What is the adminitrative distance of EBGP route?
- A.
100
- B.
200
- C.
20
- D.
170
- E.
200
Correct Answer
C. 20Explanation
The administrative distance of a route is a measure of its trustworthiness or reliability. A lower administrative distance indicates a more preferred route. In this case, the correct answer is 20, which means that EBGP (External Border Gateway Protocol) routes have an administrative distance of 20. This suggests that EBGP routes are considered very reliable and trustworthy, making them a preferred choice for routing decisions.Rate this question:

What methods can be used to overcome IBGP full mesh requirement?(Choose Two)
- A.
Route Reflector
- B.
Conferedation
- C.
Hub and spoke
- D.
Partial mesh
- E.
Point to point
Correct Answer(s)
A. Route Reflector
B. ConferedationExplanation
Route reflectors and confederations are two methods that can be used to overcome the IBGP full mesh requirement.
1. Route reflectors: In a full mesh IBGP network, every router needs to establish a direct BGP session with every other router. This can become impractical and difficult to manage in large networks. Route reflectors address this issue by allowing routers to establish a BGP session with a selected set of route reflectors instead of every router in the network. The route reflectors then reflect the BGP updates to other routers, reducing the number of required BGP sessions.
2. Confederations: Similar to route reflectors, confederations also aim to reduce the number of required BGP sessions in large networks. In a confederation, the network is divided into smaller sub-autonomous systems, and each sub-autonomous system has its own internal BGP (IBGP) mesh. The sub-autonomous systems then establish external BGP (EBGP) sessions with routers in other sub-autonomous systems, reducing the overall number of required IBGP sessions.Rate this question:

When redistributing rip into OSPF what routes get redistributed into OSPF(choose all that apply)
- A.
Rip routes
- B.
Directly connected interfaces running rip
- C.
Static routes
- D.
Floating routes
- E.
Null routes
Correct Answer(s)
A. Rip routes
B. Directly connected interfaces running ripExplanation
When redistributing RIP into OSPF, the routes that get redistributed into OSPF are RIP routes and directly connected interfaces running RIP. RIP routes are the routes learned through the RIP routing protocol, while directly connected interfaces running RIP are the interfaces that are directly connected to the router and are running the RIP protocol. The other options, static routes, floating routes, and null routes, are not included in the redistribution process.Rate this question:

What type of LSA's are blocked in the totally stubby area? (choose all that apply)
- A.
LSA1
- B.
LSA2
- C.
LSA3
- D.
LSA4
- E.
LSA5
Correct Answer(s)
C. LSA3
E. LSA5Explanation
In a totally stubby area, only LSA1 and LSA2 are allowed to propagate, while LSA3, LSA4, and LSA5 are blocked. LSA3 is a summary LSA generated by an ABR to advertise routes from outside the autonomous system (AS). LSA5 is an external LSA generated by an ASBR to advertise routes from other AS. Since a totally stubby area is designed to reduce the size of the routing table and limit external routes, LSA3 and LSA5 are blocked to prevent unnecessary routing information from entering the area.Rate this question:

How can summarization be done in OSPF? (choose all that apply)
- A.
Area range
- B.
Virtual link
- C.
Summary address
- D.
Stub
- E.
Nssa
Correct Answer(s)
A. Area range
C. Summary addressExplanation
Summarization in OSPF can be achieved through the use of "area range" and "summary address". The "area range" command allows the aggregation of multiple subnets into a single summary route within an OSPF area. This helps in reducing the size of the routing table and improving network efficiency. Similarly, the "summary address" command can be used to summarize routes at the boundary between OSPF areas, allowing for efficient routing and reducing the number of entries in the routing table.Rate this question:

In frame relay what OSPF network type requires a neighbor statement?(choose all that apply)
- A.
Point-to-multipoint
- B.
Point-to-point
- C.
Broadcast
- D.
Non-broadcast
- E.
Physcial
Correct Answer(s)
C. Broadcast
D. Non-broadcastExplanation
The OSPF network types that require a neighbor statement in frame relay are broadcast and non-broadcast. In a broadcast network, OSPF routers can dynamically discover their neighbors without explicitly configuring them. However, in a non-broadcast network, such as frame relay, OSPF routers cannot automatically discover their neighbors. Therefore, a neighbor statement must be configured to establish adjacency between OSPF routers in both broadcast and non-broadcast networks.Rate this question:

MQC is a combination of which queuing mechanisms?(choose 2)
- A.
CBWFQ
- B.
PQ
- C.
Custome Queue
- D.
FIFO
- E.
In/out
Correct Answer(s)
A. CBWFQ
B. PQExplanation
MQC (Modular QoS CLI) is a feature in Cisco IOS that allows for the configuration of quality of service (QoS) parameters on a network device. CBWFQ (Class-Based Weighted Fair Queuing) and PQ (Priority Queuing) are both queuing mechanisms that can be used with MQC. CBWFQ allows for the allocation of bandwidth to different traffic classes based on defined policies, while PQ gives priority to certain traffic classes over others. Therefore, CBWFQ and PQ are the two queuing mechanisms that can be combined with MQC. The other options, Custom Queue, FIFO, and In/out, are not specific queuing mechanisms and are not compatible with MQC.Rate this question:

In MCQ how much bandwidth % can you reserve on an interface?
- A.
74
- B.
70
- C.
75
- D.
50
- E.
80
Correct Answer
C. 75Explanation
The correct answer is 75. In networking, bandwidth refers to the amount of data that can be transmitted over a network connection in a given time. Reserving bandwidth on an interface allows for prioritization of certain types of traffic, ensuring that they have sufficient bandwidth to function properly. In this case, the correct answer suggests that you can reserve up to 75% of the available bandwidth on an interface.Rate this question:

EIGRP Query can be stopped from propagating using?(choose 2)
- A.
Stub area
- B.
Different domain
- C.
Summarization
- D.
Passive interface
- E.
Shutdown
Correct Answer(s)
A. Stub area
C. SummarizationExplanation
EIGRP queries can be stopped from propagating using two methods: stub area and summarization. In a stub area, routers do not advertise external routes, which prevents EIGRP queries from being sent outside the area. Summarization involves aggregating multiple routes into a single route, reducing the number of queries that need to be sent. Passive interface, shutdown, and different domain are not valid methods for stopping EIGRP queries from propagating.Rate this question:

Which protocols have a default metric of infinity when other protocols are redistributed into them? (choose 2)
- A.
IS-IS
- B.
BGP
- C.
RIP
- D.
OSPF
- E.
EIGRP
Correct Answer(s)
C. RIP
E. EIGRPExplanation
RIP and EIGRP have a default metric of infinity when other protocols are redistributed into them. RIP (Routing Information Protocol) uses a hop count as its metric, and a hop count of 16 is considered infinity. EIGRP (Enhanced Interior Gateway Routing Protocol) uses a metric called "feasible distance," and a feasible distance of 4294967295 is considered infinity. Therefore, when other protocols are redistributed into RIP or EIGRP, their metrics are set to infinity.Rate this question:

What are RFC 1918 addresses?
- A.
Private address space
- B.
Public address space
- C.
VPN addresses
- D.
Null addresses
- E.
Loopback addresses
Correct Answer
A. Private address spaceExplanation
RFC 1918 addresses refer to a range of IP addresses that are reserved for private use within a network. These addresses are not routable on the internet and are commonly used for internal networks, such as those found in homes, offices, or organizations. They are designed to provide a limited number of unique IP addresses that can be used within a private network without conflicting with public IP addresses. This helps to ensure the security and integrity of private networks by keeping them separate from the public internet.Rate this question:

In a RR senario a non client will not advertise to which bgp peer?
- A.
Route-reflector
- B.
Ebgp
- C.
Non-client
- D.
RR client
- E.
Ibgp
Correct Answer
C. Non-clientExplanation
In a route-reflector (RR) scenario, a non-client will not advertise to the route-reflector peer. This is because a non-client does not have the capability to reflect routes to other peers. Only RR clients, which are configured with the "route-reflector-client" command, can advertise routes to the route-reflector peer. Therefore, the non-client will not advertise to the route-reflector peer.Rate this question:

How can you contain a smurf attack?
- A.
Nbar
- B.
Car
- C.
Shape
- D.
Pbr
- E.
Static route
Correct Answer
B. CarExplanation
A smurf attack is a type of Distributed Denial of Service (DDoS) attack where the attacker floods a target network with a large volume of ICMP echo request packets, using spoofed IP addresses of the victim. These packets are then broadcasted to a network that amplifies the attack, overwhelming the victim's network and causing it to become inaccessible. To contain a smurf attack, implementing Car (Committed Access Rate) can be effective. Car limits the bandwidth that can be used for certain types of traffic, including ICMP, preventing the attacker from flooding the network with excessive ICMP packets and reducing the impact of the attack.Rate this question:

Correct Answer
A. UrpfExplanation
Urpf (Unicast Reverse Path Forwarding) is a technique used to prevent spoofing attacks. It checks the source IP address of incoming packets against the routing table to ensure that the packet is arriving on the expected interface. If the source IP address does not match the expected interface, the packet is dropped. Urpf helps in verifying the authenticity of the source IP address and prevents attackers from impersonating other systems by spoofing their IP addresses.Rate this question:

How does eigrp do unequal load balancing?
- A.
Cef
- B.
Ip cef
- C.
Using variance command
- D.
Static routes
- E.
Route to null zero
Correct Answer
C. Using variance commandExplanation
EIGRP can achieve unequal load balancing by using the variance command. This command allows the router to consider paths with a metric that is higher than the best path. By setting a variance value, EIGRP will include paths with a metric that is up to that value times higher than the best path. This enables the router to distribute traffic across multiple paths, even if their metrics are not equal. This way, EIGRP can achieve unequal load balancing and optimize network performance.Rate this question:
