Question 1

Which of the following statements about router IDs are true? (Choose two)

Accepted Answer

Each router in an OSPF network must have a unique router ID. A router ID is expressed in a 32-bit dotted decimal format.

Question 2

Which of the following statements regarding link-state database and routing-table of a "single" OSPF area are correct? (Choose two)

Accepted Answer

All routers in a single OSPF area have identical link-state databases, but their routing tables may differ based on their individual positions and paths to destinations.

Question 3

According to the default value of route preference on the VRP platform, which of the following represent the correct sequence for direct route, static route, RIP and OSPF if they are listed from high preference to low preference?

Accepted Answer

The answer of According to the default value of route...

Question 4

[RTA-GigabitEthernet0/0/0]nat outbound 2000 address-group 1 Refer to the configuration output. What does the value "2000" refer to?

Accepted Answer

The value "2000" refers to the ACL (Access Control List) number used in the NAT (Network Address Translation) configuration.

Question 5

Two routers are configured with OSPFv3. OSPFv3 is enabled on all interfaces of each router. Which of the following is true in the event that the network administrator does not configure a Router-ID?

Accepted Answer

The answer of Two routers are configured with OSPFv3. OSPFv3...

Question 6

Which of the following statements regarding the router ID in OSPF are incorrect? (Choose three)

Accepted Answer

The answer of Which of the following statements regarding the...

Question 7

Which of the following statements regarding the DR in an OSPF network are correct? (Choose two)

Accepted Answer

In OSPF, a Designated Router (DR) is elected on multi-access networks like Broadcast and NBMA to reduce the number of adjacencies. The election process is defined by the OSPF protocol, and not all OSPF areas require a DR, only specific network types.

Question 8

A web server in a private network is required to provide HTTP services to public users. The network administrator is required to configure NAT on RTA.  Which configuration should be used?

Accepted Answer

The answer of A web server in a private network...

Question 9

An administrator of a company supporting a large enterprise network wishes to implement OSPF on the network as opposed to RIP. Which of the following points should the administrator use to support his reasoning for this change? (Choose three)

Accepted Answer

OSPF has no hop count limitation, unlike RIP which is limited to 15 hops. OSPF uses link-state updates which are more efficient than RIP's periodic updates, resulting in lower overhead. OSPF also supports faster convergence due to its use of the Dijkstra algorithm.

Question 10

The administrator wishes to configure OSPF on a router in the network however the router has no loopback interface. Which value will be used as the router ID?

Accepted Answer

In OSPF, if there is no loopback interface configured, the router ID is chosen as the highest IP address of the router's active interfaces.

Question 11

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

Accepted Answer

The answer of With what kind of routers does a...

Question 12

Which of the following statements about a designated port working in RIPv2 multicast mode are true? (Choose three)

Accepted Answer

In RIPv2 multicast mode, the designated port receives RIPv2 multicast packets and does not receive RIPv1 broadcast packets or RIPv2 broadcast packets, as RIPv2 uses multicast for updates.

Question 13

In a network supporting IPv6, OSPF no longer supports which feature?

Accepted Answer

In OSPF for IPv6 (OSPFv3), authentication is no longer handled by OSPF itself but is instead managed by IPv6's inherent security features, such as IPsec.

Question 14

OSPF allows for "multiple" processes. By default, OSPF selects a process whose number is ( ).

Accepted Answer

OSPF selects process number 1 by default.

Question 15

NAPT allows for multiple internal addresses to be mapped to a single public address. How does NAT distinguish between the different private addresses when mapping to the same public address?

Accepted Answer

NAPT (Network Address Port Translation) uses the source port number to distinguish between different private addresses when mapping them to the same public address. Each connection is identified by a unique combination of the source IP address, source port number, destination IP address, and destination port number.

Question 16

A configured internal host of a private network wishes to access the internet. What must be configured on the enterprise network egress router in order to achieve this? (Choose all that apply.)

Accepted Answer

NAT (Network Address Translation) is required to translate private IP addresses to a public IP address for internet access. A default route is needed to direct traffic destined for the internet to the appropriate gateway.

Question 17

The network administrator attempts to add interface G0/0/1 on Switch A to Eth-trunk 1, however the command fails. Which of the following may cause this?

Accepted Answer

The answer of The network administrator attempts to add interface...

Question 18

Which of the following OSPF versions is specific to IPv6?

Accepted Answer

OSPFv3 is the version of OSPF that is specifically designed to support IPv6.

Question 19

Which of the following commands is used to display the OSPF neighbor relationship establishment?

Accepted Answer

The answer of Which of the following commands is used...

Question 20
