practice Exam, where I’ll be testing (and reinforcing ) your knowledge of several different CCNA exam topics.
Which of these NAT terms best describes the 18.104.22.168 address shown in this exhibit?
A. inside local
B. inside global
C. outside local
D. outside global
On an ISL trunk, frames destined for what VLAN will be sent across the trunk untagged?
A. All of them.
B. Frames destined for the native VLAN (by default, VLAN 1).
C. None of them.
D. All frames except those destined for the native VLAN.
What term does RSTP use to describe the STP blocking state?
What is the binary equivalent of the hex value AA?
Which versions of OSPF allow you to indicate an area number on the interface rather than with the process ospf command?
A. Both v2 and v3.
B. v3, but not v2.
C. v2, but not v3.
D. Neither v2 nor v3.
Let’s have a look at the answers!
Answer 1: The inside global address (B).
The original address is the inside local address (as I mentioned in the illustration!), and the address that inside local address is translated to is the inside global address.
Answer 2: None of them (C).
One of the drawbacks of ISL is that all frames sent across an ISL trunk are tagged — even the frames destined for the native VLAN.
Answer 3: Discarding (C).
The STP blocking state is the equivalent of the RSTP discarding state.
Answer 4: 10101010 (B).
The hex value AA tells us we have 10 units of 16 and 10 units of 1. 160 + 10 = 170. The binary equivalent of 170 is 10101010. The 128, 32, 8, and 2 bits are set to 1, giving us a total of 170.
Answer 5: v3, but not v2 (B).
OSPF v3 (OSPF for IPv6, that is) allows you to place an interface into an OSPF area with an interface-level command, but OSPF v2 (OSPF for IPv4, that is) does not.
That’s it for today! See you tomorrow with another new CCNA Practice Exam!
