relationship between Router B and Router C?

• A. Full
• B. Down
• C. 2-way
• D. Attempt

Refer to the graphic, which of the following statements is true about OSPF topology and
configuration?

• A. Compared with R1, R2 is more likely to become the DR because the DR priority of the interface on R2 is lower than that of R1.
• B. After the default network type of the interface on R1 is restored to broadcast, a stable OSPF neighbor relationship can be set up between R1 and R2.
• C. After the default network type of the interface on R1 is restored to broadcast and the hello packet sending interval is changed to 10s, a stable OSPF neighbor relationship can be set up between R1 and R2.
• D. A stable OSPF neighbor relationship can be set up between R1 and R2.

The router ID of the OSPF-enabled router must be the same as the IP address of an interface on the
router.

• A. TRUE
• B. FALSE

With what kind of routers does a DRother router exchange link state information and route
information?

• A. DRother
• B. DR
• C. BDR
• D. All OSPF neighbors

• A. 13
• B. 15
• C. 14
• D. 12

Which of the following statements is true?

• A. Routers work at the physical layer.
• B. Switches work at the network layer.
• C. Switches work at the physical layer.
• D. Routers work at the network layer.

As shown in the figure, the host has ARP cache. Host A sends a data packet to host B. Which of the
following are the destination MAC address and destination IP address of the data packet?

• A. MAC-A, 11.0.12.1
• B. MAC-C, 11.0.12.1
• C. MAC-C, 10.0.12.2
• D. MAC-B, 11.0.12.1

Which of the following packets is used by OSPF to describe its link state database (LSDB)?

• A. LSR
• B. DD
• C. LSU
• D. HELLO

Assume that an OSPF-enabled router has no loopback interface configured. What would be used as
the router ID?

• A. The preference of the router
• B. The smallest IP address of a physical interface on the router (if configured)
• C. The IP address of the router's management interface (if configured)
• D. The biggest IP address of a physical interface on the router (if configured)

A routing entry contains multiple fields. Which of the following statements about these fields is
false?

• A. Pre: indicates the preference value of a routing protocol.
• B. NextHop: indicates the address of the local interface corresponding to a route.
• C. Proto: indicates the source of a route.
• D. Destination/Mask: indicates the address and mask length of the destination network or host.
