QUESTION 41
Internet Key Exchange (IKE) is responsible for which two functions? (Choose two.)

A.    Establishing network speed parameters
B.    Verifying the client’s patch level
C.    Negotiating algorithms to use
D.    Exchanging key information

Answer: CD
Explanation:
Internet Key Exchange (IKE) negotiates the IPSec security associations (SAs). This process requires that the IPSec systems first authenticate themselves to each other and establish ISAKMP (IKE) shared keys.
1. In phase 1 of this process, IKE creates an authenticated, secure channel between the two IKE peers, called the IKE security association. The Diffie-Hellman key agreement is always performed in this phase.
2. In phase 2, IKE negotiates the IPSec security associations and generates the required key material for IPSec. The sender offers one or more transform sets that are used to specify an allowed combination of transforms with their respective settings. The sender also indicates the data flow to which the transform set is to be applied. The sender must offer at least one transform set. The receiver then sends back a single transform set, which indicates the mutually agreed-upon transforms and algorithms for this particular IPSec session.

Explanation:
– Traceroute (tracert) outputs the list of traversed routers in simple text format, together with timing information.
– How is it possible for traceroute to timeout, yet the site will load fine in a browser? If a router along the way decides to not send the ICMP error message, you will get a timeout at that point in the traceroute. The router may pass on normal traffic, thus allowing your TCP-based http request to complete, but it may silently drop ICMP requests or errors, leaving your local traceroute process waiting and then timing out on that stop.

QUESTION 50
What are two characteristics of fiber optic cable? (Choose two.)

A.    Conducts electricity
B.    Requires metal conduit
C.    Supports splicing
D.    Requires a polish for end connectors

Answer: CD
Explanation:
C: A mechanical splice is a junction of two or more optical fibers that are aligned and held in place by a self- contained assembly (usually the size of a large carpenter’s nail). The fibers are not permanently joined, just precisely held together so that light can pass from one to another.
D: Modern connectors typically use a “physical contact” polish on the fiber and ferrule end. This is a slightly convex surface with the apex of the curve accurately centered on the fiber, so that when the connectors are mated the fiber cores come into direct contact with one another.
Note:
Optical fiber connectors are used to join optical fibers where a connect/disconnect capability is required. Due to the polishing and tuning procedures that may be incorporated into optical connector manufacturing, connectors are generally assembled onto optical fiber in a supplier’s manufacturing facility.

QUESTION 52
Which Microsoft network service can you use to establish a connection to a corporate LAN without any user action?

A.    VPN
B.    Remote Desktop
C.    DirectAccess
D.    Nap

Answer: C
Explanation:
DirectAccess allows remote users to securely access internal network file shares, Web sites, and applications without connecting to a virtual private network (VPN). An internal network is also known as a private network or intranet. DirectAccess establishes bi-directional connectivity with an internal network every time a DirectAccess-enabled computer connects to the Internet, even before the user logs on. Users never have to think about connecting to the internal network and IT administrators can manage remote computers outside the office, even when the computers are not connected to the VPN.

Answer:
passleader-98-366-dumps-532
Explanation:
– With a recursive name query , the DNS client requires that the DNS server respond to the client with either the requested resource record or an error message stating that the record or domain name does not exist. The DNS server cannot just refer the DNS client to a different DNS server.
– An iterative name query is one in which a DNS client allows the DNS server to return the best answer it can give based on its cache or zone data. If the queried DNS server does not have an exact match for the queried name, the best possible information it can return is a referral (that is, a pointer to a DNS server authoritative for a lower level of the domain namespace). The DNS client can then query the DNS server for which it obtained a referral. It continues this process until it locates a DNS server that is authoritative for the queried name, or until an error or time-out condition is met.

QUESTION 55
This question requires that you evaluate the underlined text to determine if it is correct. Select the correct answer if the underlined text does not make the statement correct. Select ‘No change is needed” if the underlined text makes the statement correct.
A secondary zone is the first DNS zone to which all updates for the records that belong to that zone are written.

A.    Primary zone
B.    Stub zone
C.    Conditional forwarding zone
D.    No change is needed

Answer: A
Explanation:
When a zone that this DNS server hosts is a primary zone, the DNS server is the primary source for information about this zone, and it stores the master copy of zone data in a local file or in AD DS.

Answer:
passleader-98-366-dumps-562
Explanation:
– TRACERT prints out an ordered list of the routers in the path that returned the ICMP Time Exceeded message.
– Ping, not tracert, determines packet loss.
– Tracert just displays the path to the target, not all connections.
– The TRACERT diagnostic utility determines the route taken to a destination by sending Internet Control Message Protocol (ICMP) echo packets with varying IP Time-To-Live (TTL) values to the destination. Each router along the path is required to decrement the TTL on a packet by at least 1 before forwarding it, so the TTL is effectively a hop count. When the TTL on a packet reaches 0, the router should send an ICMP Time Exceeded message back to the source computer.

QUESTION 57
You are setting up a network computer game. You need to open up ports on your firewall so your friends can join the network. Which command displays the ports that your computer is listening for?

A.    nslookup
B.    nbtstat
C.    ping
D.    netstat

Answer: D
Explanation:
Netstat (network statistics) is a command-line tool that displays network connections for the Transmission Control Protocol (both incoming and outgoing), routing tables, and a number of network interface (network interface controller or software-defined network interface) and network protocol statistics.
Incorrect:
Not A: nslookup is used for DNS troubleshooting.
Not B: nbtstat is designed to help troubleshoot NetBIOS name resolution problems.
Not C: ping is used to troubleshoot network connectivity.

passleader-98-366-dumps-592
Explanation:
– The localhost (loopback) address, 0:0:0:0:0:0:0:1, and the IPv6 unspecified address, 0:0:0:0:0:0:0:0, are reduced to ::1 and ::, respectively.
– A unique local address (ULA) is an IPv6 address in the block fc00::/7, defined in RFC 4193. It is the approximate IPv6 counterpart of the IPv4 private address.
– Link-local addresses for IPv4 are defined in the address block 169.254.0.0/16, in CIDR notation. In IPv6, they are assigned with the fe80::/10 prefix.

QUESTION 60
This question requires that you evaluate the underlined text to determine if it is correct. Select the correct answer if the underlined text does not make the statement correct. Select ‘No change is needed” if the underlined text makes the statement correct.
When a client computer is unable to reach a DHCP server, it will automatically assign an IP address in the 10.0.0.0 -10.0.0.255 range.

A.    127.0.0.0 – 127.0.0.255
B.    169.254.0.0 – 169.254.255.255
C.    192168.100.0 – 192.168.100.255
D.    No change is needed

Answer: B
Explanation:
169.254.0.0 – 169.254.255.255 is the APIPA address range. An APIPA address is used when the DHCP server is not available.
